Till Kamppeter, could you please test the latest upstream kernel available
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue. Please do not test the
daily folder, but the one all the way at the bottom. Once you've tested the
upstream kernel, please comment on which kernel version specifically you
tested. If this bug is fixed in the mainline kernel, please add the following
tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For
example:
kernel-fixed-upstream-v3.11
This can be done by clicking on the yellow circle with a black pencil icon next
to the word Tags located at the bottom of the bug description. As well, please
remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

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:
Incomplete
Status in “xorg-server” package in Ubuntu:
Invalid
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
