External Email - Use Caution
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
