I am experiencing exactly the same problem as macat. I have Kubuntu Hardy on a Dell Inspiron 6400 with a Intel 945 graphics card and the laptop is connected to an external monitor (1680x1050). I always turn off the laptop monitor (usign xrandr). The external monitor suddenly goes black or grey after some time. I have noticed the following when this happens:
1) There is no mouse pointer, the external screen is completely black or grey. 2) Ctrl-Alt-Backspace restarts the X-server but does not correct the problem (still black screen). A full reboot corrects the problem. 3) Ctrl-Alt-F1 takes me to a console in the laptop screen. 4) The external screen sometimes flickers for a second. 5) I did not have this problem under Kubuntu Gutsy. 6) I do not know if its related but yesterday the whole X-server crashed and could not be recovered with any of the above. I attach the requested outputs. Thanks for any suggestions. ** Attachment added: "Output.tar.gz" http://launchpadlibrarian.net/13957552/Output.tar.gz -- External monitor loss - intel 945 https://bugs.launchpad.net/bugs/193419 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
