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.html 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? Don _________________________________________________________________________ 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
