I tried a lot of forums to solve my problem opening armyops but none of them could help me. What happened:
1. I installed Armyops and tried to open it.
2. It worked but to slow so i wanted to change some video settings.
3. I changed OpenGl to software and the game crashed.
4. I tried to re-open but it crashed at start-up with following message:

jasper@LaptopJ://home/jasper/games$ ./armyops
Cheat protection disabled
WARNING: ALC_EXT_capture is subject to change!
Xlib: extension "XiG-SUNDRY-NONSTANDARD" missing on display ":0.0".
Either GL_EXT_bgra or glDrawRangeElements not supported- bailing out.

History:
Exiting due to error

5. I re-installed the game but still the same error.
6. I search for new an updated driver for my ATI Radeon 9000 IGP but still no luck (https://support.ati.com/ics/support/...ge&folderID=27)
7. I downloaded the X-windows version X.Org 6.8 but this also didn't fix the problem

I alredy checked a lot of threads about this but everybody is talking about nVidea and Geforce but I am having an ATI so

I really hope some-one could help me otherwise i have to reformat because my graphics aren't so good anymore.

P.S.: I am using debian for about 3 weeks now so I'm a newbie
