System Environment: -------------------------- platform: GM45 xserver: 1.6 branch(0d902b05ad910cada46dcc2b85d8b0148aed35e6) 2D driver: master branch(5f347020a52b583e19d333361ea7bf2591255899) kernel: drm-intel-next (00420a63d72354fecd391dd5f1b6d9cba8b1323b) lib/libXrandr : 1.2.91 master branch (0dd24bd6ad3c437f320c5d8e922c479fb61b115f) randrproto : master branch 1.2.99.1 (10bff0be50cf5cf314960bb85c472f1c63d37755) There is still such problems now on GM45. I tested two examples as following: First example: [root@x-gm45b xrandr]# xrandr --output LVDS --scale 0.5x0.5 [root@x-gm45b xrandr]# xrandr --output LVDS --scale 0.5x2 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 148 (RANDR) Minor opcode of failed request: 7 () Serial number of failed request: 18 Current serial number in output stream: 20 [root@x-gm45b xrandr]# xrandr --prop Screen 0: minimum 320 x 200, current 683 x 384, maximum 2048 x 2048 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 683x1536+0+0 (normal left inverted right x axis y axis) 0mm x 0mm (###now display is squeeze into 1/4 region on top, other part of screen is black.) Second example: [root@x-gm45b xrandr]# xrandr --output LVDS --scale 0.5x0.5 [root@x-gm45b xrandr]# xrandr --output LVDS --scale 1.2x0.5 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 148 (RANDR) Minor opcode of failed request: 7 () Serial number of failed request: 18 Current serial number in output stream: 20 [root@x-gm45b xrandr]# xrandr --prop Screen 0: minimum 320 x 200, current 683 x 384, maximum 2048 x 2048 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1640x384+0+0 (normal left inverted right x axis y axis) 0mm x 0mm (###now display is squeeze into 1/3 region on left, other part of screen is black.)
