I can also confirm this issue. I have a dual gpu Core i7 and Radeon HD6450. When I install fglrx, fglrx-updates or Catalyst 12.9 beta the amd driver does not load.
When using the Radeon card, Unity loads but the Intel driver is used: $ fglrxinfo OpenGL vendor string: Intel Inc. OpenGL renderer string: Intel HD Graphics 3000 OPenGL Engine OpenGL version string: 1.4 (2.1. APPLE-8.0.61) -- 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: Unity does not load after installing fglrx-installer 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
