Hi all,

I’m having trouble using freesurfer’s tksurfer program (I only get a sliver of the brain).  Here is the error info I get:

[ghidra: subjects]$ tksurfer 77059 lh pial

surfer: current subjects dir: /home/freesurfer/subjects

surfer: not in "scripts" dir ==> using cwd for session root

surfer: session root data dir ($session) set to:

The driver info (from /etc/X11/xorg.conf) is:

Section "Device"

  BoardName    "ES1000 515E"

  BusID        "14:13:0"

  Driver       "radeon"

  Identifier   "Device[0]"

  Option       "GARTSize" "32"

  Option       "usevnc" "yes"

Section "DRI"

    Group      "video"

    Mode       0660

EndSection

I’m have an onboard ATI ES1000 515E graphics chip.

Any ideas??
