I also have this problem (using a laptop with an Intel GMA 945 graphics controller). I can confirm that no crash happens with the following sequence:
Boot laptop with external monitor unplugged, Disable visual effects, Plug in the monitor, Type "xrandr --auto" in Terminal, Go to Display Prefs, Turn laptop monitor off, Keep external monitor on/Set external monitor to max resolution, Fini! Now how can I get the external monitor plugged in without having to go through this process? -- [i945gme] attaching external monitor: laptop display is black, external monitor too, with frozen mouse coursor https://bugs.launchpad.net/bugs/419328 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
