hi! the workaround for this problem. it's some kind of strange bug. i have radeon hd 5670 and unity crashed for me too.
1. chceck if your card is still supported in ati closed driver for linux - they do not support 2xxx - 4xxx models in new drivers, so you need to install legacy drivers. 2 if that does not apply to you, do this: - switch back to open drivers - open terminal and do commands: sudo apt-get install linux-source sudo apt-get install linux-headers-3.5.0-17-generic - switch back to closed ati drivers in your software center / software sources / additional drivers - restart computer at this point everything should be working just fine. it worked for me. ati working at full speed with unity and it's so much faster. then open terminal and do this: sudo apt-get install linux-headers-generic workaround found on polish ubuntu forums. thank you! -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1068661 Title: 1002:6740 Unity does not load after installing fglrx-installer Radeon HD 6700M Series To manage notifications about this bug go to: https://bugs.launchpad.net/fglrx/+bug/1068661/+subscriptions _______________________________________________ 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
