[Lenovo Thinkpad X100e] Ctrl+Alt+UpArrow generates no keycode

[Aurélien COUDERC]

On oneiric, I can’t go to workspaces above the current one because the Ctrl+Alt+Up arrow key combination generates no code.
Other equivalents like Ctrl+Alt+{Left,Right,Down} work just fine.
Combinations like Ctrl+Up and Alt+Up also work.

Here’s the output of xev.

[Bryce Harrington (bryce)]

Hey coucouf,

Hi, thanks for reporting this issue during the development period of
Ubuntu.

I notice there's not been further comments to the bug report since the
release came out, would you mind updating us on the status of it in the
release?

Are you still able to reproduce the issue? If not, do you think the bug
report can be closed, or do you think we should continue tracking it?

[Aurélien COUDERC (coucouf)]

Still holds, no magic fix happened.

[Roman Vrublevskiy (roman8422)]

I got it on 12.04 on Lenovo ThinkPad Edge E120.

[Rob Parker (rfdparker)]

Pretty sure I'm seeing the same issue with Ubuntu 12.04[.3] on a Lenovo Thinkpad L420.

Aurélien COUDERC, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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-v3.13-rc3

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.
