My machine is dual boot with Maverick 10.10 (ATI proprietary drivers) and also Natty 11.04 (radeon drivers). I have tried both a 5770 and a 5870 chipset card under both versions of Ubuntu and all 4 combinations fail if the the extra 2Gb DIMM is inserted.
If I leave it with a single 2Gb, they work (apart from a recent issue with a Natty update on the 5770 which causes serious GPU lockups that make the desktop unusable). This other seemingly unrelated issue i being tracked at... https://bugs.launchpad.net/bugs/775575 I will post a photo of the screens (dual screen display configuration) next. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/756540 Title: ATI graphics card fails when RAM increased to 4Gb on Natty Beta _______________________________________________ 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
