Bug#406457: gdm: Keyboard input locks when typing, opening Actions menu too

[Ivan Vilata i Balaguer]

Package: gdm
Version: 2.20.9-1.1
Severity: normal


I'm also experiencing something like this.  When GDM pops up, the keyboard
stops responding as soon as I type anything.  I'm able to do Ctrl+Alt+Fn and
work normally on the console *before* I input anything into GDM, however after
the input Ctrl+Alt+Fn no longer works.  The same kind of lockup happens when I
pop up the Actions menu using the mouse.  In both cases, the mouse can be
moved, but clicks are ignored.  A hard reset is then required (I couldn't chek
logging in by SSH, but the poweroff button is also ignored).

Running the X session with startx gives no problems.

This may be related with #533724, since installing the packages mentioned there
(xserver-xorg-input-kbd and xserver-xorg-input-mouse) allowed me to type in my
login and part of my password before locking.  However, the letters in the
input box moved some pixels back and forth with the cursor blink, or they
seemed to be split horizontally in three parts, the middle one blinking as I
entered characters (yeah, quite odd).
