Why is my desktop environment unresponsive for 3 minutes?

Big Scorpio · 2024-12-27 01:33:57

Hello Arch Friends,

I'll simplify the problem i mentioned earlier.
I am using KDE as my desktop environment.
I believe zram is active. I set it to ON as per default when using the archinstaller

cat /proc/swaps
Filename                                Type            Size            Used            Priority
/dev/zram0                              partition       4003324         0               100

i notice, that the OS has created no swap partition. I am unsure if that is the nature of the problem.

My problem is that my desktop environment freezes and is unresponsive to any action. Not even any hovering effect. not even a click and drag on the desktop background functions but i can move the cursor freely and interact with the currently visible programs on the foreground. i observed the time to be 20:10 and it became responsive as soon as I saw the time was 20:13. This is unacceptable.
What's the reason for such system unresponsiveness? This is happening regularly since I started using Arch Linux.

Where?

If you end up running OOM, yes.

Though

What you describe sounds as if it only affects the desktop shell (plasmashell) specifically?
The predominant reason for that is some desktop shelll widget thing.

=> check your system journal after such stall

sudo journalctl -b -e

I figured that was too much information at once, so i restarted but small this time.

OOM as in out of memory? I've got 8 GB RAM for now. I may try setting up a swap partition to see if there's any difference. Unless that conflicts with zram but i am not experienced enough to know what zram does and whether swap is compatible with it.

If that's what the system menu bar with the tray at the bottom is called, then yes.

I'll try once I encounter it again. Today it didn't happen. However I see this

And I see those messages even when I'm on the Arch Linux installation media on the USB drive, a live environment if you will.

Does it happen when your zram is heavy loaded/used?

You may try some lightweight DE to see if it also happens.

Does your usb ports stop working? If yes, then see here: https://askubuntu.com/questions/1359116 … ltiple-dev

This is why shopping list threads are heavily discouraged

You should take this serious: https://bbs.archlinux.org/viewtopic.php?id=302043

Well, i decided to reinstall Arch with Full Disk Encryption as i was missing it and planned to do so after the install. Pfft. I wish. The f2fs file system cannot be shrunk yet and i spanned it over my whole SSD, leaving no room for FDE. So I had to redo it all from the beginning.
Now, I'd love to comply with your suggestions but I have encountered a more serious problem now. I can't access my encrypted drive. See my new blocking problem here -> https://bbs.archlinux.org/viewtopic.php … 4#p2216984

Still, I understood from you, that I'll have to fiddle around with the USB connectors to see which one of them is being 'faulty', meaning pulling out and plugging in again one by one until this nagging message vanishes.
xerxes_, The USB ports all work fine and all USB devices I have connected are functional. I don't really think it's a HW issue on the motherboards part. On my Windows system I see no such message appearing or io stalling.
Still, I will deduce it today and report back.

You can also bisect them (yank half them to check which half includes the bogus one) but kind pointless if you're "three" or so

Big Scorpio · 2025-01-03 07:50:17

Alright, I got back now that FDE works at last. I hope ya'll had a good start into the new year.

I did as you suggested seth and temporarily disconnected every single USB device on my machine while running

sudo dmesg -wH

In parallel to monitor if anything has changed.
I did all that and this USB cannot enable message never stopped printing. It appears, that none of my USB devices are connected to that port:

I shortened the output here but you'll have to take my word when I say the USB cannot enable message was printing before and after the disconnect and reconnect of the USB devices - one by one.

If I am logically thinking about it, if that port is unused, can i just persistently disable it as a workaround to deal with the delayed IO problem?

If that port number is referring to the frontal USB connectors, I do not have any frontal USB connectors handy, meaning the Motherboard's section responsible for the frontal USB and Audio connectors is not connected to anything.

UPDATE
To the initial point with the "sudo journalctl -b -e" part I got more data on that.

(1) I went AFK. My System has suspended as a result of that. I came back later and the screens were blank and my Keyboard and mouse didn't have their RGB lit up. I attempt to wake it up with random keystrokes. Keyboard & Mouse's LED are lit. 2 Minutes pass before I see the login screen. I log in and immediately perform "sudo journalctl -b -e" I had prepared on the terminal to execute right away. Here's the output:

I did all that and this USB cannot enable message never stopped printing. It appears, that none of my USB devices are connected to that port:

USB is a bus, not a plug - this might be some internal device :\

If that port number is referring to the frontal USB connectors, I do not have any frontal USB connectors handy, meaning the Motherboard's section responsible for the frontal USB and Audio connectors is not connected to anything.

Can you disable it in the firmware/bios?
There's also not just a cable attached and dangling inside the case?

