reply to comment #62: Here is what I did: - booted up with VGA cable disconnected from laptop - logged in as ordinary user - turned off visual effects in preferences - killed compiz-decorator process (not sure this step is necessary) - connected the VGA cable - ran xrandr --auto: this went OK (no crash) - ran display prefs to use dual-head mode; this went fine. - removed the VGA cable - logged off then on again - turned on visual effects - connected the cable - ran display preferences and X crashed (black screens, external screen is on, it is showing an immobile mouse pointer in the left middle). No response whatsoever to keyboard, mouse or touchpad. I Had to powercycle the machine.
Note: I can use compiz in dual head mode, I just need to connect the VGA cable prior to the start of the X server. -- [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 : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
