Description Piter PUNK 2005-07-29 02:38:08 UTC 
Hi,

I am running X11R6-6.8.1 in a 598MLR motherboard, with on-board AGP video
(SiS520), i put one Trident 975Imàge in PCI slot and try to use Xinerama.
But a few things happens:

1. In first time, all got ok, only a little flickering in screen.
2. If i Ctrl+Alt+BS, and start X again, the SiS video works OK, but the
   Trident video looses the correct frequency and i lose the image (sometimes
   the screen goes to 800x600 instead 1280x1024).
3. If i Crtl+Alt+BS again, and start X again, both screens loose their video.
   Ctrl+Alt+BS don't works (ok, it works, but i don't got console back!).

This things all happens in 16bit mode. In 24bit mode, the Trident screen
got very confused and flickering. I try many times, only one time i got an
real "error" message talking about vm86 error on trident module.

If i put the primarly display on PCI and second on AGP, the system goes to
3. in the first time. If i disable vesa framebuffer, the things are more
stable but the 1. flickering continues.

Any improvements using the 7.1 xorg release?

Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state.
