Poor video performance on core i9 185H

User Support Hardware Issues

I remember super snappy GUI on 11th gen i7, and now it just sucks! Mouse movement is jerky and everything seems off performance-wise. I tried removing cores 20 and 21 and assigning them to network and firewall qubes, it apparently improved the situation but not much. Either video driver sucks or something else is wrong.

You can use the XFCE Task Manager to see the idle CPU usage, it could tell you if xorg is using the CPU. I have had a system that didn’t default to the correct xorg driver, it made xorg idle at ~15% when it should be close to 1%.

Check the xorg logs, to see if there is something that doesn’t load correctly.

I always generate a new xorg.conf with X :1 -configure, and make xorg use that config file, just so I can see exactly what is happening. The correct way to do this would be to add changes to xorg.conf.d, I’m just too lazy and xorg will read xorg.conf from /etc/X11

That’s a xorg.conf that makes miracle on my 12th gen intel 1245u

Section "Module"
      Load   'glamoregl"
EndSection
Section "Device"
      Identifier   "Intel Graphics"
      Driver   "modesetting"
EndSection

This is exactly what X11 “auto-detects” on my 12th gen: cat /var/X11/Xorg.0.log | less. Everything ist there. modesetting driver, Iris DRI, GL, etc. The only config, that’s needed is keyboard.

It didn’t detected it for me. Auto detect made me xorg.conf with intel driver and "DRI" "3" option.
Was forced to find it at arch wiki.

However, it says it Refusing to try glamor on llvmpipe glamor initialization failed.

Could it be the issue?

I still think something is wrong. glamor should work, right? And if it does not, the video performance is quite mediocre.

Could you share your xorg.log ? It seems that something is not right on my computer. When I just grab a window with mouse and move it around xorg can eat up to 40-50% cpu which is definitely not normal.

Enable the window compositor in XFCE, this will render the display of windows using the GPU, which is a lot more effective than using the CPU.

To enable Xfce compositing, go in Settings Manager (xfce4-settings-manager) > Window Manager Tweaks > Compositor > Enable display compositing

(from [Solved] Compositing / Desktop / Xfce Forums)

Note that this has nothing to do with the actual GPU rendering of the content of the windows in a qube. (just making sure nobody thinks this magically solves the GPU rendering problems from qubes…)

Already enabled :frowning: Seems that GPU gets undetected somehow and everything is done in software.

It’s maybe too new for the Fedora used in dom0

damn. should I wait for an update or are there some tweaks? I have no idea why suddenly it is non-accelerated but that sucks! I hate this computer and old drivers :confused: Tried force_probe the i915, did not help either :confused:
