Lan,

Try adding this to the end of your /etc/X11/xorg.conf file:

Section "Extensions" Option "Composite" "false" EndSection

You will need to reboot your X11 server after doing so.

I'm running stable version of freesurfer 4.05 on 64 bit ubuntu 7.10. Every time when I tried to run the qdec, it generated the error message below.

Reading /apps/freesurfer/freesurfer/lib/tcl/tkUtils.tcl

Using /apps/freesurfer/freesurfer/lib/tcl/fsgdfPlot.tcl X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 66 (X_PolySegment) Serial number of failed request: 6022 Current serial number in output stream: 6025

[1] Exit 1 qdec

anyone know what's the problem? thanks Lan _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
