game crashes after intro

[jimmytwinkle]

In my case the error occurs only when i turn on the shadows, but now i have another error, when i press ESC to open the main menu the mouse freezes and the keybord doesn't work, so i have to reinitiate the X server by pressing Ctrl + Atl + Backspace. ¿Any idea of what's wrong?

Also, if i put the shaders option anything better than "Very Low" the game has a lot of graphics glitches.

I am having the exact same problems as Capitan Centollo. I am running Ubuntu Gutys amd64 with an ATI HD2400Pro 256 MB. The game isn't really playable with no shadows and with all the graphical glitches. I am using the latest fglrx ati driver (8.3). Any help would be appreciated.
