Requirements for using Nouveau ============================== You need a Linux kernel that contains a nouveau.ko module which works with the libdrm-nouveau package in Debian. Supported kernels are 2.6.34 and newer, earlier versions lack the nouveau module altogether or contain an incompatible version. If you build your own kernel, you have to enable the module under Device Drivers -> Graphics support -> Direct Rendering Manager (Linux 3.4 and newer) or Device Drivers -> Staging drivers (Linux 3.3 and earlier). Non-vintage Nvidia cards require that microcode (firmware) is uploaded by the driver to the GPU in order to provide any acceleration. The Nouveau project aims to provide the microcode in the kernel driver for all cards, but new hardware usually needs non-free and not readily available firmware for a transitional period. Please check the status at http://nouveau.freedesktop.org/wiki/InstallDRM#Firmware. Incompatibilities with other drivers ==================================== The nouveau kernel module includes a framebuffer driver for the virtual console, giving you a nice high resolution text console. Unfortunately, this is incompatible with other display drivers, including the Nvidia proprietary driver. Among others, the following kernel modules must not be loaded before nouveau: nvidiafb, rivafb and nvidia. Note that vesafb should not be a problem. If you decide to switch to the proprietary driver, it is highly recommended to reboot because it is incompatible with nouveau, and unloading the latter is not easy and may lead to a blank console. Interferences of the Nvidia OpenGL implementation ================================================= The proprietary Nvidia driver comes with its own OpenGL implementation that is incompatible with free drivers. To be able to use OpenGL programs with nouveau, you need to replace the Nvidia files. If you have used the nvidia-glx package or any of its legacy variants, run "update-alternatives --config glx" and select /usr/lib/mesa-diverted, or remove the glx-diversions package and its reverse dependencies. If you ran the Nvidia installer, you may need to reinstall the xserver-xorg-core and libgl1-mesa-glx packages. In either case, restarting X is also necessary. A simple OpenGL test program is glxgears, contained in the mesa-utils package. Further information =================== Please see the nouveau Wiki for more information and possible problems. http://nouveau.freedesktop.org/wiki/ http://nouveau.freedesktop.org/wiki/FAQ http://nouveau.freedesktop.org/wiki/TroubleShooting http://nouveau.freedesktop.org/wiki/KernelModeSetting -- Sven Joachim <svenjoac@gmx.de>, Wed, 11 Apr 2012 17:08:14 +0200
