"wayland" is just the protocol library, so not the right place to file this.

As a matter of fact, I just checked the bug happens with scilab,
available in universe. Scilab returns some interesting debug info in the
standard output, which O copy in the attached text file.
NEW INFO.
I didn't see before that matlab was generating a crash log for this. This log
confirms that the error comes from java:
"Assertion in void {anonymous}::mwJavaAbort() at javainit.cpp line 1411:
Fatal Java Exception. See Java Crash Report for details."
The java crash report gives the following:
Operating System: Linux 4.10.0-37-generic #41-Ubuntu SMP Fri Oct 6 20:20:37
UTC 2017 x86_64
Processor ID: x86 Family 6 Model 60 Stepping 3, GenuineIntel

Most curious. It would be of tremendous help if you could find another application that behaves like that, one that is opensource and part of the ubuntu archive preferably. DISPLAY being set to, for example, localhost:10.0, is indicating that the X alls are going through ssh in that particular case.

[Touch-packages] [Bug 1726595] Re: Running Matlab (R) from ssh session with X forwarding doesn't work anymore in 17.10
1- Yes Matlab works as expected without going through ssh.
2- Repeat the above but first do a "ssh -X localhost" triggers the
problem.
3- Both scenarios hold regardless of how I login ("Ubuntu", "Ubuntu on
Xorg" or "Unity").
As you mentionned the DISPLAY variable I checked the following (maybe it was
obvious, but not to me):
- ssh@localhost
- echo $DISPLAY returns localhost:10.0
- export DISPLAY=:0
- matlab & then plot(1,1).
- it works. (tested in "Ubuntu", "Ubuntu on Xorg" and "Unity")

I meant in the ssh localhost test case that you showed. But still, even in the remote case, the "X server" would be your local machine and the X api calls from matlab would be routed to your local X server (wayland or xorg) through the ssh connection. So, just to clarify, matlab works on your localhost when ssh is not used? I.e., just opening a terminal and running "matlab" followed by the plot command? And if you repeat the above but first do a "ssh -X localhost", i.e., the DISPLAY variable is something other than just ":0", then it doesn't work?

[Touch-packages] [Bug 1726595] Re: Running Matlab (R) from ssh session with X forwarding doesn't work anymore in 17.10
Dear Andreas, It was tried in all three modes. Furthermore how do I enforce Xorg when I log from another machine (in my case a windows running Xming) to this one ? I suspect once I connect through ssh with X11 forwarding, the session is Xorg.

Are you using Wayland? If yes, can you try with plain Xorg? To switch to xorg, logout, and on the login screen, after clicking on your name, you will see a small gear icon. Click that to select xorg, and then continue with the login. ** Changed in: openssh (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1726595 Title: Running Matlab (R) from ssh session with X forwarding doesn't work anymore in 17.10 Status in openssh package in Ubuntu: Incomplete Bug description: OBSERVED BEHAVIOR: Matlab stays in busy state when using some functions like "plot" or even "exit", while executing through a ssh tunnel with X11 forwarding.
