Alt-Tab does not work under Xfce or Gnome

kosmik · 05-12-2007, 05:00 AM

Hi,

recently, i've upgraded Xorg, to modular version 7.2, but since that, i've got problem with Alt key. When I run gnome or xfce4 desktop, Alt key behaves strangely...It does not work for anything. Ctrl-Alt-Fn is ignored, Alt-Tab and Alt-Shift too. (to switch keyboard layouts, Shift-Alt must be pressed,, switching window focus or jumping to another terminal is not working)

Hovever, when I start KDE, everything looks ok. Also when I run some OS under vmware (under gnome/xfce running), guest-os responses to alt-tab(or other alt-based shortcuts) clearly...

Does someone know, how to repair Alt-key, or what is wrong??

Thanks.

Code:

$ egrep -i 'kb|key' /var/log/Xorg.0.log

I'm having the same problem on XFCE on Sidux, did you find a resolution?