If I am logically thinking about it, if that port is unused, can i just persistently disable it as a workaround to deal with the delayed IO problem?

You could try to deauthenticate the entire bus, https://www.projectgus.com/2014/09/blac … rom-linux/

However, that error seems a constant and therefore it might be not directly related to your intermittent(?) stalls.

looks worse itr.

Disable bitwarden, see whether you get more stalls.
If so, please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

not just some segments.
Also your Xorg log, https://wiki.archlinux.org/title/Xorg#General

I didn't see such an ability in my BIOS and my Hardware is still on the modern range. No such cables are connected to nothing.

It gets better (sarcasm).
Now I am not even able to log in anymore. All I see is blank screen and my cursor, that i can move around. Waited for 10 minutes, rebooted several times. Same crap. I'm completely locked out.
Last I remember doing before starting up my Arch Linux OS was performing "pacman -Syu" and "killall plasmashell" (it was stalling again for too long) followed by running plasmashell in the terminal to bring it back up.

seth wrote:

Disable as in disabling Bitwarden, the service or disabling the program itself? I couldn't find any documentation about disabling bitwarden as a program. The only alternative meaning I can understand from this is uninstalling bitwarden. We'll cross that bridge once I get inside the system again.

I caught the Xorg log here by jumping to it from the arch install live environment.
http://0x0.st/8iAg.txt
journalctl captures only the live environment itself even if using arch-chroot into the installed OS.

That's your session or the kwin compositor - not that severe.
You're gonna be able to switch the VT and log into the console look around there.
You can probably even log into a GUI session as different user (this is typically configuration thing or some bogus extension)
The system journal will likely have records of something crashing or errors of any kind.
For X11, try to press "SHIFT+Alt+F12" to toggle the compositor.

https://archlinux.org/packages/extra/x86_64/bitwarden/ doesn't seem to ship a service, so just don't run it and make sure it's not in some autostart system (session restorage)

You're running on the nvidia GPU and your outputs are all attached there.
The intel one would be present for prime, but that's pointless - you could disable it, but nothing there looks like major trouble and the simpledrm device doesn't show up either.

People have/had issues w/ nvidia fbdev, though.
Try to add "nvidia_drm.modeset=1 nvidia_drm.fbdev=0" to the https://wiki.archlinux.org/title/Kernel_parameters (not! the modprobe.conf)

That key combo did absolutely nothing.
I did try something else. I pressed CTRL + ALT + F3 as I saw being suggested on a linux subreddit.
But that terminal display was shown only *after* i modified the kernel parameters for grub and regenerated grub config.
I was able to enter the OS through the terminal and obtain the system journal. Here it is: https://0x0.st/8iMj.txt

Furthermore on status check on SDDM i saw, that sddm-helper exited with 127. Greeter stopped. SDDM::Auth::HelperExitStatus(127). Although it was enabled and running. Probably normal behavior.
Yes, I'm currently using X11 per old habit. I wonder if using Wayland would work and be less of a pain in the ass?

seth · 2025-01-05 09:08:29

It does toggle the kwin_x11 compositor, provided kwin_x11 is actually running at the time. You however won't get any visual feedback if the compositor isn't the problem and there're just absolutely no windows to composit.

The problem wasn't that you can't login - at least there's no attempt to login from SDDM.
So the problem is likely SDDM and the cause is likely

Gah, that figures. I set the [Theme] Current to "breeze" in "/etc/sddm.conf.d/kde_settings.conf" and rebooted. Now i'm back in the desktop environment.

Now, seth, i need a little hand holding here with deauthorizing the seemingly unused USB bus "usb2-port1". How do I target that specific USB bus? From what I dug through I came only so far:

// Listing USB buses here

[motherfucker_big_scorpio@Nexus ~]$ 

// ChatGPT's suggestion to deauthorize usb2-port1 goes like so
#echo "0" | sudo tee /sys/bus/usb/devices/usb2-1/authorized
// i see no such directory under "/sys/bus/usb/devices/"

// Listing sys classes for USB

[motherfucker_big_scorpio@Nexus ~]$ ls /sys/class/usbmisc/
hiddev0  hiddev1
[motherfucker_big_scorpio@Nexus ~]$ 

// information from udevadm

[motherfucker_big_scorpio@Nexus ~]$ udevadm info -a -p /sys/class/usbmisc/

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

  looking at device '/class/usbmisc':
    KERNEL=="usbmisc"
    SUBSYSTEM=="subsystem"
    DRIVER==""

  looking at parent device '/class':
    KERNELS=="class"
    SUBSYSTEMS==""
    DRIVERS==""
    ATTRS{devcoredump/disabled}=="0"
    ATTRS{drm/version}=="drm 1.1.0 20060810"
    ATTRS{zram-control/hot_add}=="(not readable)"
    ATTRS{zram-control/hot_remove}=="(not readable)"

According to ChatGPT, which in my experience has limited usefulness on Advanced Linux System Administration topics, it suggested me to blacklist the USB bus like so as an alternative but I am not sure if the udev blacklist rule is precise enough to disable only usb2-port1 and not the whole usb2 row because disabling the entire usb2 row is not what i want to do.

