Where does xorg.conf find its video drivers

Question

I have the following section in xorg.conf

Section "Device"
    Identifier  "Default Device"
    Driver  "fglrx"
EndSection

In what directory does it look to find the fglrx driver?

Answer 1

the xorg-xserver searche for its drivers in:

/usr/lib/xorg/modules/drivers

with installed 'fglrx' you can find a symlink called fglrx_drv.so which points (essentially) to /usr/lib/fglrx/xorg/modules/drivers/fglrx_drv.so. you can find out the name of the package providing that file by

% dpkg -S /usr/lib/fglrx/xorg/modules/drivers/fglrx_drv.so

which should result in fglrx. you can find out the rest of the files belonging to that package with:

% dpkg -L fglrx
