You were probably right about something being out of date. I just installed Crunchbang instead, got same graphics driver (nvidia 331.20) and apt-pinned 0ad on debian sid to get the latest version. Been playing for an hour+ now and no black screen. GPU temp is the same as it was on Mint. Never had this problem in other 3D games. Ive played Dungeon Defenders, Oil Rush, Left 4 dead, world of warcraft (wine), counter-strike, trine 2, brĂ¼tal legend, a few flight simulators and a ton of other games without any problems.
