Issues and Solutions
Update date: 2021.11.01
Unable to connect to nx1 and nx2 with noMachine. Waiting for IDRE team's reply.
Update date: 2021.10.19
FSL 6.0.3 has been re-installed and the FSLeyes in this version is working in x2go and noMachine.
Update date: 2021.10.15
Here's a list of the known issues after Hoffman2 maintenance
Known issue 1
x2go and noMachine interface looks froze or in full screen mode, user cannot find menu bar.
Solution:
If you are using GNOME as the desktop interface, please change to MATE. KDE works as well but you might have to delete the ~/.x2go and ~/.x2goclient in your local machine (with MacOS).
Known issue 2
FSLeyes in FSL 6.0.4 and 6.0.3 does not load GUI on x2go and noMachine (Other versions work, as well as fslview)
Solution (for both x2go and noMachine):
For FSLeyes in FSL 6.0.4, type in the following command line after you start interactive session, and before you run fsleyes
unset LIBGL_ALWAYS_INDIRECT
For FSLeyes in FSL 6.0.3, fsleyes will be upgraded shortly to fix the current issue.
Known issue 3
FreeView GUI opens but cannot load images successfully
Solution:
In noMachine, use "unset LIBGL_ALWAYS_INDIRECT" command should fix the issue
In x2go, "unset LIBGL_ALWAYS_INDIRECT" does not seem to work all the time. We are still looking into it.
Known issue 4
Jupyter Notebook does not open properly with IDRE's script h2jupynb
Reason: The previous version of this script which was used before the maintenance tries to load Python/3.7.1 which does not exit in CentOS 7 after the upgrade.
Solution:
Download the newest h2jupynb script from IDRE's gitlab

Solution:
Run "unset LIBGL_ALWAYS_INDIRECT" command in the terminal after you start interactive mode and before you launch Matlab GUI.
