hi
i love Opensuse!
i isntalled opensuse 42.3 with kde plasma 5 64bit, computer is old hardware.
in installation: i set “no KMS mode”. because hardware video is old: H3200 (AMD/ATI) but is bult in not card video, (on board)
installation is perfect nothing problem.
reboot there is:
grub2 (works)
booting (works)
systemd (works)
kde plasma (works)
opensuse is perfect working.
one problem is bad resolution: small solution (640x480 pixel)…
i go to see dmesg i find error:
[drm] VGACON disable radeon kernel modesetting.
[drm:radeon_init] ERROR No UMS support in radeon module!
i try see xorg.conf (/etc/X11/) there is not file but there is xorg.config.install…
so i try kubuntu CD-live 17.10
result:
booting (works)
systemd (works)
kde plasma 5 (works)
kubuntu (works)
but resolution is correct…
so i check /etc/X11/ there is not file xorg.config …
then i want to ask you :
i want opensuse 43.2 on old computer, but kubuntu how…?
how resolve this problem…?
There’s no need to use “no KMS mode” just because the hardware is old.
My Radeon card is much older (9600) and KMS works fine.
one problem is bad resolution: small solution (640x480 pixel)…
That’s because you disabled KMS (Kernel Mode Setting).
The radeon driver requires KMS though, so you are using some generic fallback now (fbdev).
That’s what the error message you posted tells you.
Go into YaST->System->Boot Loader and remove the “nomodeset” in “Optional Kernel Parameter”.
If in doubt, please post the whole line you have, either by taking it from YaST or running “cat /proc/cmdline”.
i try see xorg.conf (/etc/X11/) there is not file but there is xorg.config.install…
xorg.conf is not used since years.
Although it is still respected if it exists, but you should normally have no need to create it.
