Bug Description

Reporting to X-Server as I don't know where else this could be caused.

After upgrading to Karmic I now have the strange behavior that not only ALT-CTRL-F[1-8] switches to the text console from X-Server, but also ALT-F[1-8] does this switching. I don't know where this comes from, but it breaks lots of stuff, i.e. ALT-F4 to close an app, ALT-F2 to open the quick-start-applet, ...

Strange thing is that if I switch back to the X-Server from the text console with ALT-F7, the actual keyboard action is executed in the X-Server, i.e. if I press ALT-F4, the text console is shown, when I switch back, the current application is closed!

Every time I switch (either with ALT-CTRL-F[1-8] or with ALT-F[1-8]), the following is printed to the system log:

I saw that restarting fixes this for some time, but it reappears and it "survives" a hibernate/resume.

Logging in/out does not help.

Restarting kdm does help for a while until it reappears.

Cannot yet say for sure if hibernate/resume is related, but might be.

Dominik Stadler (dominik-stadler) wrote on 2009-10-30:

I think it only happens after I hibernate/resume using the default swsusp functionality.

I have a kernel that has both, TuxOnIce and the standard swsusp functionality from the TuxOnIce PPA. If I hibernate/resume using TuxOnIce via the "hibernate" script, it works fine, if I use the standard hibernate-option in the KDE Menu, I have the problem described above after I resume.

I have it reproducible here, anything that I can provide to aid in debugging this? Where would I start?

Dominik Stadler (dominik-stadler) wrote on 2009-11-15:

I did some more investigation, this is what I came up with:

It seems to be depending on the kernel and the type of hibernate/resume that is used.

- For stock kernels from Karmic with swsusp it does NOT happen
- For TuxOnIce-enalbed kernels from the TuxOnIce PPA it HAPPENS
- If I download pre-kernel 2.6.31-16.51~pre2 from the PPA at https://launchpad.net/~stefan-bader-canonical/+archive/karmic, it does NOT happen
- If I patch pre-kernel 2.6.31-16.51~pre2 from the PPA at https://launchpad.net/~stefan-bader-canonical/+archive/karmic with TuxOnIce patches from 20091009, it does NOT happen

so it seems to be introduced in the TuxOnIce sources between the patch-release 20091009 and the version of TuxOnIce used for building the kernel on the TuxOnIce-PPA.

I don't use TuxOnIce, but I observe the same problem. I've attached my bug report by apport-cli. We should reopen the bug.

st_'s report makes perfect sense to me. TuxOnIce doesn't touch drivers so the issue would have to be caused by differences in the underlying kernel.

Reopening on st_'s behalf.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

For the record, on the tuxonice mailing list, the following possible solution was given, see http://lists.tuxonice.net/pipermail/tuxonice-users/2010-August/000511.html:
" If you are on intel graphic chipset(KMS) and you use pm-utils, I think I
have some clues about the issue.

If you dig deep into pm-hibernate code, you'll see that the no-chvt quirk is
used in this case. According to my experience this is bad, I think this
switches keyboard into xlate mode (same as you would doing alt-sysrq-R, but
can't be really switched back into normal mode). The only way I discovered to
prevent this is disabling the no-chvt quirk. My ugly hack consists of
commenting a line like this (comment already included):
# add_parameters --quirk-no-chvt
in the file /usr/lib/pm-utils/sleep.d/98video-quirk-db-handler: 360 (on my
Debian sid). I have pm-utils 1.3.0

This code is part of the suspend|hibernate case when using_kms."

The same bug affected me after upgrade to 10.04 LTS on a Toshiba with Nvidia video card, and also on a fresh install of 10.10 on ThinkPad X200T with Intel Mobile 4 Series Chipset Integrated Graphics Controller. Looks like a long standing and persistent problem in Ubuntu.

Related bug: bug 520546

This same bug is reported a couple more times. Seems that console-cyrillic is triggering the problem.
Uninstalling the package or disabling Bootsetup in /etc/console-cyrillic fixes the problem, but leaves text console without Cyrillic support. The Cyrillic support can be enabled manually by running /usr/bin/cyr from the console.

I've uploaded the patch that fixes the usage of kbd_mode -u in console-cyrillic, see bug 520546
Hopefully the patch fixes the bug.

However, there seems not much sense in installing console-cyrillic in the first place. Most of its functionality is available from console-setup package, which is installed as part of even minimal Ubuntu system. Just run dpkg-reconfigure console-setup and select your keyboard, language, encoding, etc.
