Working driver for VGA Controller P4M890

wishmasterf · September 4, 2018, 12:20pm

Hello,

First of all:

OS: latest Tumbleweed
**VGA Controller: **01:00.0 VGA compatible controller: VIA Technologies, Inc. P4M890 [S3 UniChrome Pro] (rev 02)
Kernel: Linux linux-8839 4.18.5-1-default #1 SMP PREEMPT Fri Aug 24 12:38:43 UTC 2018 (9e91e29) x86_64 x86_64 x86_64 GNU/Linux

My problem is, that i do not get higher resolution than 640x480 in KDE. I tried openchrome and vesa. Openchrome gives me an error, vesa does not work with higher resolution. Attached you can find the Xorg-Logs.

vesa: https://uploadfiles.io/tqla2
openchrome: https://ufile.io/5yni5

I dont need 3D acceleration or something else special, only higher resolution.

Thanks for your help.

Thats how i fixed it.

I still had problems with sddm. read here: https://forums.opensuse.org/showthread.php/530860-sddm-not-starting

Installed openchrome.

zypper install xf86-video-**openchrome**

In /etc/defaul/grub i added following entries to prevent flickering:



GRUB_CMDLINE_LINUX_DEFAULT="splash=silent resume=/dev/disk/by-uuid/48233453-cf2b-480f-b3
0a-b30ae5585c2e quiet **video=vesafb:off vga=normal nomodeset**"

I created a new file /etc/X11/xorg.conf.d/10-moduls.conf with


Section "Module"
        Load    "shadow"
EndSection

and used openchrome as device in /etc/X11/xorg.conf.d/50-device.conf


Section "Device"
  Identifier "Default Device"
 Driver "openchrome"
EndSection
