[X2Go-User] Cross-session copy/paste issue

Sun Feb 21 19:22:26 CET 2021

Hi Uli,

Thank you- concur about images- in the past, copy-paste of them only worked
within a session, not across. My workaround was to paste-save to /tmp on
the host and then open saved image from another session. But nearly all
copy-paste for me is text / URLs.

Re versions of nxagent:

Currently:

[admin at localhost ~]$ dnf list installed | grep nx
nx-libs.x86_64                              3.5.99.26-1.fc33
     @updates
nxagent.x86_64                              3.5.99.26-1.fc33
     @updates
nxproxy.x86_64                              3.5.99.26-1.fc33
     @updates

Previously version release schedule

https://www.spinics.net/lists/fedora-package-announce/msg288622.html

* Fri Jun 19 2020 Orion Poplawski <orion at xxxxxxxx> - 3.5.99.24-1
- Update to 3.5.99.24
* Sat Feb  1 2020 Orion Poplawski <orion at xxxxxxxx> - 3.5.99.23-1
- Update to 3.5.99.23
* Wed Jan 29 2020 Fedora Release Engineering <releng at xxxxxxxxxxxxxxxxx> -
3.5.99.22-2
- Rebuilt for https://fedoraproject.org/wiki/Fedora_32_Mass_Rebuild

So I was previously running what Fedora calls 3.5.99.24.

I can try to downgrade if there is an earlier 3.5.99 on Fedora 33- will
that matter?

Happy to give a go at a replacement build.

I did just note two additional behaviors-

1. cross-session paste does *eventually* complete

-copy of text 1 in session 1
-attempt to paste in session 2
-observe session 2 window freeze
-switch to host window
-paste into host window (success)
-select and recopy in host window
-switch back to session 2- paste of text 1 had completed

So the paste took about 5 seconds

2. cross-session paste payload can be replaced in flight

-copy of text 1 in session 1
-switch to session 2
-attempt to paste (text 1 into session 2)
-observe session 2 window freeze
-switch to another window in session 2
-select and copy text 2 (in another window in session 2)
-switch to the session 2 window attempting to complete the original paste
-note that the paste completed- but using text 2, not text 1

Thanks again!

Jonah
