On the next reboot my monitor went dark and into "power-saving mode" when drm started at boot. The screen remains on until that moment, so i still have vision of all the debug output the kernel throws at bootup before drm starts. The same setup worked on slackware64-current with the 2.6.33 kernel. Hardware used: A monitor connected to DVI. Physical setup didn't change. Monitor information from Xorg.0.log: (II) intel(0): EDID vendor "GSM", prod id 22136 (II) intel(0): Using EDID range info for horizontal sync (II) intel(0): Using EDID range info for vertical refresh (II) intel(0): Printing DDC gathered Modelines: (II) intel(0): Modeline "1680x1050"x0.0 119.00 1680 1728 1760 1840 1050 1053 1059 1080 +hsync -vsync (64.7 kHz) ... some more modelines ...

Tested setups that were broken: - Distro: Slackware64-current - Xorg 1.7 - Kernel 2.6.35-7 (from distro) - Distro: Slackware64-current - Xorg 1.7 - Kernel 2.6.36-rc8 (custom compile) - Distro: Ubuntu Linux (x64) - Xorg 1.9 - Kernel 2.6.35-7 (from distro) In all the broken setups the dvi-connected display switches off just after drm is loaded at bootup. VGA works fine. xrandr -q tells me the dvi display is not connected. Thanks in advance,
