I found a bug in /usr/bin/compiz-manager. When I start compiz-manager, it complains about too many arguments in line 230. This is because in line 225, TEXTURE_LIMIT is initialized but gets the values from both screen 0 and screen 1 since I have two screens (:0.0 and :0.1). $ glxinfo -l | grep GL_MAX_TEXTURE_SIZE | sed 's/.*=[^0-9]//g' 4096 4096 This bug can be solved by adding the "-m1" option to grep or simply using a "|head -n 1" which might be more portable: $ glxinfo -l | grep -m1 GL_MAX_TEXTURE_SIZE | sed 's/.*=[^0-9]//g' 4096 $ glxinfo -l | grep GL_MAX_TEXTURE_SIZE | head -n 1 | sed 's/.*=[^0-9]//g' 4096 so line 225 should read something like TEXTURE_LIMIT=$(glxinfo -l | grep -m1 GL_MAX_TEXTURE_SIZE | sed 's/.*=[^0-9]//g') or TEXTURE_LIMIT=$(glxinfo -l | grep GL_MAX_TEXTURE_SIZE | head -n 1 | sed 's/.*=[^0-9]//g') This way, the bug is solved.

In my opinion, I prefer add -m1 option to grep, because head -n 1 increase the number of syscalls (+1 pipe(), +2 dup(), +1 fork(), + 1 execlp()/execvp() )
In that case we could even eliminate grep completely, and let sed do all the work and only one pipe is left: $ glxinfo -l | sed -nre '/^ *GL_MAX_TEXTURE_SIZE *= */{s///p;q}' 4096 ;-)

Looks good. Thanks for taking care of this.
