moblin has set itself as default DE on my karmic however, since it can't connect to wi-fi net, i'd like to revert to gnome. CTRL+ALT+BACKSPACE doesn't work, there is no logout button and flexiserver doesn't work
do i have to remove it ?
Ctrl+Alt+Backspace (i.e. the shortcut which was used to restart the X server) has to be enabled in a different way with respect to previous releases of Ubuntu. This is due to the fact that “DontZap” is no longer an option in the X server and has become an option in XKB instead.
SOLUTION open gnome-keyboard-properties
[* Get to the System->Preferences->Keyboard menu.]
- Select the “Layouts” tab and click on the “Layout Options” button.
- Then select “Key sequence to kill the X server” and enable “Control + Alt + Backspace”.
