--- Comment #119 from dk developer@gaminglounge.com --- I just re-installed Ubuntu the other day and compiled Wine 1.7.13. I didn't receive any crashes at all when using the default open source Radeon driver (I'm using an AMD APU). As far as I can tell the only thing preventing me from playing the game is bug #27293 (the typing issue) - I was able to gracefully exit the game every single time. That was a surprise. Framerates were not great (probably a combination of the driver and my weak APU) However with the open source Radeon driver I was able to make it all the way into the lobby and was able to run around and symbol chat with others. I couldn't (normal) chat or type a party name (to create a game). I'm almost positive I could join an existing game had there been one available - I'll try to test that out sometime this weekend. I tested 1.24.3 and Tethealla.
When I installed the official AMD driver (amd-catalyst-13.12-linux-x86.x86_64) I got the same page fault that brian posted for 1.7.13 (d3d8 texture issue).
I don't understand it but I'm hopeful there is something in the open source driver that might help us make some progress. First thing however is to have someone with AMD graphics confirm the open source Radeon driver works.
