Clipboard working incorrect with java-applications (x2go + xpra)

[dimti]

How to repeat

xpra start :100

(launch app1)

xpra start :101

(launch app2)

xpra attach :100
xpra attach :101

Actual result
Clipboard working with system and xpra :101
Clipboard working inside only in xpra :100

I unable copy from system to xpra :100. Or from it.

Need result:
Clipboard working between all xpra inctances and client-system

[Antoine Martin]

Did you look at trac/wiki/Clipboard? Do you have a clipboard manager or a VM?
What server / client OS? etc..

Just tested and this works fine here.

[Antoine Martin]

Sounds to me like this is covered in the wiki link above.
If you still have problems, please post both client and server output with the -d clipboard flag.

I have another problem (maybe similar to first of describe issue):
Clipboard working its OK.
But in Java-applications working not all.

A) I intention to copy text from my browser into my IDE(Java). For complete that task - me need use another programm in xpra session (not java, in this case - geany)
So.

1. On my computer - launched normal X11 session. I open web-browser.
2. Start xpra on :100. Start Java IDE on DISPLAY=:100.
3. Ctrl-C text from web-browser.

3.5 Ctrl-V on Java IDE - nothing. I unable paste from cliboard (clipboard is empty)

4. Open Geany on DISPLAY=:100.
5. Paste clipboard content into geany.
6. Copy text-content from geany
7. Paste from cliboard into Java IDE (working)

For reverse task - I use similar algorythm.

How to I fetch more info about of this problem. Actually start xpra with -d clipboard flag for this reasons?

Thanks you for your patience!

[Antoine Martin]

Which Java IDE is causing you problems?

Yes, the -d clipboard flag can be used for both client and server clipboard debugging.

[dimti]

I use two java-apps: PHPStorm, Jira CLient (Alm works)
In all apps cliboard working with help of non-java app only

-d cliboard on client (copy from default X11-session, paste into PHPStorm (not work), paste into geany, copy from geany, paste into PHPStorm)

Your log file is not annotated, so I am not 100% sure what is happening when.
You have not answered the questions about which OS / distro / version you are using for both client and server.

But:

copy from default X11-session

How do you do this exactly?

Did you have a look at the wiki/Clipboard link?
I suspect that some of your applications are copy+pasting from the CLIPBOARD clipboard, and others from PRIMARY. You can very this using xclip in your xpra session to inspect the contents of the clipboard.

I strongly suspect that this not really a bug in xpra - the best we could do would be to allow you to choose which clipboard we sync to/from.

insert into java (log is empty, insert is successfully, realy no log)

Code with header "Testing the clipboard" (by link) - work is ok. Xclip set and show correctly content

default X11-session - that launched on x2go. Xpra attached into x2go-session (desktop environment - xfce4)

OS ArchLinux?. xpra server and xpra client on same computer. OS launched with systemd-nspawn container (Modified chroot).

I suspect that some of your applications are copy+pasting from the CLIPBOARD clipboard, and others from PRIMARY. You can very this using xclip in your xpra session to inspect the contents of the clipboard.

When i copy content from X11-xfce4. I have that in CLIPBOARD, and in PRIMARY buffer.
When i copy content from geany (helper programm, launhced on xpra session), i have similar situation. Content available from PRIMARY and from CLIPBOARD.

But, if i not use geany-helper-app, i unable to insert that content into java-app.

PS: If i launch java-app on X11-xfce4. I unable to copy-paste from xpra into x11-xfce4. (If use geany-helper (started on x11-xfce4) - copy-paste is work)

Please - change heading of this bug: Clipboard working incorrect with java-applications (x2go + xpra)

[Antoine Martin]

In the future, please mention x2go from the onset!

I don't think we want to support this sort of setup: just like having multiple clipboard managers, this is unlikely to work.

If you can reproduce this bug without using any clipboard manager or x2go, we can take a look.

[dimti]

I check interest log-message on attached xpra client:

2015-02-05 19:19:23,327 clipboard toggled to off by the server, reason: more than 10 clipboard requests per second!

Some that bug in x2go client - x2go sniffing clipboard. After turn off x2go clipboard sync features - xpra and x2go clipboard worked perfectly
