A quick update on my earlier posting: After disabling the "Composite" extension, I no longer get the UBB warning in the Xorg.0.log, but I still get the error and slow drawing with tksurfer.

Hi,
In response to the message below, I have been getting the exact same error when running tksurfer on a particular workstation. tksurfer does display correctly, but the drawing is very slow, as if running remotely (or not using the video card). This happens with versions 3.0.5 and 4.5.0.
I tried uninstalling and reinstalling the nvidia driver, but that didn't help.
glxgears and glxinfo work fine, no warnings or error messages.
In Xorg.0.log, there is one warning: (WW) NVIDIA(0): UBB is incompatible with the Composite extension. Disabling (WW) NVIDIA(0): UBB.
After googling, I found that UBB stands for Unified Back Buffer. http://http.download.nvidia.com/XFree86/Linux-x86/1.0-8178/README/appendix-k... This only applies to Quadro GPUs. This particular workstation has this type: NVIDIA GPU Quadro FX 580
I haven't yet found a solution. Evan, do you have a Quadro GPU? Did you find a solution?

Dear freesurfer community,
I am currently trying to view one of the surfaces generated by recon-all command in tksurfer but when I enter the command:
tksurfer LuceHR_FS_SURF lh inflated.nofix
I receive a series of errors that look like this:
Received X error! Error code : 1 Request code : 147 Minor code : 181
Error text : 'BadRequest (invalid request code or no such operation)'
Subsequently the surface window does not display what I would believe is the surface I am trying to view and then the only way I can exit the tksurfer environment is by exiting the terminal that I invoked it in.
Any ideas or solutions?
Thank you very much,
Evan Luther
