--- Comment #13 from Martin Schmidt ---
Dear all, back to some minor extend ...
with xf86-video-nouveau installed:
- booting (advanced options for 15.6) with kernel 5.14 works well on the first
screen and ends up in the desired 2-screen environment.
- booting (advanced options for 15.6) with kernel 6.4 switches to the second
screen after "loading intial ramdisk". The first screen goes to sleep forever.
The login screen is blured, but password input works anyway - just guessing
where to type. Then a normal 1-screen kde comes up.
I had deinstalled xf86-video-nouveau. Doing so I did not get a login screen at
all, when booting kernel 6.4. The system was accessable remotely via ssh, so I
reinstalled this module with zypper this way.
Deinstalling also Mesa-dri-nouveau makes the system almost irresponsive, some
fallback using a small graphics device in the memory seems to do a very slow
job. I reinstalled this module.
modeprobe -D nouveau
shows different results for both kernels.
insmod
/lib/modules/5.14.21-150500.55.59-default/kernel/drivers/video/fbdev/core/fb_sys_fops.ko.zst
insmod
/lib/modules/5.14.21-150500.55.59-default/kernel/drivers/video/fbdev/core/sysimgblt.ko.zst
insmod
/lib/modules/5.14.21-150500.55.59-default/kernel/drivers/video/fbdev/core/sysfillrect.ko.zst
insmod
/lib/modules/5.14.21-150500.55.59-default/kernel/drivers/video/fbdev/core/syscopyarea.ko.zst
is missing with 6.4. Also
insmod
/lib/modules/5.14.21-150500.55.59-default/kernel/drivers/gpu/drm/drm.ko.zst
does not have a 6.4-counterpart.
I am producing the dmesg - logs now and will upload them soon.
Cheers
