Hello,

Recently, I’ve been experiencing high CPU usage when playing videos. It turns out there was an issue with hardware acceleration with integrated graphics. I have dual channel RAM. On my journalctl, it says something like

Crash Annotation GraphicsCriticalError: |[0][GFX1-]: glxtest: ManageChildProcess failed
 (t=0.453402) [GFX1-]: glxtest: ManageChildProcess failed
Crash Annotation GraphicsCriticalError: |[0][GFX1-]: glxtest: ManageChildProcess failed
 (t=0.453402) |[1][GFX1-]: No GPUs detected via PCI
 (t=0.453402) [GFX1-]: No GPUs detected via PCI

Using lspci, the iGPU is detected

LibreWolf/Firefox tells me that hardware acceleration is disabled.

I have tried setting gfx.webrender.all to true but to no success. Inxi works

However, with X11, these issues do not exist.

If there is a fix coming soon, please let me know!

Yea, that’s why we don’t use Wayland. It was always unpredictable - wasn’t worth using it, for our machines.

I was thinking that it’s worth because of security and performance.

And also, I think X11 doesn’t run well with multiple monitors sadly…which is a pain.

Admittedly, no multiple monitors here - only have the one 38 inch Dell curved monitor - waaaay more than enough screen. Don’t (or will ever?) use Wayland.

Damn…that’s crazy.

I am using dual monitors, different size and it works perfectly well under X11.

I have noticed after a fresh install dual monitor is broken and I need to disable one of the monitors and then install nvidia driver for my video card before it all starts to work well.

Last time I used it, I wasn’t able to set individual scaling properties and I couldn’t turn off my laptop screen.

Update: So I decided to run LibreWolf/Firefox under XWayland and it works. I believe this has to do with LibreWolf/Firefox itself where hardware acceleration is broken on Wayland as it prints out GLXTest errors everywhere.

Really wanted to run it under Wayland since it’s better on the battery.
