Sometimes my keyboard shortcuts in gnome do not work (ctrl-alt-right for next desktop, ctrl-alt-m for menu, ctrl-alt-b for browser, et cetera)

Sometimes after rebooting they do work.

I wish I could provide more diagnostic information, but, I don't know what is relevant.

Please advise.

It may(?) be a dodgy key.. Have you tried different combinations of Left_Ctrl/Right_Ctrl and Left_Alt/Right_Alt... I've just had a similar thing with my Escape key... I changed the keyboard and I'm back on the road...... – Peter.O Apr 28 '11 at 19:20
PS: run this in the terminal; it bypasses the physical keybpard : xdotool key "Ctrl+Alt+Right" – Peter.O Apr 28 '11 at 19:30
How often do the shortcuts switch between working and not working? Is this consistent between reboots, or do they stop working at some point, or do they randomly start and stop working during a session? Does it matter what window is focused? what applications are running? where the mouse pointer is? If you can, press the keys in an xev window when they aren't running: do you see KeyPress and KeyRelease events for Right, M, …? – Gilles Apr 28 '11 at 20:28
@gilles I'll check with xev next time it happens. @fred thanks for the pointer. next time it happens I'll try it. i dont think its a bad key, the keyboard is brand new, but i'll try using the right ctrl next time. if i come up with any new info i'll post an update. it's hard to recreate on demand. it does require a reboot to fix. – justin cress Apr 28 '11 at 21:21
