When I run braid in ubuntu 11.10 with:
sudo /opt/braid/braid -windowed
I get the following output:
Game Startup Error: Unable to set up graphics. Reason: Failed to initialize OpenGL display. To help fix this problem make sure you are running the newest version of your video drivers. Lastly, you could try running this game with the -windowed command-line option.
I am running on an Asus K53SV with an I5 processor.
