Problem STILL exists on 2.6.39. That any of the graphic > developers might be interested in the problem? I had a problem similar to this, beginning with 2.6.37 (2.6.36 was okay). It turned out to be that newer kernels were detecting the LVDS (LCD panel) interface from the chipset, event though nothing was attached to that interface. So GNOME would come up at 1024x768 (max the LVDS supported, I guess). I initially worked around it by going into the GNOME -> Preferences -> Monitors, and disabling the LVDS device there, in favour of the 1920x1200 "VGA" device I use. Later, I hacked my kernel to just ignore the LVDS completely: --- linux/drivers/gpu/drm/i915/intel_lvds.c.orig 2011-05-09 22:33:54.000000000 -0400 +++ linux/drivers/gpu/drm/i915/intel_lvds.c 2011-05-17 23:00:40.829773525 -0400 @@ -841,6 +841,7 @@ */ bool intel_lvds_init(struct drm_device *dev) { + if (0) { struct drm_i915_private *dev_priv = dev->dev_private; struct intel_lvds *intel_lvds; struct intel_encoder *intel_encoder; @@ -1041,5 +1042,6 @@ drm_encoder_cleanup(encoder); kfree(intel_lvds); kfree(intel_connector); + } return false; } ^ permalink raw reply [flat|nested] 5+ messages in thread
