[Bug 1726595] Re: Running Matlab (R) from ssh session with X forwarding doesn't work anymore in 17.10

2019-08-15 Thread Lorenzo Delana
I have similar problem explained through attachment video, that happens
when I focus opened window by through x11 forwarding using ssh and then
I cannot raise up any of already opened window from the dock.

Steps to reproduce:
- open a gnome terminal so that it happears on the side dock
- xhost +somehost ; ssh -X somehost
- run some gui app and maximize
- click on the window opened by the app so that it got focus
- bug here: now click on terminal on dock and an alert message indicate that is 
ready but it cannot raise even with a second click

Workaround:
- click on the x11 forwarded app titlebar
- click on terminal or other app available on the dock
- the requested app window now raises

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

The xorg-server package covers both native Xorg servers and Xwayland so
filing there... until someone finds somewhere more appropriate.


** Package changed: wayland (Ubuntu) => xorg-server (Ubuntu)

So something to do with opengl over remote X11 connections. I'll switch

2017-10-25 Thread thomas duriez
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
  Host Name:
FATAL ERROR in native method: Nativewindow X11 IOError: Display 0x7fb2cb9e5210 
(localhost:10.0): Resource temporarily unavailable

at sun.awt.X11.XToolkit.run(Unknown Source)
at sun.awt.X11.XToolkit.run(Unknown Source)

Which says that X11 is at fault.

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. It's setup by
the -X parameter.

2017-10-25 Thread thomas duriez
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")

2017-10-24 Thread Andreas Hasenack
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?

Both scenarios above stay the same regardless if you are using wayland
or xorg in Ubuntu Artful?

2017-10-24 Thread thomas duriez
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.  

Thanks for your time.

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
