Dear Zeke,

Thanks for stepping in!

$ LIBGL_DEBUG=verbose tkmedit bert orig.mgz libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so libGL error: failed to load driver: swrast Reading /usr/local/freesurfer/tktools/tkm_common.tcl Reading /usr/local/freesurfer/tktools/tkm_wrappers.tcl Reading /usr/local/freesurfer/lib/tcl/fsgdfPlot.tcl Reading /usr/local/freesurfer/tktools/tkUtils.tcl

tkmedit seems fine though.

~$ glxgears libGL error: failed to load driver: swrast libGL error: Try again with LIBGL_DEBUG=verbose for more details. 21147 frames in 5.1 seconds = 4139.989 FPS 5715 frames in 5.0 seconds = 1135.272 FPS 5716 frames in 5.2 seconds = 1108.204 FPS 5715 frames in 5.1 seconds = 1110.123 FPS 5716 frames in 5.2 seconds = 1104.290 FPS 5455 frames in 5.2 seconds = 1058.021 FPS etc.

I see three 3D gears (blue, red and green) which kind of wiggle...

I mean, is this error really a problem or could I possible live with it?

Thank you!

Markus,

I have never seen those errors before. But a little googling suggested perhaps running the program as follows:

~$ LIBGL_DEBUG=verbose ./tkmedit bert orig.mgz

Im a little at a lose at what else to try because we have freesurfer installed on pretty much stock Ubuntu platforms and it runs as expected. Could you also try typing "glxgears" and tell me if a 3D window popups up displaying turning gears, or perhaps an error message is displayed?

Dear all,

For the error

freeview.bin: error while loading shared libraries: libjpeg.so.62:
cannot open shared object file: No such file or directory

sudo apt-get install libjpeg62

did the trick. Freeview is running fine

For the error *libGL error: failed to load driver: swrast* *libGL error: Try again with LIBGL_DEBUG=verbose for more details.*

Any ideas?

Thank you in advance! Markus

Dear experts!

I installed freesurfer on a machine running Ubuntu 12.04.

I have got some error messages when testing:

~$ freeview -v $SUBJECTS_DIR/bert/mri/norm.mgz -v
$SUBJECTS_DIR/bert/mri/aseg.mgz:colormap=lut:opacity=0.2 -f
$SUBJECTS_DIR/bert/surf/lh.white:edgecolor=yellow -f
$SUBJECTS_DIR/bert/surf/rh.white:edgecolor=yellow -f
$SUBJECTS_DIR/bert/surf/lh.pial:annot=aparc:edgecolor=red -f
$SUBJECTS_DIR/bert/surf/rh.pial:annot=aparc:edgecolor=red
*freeview.bin: error while loading shared libraries: libjpeg.so.62:

~$ tkmedit bert orig.mgz
*libGL error: failed to load driver: swrast*
*libGL error: Try again with LIBGL_DEBUG=verbose for more details.*

and the same error also for tkurfer.

Thank you for your help!

Kind regards,
Markus
