This has happened to me on a fresh install of Edgy, under KDE. What I did, to the best of my recollection: 1) Opened Menu -> System Settings -> Monitor and Display 2) Attempted to add a second monitor device (Apple 23 HD), changed resolutions. Changing resolution worked, but second monitor wasn't working. 3) Pressed "Administrator mode", entered my password. 4) Again attempted to add a second monitor. Got the "You must restart the X server" dialog box upon pressing accept. 5) Activated 2nd monitor, and attempted to change resolutions on primary and secondary. I saw the resolution change on my primary monitor, but the 2nd monitor still wasn't working (no picture). I was continuing to get the "please restart X server". 6) Without exiting the System Settings app, I selected Menu -> Log Out-> End Current Session, then at the login screen, menu -> Restart X Server. 7) After the X server restarted, I logged in again, and restarted System Settings (I think it restarted on its own, as part of the desktop restore feature) 8) Clicked on "Monitor and Display" again (not in administrator mode)
Result: Got the error: "The module Monitor & Display could not be loaded. diagnostics: Possible Reasons: An error occurrred during your last KDE upgrade leaving an orphaned control module / You have old third party modules lying around" Got the same result after going to Administrator Mode, too. I don't even know what a "control module" is, or how all this GUI config stuff works, otherwise I'd dig into it a little & attach some relevant files -- displayconfig (KDE) wont open https://launchpad.net/bugs/50411 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
