Eschalon only runs in windowed mode

[aniruddha]

I can run lots of games (defcon, darwinia etc) fine on my laptop, but unfortunately I can't run Echalon in full screen mode. It always freezes. Here's the terminal output:

I run Debian 64-bit.

Do you have dual monitors? We cannot get Eschalon to run full-screen here on 32-bit Ubuntu with dual monitors. This is a driver-level issue that is really outside the bounds of what we can fix.

It's a single monitor (laptop). my specs:

Anyone knows where I can get support?

[BasiliskWrangler]

Since the game runs except in a specific mode (full-screen) I can comfortably say that this is a video driver issue.

We (Basilisk Games) didn't write the OpenGL interface code for Eschalon (it is part of the compiler) so there is very little we can do to change the way Eschalon talks to specific video drivers. I would suggest trying different video drivers if there are any available for your chipset. I would also check some Linux-specific forums for help, look through these Linux support forums thoroughly, and also check the forums on www.playgreenhouse.com as I know there is discussions over there on getting 64-bit Linux to run Eschalon.

I am sorry I don't have a better answer for you at this time. As a final suggestion, you could try running the Windows version via WINE and see if you get better performance.

We'll certainly let everyone know if anything changes on this side (i.e. improved OpenGL support for certain chipsets).
