Second session start fails #2247

totaam · 2019-04-02T15:16:49Z

Issue migrated from trac ticket # 2247

component: client | priority: major | resolution: worksforme

2019-04-02 15:16:49: AnthonyJS created the issue

With both client and server newly restarted, the command

xpra start ssh/whirligig --start="gnome-terminal --window-with-profile=Blue" --start=emacs &

starts up normally with terminal and emacs windows as expected.
The command

xpra stop ssh/whirligig

appears to close the session normally.

However, repeating the same xpra start command now produces only the X frame of a terminal window on the client, with nothing inside it except a view of the display background. It does not respond to key presses or mouse clicks. No error messages appear. There seems to be an active connection between client and server. The only way to recover seems to be to reboot at least the client and maybe the server too.

Server is Ubuntu 18.04, xpra version v2.5-r22135
Client is Ubuntu 16.04, xpra version v2.5-22149

The log file contains

Is this a regression?
Does this only affect gnome-terminal? Can you reproduce with an xterm?
What is the client output?
Do you have opengl enabled? (can you try toggling it?)
Can you try the python3 client? (package name is python3-xpra)

Is this a regression?: sorry, don't understand the question.

It does appear to affect only gnome-terminal -- using xterm instead works normally. (But I prefer to use gnome-terminal.)

Client output for the gnome-terminal case is below.

Opengl is enabled (see output below). Toggling it off in the gnome-client case fills the terminal window with a white background, but still unresponsive. Toggling it on again removes the white background leaving a clear view of display background and any other windows behind.

I haven't tried the python3 client yet.

Is this a regression?: sorry, don't understand the question.
Is this a new bug in version 2.5 or did it also occur with older versions?

I've just tried it in VMs and it worked OK though there were some repaint issues with the gnome-terminal window - though I suspect those are caused by the 3D acceleration in virtualbox.
Maybe r22236 + r22248 helps?
Can you try the latest [https://xpra.org/beta] 3.0 builds?

If that doesn't help, can you post the client -d window,draw,paint log output - as brief as you can make it whilst still exhibiting the problem.

totaam · 2019-04-03T16:20:48Z

2019-04-03 16:20:48: AnthonyJS commented

Is this a regression? No, it is a new bug in 2.5.

I notice that if I ssh to the server after stopping an xpra session that uses gnome-terminal, there are half a dozen or so xpra-related processes still lying around. If I kill them all I can then start a new session normally with gnome-terminal, but it starts with a new display number. If I stop a session that was started with xterm, there are no xpra-related processes left lying around. So it seems that for some reason xpra isn't cleaning up properly after a gnome-terminal session.

I would need assistance from local support to apply the suggested changesets or to install the beta, so I haven't tried those yet.

What are those?
Can you give us the list? What state are they in?
Xpra should only have one process, the server, and potentially one extra process per client for audio forwarding. If you find more than that, chances are that they are not xpra's.

2019-04-03 17:06:33: AnthonyJS commented

My previous comment was mistaken, sorry. If a session using gnome-terminal is successfully stopped, the xpra-related processes are cleaned up. It's only after such a session has failed to start up properly that they are present.
Maybe they should be there, in which case this is a red herring, for which apologies. They are the following:

2019-04-03 17:33:47: antoine commented

Ah, you're right, there are extra ones when starting via ssh:

sh -c xpra initenv; if ... is a shell command that locates xpra to run it

python2 /usr/bin/xpra _proxy_start is how we start a new server and connect to it at the same time (over the ssh channel)

xpra start is the server itself

Xorg-for-Xpra... is the vfb process

pulseaudio is for audio forwarding

All of those should be stopped when you run xpra stop.
If they are not, is the session still visible from xpra list?
(if not, you can kill the xpra start and they should all go away)

When I run xpra stop, the session disappears from xpra list, eventually, but those processes are still present. If I kill xpra start on the client they don't go away. If I start a new session, it starts up with a new display number, even though xpra list finds no sessions.

You have to kill xpra start on the server.

I have killed xpra start processes on the server (3 of them) but some xpra-related processes remain (e.g. 3 pulseaudio processes).

The suggested r22236 + r22248 changesets relate to python3-xpra. At the moment I'm still using python2-xpra. I have python3-xpra installed on the client; do I need it on the server too? How do I invoke it? Is it enough to make /usr/bin/python point to python3? That would lead to problems on the server, which runs some background processes that expect to use python2.

Right, forgot about that.

How do I invoke it?
python3 /usr/bin/xpra ...
Or just uninstall python2-xpra and the /usr/bin/xpra script should pick up the python3 variant automatically.

You can just kill those.
This only happens when xpra fails to shutdown cleanly, or when using xpra exit. So there is definitely something wrong here.

OK, using python3 /usr/bin/xpra ... on the client, the problem is still there, but I get a fleeting error window that says, before it disappears,
OpenGL acceleration failure
No module OpenGL.raw.GLX_types
This may have appeared with python2-xpra, but I think I would have noticed it even though it flashes up only briefly.

Does using python3-xpra on the client automatically pick up python3-xpra on the server?

This error doesn't occur with the python2 builds, it only occurs on Ubuntu 16.04 with the python3 builds: Ubuntu's package of the python-opengl bindings is just too old and buggy.

Does using python3-xpra on the client automatically pick up python3-xpra on the server?
No. The server will use whatever is installed, and python2 if both are installed. (this will change in version 3: python3 will become the default)

So you will need to uninstall python2-xpra on the server, or start the session directly from a server terminal session (rather than using xpra start ssh...)

I hoped that I'd found a clue. So, back to python2-xpra for now. Here's the last part of the client output from

xpra -d window,draw,paint start ssh/whirligig --start="gnome-terminal" &

I hope you can find some clues there -- I don't see any error messages, but the line at 2019-04-04 14:30:36,444 looks odd.

I have uninstalled the beta python3-xpra from both client and server, and installed the stable python3-xpra on both. I find that
python3 /usr/bin/xpra start ssh/whirligig --start="gnome-terminal --window-with-profile=Blue" &
starts up normally, and I can stop the session and start a new one without any of the trouble I experienced previously. I find that the client is using python3-xpra version 2.5:
 $ python3 /usr/bin/xpra --version
xpra v2.5-22149
but the server is using python2-xpra version 3.0:
  $ python2 /usr/bin/xpra --version
xpra v3.0-[r22272](../commit/2325586f74b1757c714c6445e197f8871e437c42)
I do get some error messages from the client:
2019-04-09 11:46:03,021 OpenGL accelerated rendering is not available:
2019-04-09 11:46:03,021  No module named 'OpenGL.raw.GLX._types'; 'OpenGL.raw.GLX' is not a package

but otherwise this combination on client and server seems to be working normally.

but the server is using python2-xpra version 3.0:
That version is from the beta channel. You can downgrade that too if you like.

I do get some error messages from the client:
No module named 'OpenGL.raw.GLX._types'; 'OpenGL.raw.GLX' is not a package
That's just a buggy pyopengl-accelerate package from the Ubuntu repositories.
It's safe to ignore, though as per the warning you won't get opengl acceleration.

Warning: our peer requested the contents of the clipboard
That's caused by the ongoing work in #812.
(this could have caused gnome-terminal to misbehave too)

I think we can close this, and re-open if it re-appears.

I can't reproduce the problem.
It could be related to the cleanup code (ie: #2328) leaving the display behind if the server fails to shutdown cleanly.
