Up to "Failed to open device" this is a duplicate of bug #42553 , however, as for the other messages, I am not sure at all.
Could you do any of the following: 1) Update to Edgy. 2) comment out in /etc/X11/xorg.conf: InputDevice "stylus" "SendCoreEvents" InputDevice "cursor" "SendCoreEvents" InputDevice "eraser" "SendCoreEvents" 3) Post the output of "kate", "sudo kate" and "kdesu kate". Thanks in advance. -- X Error: BadDevice https://launchpad.net/bugs/53845 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
