I assume by "GPU acceleration not work" you mean 3d rendering is slow. This is unavoidable. Yes, GNOME Shell requires fast "3d" rendering for reasonable performance, so for now it turns itself off when graphics drivers are not able to accelerate that. There are changes in the pipeline to make rendering using the CPU faster, and then that will presumably change. > and dual monitor worked as single monitor. This part might or might not be fixable.

Hope that helps, Jonathan [*] Do you mean that neither unaccelerated rendering without the firmware nor accelerated rendering with the firmware is acceptable to you? In that case, there is not much I can do to help. I am not aware of any project to reverse-engineer the radeon firmware for any model (though it would certainly be valuable)! The only graphics processors in wide use I know of where we know the instruction set used by firmware and are able to write our own are Nvidia processors, thanks to the Nouveau project: https://github.com/pathscale/envytools/blob/master/INSNS http://lwn.net/Articles/367016/ http://nouveau.freedesktop.org/wiki/InstallDRM#Firmware The firmware[**] is software that runs on your GPU, rather than on the CPU. While the CPU component of the Radeon driver (usually simply called "the driver") is indeed free software, and we are able to support it, the firmware is a black box. Luckily it does not change very often --- in fact, while new firmware has occasionally been added, none of the Radeon firmware blobs distributed at http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git;a=summary seem to have ever changed.
