Hi,

tested from remote server with bidirecti= onal clipboard Libre Calc to local Libre Calc : if pasting works on the ser= ver it also works on the client. If it doesn't work on the server it al= so doesn't work on the client:

crtl+c, ctrl+v(server): ok, ct= rl+v(client): ok

crtl+c, ctrl+v(server): fail, ctrl+v(client): fa= il

crtl+c, ctrl+v(server): ok, ctrl+v(client): ok

I don'= ;t know the differences between the x2go repo (I have nothing to do with th= is; I am developing solely on the arctica repo) and the arctica repo. But s= ince this is 3.5.99.27 there shouldn't be too many differences, especia= lly regarding clipboard. So this is ok.

The results are interesting (and match my assumptions). Now tha= t we know that the client to server synchronisation is the culprit we = can deduce some problem on the client side. I will scan the logfile later, = maybe it will shine some light on the issue. For now it might be interestin= g to know if the server server clipboard can be pasted _on the client side_= .

Hi,

disabling clipboard via these setting will effectively su= ppress communication between the client and the server regarding clipboard.= All clipboard communication will then happen between libreoffice and the n= xagent on the server side.

So chances are t= hat your communication is too slow. I _think_ playing around with the other= clipboard options will show that it works with one of the "copy from X= to Y" options and not with the other. Can you confirm?

I did the lightweight test on the c= lient side, my local PC at work.


And indeed, if I open= a Mate x2go session to localhost's IP on the Linuxmint 22.1 Mate clien= t (so server and client are the same, just different users) I can NOT repro= duce the issue.


Now I connected from another client/PC= to my PC (so what's usually a client acted now as remote server): the = issue still exists but only in about HALF of the cases, while it previously= existed consistently in every case after the first try.


=

In the original tests the server's were VMs (Proxmox PVE).



Tests with connection settings:


Previously I had the issue while connecting to the reomote server with con= nection LAN (here at work) and probably ADSL (from home). Now I tested the = same remote server with MODEM: the issue still exists.


Then I changed the clipboard from bi-directional (German: "Zwischenabl= age-Modus: Kopieren und Einfügen in beide Richtungen möglich"= to disabled ("Zwischenablage komplett deaktivieren"). The issue is= NOT reproducible anymore.

So now we've found a workaround, good = :)


Setting the keyboard from auto-detect to "Model= pc105, layout de" didn't help.


Are there any = other settings I should test?

I'll recompile nxagent later.

Hi= ,

just to be sure: have you d= one the lightweight test on the server side or the client side?

Assuming you have done the test on the s= erver side. This indicates that the problem is somehow tied to the connecti= on. Can you please check if different connection settings in x2go lead= to different results?

You= 60;don't need to compile x2goserver, just nxagent. Compiling is done li= ke this:
1. check= out nx-libs from ArcticaProject on github
2. run make

If this fails you probably need to install more dependencies. = If it succeeds, you need to repeat that after changing these lines in = nx-X11/programs/Xserver/hw/nxagent/Clipboard.c:

#undef TEST -> #define TEST
#undef DEBUG -> #define DEBUG

After running make again you should = find a new nxagent in nx-X11/programs/Xserver

For the previous non-lightweight-test in twm on the remote Debian Trixie= server I started in that x2go/twm session a terminal and from there soffic= e, since I couldn't find a direct Libreoffice launcher. So I tried this= for the lightweight test - still works:

I agree there must be something specif= ic with newer Libreoffice versions, since I neither found this with other a= pplications, nor with libreoffice 7.3.7. But as just discovered this is onl= y an issue with (remote?) X2Go sessions.

I = have just tried your reproducer with LibreOffice 6.4.7.2 on RockyLinux 8.10= in a rootless NX session without any problems. Maybe this is tied to newer= LibreOffice versions?

You ca= n also do a very lightweight test locally like this:

3. DIS= PLAY=3D:55 soffice -> will open soffice in the nx window.

Maybe we need more debugging inf= ormation which would require to recompile nxagent on your server system.

Hi= ,

thanks for the quick answer.


x2goagent 4.1.0.6= , as provided by the distributions,

so on the affected Debian Trixie/= Sid Mate server:

x2goserver-x2goagent 4.1.0.6-1.1+b1

and on Lin= uxMint 22.1 Mate:

x2goserver-x2goagent 4.1.0.6-1.1build1

To the best of my knowledge there's no clipboard manager runni= ng on the systems, neither on the 2 tested servers nor the 3 clients.

Most systems were just set up recently by myself, and I never used or = even heard about clipboardmanagers before. Neither clipman nor xclipboard a= re installed.

Package: x2goserver

Versi= on: 4.1.0.6-1.1+b1

Severity: normal


Hi,

si= nce an update/reinstallation copy&pasting in Libreoffice in X2Go always= needs to be repeated, only the very first run works instantly.

We fo= und this issue only when using X2Go, but not when working directly on the s= ame machine.

It happens only in Libreoffice (Calc and Writer), but no= t in e.g. Firefox or an editor.

Starting Libreoffice in safe mode (so= ffice --safe-mode) does not help.


Steps to reproduce:

<= p>

Start Libreoffice

ctrl+c, ctrl+v OK

ctrl+c, ctrl+v= FAIL (nothing is inserted)

ctrl+c, ctrl+v FAIL (nothing is inser= ted)


Start Libreoffice

right-click > copy, r= ight-click > paste OK

right-click > copy, right-click > p= aste FAIL (Libreoffice Calc asks where to shift the cells, but then nothing= is inserted)

right-click > copy, right-click > paste FAI= L (Libreoffice Calc asks where to shift the cells, but then nothing is inse= rted)


Workaround:

ctrl+c, ctrl+v OK

ctrl+c= , ctrl+c, ctrl+v OK

ctrl+c, ctrl+c, ctrl+v OK


<= p>Tested affected servers:

Debian Trixie/Sid Mate (libreoffice 4:24.8= .5-2 amd64, x2goserver 4.1.0.6-1.1+b1)

LinuxMint 22.1 Mate (libreoffi= ce 4:24.2.7-0ubuntu0.24.04.2, x2goserver 4.1.0.6-1.1build1)


=

Previously not affected server:

LinuxMint 21.3 Mate (libreoffi= ce 1:7.3.7-0ubuntu0.22.04.8, x2goserver 4.1.0.3-5)


Tested = Clients:

Debian Trixie (x2goclient 4.1.2.3-3)

Linuxmint 22.1 (x= 2goclient 4.1.2.3-1build3)

Win10 (X2GoClient 4.1.2.2), with the X.org= server option "do not use primary clipboard" both checked and unch= ecked


I reported this issue only here, not with the distro= s or Libreoffice. Please tell me if I should otherwise or if I should provi= de additional info or tests.


My boss is willing to pay for= a solution. Just contact me.


Thanks in advance and th= anks for all your work!
