I'm having problems with getting a sis 771/671 PCIE VGA display adapter to play
nice with Arch on my asus X5DC laptop.


[marshall@jynx ~]$ lspci | grep VGA 01:00.0 VGA compatible controller: Silicon
Integrated Systems [SiS] 771/671 PCIE VGA Display Adapter (rev 10)





I've tried drivers from extra (extra/xf86-video-sisimedia 0.9.1-3) and AUR
(aur/xf86-video-sis671 0.10.3-1). Both drivers give the same results, a bright
dark-grey screen getting lighter towards the middle, with the middle being
almost white. I am then returned to a prompt with Xorg saying No screens found.
Looking through /var/log/Xorg.0.log it looks like xorg did find a screen and
tried EVERY possible resolution to start an Xsession but couldn't find a
suitable one.



My questions are:

Is this the right driver for the card or should I be trying something else.

Has anyone got the same card working with this driver and an xorg.conf?



I'm running the VESA driver ATM, which is working fine until I try to play full
screen video or play mari0, then things get slow and ugly.

Any help would be appreciated.


Regards

According to the wiki [1], there is another driver xf86-video-sis which
might work better. But of course you shouldn't have installed three
drivers all together.


I hope I could help you.

Thank you very much for the pointers Nelson.
