I get no error messages in the terminal when running tkmedit/tkmsurfer.

Drivers are enabled and up-to-date, and other similar software is working OK (for instance, fslview).

However, I have installed freesurfer in another computer with an nvidia video card and tkmedit looks great. In this one I have an ATI Radeon HD 4670 (maybe a conflictive card, as far as I have read...)

I tried mesa SW X11 and we could say I got an improvement: now the display window doesn't disappear but it is kind of transparent (I more or less see the 'whites' of the volume but those areas supposed to be black or dark grey are actually transparent --it looks pretty cool but not very useful to work with ;). Any other installation that could help? Is there anyone else experiencing this kind of problem with ATI cards?

Thanks again!

Hi Miguel,

As Bruce said, the best thing to do is to make sure you have enabled "Hardware Drivers" for your video card and make sure they are up-to-date. However, if you do not have a video card with the appropriate level of OpenGL support for an application (e.g., if you are running in a VM), I have been able to run tkmedit using the mesa SW X11 implementation in Ubuntu 9.04. You can install it with:

sudo apt-get install libgl1-mesa-swx11

Good luck!
