Hello Developers,

 

I’m trying to use fsxvfb to run freeview and save some snapshots, but I can’t get it to run.  The command I’m executing is:

“fsxvfb freeview -v brainmask.mgz -ss pic1.jpg --quit"

 

The output I get is:

this pid 23712

setting display to 86

[1] 23721

pid 23721

Starting command freeview -v brainmask.mgz -ss pic1.jpg --quit

Falling back to using screens root_visual.

Falling back to using screens root_visual.

Falling back to using screens root_visual.

Falling back to using screens root_visual.

Segmentation fault (core dumped)

Program exited normally.

 

No image is saved.  If I run the command without fsxvfb, it executes successfully ending up with a saved image, although it still gives an error:

X server does not support XInput 2

QXcbConnection: XCB error: 1 (BadRequest), sequence: 167, resource id: 133, major code: 130 (Unknown), minor code: 47

QXcbConnection: XCB error: 1 (BadRequest), sequence: 167, resource id: 133, major code: 130 (Unknown), minor code: 47

 

Also, I can successfully run the AFNI command @snapshot_volreg to output an image, and that script also uses xvfb, so I don’t believe it’s a general problem with xvfb.

 

Finally, my environment by default uses freesurfer version 6.0.0, but I’ve run the commands “export FREESURFER_HOME=/usr/global/freesurfer/7.4.1” followed by “source /usr/global/freesurfer/7.4.1/SetUpFreeSurfer.sh” to temporarily change the version.

 

Other info:

1. Freesurfer version: freesurfer-linux-centos7_x86_64-7.4.1-20230613-7eb8460
2. Platform: Ubuntu 16.04.7 LTS
3. uname -a: Linux [nodename] 4.4.0-206-generic #238-Ubuntu SMP Tue Mar 16 07:52:37 UTC 2021 x86_64 x86_64 x864_64 GNU/Linux
4. I am connecting remotely via X2Go to a MATE setup, which then connects to the compute node.

 

I only saw 5 questions referring to xvfb on the archive, and most questions about xvfb I found online seem to not apply to my situation.

 

Thanks very much for any help!

Dani
