2013-04-10 11:52:21 Till Kamppeter description I have a Lenovo Thinkpad Twist with Core i7 processor and on-chip HD4000 GPU. It has an internal 1366x768 (16:9) display and I have connected and external 1920x1080 (16:9) monitor via HDMI. By default the display gets mirrored with only 1024x768 (4:3) because this is the highest common resolution of the two reported by xrandr. I can switch to a large desktop formed by the two screens with the System Settings (section "Display") with each screen using its native resolution. I can mirror with a higher resolution running the commands: xrandr --addmode HDMI1 1366x768 xrandr --output HDMI1 --mode 1366x768 xrandr --output HDMI1 --mode 1366x768 --same-as LVDS1 This is rather awkward when using a projector. The problem also persists when connecting the external screen to the Mini DisplayPort (with adapter) instead of to the HDMI. The output of "xrandr --prop" with both screens connected in large-desktop-over-both-screens mode (no mirroring): Screen 0: minimum 320 x 200, current 3286 x 1080, maximum 32767 x 32767 LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 277mm x 156mm EDID: 00ffffffffffff0030e47a0300000000 00160103801c10780adce5975a559227 1d505400000001010101010101010101 010101010101241d56d4500016303020 2500159c1000001b0000000000000000 00000000000000000000000000fe004c 4720446973706c61790a2020000000fe 004c503132355748322d534c54310025 BACKLIGHT: 1054 (0x0000041e) range: (0,1054) Backlight: 1054 (0x0000041e) range: (0,1054) scaling mode: Full aspect supported: None Full Center Full aspect 1366x768 59.8*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1920x1080+1366+0 (normal left inverted right x axis y axis) 510mm x 287mm EDID: 00ffffffffffff0015c3692001010101 2d14010380331d78eaee95a3544c9926 0f5054a1080081808140b30081c00101 010101010101023a801871382d40582c 4500fe1f1100001e000000ff00353732 32393131300a20202020000000fc0045 5632333333570a2020202020000000fd 003b3d1f440f000a2020202020200153 02031b41468102031112042309070783 01000067030c001300881e8c0ad08a20 e02d10103e96000403000000188c0ad0 8a20e02d10103e96001009000000188c 0ad090204031200c4055000403000000 188c0ad090204031200c405500100900 000018011d007251d01e206e28550010 090000001e000000000000000000005c Broadcast RGB: Automatic supported: Automatic Full Limited 16:2 audio: auto supported: force-dvi off auto on 1920x1080 60.0*+ 1680x1050 59.9 1280x1024 60.0 1280x960 60.0 1280x720 60.0 1024x768 60.0 800x600 60.3 720x576 50.0 720x480 59.9 640x480 60.0 59.9 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Automatic supported: Automatic Full Limited 16:2 audio: auto supported: force-dvi off auto on HDMI2 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Automatic supported: Automatic Full Limited 16:2 audio: auto supported: force-dvi off auto on DP2 disconnected (normal left inverted right x axis y axis) Broadcast RGB: Automatic supported: Automatic Full Limited 16:2 audio: auto supported: force-dvi off auto on I have a Lenovo Thinkpad Twist with Core i7 processor and on-chip HD4000 GPU.

The problem also persists when connecting the external screen to the Mini DisplayPort (with adapter) instead of to the HDMI. I did not test with 12.10 by myself, but according to the comment from Gizmo Chicken below this worked correctly under 12.10, so this is a regression and not a feature request.

By default the display gets mirrored with only 1024x768 (4:3) because this is the highest common resolution of the two reported by xrandr. I can switch to a large desktop formed by the two screens with the System Settings (section "Display") with each screen using its native resolution. This is a kernel regression from 3.8.0-7-generic to 3.8.0-19. WORKAROUND: I can mirror with a higher resolution running the commands: xrandr --addmode HDMI1 1366x768 xrandr --output HDMI1 --mode 1366x768 xrandr --output HDMI1 --mode 1366x768 --same-as LVDS1 This is rather awkward when using a projector.
