Gnome-terminal + xpra start/attach issues

[stdedos]

Continuing from #1997 for the gnome-terminal

I have the issue that
$ xpra start :30 --start-child=gnome-terminal --terminate-children=yes --exit-with-children=yes

fails most of the times, whereas
$ xpra start :30 --start-child=xterm --terminate-children=yes --exit-with-children=yes
starts correctly.

$ xpra start :30 --start-child=xterm --terminate-children=yes --exit-with-children=yes
and then gnome-terminal works all the time.

Bugs:

1. After xpra start :30 [...] I need to xpra attach :30 [...]. Is that expected?

2.

• $ xpra start :30 --start-child=xterm --terminate-children=yes --exit-with-children=yes
• Then start gnome-terminal
• Disconnect
• Reattach
• gnome-terminal works, but sometimes (1 out of 7-10) xterm is frozen. Killing and re-attaching the xpra window fixes that

Yes.
You can do all in one with --attach=yes.

but sometimes (1 out of 7-10) xterm is frozen

Do I need to start again or just detach + re-attach to trigger this?
Your log is full of:

Warning: more than 30 clipboard requests per second!

My guess is that you have a clipboard loop. Disable clipboard or disable the other tool that is doing the clipboard synchronization.
This is probably not a bug.

Replying to Antoine Martin:

I understand that I am not good at bug reports. However, since I've taken xpra Information > Report Bug, I am not sure what did I miss.

$ xpra start goes from/to Ubuntu 16.04.5, but this is the only thing that comes to mind.

Do I need to start again or just detach + re-attach to trigger this?

Detach and re-attach is enough.

My guess is that you have a clipboard loop. Disable clipboard or disable the other tool that is doing the clipboard synchronization.

Disabling the clipboard was helpful for this session. I am not sure how the loop works, but, I guess since I had other sessions open at the same time, maybe the sync was complicated?

There was no "external" connection; neither a shadow server. Only multiples of xterm, gnome-terminal

I am not sure how the loop works, but, I guess since I had other sessions open at the same time, maybe the sync was complicated?

If any of the sessions is connected at either end (server or client) to a tool that abuses the X11 clipboard synchronization mechanism, you will see this problem.

The usual culprits are: synergy, virtualbox, clipboard managers, etc..

It happened again. Unfortunately, I have no replication instructions :/

I ran the command once, it gave me the empty window. I ran it again, and I collected all the diagnostics through that session :/

I hope the collected diagnostics are helpful

command

"C:\Program Files\Xpra\xpra_cmd" start ssh://user@ip/ --webcam=no --speaker=off --microphone=off --opengl=no --start=gnome-terminal

Note that cliboard sync was on. But it doesn't matter (I hope), because I got it happening 1 times out of 3~5, even with client clipboard off

"C:\Program Files\Xpra\xpra_cmd" start ssh://sntentos@172.16.57.121/ --webcam=no --cliboard=no --speaker=off --microphone=off --opengl=no --start=gnome-terminal
