I've tried to come up with a test that would hang/crash the xserver reliably, but failed. It usually takes a number of cycles through mirrored/extended/external-only modes, or switching between external-only and mirrored. Anyway, the impact is that on intel+nvidia hybrid the server can crash or hang or just fail to set the mode without these two patches. -- t _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
