so it didn't use Mesa. that was my suspicion

[danieltian77]

Was it suppose to use Mesa not ATI?

How to solve the issue?

[danieltian77]

Still same problem. Running the SimpleGL sample fails with (CL_INVALID_GL_OBJECT)

Ubuntu 11.04, AMD APP SDK 2.4, Catalyst installed via the Ubuntu Additional Driver tool, Radeon HD 5670.

try download a latest driver from amd.com, create packages with "./ati-driver-instaler....run --buildpkg Ubuntu/natty" and after that install them with dpkg -i *.deb

Thanks. I tried your suggestion, still the same result. Any other suggestions? Does it worth to try Ubuntu 10.04 instead of 11.04 (I've been hesitating to do so for I would have to rebuild many things)?

Here is the information from Catalyst Control Center:

Software:

- Catalyst Version                                   11.6

- Driver Packaging Version                   8.84.6-110324a-116088C-ATI

- 2D Driver Version                                 8.86.5

- Catalyst Control Center Version        2.13

- RenderR Version                                  1.3

OpenGL

- OpenGL Provider                                  ATI Technologies Inc.

- OpenGL Renderer                                ATI Radeon HD 5670

- OpenGL Version                                    4.1.10834 Compatibility Profile Context

Also, I have the following Mesa packages installed. Does that matter? Should I remove them after installing the fglrx driver?

libgl1-mesa-glx, libgl1-mesa-dev

libgl1-mesa-dri

libglu1-mesa, libglu1-mesa-dev

mesa-comman-dev, mesa-utils, xscreensaver-gl

Thanks.

well i think you should try 10.04 as it is only official supported ubuntu version. IIRC what i tested ubuntu 10.10 should work too. but i am not 100% sure.

Hi.

I had same problem.(AMD E-350 / Ubuntu(natty) 32bit)

I tryed to reinstall fglrx driver (11.6) .

 sh ./ati-driver-installer-XXXX.run --force

Now everything is ok.

(Priviously I used deb files was created "sh ./ati-driver-installer-11-6-x86.x86_64.run --buildpkg Ubuntu/natty".

 But I encountered this problem.)
