Bug 60891

I've observed this segfault problem as well.
The SiS driver seems to be sadly under-maintained for one that is so widely, dare I say 'cheap and cheerfully' installed.  The high end, more powerful boards seem to attack the attention.  

I occasionally see boasts that Linux runs well on old equipment that Windows has bypassed.  Now I'm having to maintain some such old equipment I'm not sure its a valid boast.  Maybe it only applies to old version of Linux or _some_ version of Linux.

If fixing bug 35763 isn't possible, is it then possible to let the SiS video driver add

Option "NoAccel" "true"

to the SiS Device section in /etc/X11/xorg.conf ?

It would be great if at least that could be done :-D

If you're bold enough, here is my guide how to get back a fully accelerated X server on Fedora 18 by compiling an older version of X.org manually. Also works on CentOS 6.4 (tried myself few days ago).

WWell,

@ Assen

I'm not that bold ;)

Anyway, for Mageia this has been fixed thanks to this ArchLinux patch:

https://projects.archlinux.org/svntogit/packages.git/tree/trunk/0001-Disable-UploadToScreen-and-DownloadFromScreen.patch?h=packages/xf86-video-sis

I can nicely watch movies again :-D

This does not works for some cards. See

Sorry to hear that :-(

Do you mind listing here with which exact cards the patch works, and with which ones it doesn't

SiS 661FX is my card (going by the system's specifications, that is), with which the patch works. 

Does addin 

Option "NoAccel" "true"

to the SiS Device section in /etc/X11/xorg.conf

does adding that option help for the systems where the patch didn't work?

Option "NoAccel" unacceptable at all.
Computers with such cards are very old and have uses as X-terminals (LTSP). Performance with the option "NoAccel" so bad that these computers can not be used.
Please cooperate with https://bugs.freedesktop.org/show_bug.cgi?id=15190 - maybe it help solve this problem.

Sorry for my English.

I ran into the same problem with OpenBSD 5.7-beta, starting windowmaker crashed Xenocara.

the patch from Ubuntu, that can be found here:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-sis/+bug/1066464
and which is also mentioned in bug #35763 works for me.
