/etc/X11/xorg.conf doesn't exist? [duplicate]
Solution 1:
You COULD create your own xorg.conf by typing in a tty (not running gdm) the following:
X -configure
That will create a file called xorg.conf.new
To test the file type X -config xorg.conf.new
If you can load X and see the mouse and a good resolution then you can press CTRL+ALT+BACKSPACE to quit.
Copy then xorg.conf.new to the new location
cp xorg.conf.new /etc/X11/xorg.conf
Run startx
to test.
Also the file does not exist since X.org does not needed anymore for some video cards (as i understand) only some Video cards have xorg.conf because of specific configurations (Like Nvidia and Ati). The rest of the X.org configuration options are in /usr/share/X11 like synaptics.
Now to test out if you have Direct Rendering do this:
glxinfo | grep -i "Direct Rendering"
If it says YES then you can run several games. If it says NO then you might need more configuration. Also run glxgears
to see how many FPS you have. If the glx commands are not there run sudo apt-get install mesa-utils
I can not guarantee that it will make it work for starcraft 2 (Remember you also need to have wine installed)
