And in addition to summary causes general havoc, including black screen internal screen, inability to do anything with blacked screen etc.
100% reproducible.

This is NV86 card running latest git versions of whole GPU stack (kernel/libdrm/ddx/xserver/mesa). Xserver is a bit outdated (a month old git or so, rest are pulled on almost daily basis, and compiled )

Verified to happen without compiz.
Also disabled pageflipping in DDX, although it won't be active without compiz anyway.

Comment 2 maximlevitsky 2011-10-09 06:16:35 UTC

OK, so it looks like PDISPLAY doesn't like us meddling with disabled crtc.
Thus the attached patch fixes the problem (it makes cursor restore to happen after modesetting).
