So, I decided to play CS:GO. I installed Steam with Ubuntu Software Center and then installed CS:GO from Steam. I tried to run it and I got an error: Could not find required OpenGL entry point 'glColorMaskIndexedEXT'! Either your video card is unsupported, or your OpenGL driver needs to be updated. I was searching for solution for about 2 week, but nothing helped. I even had to reinstall Ubuntu because of a login loop XD.
Then I decided to try and use Wine and PlayOnLinux. I installed everything correctly and when I tried to run CS:GO I got and unknown error.
I know that my PC is realy old but when I used to have windows XP installed on it, I could play CS:GO without any problems. Can you guys please tell me what to do in a simple way, step by step? I would be very grateful for your help

Here are some more maybe useful informations:
lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV530 [Radeon X1600 PRO]
glxinfo | grep "OpenGL version"
OpenGL version string: 2.1 Mesa 11.0.2
And here are the links to pages that I visited in hope to find a solution:
