Could not find required OpenGL entry point 'glGetError'

Question

I am not able to play "Half-Life-2" on Steam + Ubuntu 14.04 . Error shown in message box on screen:

    Could not find required OpenGL entry pint 'glGetError'! Either your video card is unsupported, or your OpenGL driver needs to be updated.

I have a Dell Inspiron Laptop. My OS is Ubuntu 14.04 and my graphics card is AMD Radeon HD 8600M. I have installed AMD properietry Driver.

The partial output of "glxinfo" is as follows:

    name of display: :0

Answer 1

I found the solution to my problem. To get TF2 to work again all I had to do was remove the symbolic link that I made to get Skype working:

/usr/lib/i386-linux-gnu/mesa/libGL.so.1

The problem now is Skype doesn't work again. I guess I'll just have to remake the symbolic link whenever I want to use Skype until Canonical fixes the seg fault issue with Skype.

Answer 2

I know this is an old thread but removing / deleting this symlink is not a great answer at all. Many other applications depend on this file, although steam requires current drivers.

Please read my solution to this issue:

Answer 3

After a lot of internet searches I have found the solution to this problem.

Please read the comment made on the SteamCommunity forum by Christian Günther.

I just followed these steps and rebooted the system:

sudo rm /usr/lib/i386-linux-gnu/libGL.so.1.2.0
sudo ln -s /usr/lib32/fglrx/fglrx-libGL.so.1.2 /usr/lib/i386-linux-gnu/mesa/libGL.so.1.2.0

Now Half Life is working properly on my system..!
