But you shouldn't rename/symlink the drivers, as that's a source for
major confusion. Please revert.
Done, thanks for the explanation.
You might try a minimal xorg.conf (or xorg.conf.d/*.conf snippet)
containing only
Section "Device"
Identifier "My GPU"
Driver "nvidia"
EndSection
to specifically select the proprietary driver and skip autoprobing.
Should help to avoid irrelevant error messages from autoprobed drivers.
Ok this way it loads properly, the nvidia logo is displayed and X starts
fine when loading only xterm.
Any idea why this xorg.conf is required now while it used to be
autodetected? Is this related to
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1099016#40 ?
However
- running plasmashell leads to a crash with the nvidia driver. Same for
kwin. There is no crash with "nouveau" though.
- running gnome-session works fine and Gnome shows up without issue with
the nvidia driver.
gdm3 is displayed properly as well, while sddm is not.
plasmashell writes this output:
qt.glx: qglx_findConfig: Failed to finding matching FBConfig for
QSurfaceFormat(version 2.0, options
QFlags<QSurfaceFormat::FormatOption>(ResetNotification), depthBufferSize

alphaBufferSize -1, stencilBufferSize -1, samples -1, swapBehavior
QSurfaceFormat::SingleBuffer, swapInterval 1, colorSpace QColorSpace(),
profile QSurfaceFormat::NoProfile)
Could not initialize GLX
Aborted (core dumped)
for kwin it is the same, except with swapInterval "0" instead of "1".
I could launch KDE/Plasma with any of:
export QT_XCB_GL_INTEGRATION=xcb_egl
export QT_XCB_GL_INTEGRATION=none
But graphics are not polished.
KDE/Plasma doesn't work when QT_XCB_GL_INTEGRATION is not set or has:
export QT_XCB_GL_INTEGRATION=xcb_glx
I tried these different values in .config/plasma-workspace/env/xcb.sh
Do you think a rebuild of the nvidia/Opengl driver would fix the issue?
Or is Kde/Plasma requiring features not provided by the nvidia driver?
But it may well be that the driver is no longer compatible with current
Xorg versions.
It seems to work actually, at least partially. :)
