[WORKAROUND] Old SiS video card - black screen when using X

[marja]

Since I installed x11-driver-video-sis-0.10.7-2.mga3 , I get a black screen when trying to do a graphical login, or when being in safemode or RL3 and trying to start a DM, or Xorg, or just doing startx.

(The update became available on the 13th of September, I installed it on the 15th)

Does anyone else have this problem, too?

Do you have a(n old) SiS video card too, but X works fine with x11-driver-video-sis-0.10.7-2.mga3 or x11-driver-video-sis-0.10.7-3.mga3 ?

Please tell me

Thanks,
marja

Finally found the upstream bug report for this issue:
https://bugs.freedesktop.org/show_bug.cgi?id=35763#c2

Adding

Code: Select all

Option "noAccel" "true"

to the section "Device" of /etc.X11/xorg.conf
is a good workaround. My SiS driver works again, and if not perfect, it is still lots better than using the vesa driver.

My Device section in xorg.conf now looks like this (only the last Option was added):

Code: Select all

Section "Device"
    Identifier "device1"
    VendorName "Silicon Integrated Systems [SiS]"
    BoardName "SiS old series-based cards"
    Driver "sis"
    Option "DPMS"
    Option "SWCursor"
    Option "NoAccel" "true"
