Slow external display performance when laptop display disabled

Btw, thanks for helping me!
It is fun learning and working with you

Those are the glxgear output with compositor disabled/killed:

glxgears                    
10854 frames in 5.0 seconds = 2170.730 FPS
10959 frames in 5.0 seconds = 2191.755 FPS
10952 frames in 5.0 seconds = 2189.368 FPS
9234 frames in 5.0 seconds = 1846.583 FPS
X connection to :0 broken (explicit kill or server shutdown).

prime-run glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
974 frames in 5.7 seconds = 169.469 FPS
5 frames in 5.0 seconds =  1.000 FPS
6 frames in 6.0 seconds =  1.001 FPS
X connection to :0 broken (explicit kill or server shutdown).

export __GL_SYNC_TO_VBLANK=0
prime-run glxgears          
13154 frames in 5.0 seconds = 2630.751 FPS
10892 frames in 5.0 seconds = 2178.345 FPS
11768 frames in 5.0 seconds = 2353.595 FPS
X connection to :0 broken (explicit kill or server shutdown).

intel only is a lot faster without compositor.
prime-run is still crippled
export + prime-run is a low faster without compositor.

I also can't figure out why Firefox is now crippled without DRI_PRIME=1

Firefox --refresh didn't help
Creating a new empty profile didn't help
Running firefox --safe-mode fixes the issue though.

It seems firefox --safe-mode disables:
- HW acceleration
- WEB GL

I tried doing that manually but whenever I run without --safe-mode then firefox is again crippled.

Some console outputs:

firefox in safe mode:

firefox without safe mode (on an refreshed profile without extensions and so on):

Okay, I seem to have fixed firefox but I am not sure why this fix is working.

Settings -> Performance -> Use recommended performance setting (disable) -> Use hardware acceleration when available (disable)

If both are disabled, firefox is back to normal and the error "ATTENTION: default value of option mesa_glthread overridden by environment." is only outputted once in the terminal (instead of 4 times) when starting firefox.

Interestingly, the following options are still enabled in about:config:
media.ffmped.vaapi.enabled
And about:support still shows "WebRender (Software)" as "Compositing

So now I am back to my previous problem with slow external displays.
I just thought this firefox issue might help finding the cause of the original problem.

seth · 2023-01-05 15:12:38

Because you're now using software GL w/ FF.
There's especially no vsync in software GL - this isn't really a fix.

Make sure to export "export __GL_SYNC_TO_VBLANK=0" to the session.
As for intel being slow w/ the compositor enabled, look at the compositor settings - kwin does not seem to sync (glxgears run in #25) but things like the blur effect or color correction might be too much for the IGP to provide > 120fps

Utini · 2023-01-06 17:16:08

I found another option regarding vsync to disable it. I use both for now:

export __GL_SYNC_TO_VBLANK=0
export vblank_mode=0

But isn't is weird that my iGPU gets higher frame rates with glxgears than my NVIDIA GPU?

glxgears

42399 frames in 5.0 seconds = 8479.672 FPS

I didn't have many options activated in the compositor / windows effects.
I have now disabled pretty much everything (but that was jut 2-3 options more) and will give it a try when I am back in the office (don't have so many screens at home to test ).

Something I notice one my internal (laptop display) though:
When moving windows, I get tearings. As in the text of those windows looking weird.

No. glxgears isn't a beenchmark. It's not very challenging to any graphics hardware and copying over the buffer from the nvidia to the intel chip becomes the limiting factor.

I get tearings. As in the text of those windows looking weird.

"tearing" describes an artifact where parts of two different frames are passed to the output - it's the default unless you take couter measures like syncing the buffer updates to the outputs vblank signal (vsync…)
It doesn't however make the "text look weird" - do you have a screenshot or photo of that effect?

With weird looking text I meant tearing. Basically the text line will look "weird" or ripped. Could only show it by doing a video of it.

I could try enabling vsync when not connected to external displays and disable vsync when connecting a display. But first I need to test if that will even fix the solution. I kinda doubt it and I also doubt that the HD630 is too weak to drive 2x FHD display. But I will test it on monday

Utini · 2023-01-09 06:32:17

Okay, I did some testing and got even more problems. But lets start step by step.