ChatGPT wrote:

Create a custom udev rule file, e.g., /etc/udev/rules.d/99-disable-usb2-port1.rules
Add the following content to it:
ACTION=="add", SUBSYSTEM=="usb", KERNEL=="usb2", ATTR{authorized}="0"
This will prevent the device from being authorized as soon as it’s connected.

I will also follow your instructions and exit Bitwarden and see when i encounter the next system hiccup and post you the contents of both

sudo journalctl -b | curl -F 'file=@-' 0x0.st
cat /var/log/Xorg.0.log

Or do you no longer need the contents of Xorg the next time as i've provided these prior?

Thanks for the assistance so far.

Big Scorpio · 2025-01-06 13:09:22

Also please note, that a relevant problem to my main problem here is that plasmashell takes long to show up to be responsive and usable when I boot up my computer and log in normally through sddm(-helper). I captured the journalctl contents here: http://0x0.st/8iJ8.txt

See the time delta between when i log in and when the plasma shell first became usable. That's 2 minutes of waiting.
Last time I remembered to quit bitwarden (i have explicitly selected "Quit Bitwarden" on the top dropdown menu) in order to isolate this case of my system's unresponsiveness before shutting down my computer.

One rather obvious thing to fix would be your https://wiki.archlinux.org/title/Locale

lcoalectl; locale; locale -a

maybe see https://wiki.archlinux.org/title/Locale … g_language

But there's no obvious stall, plasmashell just takes ages to go through the plasmaoids

while you're getting IO errors from that usb device.

it suggested me to blacklist the USB bus

Blacklisting usbcore will certainl rid you of that probm. And the usb bus.

ChatGPT's suggestion to deauthorize usb2-port1 goes like so

You'd have to block the entire hub, usb2 - did you try to remove the external drives that seem attached there?

I was wondering about seeing that too just recently. Didn't think it would be problematic since Qt uses C UTF-8 as fallback?

I don't remember KDE Plasma being that slow back in 2018-2019 on CentOS 7. It was as quick as Windows.
Do I take this particular issue up with the KDE community or developers then since that's their part?

I'd really hate to do this.
But yes, I did remove all connected USB devices/cables from it and in dmesg the spam message never stopped.
However I've got some news on that matter. I was able to identify which bus & ports correspond to the USB connectors like so:

[motherfucker_big_scorpio@Nexus ~]$ lsusb

Bus 2 in my case is an external USB Hub device, that splits into 4 more USB 3.0 sockets (or ports as the system calls it), connected to the backpanel of my motherboard. All 4 sockets were connected to something:
Port 1 -> USB to USB Type C datalink cable & charging device for my smartphone, which was not connected to anything (and I can't make data transfers with Linux from/to it out of the box)
Port 2 -> USB to external Soundcard for Audio
Port 3 & 4 -> USB Flash Drives

I disconnected that USB to USB Type C Cable, that was not connected to anything. dmesg still reports

usb usb2-port1: Cannot enable. Maybe the USB cable is bad?

???

seth · 2025-01-07 10:27:18

en_CH isn't a locale?

I disconnected that USB to USB Type C Cable, that was not connected to anything. dmesg still reports

Even after a reboot?

Bus 2 in my case is an external USB Hub device

Have you tried to remove that thing entirely?

(We primarily want to know whether the unresponsive usb is the source of your plasma slowdowns)

I thought so too. ChatGPT doesn't know Linux all that much. I should take it less serious from that AI. Disregard this part.

Yes. I tested that today. dmesg is still spamming that.

That's what I intend to do next. Disconnecting the USB hub, reboot and then will report back.

In the meantime I have one more update with the stalling. Conditions are:
USB Hub connected. Port 1 of USB Hub is free (no cables attached there).
Bitwarden was quit before I went AFK at 17:20

Came back from being AFK at 19:49, the sddm login screen took it's sweet time to show itself in order to log me in. I logged in.
plasmashell was stalling again for almost 3 minutes. Later it even crashed when i clicked on the Application Launcher (i pressed the Windows key on the keyboard to make it happen).

