startx crash

borrate · 2022-07-01 13:52:58

The first time that I execute startx, it crashes and takes me back to the terminal. If I run it again it works. This happens everyday.

I would like to know how can I troubleshoot and, hopefully, fix this issue.
Thanks in advance.

I'd suspect a potential race condition in the module loading *especially* if the attempt to launch X that fails is an auto-start setup in your profile or shellrc with autologin.

If this is the case, the solution is "early" loading of the DRM module in the initramfs:

Thank you Trilby.

I tried what you suggested and added the Nvidia modules to /etc/mkinitcipio.conf and ran /usr/bin/mkinitcpio -P

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

I also added the kernel parameter nvidia-drm.modeset=1 but the problem persists. I checked Xorg.0.log.old and journalctl -p 3 -b and its exactly the same error.

What else can I look for?

Thanks again.

seth · 2022-07-05 14:54:20

Please post the entire xorg log and a system journal (sudo journalctl -b), you can use the tip in the first link below.
I guess this is is an optimus system?

borrate · 2022-07-05 16:06:23

Hello Seth, it's a desktop PC
Here are the logs you requested.

Xorg.0.log.old
Xorg.0.log This is the one after running startx the second time, successfully
sudo journalctl -b

Thank you and let me know if you need more info.

seth · 2022-07-05 16:20:41

1. remove /etc/X11/xorg.conf - it's just gonna blur the error and I don't see any meaningful option in it (and even if, the static config would still not be a good way to apply such)
2. neither of the logs show "nvidia-drm.modeset=1" in the kernel command line (though it's in the journal) so the logs are maybe dated (but the crash is in the journal)
3. You've at least networkmanager and dhcpcd enabled, pick one, disable the other (there seems no wifi, so just dhcpcd will do) - reboot and see whether the issue remains.

borrate · 2022-07-07 11:55:41

1. I removed /etc/X11/xorg.conf. It was created by nvidia-settings
2. You're right, when I added nvidia-drm.modeset=1 I didn't realized that the log location changed from /var/log to .local/share/xorg
3. I disabled dhcpcd because I use network-manager-applet

Here are the updated logs
Xorg.0.log
Xorg.0.log.old
journalctl -b

seth · 2022-07-07 12:12:23

Ok, the system is "clean" now, but the issue remains.
I suspect it to be around rtkit-daemon and the HDMI output (circumstantial evidence, the event proximity and nvidiaUnlock releasing some mutex) - do you use the HDMI for audio?

borrate · 2022-07-07 13:02:02

I don't use HDMI for audio. Only usb for output and the front panel mic jack

seth · 2022-07-07 13:10:00

Try to blacklist snd-hda-codec-hdmi, https://wiki.archlinux.org/title/Kernel … acklisting (use the /bin/true method) and see what happens.

borrate · 2022-07-07 15:34:42

I created /etc/modprobe.d/blacklist_snd_hda_codec_hdmi.conf with the line

install snd_hda_codec_hdmi /bin/true

I ran mkinitcpio -v to ensure that the file was being loaded and then run mkinitcpio -P

Then I turned off an on the computer and startx didn't work so I saved those logs:
Xorg.0.log
Xorg.0.old.log

Then rebooted and startx worked the second time as usual. Here are the journals:
journalctl-b-1
journalctl-b

I was going to enter a virtual meeting and found out that the mic wasn't working but the usb audio output was. I deleted the blacklist and rebooted and the microphone worked.

seth · 2022-07-07 15:50:01

Then let's just throw some s…tuff against the wall:
- remove xf86-video-vesa
- disable docker
- delay the first startx call (ie. boot the mutli-user.target, login, get a cup of coffe, startx)

Does any of this impact the behavior?

borrate · 2022-07-08 12:29:53

- pacman - R xf86-video-vesa: it still crashes
- systemctl disable docker: it still crashes
- login, wait 1 min, startx: it doesn't crashes. I tried 3 times to be sure, powering off the computer before each try.

