Dear Freesurfer experts,
I have installed the snapshot of freesurfer on my computer in order to learn how to create flat maps with functional overlays. The freesurfer interface comes up nicely and data processing seems to work properly. However, until now I have not been able to view the data with tkmedit and tksurfer. I have studied the FAQomatic but have not been able to resolve this problem. In the case of tkmedit it seems as if the program is unable to write to the screen. However no error messages occur, even when run from the command line. It just starts - works for a second or two - and then stops without displaying anything. Tksurfer on the other hand produces to windows on the screen (one with the inflated image), but the window in which the controls should be displayed remains empty and unresponsive.
I am running Fedora Core 2 with a kernel that is especially compiled to support the latest nvidia drivers for the geforce 4 graphics board in the system I am working on. I have checked the symlinks to the GL drivers that tkmedit and tksurfer calls and all seems to be properly installed. The static versions of the programs also do not work.
Could there be any problem between the GLX drivers from NVIDIA and the freeglut OPENGL utility toolkit (both are the latest version)? Can you give me any suggestion what I could try next in order to get things working?
Thank you,
