The only way to utilize the radeon card is for offscreen rendering (radeon renders application frame and the frame is copied to the intel card for display). You need the new gpu hotplug features in xserver 1.13.x or 1.14 to utilize the card in that manner. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
