I'm using Ubuntu 12.10 with kernel 3.6.9 and no problem getting this to work with the gallium (radeon) drivers, however when I try the fglrx drivers I get the following messages in kern.log: Dec 27 13:07:11 gnunn-laptop2 kernel: [ 11.925204] <3>[fglrx:hal_read_VBIOS] *ERROR* Invalid AMD VBIOS! Dec 27 13:07:11 gnunn-laptop2 kernel: [ 11.925207] <3>[fglrx:hal_init_gpu] *ERROR* Failed to read VBIOS! Dec 27 13:07:11 gnunn-laptop2 kernel: [ 11.925208] <6>[fglrx] device open failed with code -1 Which sounds like a similar issue to what was described here. While I generally find the gallium drivers to be more stable and reliable then fglrx, unfortunately fglrx significantly outperforms the open source drivers when it comes to gaming.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
