It looks like I also need to do 'xset s 0' because X also crashes if the screensaver comes on for more than a few seconds. Screen Saver: prefer blanking: yesallow exposures: yes timeout: 0cycle: 600 Maybe it has something to do with turning off the backlight? - Grant ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx

BTW, this does not prevent the problem: DPMS (Energy Star): Standby: 0Suspend: 0Off: 0 DPMS is Enabled Monitor is On It has to be this: DPMS (Energy Star): Standby: 0Suspend: 0Off: 0 DPMS is Disabled I've tried different kernel versions as well as different versions of xf86-video-intel and xorg-server with the same result. - Grant ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
[Intel-gfx] black screen if sna & TearFree
I'm using a Dell XPS 13 laptop on Gentoo and if I use: Option "AccelMethod" "sna" Option "TearFree" "true" my video tearing problem disappears, but if I close my laptop lid for a few minutes, it comes back up with a black screen, although I can get my session back if I switch to VT1 and then back to VT7. I can't find anything in the logs. I've tried xf86-video-intel-2.20.3 as well as the latest from git. The problem doesn't occur without the above two directives. Does anyone know how to diagnose or fix this? - Grant ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
