Could you try xserver 1.5.3 to see if this is a regression from recent transform feature? Tested with latest git intel driver and xserver 1.5.3: it works! So please reassign to the component you think is the most appropriate. Keith, could you have a look of this? Does it work with xserver master? Please use same intel driver for test. We might add this to #17452 The panning additions to the X server broke some rotation/transform usage. I've pushed patches for this to the X server master, and will be pulling those to the 1.6 branch after a brief review. Testing X server master would be appreciated though, that should resolve this issue. Please test with xserver 1.5.99.903. This bug should be fixed. Reopen if you can still meet this. (Finally) tested with 1.5.99.903, and indeed, the rotation works :-) Unfortunately the performance on the rotated outputs is abysmal, somewhere around 1 fps when I scroll a page in firefox. It used to be fine... but maybe it's just because I now use UXA, and it's better with EXA, will try later. Ah, indeed, with EXA the performance is good also when rotated :-) Should I open a bug for UXA about this? |

I'm testing the beta versions and I'm having trouble with a dual screen setup when the VGA output is rotated. It used to work fine with intel 2.5.3 . Two screens non rotated works fine: xrandr --output LVDS --rotate normal --output VGA --preferred --right-of LVDS --rotate normal Rotation of LVDS works fine: xrandr --output LVDS --rotate left Rotation of VGA is accepted by the server but leads to a black VGA screen or VGA screen with some parts of the LVDS screen: xrandr --output LVDS --rotate normal --output VGA --rotate left (same problem when both displays are rotated) I've tried to play with the "transform" option, but it didn't lead to any success (and the option is not documented at all so it's not so easy to use). I don't know how related it is, but in addition xrandr reports an effective size of 1200x1921 instead of the expected 1200x1920.
