Well, there are really two cases to consider: 1. BIOS/whatever configures display hardware rotation in a way that matches the orientation of the physical display 2. BIOS didn't do that. Either the hardware can't do what would be required, or the BIOS just chose not to do it. Case 1 should work with these patches as long as the DDX will set up the initial randr rotation to match what it read out from the kms rotation property of the primary plane. Case 2 can't work without some mechanism to query the orientation of the display from the firmware/etc. -- Ville Syrjälä Intel OTC _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
