** Description changed: In my Samsung Q45 with Intel GM965 graphics I encounter the following problem when using KMS: After a suspend/resume cycle the internal LVDS always gets enabled, whether it was on before or not. State before suspend/resume: LVDS: off / VGA: 1600x1200 State after resuming from suspend: LVDS: 1280x800 / VGA: 1600x1200 "xrandr --query" reports that the LVDS is off and it is not possible to turn it off by issuing "xrandr --output LVDS --off" To finally turn the LVDS off it needs to be "enabled" it first by using "xrandr ... --auto". Afterwards it is possible to really turn it off. Expected behavior: - LVDS stays off after resume when it was off before Sidenote: If the displays are configured the other way round (VGA off/LVDS on) a suspend/resume cycle does not enable the VGA output. + + + + [lspci] + 00:00.0 Host bridge [0600]: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub [8086:2a00] (rev 03) + Subsystem: Samsung Electronics Co Ltd Device [144d:c510] + 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 03) + Subsystem: Samsung Electronics Co Ltd Device [144d:c510]
