[SOLVED] Using older nouveau or nvidia driver on new kernel

slug001 · 2024-12-16 22:46:36

it's not a problem with x though. as soon as i boot, i get a black screen. it happens on live usb drives, different distros... i had to go in with nomodeset to even install arch

See whether you can reproduce this an preserve a journal (either ssh into the blind system or reboot by frenetically pressing ctrl+alt+del or using the https://wiki.archlinux.org/title/Keyboa … el_(SysRq) ) so we can see what's going on.

Are non-wxwidget clients affected by the insufficient EGL version a well (eg. gtk3-demo)?

slug001 · 2024-12-17 19:07:10

gtk3-demo works fine.

[main@archlinux ~]$ ldd /usr/lib/libwx_gtk3u_gl-3.2.so | grep -i egl
	libEGL.so.1 => /usr/lib/nvidia/libEGL.so.1 (0x00007df8d9600000)
	libwayland-egl.so.1 => /usr/lib/libwayland-egl.so.1 (0x00007df8dac01000)

[main@archlinux ~]$  readelf -sW /usr/lib/libEGL.so.1 | grep eglCreatePlatformWindowSurface
    92: 0000000000008460   109 FUNC    GLOBAL DEFAULT   10 eglCreatePlatformWindowSurface

[main@archlinux ~]$ pacman -Qo /usr/lib/libEGL.so.1
/usr/lib/libEGL.so.1 is owned by libglvnd 1.7.0-1

i can get you the journal, i'll send it over when i'll be near a vga monitor how should i blacklist the nvidia driver correctly though?

This is the problem:

libEGL.so.1 => /usr/lib/nvidia/libEGL.so.1 (0x00007df8d9600000)

readelf -sW /usr/lib/nvidia/libEGL.so.1 | grep eglCreatePlatformWindowSurface

But don't try to just replace the library - that will probably make things worse.

Does explicitly selecting the X11 backend help?

GDK_BACKEND=x11 kicad

slug001 · 2024-12-17 20:52:23

yep, it's not in the nvidia library. the backend set didn't help :c

seth · 2024-12-17 21:09:45

What happens for

LD_PRELOAD=/usr/lib/libEGL.so.1 kicad

?

slug001 · 2024-12-17 21:56:41

woah it works!! thank you angel ^^, anything i can do so i can open it from the de? exporting it system-wide sounds like a bad idea
also i fixed the gtk thing by exporting GDK_DISABLE=egl. some stuff is definitely broken (the icons in gnome-control-center are very low res for some reason), but it works which is nice
i'll start the nouveau investigation soon, maybe i'll switch if it starts working and the performance doesn't decrease much

exporting it system-wide sounds like a bad idea

Very bad idea - you'll have to be careful, it might run kicad into unexpected issues if it ends up actually using egl ("GDK_DISABLE=egl" alone doesn't work?)

/usr/local/bin/kicad

#!/bin/sh
export LD_PRELOAD=/usr/lib/libEGL.so.1
exec /usr/bin/kicad "$@"

slug001 · 2024-12-17 23:28:16

nope, doesn't work without the linker thingy
the script doesn't change anything i think? edit: nvm had to make it executable

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
