           Summary: Alt-tab, alt-f2 disables all keyboard input
           Product: kde
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: tue.herlau at gmail.com


Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

I have installed kde 4.2 beta 2 on kubuntu 8.10 using the standard method
(backported packages from jaunty jacklope). Every time i eg press alt-tab,
nothing happends except all keyboard input seems to be disabled (except
ctrl-alt-backspace, ctrl-alt-(1..9) and similar xorg-related shortcuts). The
pointer still works, but when interacting with applications it behaves as if
the alt-key is pressed. 
Besides this the desktop seems to behave normally, ie. no drawing problems, i
can close and minimize applications using the pointer, etc. but the computer
is, of course, completely unusable. 
This is happening on an ibm thinkpad t60 with an ati x1300 which has had no
problems like this with kde 4.0.* and kde 4.1.3. I have tried to remove .kde
and .kderc and purged xorg and all related to the fglrx drivers and
reinstalling using standard methods provided by kubuntu by no luck (because of
this my xorg.conf file is completely trivial).
The keyboard layout is selected correctly in the control center, and the
problem exist with and without desktop effects. If i type 'top' in the command
line everything looks good, no funky new processes or an xorg which takes up
99% cpu or something like that. 

The problem also exist if i press alt-f2 and/or try to interact with certain
plasma components like using get hot stuff. The problem is 100% reproduceable
on my system.

As far as i can tell everything else works as intended.

I think its very likely this is a question of a broken kubuntu package or
something, but i hope this report might be of help anyway. kde 4.2 looks really
good :-).
