Won't start in Ubuntu 16.10 [SOLVED]

[Uthranuil]

Been googling for two hours and got nowhere. Why doesn't the game launch? It shows me in-game for one second, then nothing. I can't play the game. It was working this morning, and now it's broken.

My guess would be to undo whatever you did to your system since this morning.

or, give much more info on your issue. Log files would be a good place to start.

Well, I just reinstalled Ubuntu 16.04 and upgraded to 16.10. Going back would have to be a last ditch effort, since I was on KDE Neon, before (based on ubuntu 16.04). Theoretically, it should work just the same.

Here's the command line output from steam. (starting steam and running CS)

So I found a workaround. Since CS runs on the Unity engine, I discovered this error applies to other games. In particular, the displaymanager error

displaymanager : xrandr version warning. 1.5

It's not an ideal solution, but it gets the game running, and so far I have found no bugs afterward.

In properties/launch options, I set set the arguments

-screen-fullscreen 0 -screen-width 1600 -screen-height 900

I hope this helps anyone else who might have this displaymanager error.
