1. My ati Card version 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Robson CE [Radeon HD 6370M/7370M] [1002:68e4] (rev ff) 2. the installation comes from https://wiki.debian.org/AtiHowTo Installation The following procedure will install the open source display driver packages, DRI modules (for 3D acceleration) and driver firmware/microcode: 1)Add "contrib" and "non-free" components to /etc/apt/sources.list, for example: # Debian 8 "Jessie" deb http://http.debian.net/debian/ jessie main contrib non-free 2)Update the list of available packages: # apt-get update 3)Install the firmware-linux-nonfree, libgl1-mesa-dri and xserver-xorg-video-ati packages: # apt-get install firmware-linux-nonfree libgl1-mesa-dri xserver-xorg-video-ati 4)Restart your system to load GPU device firmware. 3. check the output, it successes! dmesg | grep -E 'drm|radeon' | grep -iE 'firmware|microcode' mdl@114-212-83-40:~$ dmesg | grep -E 'drm|radeon' | grep -iE 'firmware|microcode' [ 11.968450] [drm] Loading CEDAR Microcode [ 11.999768] radeon 0000:01:00.0: firmware: direct-loading firmware radeon/CEDAR_pfp.bin [ 12.031284] radeon 0000:01:00.0: firmware: direct-loading firmware radeon/CEDAR_me.bin [ 12.031598] radeon 0000:01:00.0: firmware: direct-loading firmware radeon/CEDAR_rlc.bin [ 12.033820] radeon 0000:01:00.0: firmware: direct-loading firmware radeon/CEDAR_smc.bin [ 12.051580] radeon 0000:01:00.0: firmware: direct-loading firmware radeon/CYPRESS_uvd.bin 4. 3D Acceleration glxinfo | grep rendering direct rendering: Yes 5. I use "glxgears -info" to test the performance. However ,the performance is so bad ! It seems no ati driver at all! 375 frames in 5.0 seconds = 74.986 FPS 300 frames in 5.0 seconds = 59.857 FPS 300 frames in 5.0 seconds = 59.855 FPS 300 frames in 5.0 seconds = 59.854 FPS 6. besides, I found some output I don't understand! "dmesg | grep VGA" show a Firmware Bug , what's meaning of this output?
