** Description changed: 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. + 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. + 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 -
