Dear all, I have Fedora-18 64 bit KDE install and and I find that ctrl+alt+backspace does not work. I have try to modify the /usr/share/X11/xorg.conf.d/10-evdev.conf, adding following statement Option "XkbOptions" "terminate:ctrl_alt_bksp" , Then, in my case, at the 10-evdev.conf, there is: ... Section "InputClass" Identifier "system-setup-keyboard" MatchIsKeyboard "on" Option "XkbOptions" "terminate:ctrl_alt_bksp" EndSection ... I remember on FC-17 I can log out/in that way, not on the FC-18 install. Any thought? -- Qingwei Zhang Do something today that your future self will thank you for.