KWIN has an option under "Desktop Effects" to Show FPS on the desktop. I enabled this, vsync disabled, compositor enabled:

1x external display: 120-180fps
2x external display: 40-60 fps
2x external display + internal display: 20-30 fps
Only internal display: 60fps

Since I can't believe that the iGPU is too weak to drive 2 external displays I rebooted into dual-boot Windows 10 to check the performance there.
While I didn't check for the fps, I noticed that everything was very very fluid with all 3 displays enabled.
I noticed how ever, that the nvidia-optimus logo was active and saw that it said "2 applications running on NVIDIA GPU".
The 2 applications were the both external displays.

So it seems that on windows, both external displays will be powered by the nvidia GPU.
Maybe this has to be the same for Arch to get good performance?
@edit: I found this but that doesn't work for me:

Additionally I had the following problems (not sure if this related and helps resolving the main issue):
I rebooted from Windows back to Arch.
The FPS display was still active.
Before I could even disable it, the whole system froze.
I had to force power off on my laptop and rebooted.
Now all KDE desktop settings were gone (no task bar, no widgets, no backround, no anything).
One of the external displays (the main one) was basically just black but I could saw my cursor moving on it.
Spawning a windows on it would only create half of the windows (e.g. only the borders or the window without border) and freeze the whole system again.
This would happen over and over and over.
So I had to disconnect all displays, boot on the internal display only, re-connect my displays and now it seems to be stable again.
All desktop settings are still gone though. So I have to re-configure wallpaper, taskbar, etc.

Online I read about a KDE bug where an external display would sometimes turn up completely black and becomes unconfigurable.
The fix is supposed to be "kquitapp5 plasmashell && kstart5 plasmashell".
In the past few days this really helped, and I did it today too but my taskbars where still resetted.
However, my wallpaper settings were atleast back.

This is the output of the above command, with several errors:

kquitapp5 plasmashell && kstart5 plasmashell

I seem to have two configuration files for xorg:

/etc/xorg.conf:

Section "Device"
       Identifier  "Card1"
       Driver      "modesetting"
       BusID       "PCI:0:2:0"
EndSection


Section "ServerFlags"
    Option "DontZap"      "True"
EndSection

Section "ServerFlags"
    Option "DontVTSwitch" "True"
EndSection

/etc/X11/xorg.conf:

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "intel"
    Inactive "nvidia"
    Option "AllowNVIDIAGPUScreens"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
    Option "AllowEmptyInitialConfiguration"
    Option "NVreg_DynamicPowerManagement=0x02"
    Option "Coolbits" "1"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    BusID "PCI:0:2:0"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

I guess I can (and should?) delete /etc/xorg.conf?

And here are some journalctl from crashes that just happend.
The first log was made after a crash.
I rebooted arch and all my KDE desktop settings were resetted again.
One display (secondary screen) had a taskbar.
Main display didn't have one.
As soon as I spawned a window on the main display - crash.

journalctl -b -1
Link: https://pastebin.com/Wivx59Ze

journalctl --since=today
Link: https://files.bestmail.ws/Arch/crash2.log

@edit:
This system is getting unusable with 2 screens now. It's basically freezing/crashing every 10 mins randomly :S

This is all with compositor disabled/killed.

@edit2: Three hours later, with compositor enabled, it seems more stable now (no freeze/crash). But ofcourse laggy as hell.
@edit3: Or not, here is another crash with compositor enabled this time: https://pastebin.com/APrLDKtr
Basically this happens everytime I boot with both external displays connected and then open a new windows (konsole,dolphin, whatever).
If I boot without them connected, and then connect them after booting, everything is fine.
@edit4: Another freeze/crash. It seems like KDE is freezing but everything else works because I was still able to write in my active RDP Session lol
Link: https://pastebin.com/kwxC9M46

Not sure if this is relevant. I have:

/etc/udev/rules.d/80-nvidia-pm.rules

# Enable runtime PM for NVIDIA VGA/3D controller devices on driver bind
ACTION=="bind", SUBSYSTEM=="pci", ATTR{vendor}=="0x10de", ATTR{class}=="0x030000", TEST=="power/control", ATTR{power/control}="auto"

nvidia-smi shows that some sort of xorg is running on the dgpu though?

Is there a way to verify reverse-prime is working? The wiki doesn't have an entry to verify that.

Becuase then I could connect a display directly via HDMI (instead of using the USB C dock) to verify if that changes anything?

