Hi,
If the X server has no GLX extension, SDL_SetVideoMode() segfault. Please
see
#537487.
To reproduct the problem you can do something like:
rm -rf /usr/lib/dri
Restart X and enjoy:
linda:~/public_html/oscs.git/app/models (master)$glxinfo
name of display: :0.0
Xlib: extension "GLX" missing on display ":0.0".

Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".

Then you can try to start opencity.
The attached patch fix the issue.