I think you may be getting somewhere. How can we check what happens after login?

seth · 2022-07-08 15:22:32

Well, there's *some* race condition for pretty much sure - it's just not the late KMS.

I'll just blame lennart:

Jul 07 09:41:00 sopapo pulseaudio[1301]: No such profile: output:hdmi-stereo-extra3
Jul 07 09:41:00 sopapo pulseaudio[1301]: Failed to initialize daemon due to errors while executing startup commands. Source of commands: /etc/pulse/default.pa

Check /etc/pulse/default.pa and make it not use hdmi-stereo-extra3 as default profile.

borrate · 2022-07-10 23:59:31

After that change, the pulseaudio error is gone but the startx issue persists
Where else could we look?

Lone_Wolf · 2022-07-11 10:57:20

The journals posted sofar have Too Much Information

- ensure docker is still disabled
- add audit=0 as kernel paramater to the boot command
(Combining those 2 things should make the journals much more readable )

boot, run startx fast
reboot, login, wait few minutes and run startx

post both journals .

borrate · 2022-07-11 13:35:04

Hello Lone_Wolf, here are the requested journals:
journalctl -b error
journalctl -b no error

Lone_Wolf · 2022-07-12 11:01:06

Your processor is an i5-8400 that usually comes with an intel integrated GPU.

In the logs there's no sign of an iGPU, did you disable it in bios or is this your processor a variant without iGPU (like a Xeon) ?

please post lspci -k as normal user to clarify what hardware linux sees on your machine.

Jul 11 09:28:13 sopapo systemd-udevd[268]: nvidia: Process '/usr/bin/bash -c '/usr/bin/mknod -Z -m 666 /dev/nvidiactl c $(grep nvidia-frontend /proc/devices | cut -d \  -f 1) 255'' failed with exit code 1.
Jul 11 09:28:13 sopapo systemd[1]: Found device TOSHIBA_HDWD110 Toshiba-1.

These messages are suspicious, but present in both logs .

It's a "shot in the dark" , but try disabling rtkit-daemon.service .

borrate · 2022-07-12 12:18:21

Yes, it comes with an integrated GPU and I don't recall having disabled it, just installing NVIDIA drivers.
Here is the output of lspci -k

I disabled rtkit-daemon but the problem persists, should I keep it disabled?

Lone_Wolf · 2022-07-12 13:18:58

Nope, you can restore rtkit .

There's no sign of the iGPU in lspci also, this is getting weird .

Could you boot with arch installation iso and check if lspci there does see your iGPU ?

Jul 11 09:28:12 sopapo kernel: DMI: Micro-Star International Co., Ltd. MS-7B24/B360M BAZOOKA (MS-7B24), BIOS 2.10 04/02/2018

Your bios firmware version is rather old, but I can't find that bios version on https://www.msi.com/Motherboard/B360M-B … pport#bios
What brand & model is this system ?

seth · 2022-07-12 17:21:18

The board might simply disable the IGP when you add a GPU.

https://forums.developer.nvidia.com/t/4 … ion/181876
https://forums.developer.nvidia.com/t/s … 060/170876

That user runs into an nvidiaUnlock abort because i195 didn't support their IGP an they ended up w/ the fbdev driver.
But keep in mind that for borrate, this is also a race condition - once settled, everything's fine.

@borrate, is this also an issue on warm reboots?
What if you slow down the boot by passing "boot_delay=50" to the kernel?

borrate · 2022-07-13 19:45:59

@Lone_Wolf
lspci -k from arch install iso
I think is the original BIOS and that is why is not listed for download. I'll never thought of updating it, I'll try this weekend.

@seth
It happens on warm reboots too, but inconsistently, sometimes it does not crashes.
I tried a couple of times with boot_delay=50 and it got stuck on motherboard splash screen, waited a couple of minutes and rebooted manually, I'll try again with a smaller number just to see if I can boot correctly.
