KDE - OpenGL Issues - Is This Old Graphics Card Still Supported?

English Hardware
#1

Hi,

Have a really old notebook where I installed openSUSE Tumbleweed KDE 64Bit.
Runs fairly well, but OpenGL is not working perfectly?

Graphics adapter is listed below.
How can I troubleshoot OpenGL graphic issues?

Let me know, thanks!

Jesse

Hi,

Sorry, I just saw an earlier post I made which was similar to this one…
I’ve got everything on the 8+ year old notebook working except this issue with OpenGL rendering…

Thanks!

Hi
The card is what it is, if the application your trying to run needs a later version (> 2.1) then nothing you do with that hardware will work…

Also, please re-run the command as your user not root…

How does one determine one has a problem with OpenGL rendering?

Hi
AFAIK it’s just the specs of the GPU model…

Hi,

Ok, I fixed the issue:
Problem was application window theme was not blurred and transparent.
(like Windows Vista/7)

I went into: /System Settings/Workspace Behavior/Desktop Effects/Blur
It was not fully enabled, clicking on full enable fixed the above issue…

Thanks, I am happy now!