V1del · 2023-01-10 10:50:01

As per the post I linked in #16 (... and e.g.: https://bbs.archlinux.org/viewtopic.php?id=282161 ) have you already tried downgrading the nvidia driver to a 520 variant? AFAIK this is a known regression in 525 in this constellation

As for verification, the xorg log should show the settings that are applied, generally "some sort of Xorg process" is normal and expected

Hi V1del, thanks for the hint but it didn't help.
I am now on "520.56.06" and still have the issue (I downgraded nvidia-dkms, nvidia-utils).

Some additional infos I figured out:
nvidia settings shows the displays connected to the dgpu
See those 3 screenshots: https://imgur.com/a/CF37Ivo

nvidia-smi shows some GPU utilization (and even xorg is listed there)

It is fixed... thanks to a "Commander" on the Archlinux Discord server.
This was missing in my configuration: https://us.download.nvidia.com/XFree86/ … ndr14.html

How ever, this means that xorg will now still run on the dGPU if no external display is connected.
Meaning my dGPU will never go into battery saving mode on my laptop?

Should I now remove any of the previous steps that I took during this troubleshooting?
E.g.
Upgrade nvidia to latest version
Remove KWIN_X11_NO_SYNC_TO_VBLANK=1
Remove export __GL_SYNC_TO_VBLANK=0
Remove .drirc

Yes, if I'm interpreting this correctly you are now simply using the old method and thus the nvidia gpu does everything and the intel GPU is just a dumb pipe not doing much actual work.

This should become apparent if you check nvidia-smi now as everything that use graphics should default to the nvidia GPU and you're likely to see kwin and plasma on there as well as Xorg.

you can try and check behaviour by reverting your steps so far yes. FWIW regarding your duplicated xorg.conf question, on a normal setup /etc/xorg.conf will simply never be read so the file is likely to not do anything.

1x external display: 120-180fps
2x external display: 40-60 fps
2x external display + internal display: 20-30 fps
Only internal display: 60fps

As for intel being slow w/ the compositor enabled, look at the compositor settings - kwin does not seem to sync (glxgears run in #25) but things like the blur effect or color correction might be too much for the IGP to provide > 120fps

Though the above along

Clone setup: Now I know what you mean, I tried that already but it didn't work. I now used your three commands to create a clone setup again. How ever, the performance is still as bad.

suggests there're some syncing issues (so that't not be effectively disabled), maybe the kwin MaxFPS being capped.

qdbus org.kde.KWin /KWin supportInformation

I rebooted into dual-boot Windows 10 to check the performance there.

3rd link below. Click it. Mandatory.

I noticed however, that the nvidia-optimus logo was active and saw that it said "2 applications running on NVIDIA GPU".
The 2 applications were the both external displays.

This is necessary when/if the external outputs are attached there and the reason why Xorg shows up in nvidia-smi.

Huh, which 3rd link below do you mean?
@edit: oh you mean disable fast startup and hibernation.
I did that already previously. Thanks!

The only differences according to meld:

glStrictBinding: true (iGPU), false (dGPU)
glPreferBufferSwap: 101 (iGPU), 99 (dGPU)
Direct rendering: Requires strict binding: yes (iGPU), no (dGPU)
.. the refresh rate of Name: DP-1-0 and DP-0 (both same external screen) differes as well on one screen (75Hz vs 60Hz) but that is because I changed it manually to 60Hz now.

Also there is something generally wrong when not using the dGPU as main GPU because the whole system freezes and goes to 100% CPU usage by KWIN when connecting/disconnecting the external screen.
I have to force/hardware reboot the laptop and plugin the displays after X loaded.

I tried "prime-run kwin_x11 --replace" to see if performance increases when KWIN runs via dGPU, but that crashes the system.

Yes, if I'm interpreting this correctly you are now simply using the old method and thus the nvidia gpu does everything and the intel GPU is just a dumb pipe not doing much actual work.
This should become apparent if you check nvidia-smi now as everything that use graphics should default to the nvidia GPU and you're likely to see kwin and plasma on there as well as Xorg.
you can try and check behaviour by reverting your steps so far yes. FWIW regarding your duplicated xorg.conf question, on a normal setup /etc/xorg.conf will simply never be read so the file is likely to not do anything.

I removed /etc/xorg.conf.. laptop is not burning so far
And yes, nvidia-smi now lists all kind of applications.
Not what I want on my laptop.
I would rather have the iGPU as main GPU and then run relevant apps via prime.
I would also be okay with restarting/running specific apps automatically via prime when an external display connects (e.g. KWIN or so) if that helps.

