Package: gdm
Version: 2.6.0.4-1
Severity: grave
Tags: sid
Justification: renders package unusable
I've seen that someone else have the same problem and I wanna
add some more information to diagnose it:
- gdm doesn't accept input just if used on a kernel with the
framebuffer enabled, and changing the input method doesn't help
- gdm uses the virtual terminal 2 instead of 7 even if in gdm.conf
FirstVT is set to 7
- if I switch to vt1 with CTRL+ALT+1 when X is running and before
gdm starts and then I switch to vt7 with ALT+7 everything works fine:
it seems that the current vt is 2 but gdm expects an input on vt7
- if I kill everything on the current vt using ALT+SYSRQ+K (Sak)
all the processes attached to the vt2 will be killed, but not gdm
that should be connected to the vt7, however I can finally input
something, but not in gdm.
Gdm shows it's input dialogs (and just them) on every virtual terminal.
I thought this problem was related to the interaction between X and
the kernel framebuffer, but the problem disappeared using kdm, so now
I think it's a gdm's bug.
PS
sorry for my bad english, if something is unclear please let me know

Yes. There's a race condition that is very difficult to solve. Other
?dm's don't even make an attempt, and rely on the default policy --
vt7 is where X lives. This bug has been reported many times before,
it's been fixed by this change, which is documented. New installs
have a comment in /etc/inittab telling you not to do this, because the
default X setup used by ever ?dm will conflict with it, and leave you
with no input.
I'm closing this bug, as there really isn't much more we can do to fix it,
unless someone wants to convince the kernel maintainers not to allow this
to happen in the first place...
