You have been subscribed to a public bug: Since I upgraded from Lucid to Maverick (official release with latest updates), the display with dual non-mirrored monitors does not work. I have a Dell Dimension 9150 with 2 GB RAM, Intel Pentium 4 dual-core 3 GHz CPU and a Radeon X600 graphics chip. This worked fine in Lucid and Windows XP.
My setup: Samsung 17" SyncMaster 171s VGA 60 Hz on left, and 19" Samsung SyncMaster 943 DVI 75 Hz on right, both at 1280 x 1024. The Radeon controller has a VGA and a DVI socket and the two monitors are connected as indicated. Mirrored monitors display fine. But using System -> Monitor Preferences, uncheck "Same image in all monitors", click on Apply, and the right-hand monitor (19" DVI) completely garbles the right half of the display from top to bottom. Also tried 60 Hz, no change. I ran Update Manager to get the latest official updates, googled and tried various suggestions, such as "bleeding.edge" xorg stuff, but it was no help. Not sure if this is supposed to have been resolved or not. So I downgraded to 10.4 where it works fine. Would be great to get an answer as to how to fix this problem - thanks. - Bob Paulson ** Affects: xserver-xorg-video-ati (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: corruption dual-head -- dual monitors garbled display on 10.10 with Radeon X600 https://bugs.launchpad.net/bugs/706890 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ 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
