Ok, so this sounds like an another HW limitation problem, where the addition of a second head prevents the chipset to drive all screens that the initial resolution and results in poor results.
Intrisically it is a driver bug: the driver shouldn't force the HW to go beyond its limits. Either it should lower the resolution forcefully, or disable support for the 2nd head. ** Changed in: unity Status: Triaged => Invalid -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/830949 Title: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/830949/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
