I have 3 monitors in portrait, for a total of 3600x1920 display resolution with 13.4 amd drivers on Ubuntu 12.04. Sadly when I start CounterStrike, it only uses the primary (left-most) monitor and not the 2 other when using fullscreen mode. It does have 3600x1920 in the video options but it's displaying horizontally compressed on the left most monitory. The card is an ATI Radeon 6870.

Thanks,

What happens with the other two monitors?

This is a duplicate of https://github.com/ValveSoftware/halflife/issues/7. What resolution does the game claim it's using in-game? Also, you may be rubbing up against the fact that the horizontal viewing angle is hardcoded for counterstrike in order to prevent an advantage from a panoramic setup (or 16:10 versus 4:3).

Closing in favor of the existing halflife issue.
