openGL not working, BadRequest error

**dransom90** · January 20th, 2013

I'm trying to run an openGL program but I keep getting this message:

X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 34 ()
Serial number of failed request: 34
Current serial number in output stream: 33

What is going on and how do I fix it? Thanks for your help!

Hi ,
more informations will help to solve the problem..

Open a terminal and apply the commands

Code:

lsb_release -rcd ; uname -r
lspci -nnk | grep -iA2 vga
sudo apt-get install mesa-utils
glxinfo | grep -i render

Please click on "New Reply" and put the results inside [CODE] tags to be easier to read. See here how

Thanks

I cannot see any specific problem , your card seems to recognized correctly and driver loaded correctly.

What about openGL version ?

Give the results of this command

Code:

/usr/lib/nux/unity_support_test -p

Thanks

Maybe that program you attempted to run , wants later version of OpenGL ?

For example , steam for Linux (If I remember correctly) wants OpenGL > = 3.0 to run properly.

Thanks

Sorry for a stupid question but what's the best way to update openGL?

I think you cannot. Someone will correct me If I'm wrong , but I think you cannot update the OpenGL (except if you are a developer maybe).

OpenGL is hardware and driver specific , so Intel made this driver (i915) to support for the specific card of yours the OpenGL 2.1.

I have an Intel Ironlake in my Laptop and I have the same problem , I mean I cannot use OpenGL > of 2.1 (even with latest devel - MESA).

So is not mesa problem , is Intel's problem , or if you are a developer (know programming.. etc) you can re-write the driver (i915) for your card to use newer OpenGL version. (Intel's driver is Open Source so the code is available).

Thanks