Will report again to see if it's going to be different without the USB Hub being attached.

Did I miss to do something?

en_CH is still not a thing?
You can have de_CH,fr_CH and it_CH - I know there's a 4th language but whatever that's supposed to be, it's not english

plasma crash-aborted after losing the GL context which is likely related to

the zero-size rect there heavily implying that you lost every output - typically kscreen removing them after they unregistered in response to DPMS (try to disable kscreen, but I don't think that's related to your overall problem)

Edit: the errors in the "dump" seem to suggest some IO trouble - pointing at the USB device again…

I think not. Not, that i've seen in in the locale.gen. In KDE's Region and Language Settings I set the locales to en_CH.UTF-8 as they popped up on the list and match the way i interpret things.

Well, I did it now with the USB Hub completely disconnected from the motherboard and then rebooted.

I found, that the system booted up double as fast and the plasmashell was ready to go shortly after logging in - just the way i expected. The USB port error also didn't show up.
I let it go AFK again (i think it was hibernating or something?) at

22:47:32 Nexus systemd-logind[736]: The system will suspend now!

Came back and woke it up at

Jan 07 23:18:10 Nexus kernel: Freezing user space processes
Jan 07 23:18:10 Nexus kernel: Freezing user space processes completed (elapsed 0.001 seconds)
Jan 07 23:18:10 Nexus kernel: OOM killer disabled.

Now this USB port warning shows up out of nowhere again as you can see AFTER i woke it up.
And the locale warnings with "C" have not vanished either.
Running "locale" yields the same as before but with "LC_ADDRESS=en_CH.UTF-8" this time. I don't know where it gets that non UTF-8 "C" from.

Problem persists.

Might really blacklist USB Bus 2 and then plug the USB Hub elsewhere.

seth · 2025-01-08 00:23:37

as they popped up on the list and match the way i interpret things

https://wiki.archlinux.org/title/Locale … g_language

grep CH /etc/locale.gen

en_CH.UTF-8 is not a valid locale unless you added a custom one.
Get rid of that.

Then please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

I let it go AFK again (i think it was hibernating or something?) at

On my Windows system I see no such message appearing or io stalling.

Gahhh… 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Make that Gah 2. Apparently Windows did not disable fast startup initially. The

powercfg /H off

did nothing. I'm not taking any chances this time -> https://imgur.com/a/929hO5F
I also saw, that i must strictly shut down the machine for the effects to take place.

Continuing ...
Update:

I complied seth. In short, I believe the stalling is really caused by the USB2 port1 message spamming nature, in which I find it unknown whether it's the HUB Device or the cable to it or Windows Fast Boot intervening somehow.

I deauthorized usb2-port1 by running

echo 'ACTION=="add", SUBSYSTEM=="usb", KERNEL=="usb2", ATTR{authorized}="0"' > /etc/udev/rules.d/99-disable-usb2-port1.rules

dmesg no longer reports these spam after rebooting. The bootup time and log in is as swift as in Windows again. This behavior is in fact identical to before changing my locales to (i did this too)

As a consequence the USB devices connected to the USB Hub are no longer functional regardless to which USB port I plug it in to my motherboard's back panel. Keyboard and Mouse function normally.

However I ran out of time today to test it going into a sleep or hibernate like state and coming back from being AFK long enough. Will have to continue this the following day.

Here's the journalctl -b now -> http://0x0.st/8-8s.txt
As you can see, the texts

journalctl -b wrote:

Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.

Have not vanished.

Note for myself:
1) Figure out what to do next with the USB Hub and the devices I plug into it
2) I need to install an additional locale in English language but in European format and start using it. US formats aren't for me.

Alright, I did it again. Went AFK and came back hours later. System is still stalling. On top of that before I got to see the login screen several minutes have passed. Plasmashell is unresponsive for several minutes too.
Conditions are USB2 Port1 is deauthorized, so no more spam messages.
And the locale's are just like i posted 1 post previously.

Here is the journalctl -b -> http://0x0.st/8-cY.txt

I'm thinking of disabling hibernation & sleep. It's too much of a pain in the ass on the regular. Either that or downgrade KDE to a more stable and workable version somehow.

I'll retest again with kscreen disabled

No, I won't. I've had enough for now. Maybe sometime later I'll revise this again unless we're getting close to get to the bottom of these issues.
I'll disagreeably settle for less by disabling usb2-port1 and disabling f#@&ing hibernating before I'll waste another hour or so.

Still, the login screen after AFKing takes a minute to be interactive until i can type my password and enter. Got no data to provide it for now. Still 1 minute is better than what feels like a boring class in high school.
