Till Kamppeter, as per
https://wiki.ubuntu.com/Kernel/KernelBisection#Why_did_the_folders_debian_and_debian.master_disappear.3F
one would want to switch to commit bisecting the mainline kernel as the
tags are linear.

Title:
  8086:0166 [ThinkPad Twist S230u 3347] REGRESSION: Mirroring display
  works only with 1024x768 (4:3) whereas my laptop has 1366x768 (16:9) &
  external monitor 1920x1080 (16:9)

Status in “linux” package in Ubuntu:

Bug description:
  I have a Lenovo Thinkpad Twist with 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.

  This is a kernel regression from 3.8.0-7-generic to 3.8.0-19.

  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
