Hi , I have a problem with OpenGL installation, it has been the problem since I'd gone out of drive space in my Linux installation partition earlier.The Problem Persists even when I have cleaned up some space on The Partition (about 2G Free Now). when I try to run OpenGL Information app it says : can not initialise OpenGL, and glxgears command reverts the followings:

X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 157 (ATIFGLEXTENSION)
Minor opcode of failed request: 66 ()
Serial number of failed request: 13
Current serial number in output stream: 13

every video player which i've tried to change its renderer to OpenGL type has stopped working and has not come up any more to now.It does not respond in the Desktop Effects section either.
I'm using Linux Mint Rosa. What could I do for that? Thank you.

Which Desktop? Cinnamon? Mate? KDE?

Hi, I forgot to say, it's KDE
