Linux support forum for Eschalon: Book I
I updated the other post, but just to recap. I never did get the game to run in 8.10, but it is running in 9.04 beta with the linux 2.6.28 kernel. So, in a few weeks, when 9.04 comes out, this might be a mute issue.
I can confirm, Book I now works for me with Ubuntu 9.04 and the Intel GPU.