I made a temporary work around although I believe I could simply use optimus-manager for that as well.

/home/user/bin/udev/dgpu-external-display.sh:

#! /usr/bin/bash
function connect(){
  mv /etc/X11/xorg.conf.d/10-gpu.conf.bak /etc/X11/xorg.conf.d/10-gpu.conf
}

function disconnect(){
  mv /etc/X11/xorg.conf.d/10-gpu.conf /etc/X11/xorg.conf.d/10-gpu.conf.bak
}

if [ $(cat /sys/class/drm/card1-DP-1/status) == "connected" ] ; then
  connect
elif [ $(cat /sys/class/drm/card1-DP-2/status) == "connected" ] ; then
  connect
elif [ $(cat /sys/class/drm/card1-DP-3/status) == "connected" ] ; then
  connect  
else 
  disconnect
  exit
fi

sudo nano /etc/systemd/system/dgpu-external-display.service

[Unit]
Description=Check if  external display is connected and enable/disable dGPU accordingly
[Service]
Type=oneshot
ExecStart=/home/user/bin/udev/dgpu-external-display.sh
[Install]
WantedBy=multi-user.target

/etc/udev/rules.d/95-hdmi-plug.rules:

ACTION=="change", SUBSYSTEM=="drm", ENV{DISPLAY}=":0", ENV{XAUTHORITY}="/home/user/.Xauthority", RUN+="/home/user/bin/udev/dgpu-external-display.sh"

/usr/share/sddm/scripts/Xsetup:

/home/user/bin/udev/dgpu-external-display.sh

This will enable/disable the dGPU as main GPU for outputs depending on if something is connected as external display or not during session and when booting the device.
I left out the HDMI Port on purpose because this is the usual port I would use when doing presentations (=I need my battery).

It sill required a login/logout which is annoying. Especially when having 4 meetings a day and constantly swap between office/meeting.

I believe getting a new laptop with AMD+AMD GPU won't be of any help either since this uses prime as well?

The only option would be to ditch a dGPU completely and only have an iGPU?
Which is sadly not really an option for me.

V1del · 2023-01-13 09:11:31

There are laptops (... my Acer V15 somethingsomething) where the dGPU is just for accelerated application purposes and all screens are attached to the integrated GPU avoiding a large host of issues.

But I don't think you can really generalize this in that way, afaik the 1 FPS issue while using PRIME the "normal" way - while a bug - is not technically unsolvable and it isn't clear whether an amdgpu combination would have the same issues (no hands on here)

Ah ye right, there are systems where the connection between those two GPUs is different (e.g. muxless(?)).

I believe I do not suffer from the "1 FPS" issue? I get 30-40fps (according to KWIN widget).

V1del · 2023-01-13 09:58:55

Ah whoops missed that, just generally slowish? FWIW because looking at the post again, are you able to reproduce this on a normal non hardened kernel and without most of these i915/iommu parameters?

While researching this problem I saw that you recommended this a few months ago to someone on reddit as well ;-)

So I did that and installed linux and linux-headers
NVIDIA is still the same "old 520" package.

GRUB Kernel Parameters:

cryptdevice=/dev/nvme1n1p3:luks:allow-discards rd.luks.options=discard nvidia_drm.modeset=1 nmi_watchdog=0 psmouse.synaptics_intertouch=1

glxgears:

glxgears  
872 frames in 5.0 seconds = 173.842 FPS
935 frames in 5.0 seconds = 185.448 FPS

prime-run glxgears
1880 frames in 5.0 seconds = 374.184 FPS
2173 frames in 5.0 seconds = 434.403 FPS

I am still having the same issue:
Slowish, laggy desktop as soon as KWIN is enabled.
If I kill KWIN compositor, then everything is fine.
Small video demonstrating (recorded with 60fps on my Pixel 6 Pro): https://files.bestmail.ws/nvidialag.mp4
Additionally KWIN again froze the whole system and used 100% CPU when creating a first GUI-Windows because I booted with external displays connected.

Also:
I have both installed "intel-media-driver" and "libva-intel-driver" but I guess I only need one for HW Acceleration on my i7-8850H? Which one? :S

Additionally I just did some power measurements with powerstat.

With dGPU as main GPU: 10,8W idle drain
With iGPU as main GPU: 10,8W idle drain

Why even bother using hybrid mode lol?

dGPU as main GPU means: /etc/X11/xorg.conf.d/10-gpu.conf
