Till Kamppeter, as per

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:

Status in “xorg-server” 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
