I have a problem that is quite similar to this. I have a laptop (Compaq Evo N610C) and it's docked, connected to the dock I have a 21" Sony crt.
While upgrading from Kubuntu 7.10 to 8.04 RC this problem turned up, I'll try to explain what I did and what happened. Upgrade went fine, told me to reboot, so I did, everything went fine, logged in for the first time. Both screens show what they're supposed to, I look around a bit for new stuff, don't find anything special except the desktop effects that I enable, just to try, reboot...then the problem starts to appear. Pre kdm - > both monitors are fine, showing everything kdm start -> both monitors are still fine, showing everything kde start -> internal monitor is fine, external looses signal So I disable the effects that I enabled, thinking that they've might caused my problem, doesn't help. Try booting with both kernels in the list. Same result...nothing showing up on external monitor after login and the desktop appears. -- External monitor stopped working after upgrade https://bugs.launchpad.net/bugs/155673 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
