Thanks @graywolf, I don’t remember setting up anything special in the X server. I have a lot of experience with Linux shell scripts, programming in perl etc, but not much with system management. I’ll attach a screenshot of the installed items when I search for “xkeyboard extension” on the server.
The server is a slice of a real computer that we rent from a cloud computing provider.
When I go to connect with NoMachine, today I need to choose amongst the following “Physical displays” on “Ubuntu X server”: 0, 10, 12-17.
I have logged in using number 11, closed processes there and logged out. Now I am going through them, and for each one I’ll log in, close processes running there and log out. When I get to the last one I’ll reboot.
Thanks again for your help,
Thankyou, @graywolf, here are the sizes of the files on disc (from du -h *):
As you can see, the server only produced errors:
server-setxkbmap.err: XKB extension not present on :11.0
server-xkbcomp.err: Error: XKB extension not present on :11.0
Does this mean I should install XKB extension on the server?
I’ll upload the client files that are larger than zero.
There are probably more keystrokes here than you need — it took me a little while to work out how to click the x to terminate the xev program 🙂 I’m not sure this is all the keys that don’t work, but it might show you what is going on:
Thanks again for looking into this,
Gerald, the #AgentLegacyKeyboard 0 that you list still has the “#” key before it, which usually means that it is commented out, and therefore having no effect.
Would you like to try removing the “#” character in that control file?
Then make NoMachine on your client exit and start it again, and see if that makes a difference.
Yes, gbr, arrow keys don’t work for me either.
The fix that you gave seems pretty complicated. I would have to do quite a bit of research to figure out how to apply it.
It’s a pity that the issue there is marked as “closed”.
I am running the version installed from nomachine_6.9.2_1_x86_64.tar.gz
My machine reports itself as
Linux JimH15 5.3.0-26-generic #28~18.04.1-Ubuntu SMP Wed Dec 18 16:40:14 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
and I am connecting to reports as
Linux langtran 4.15.0-74-generic #83~16.04.1-Ubuntu SMP Wed Dec 18 04:55:53 UTC 2019 i686 i686 i686 GNU/Linux
Also, the End key doesn’t work, so probably Home and similar keys don’t work either.
And, by the way, how did you find a way to post a new item to the forum? I can’t find it 🙁
