There seem to be two separate issues here. I've managed to find a fix in some of the ubuntu forums for the first issue, and while I don't have the links, I can share them here as I've just put them into practice this morning:
TO THOSE WITH THE "BadDevice" ERROR: I fixed this error by removing a few lines from my xorg.conf file. Apparently the default file contains lines that handle input from tablet devices. If you don't have a tablet device, X will complain. You want to find all unused input devices and comment them out, like this: #Section "InputDevice" # Driver "wacom" # Identifier "stylus" # Option "Device" "/dev/input/wacom" # Option "Type" "stylus" # Option "ForceDevice" "ISDV4" # Tablet PC ONLY #EndSection #.. comment out any other unused device And also comment out the corresponding entries in your ServerLayout: Section "ServerLayout" Identifier "Xinerama" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" Screen 2 "Screen2" RightOf "Screen0" InputDevice "Generic Keyboard" InputDevice "Configured Mouse" # InputDevice "stylus" "SendCoreEvents" # InputDevice "cursor" "SendCoreEvents" # InputDevice "eraser" "SendCoreEvents" Option "Xinerama" "on" EndSection -- 'Monitor & Display' module in System Settings is not working. https://bugs.launchpad.net/bugs/88431 You received this bug notification because you are a member of Kubuntu Team, which is a bug contact for kde-guidance in ubuntu. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
