[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Since Mesa 10.2 i get an error when i run steam "OpenGL GLX context is not using direct rendering, which may cause performance problems.
For more information visit https://support.steampowered.com/kb_article.php?ref=9938-EYZB-7457." my glxinfo shows 'direct rendering: Yes'
When i try to run Half-Life 2 i get this:
"Could not find required OpenGL entry point 'glGetError' ! Either your video card is unsupported, or your OpenGL driver needs to be updated."
I have SAPPHIRE HD 7850 1GB, the same error shows on mesa 10.3 and 10.4.
I have Xubuntu 14.10 but the same error shows on other Ubuntu flavors and distributions.
