Comment # 9 on bug 952781 from Max Staudt

Felix, thanks a lot for taking the time to test this, and in general making
sure that openSUSE runs well even on older hardware. I'm an enthusiast of those
things myself, and really appreciate your help. This is part of what keeps the
Linux community thriving in the way it does.

Unfortunately, I am unable to find a SiS graphics card of any but the oldest
generation, so I am unable to replicate and debug your setup with an XGI card
or any other card of that generation.

What's more - going forward, User Mode Setting drivers such as xf86-video-sis
will stop working in future releases, as we transition into an environment
where the X server is no longer allowed to poke the memory directly. This is
already the case on UEFI Secure Boot systems, as well as on current Tumbleweed
when logging in via gdm (it launches the X server as a non-root process).

Seeing as according to "man sis", the Z7 support (which is probably spotty, see
Comment 7) does not have XVideo acceleration anyway, may I suggest looking at
the Linux kernel's "sis" fbdev driver? It looks very complete, so combining it
with xf86-video-fbdev probably makes a good team. This should also future-proof
your setup.
