In my /var/log/Xorg.0.log file, the only errors are as follows:

camille ~ # grep EE /var/log/Xorg.0.log
	(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(EE) Unable to locate/open config file
(II) Loading extension MIT-SCREEN-SAVER
(EE) open /dev/fb0: No such file or directory
(EE) AIGLX error: dlopen of /usr/lib/dri/i915_dri.so failed
(/usr/lib/dri/i915_dri.so: cannot open shared object file: No such file
or directory)
(EE) AIGLX: reverting to software rendering


Now I don't know what /dev/fb0 is, but the /usr/lib/dri/i915_dri.so I
think I should have, but I don't.

camille ~ # locate i915_dri.so 
camille ~ # ls -l /usr/lib/dri
total 2004
-rwxr-xr-x 1 root root 2047960 Apr 12 03:17 swrast_dri.so


Where can I get this file?
