Bug Description

Binary package hint: plymouth

$ lsb_release -rd
Description: Ubuntu maverick (development branch)
Release: 10.10

Using plymouth_0.8.2-2ubuntu2

After Xserver started, plymouthd is still running. And keys like "Alt-F1", "Alt-Left", "Ctrl-Alt-Delete" are still handled by plymouth.
So, "Alt-F1" from X directs me to tty1. "Ctrl-Alt-Delete" restarts computer.

If I stop plymouth manually and restart xserver, everything goes ok

Just today noticed, that there's no need to stop plymouth service.
I can restart X-server using Alt-E after having kdm (using kubuntu) loaded, and after this everything goes as expected - Alt-F1 doesn't switch to the first terminal.

Maybe the problem is that X-server loads too early, earlier than some service.

It still can be confirmed.
Another netbook (eeepc 1018p), another OS (freshly installed maverick, upgraded to natty).
The problem exists.

Just got this on Natty. Pressing Alt+F4 opens the tty4, when I press Alt+F7 back, the window is getting closed.
The same for Alt+*.

and plymouth is running for both of you after the X server starts? How are you starting the X server? If X is started by gdm, gdm is supposed to stop plymouth before taking over the console.

I use kdm. For about two weeks I haven't been having this problem.
Some people say, it may be a problem of console-cyrillic.
If someone tests, it would be great.

Dmitry Shachnev (mitya57) wrote :

Oh yes, I installed console-cyrillic 2 days ago and now I get it.
I don't have Plymouth running, so should it be a bug in console-cyrillic instead?

Dmitry Shachnev (mitya57) wrote :

I purged console-cyrillic and the problem gone away, so I confirm it's console-cyrillic.
// I can't change the package/status since I get Launchpad timeout errors. Please change them to console-cyrillic/Confirmed.

Steve Langasek (vorlon) wrote :

Ah; sure enough, console-cyrillic incorrectly assumes that it's ok to adjust the console state during startup... which it's not. In particular, calling 'kbd_mode' when the terminal is in raw mode is a no-no.

console-cyrillic needs to be heavily refactored to use the rules described in /lib/udev/console-setup-tty. It should maybe be reduced to nothing more than a config package that sets certain defaults for console-setup.

Fixing this to be a configuration package for console-setup is probably ultimately the right thing to do, but is an insane amount of work that I'm not sure I'm competent to do. It's not even clear to me that they're a conceptual match.

What I'm going to do for Oneiric, I'm afraid, is simply to neuter the init script so that it doesn't interfere with plymouth. You can still run cyr manually after login if you want to force its use.

This bug was fixed in the package console-cyrillic - 0.9-16ubuntu2

console-cyrillic (0.9-16ubuntu2) oneiric; urgency=low

  * Depend on console-setup for now; console-setup-linux does not yet exist
    in Ubuntu.
  * Neuter the init script, as cyr doesn't seem to be compatible with the
    way console-setup sets up consoles in a Plymouth-safe way during boot
    (LP: #597673). You can probably still run it by hand after login.
