Package: compiz-core
Version: 0.7.6-7
Severity: important


compiz fails to start because it cannot read /var/log/Xorg.0.log. 

$compiz --replace &

Checking for Xgl: not present. 
egrep: /var/log/Xorg.0.log: Permission denied

No whitelisted driver found
aborting and using fallback: /usr/bin/metacity

For increased security I'm running with umask 077, which means
/var/log/Xorg.0.log is not read writable by normal users.

$ ls -l Xorg.0.log
-rw------- 1 root root 27106 Jan 30 22:42 Xorg.0.log

The script /usr/bin/compiz assumes /var/log/Xorg.0.log to be readable by
normal users in the function running_under_whitelisted_driver() on line 247.
Changing the permissions for Xorg.0.log fixes the problem. To avoid having
to do this every time I startx, I added a "return 0" at line 260 to skip
this check. This is only a bodge. Presumably another method should be used
to acquire the driver name to check for whitelisting.
