http://dplogin.com/files/clients/linux/paintball2_build019_linux_64bit_patch.tar.gzExtract this over your build 19 full install. No guarantees, but I got it to run on an Ubuntu 64bit livecd for a couple of maps. It didn't have X-Fi drivers, so I have no idea if sound works or not.
A couple notes:
- On the first load, it may take a really long time to come up -- like several minutes. For some reason, the random number generation in linux is
really, really slow, but I think the more activity you have (keyboard strokes, mouse movement, etc.) the faster it goes. After the initial load, it should be fine.
- The game may crash when changing video modes then typing at the console. Not sure why this is, but if you change your video settings then quit via the menu, it will save them and you can load it back up again with your preferred settings.
