Garry's Mod is rendering only 1 pixel on screen

[DerpyCZ]

Hi guys,

I'm new here, so if I put this in a wrong section, I am sorry...

I tried to play on a Cinema server, with my friend. It said I don't have flash...
I installed it, and then it doesn't work anymore.
After loading screen, it shows the room and one changing pixel when I move the mouse (figured out, it is a only rendering pixel)
Here are some screenshots:

It isn't so hard to notice.

My PC specs:

OS: Ubuntu 13.10
CPU: Intel Pentium B950 2.1GHZ
RAM: 8GB DDR3
GPU: Intel HD Graphics 2000
(I know, it isn't the best one)

Note: Sandbox with PlayX is still working...

The combination of an Intel HD card and Ubuntu is gonna cause problems, although the problem is probably more to do with the linux version of Garry's mod. Plus, I have no idea how Garry's Mod interacts with Flash on Linux. If you really want this to work, you're probably going to have to use Windows
