I'm getting basically the same thing with a different library:
------- Loading ref_pbgl.so -------
LoadLibrary("ref_pbgl.so") failed: libX11.so.6: cannot open shared object file: No such file or directory
recursive shutdown
Error: Couldn't load gl refresh!
Available libraries:
$/usr/local/games/paintball2$ locate libX11.so*
/usr/lib/libX11.so.6
/usr/lib/libX11.so.6.2.0
/usr/local/games/paintball2/libX11.so.6 //symlink
I've tried them both. It's like PB2 was looking for the lib in a totally different directory...
Running on ubuntu 64 bit, intel E4300, nvidia gf7600gs.
An idiot-proof graphical installer would bring this game to whole new level. PB could really rock the Linux game scene among all the fresh Ubuntu n00bs like me if the installation would carry out without command line tweaking.
