== amdconfig not found after installation == This scenario is possible when the driver installation has seemingly succeeded and is possibly related to previous fglrx installs, including those through Jockey (i.e. you first used drivers provided by Ubuntu but then upgraded to ones available from AMD's website). When doing amdconfig --initial after driver installation, you might end up not having the amdconfig available at all: <pre>amdconfig: command not found</pre> After booting you might receive X error '(EE) Failed to load module "fglrx" (module does not exist, 0)'. These do not necessarily indicate that the installation has failed completely. On command line, do ls /usr/lib/fglrx/bin and see if the command lists some Ati related programs. If they are listed but not found from /usr/bin, it is possible that the "update-alternatives" fglrx .deb installation does has been ignored. See man update-alternatives for more information about the concept and workings of alternatives. In practice, update-alternatives is supposed to create several symbolic links to the files in the fglrx directory, but it will be ignored if the alternatives for the very related gl_conf entry has been set to manual. Do update-alternatives --get-selections | grep gl_conf and see if the mode is manual instead of auto and if mesa is mentioned instead of fglrx in the path that is printed. In this case you need to sudo update-alternatives --set gl_conf /usr/lib/fglrx/ld.so.conf to set fglrx as the active alternative. You can alternatively (no pun intended) and additionally change the gl_conf into automatic mode before the installation this way: sudo update-alternatives --auto gl_conf After that, the alternatives should automatically be configured correctly when the graphics driver .debs are installed.
