Bug Description

1. Clean install of Ubuntu 18.04LTS desktop on my server.
2. Activated Ubuntu's built in remote desktop sharing and it works without any problems.
3. Installed GNOME-flashback 3.28.0-1ubuntu1 along with the dependencies, and when switching to GNOME-flashback session the keyboard map is obfuscated. Key-map is set to Swedish.
When accessing the computer locally the keyboard works as it should. Switching back to normal GNOME the remote session works as it should.
4.The key-map is not a normal key-map. The standard letters and numbers are correct. Swedish unique letters and the signs like -/´§_( are on the wrong keys or missing completely. AltGR key is not recognized either.

Could you try to improve bug? With better steps how to reproduce this bug. Especially input source / keymap part so I can try to reproduce this. Which input source should I add, what keys should I try, actual and expected results... How do I type Swedish unique letters?

Hi, below here I added each keymap, the standard, with shift and altgr
for both the standard gnome that works fine, and for the gnome
flashback. I substituted dead keys with X for the flashback session,
then you can just compare it the the normal keymap. You will see that
the international letters, and the numbers are in the right place. But
the unique keys are randomly scattered, while some of the symbols have
the posistion of the US keyboard layout.

Can you post output of `setxkbmap -query` for normal and remote desktop? Also might be good idea to report bug upstream - https://gitlab.gnome.org/GNOME/gnome-flashback/issues, I don't think this is Ubuntu specific bug.

`setxkbmap -query` gives the following output:

rules: evdev

However, it seems like this issue is resolved by itself. Have been away from the office this summer and only connected to the servers via SSH. Now it works for me.
