Failed to create OpenGL context

[helio]

I have encountered an error message when I was trying to start the commercial visualization software "tecplot360 2006". It says "Failed to create OpenGL context". This software is installed on a gentoo linux machine to which I access only through Ethernet. It used to work without any problem. It still works if I use -mesa flag as in "tecplot -mesa". I am not sure if this has anything to do with the recent "Migration to x.org server 1.5". I contacted the technical support from Tecplot, Inc. They don't seem to have any solution though. Thanks in advance for any suggestions.

Hi helio, I have exactly the same problem. Tecplot on the server, connecting from Windows Vista with PuTTY client and Hummingbird Exceed acting as X-server.

• Err: Failed to create OpenGL context for MainWorkArea.
  Xlib: sequence lost (0x10516 > 0x518) in reply type 0xc!
  Err: Failed to create OpenGL context for MainWorkArea.

I found out that the mesa package is causing the problem. With mesa-6.5.2-r1 it's working fine, mesa-7.3-r1 doesn't work. Also glxgears/glxinfo doesn't work then.

Output of glxinfo with mesa-7.3-r1 installed:

• name of display: localhost:10.0
  Error: couldn't find RGB GLX visual or fbconfig

Does anyone have any idea what has changed in the mesa package? Apparently there's something wrong with OpenGL...

Fugazi, this problem remains unresolved. Yes, I also have similar error messages from glxgears and glxinfo:

glxgears
Error: couldn't get an RGB, Double-buffered visual

glxinfo
name of display: localhost:10.0
Error: couldn't find RGB GLX visual or fbconfig

But I seem able to run tecplot with mesa (version 7.3-r1) as in

tecplot -mesa

So this problem has got something to do with OpenGL. Hope someone can offer some insights.
