I experienced exactly the same issue after upgrading to xkb-data (1.5-2). After reading this bugreport and the solutions I downgraded to xkb-data (1.3-2) [1] and everything is OK again.
Please also see my bugreport: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=516028 I attached a log from xev there. Cheers, Mark [1] I could not find any copy of version 1.4-1? -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
