Login error with Remote Desktop to Ubuntu server

Solution 1:

I had similar problem, there are several problems with xrdp on ubuntu it seems. I found this page useful for solving some of the others, especially the keyboard problem with non-us keyboard.

As regards the login issue, there needs to be a group setup on the ubuntu machine called "tsusers", i added this group via the gui, but i believe there is a command line tool to do the same. You username that you want to login to xrdp will also need to be a member of this group. so user "john" (you) will need to have a group made "tsusers". Also for inexperienced users (such as myself!), when you login, login as "john", not "John", i believe linux usernames are actually all lowercase not first letter capitalised as it is for the gui login to ubuntu.

Introduction xrdp is a Remote Desktop Protocol (RDP) Server, allowing RDP clients to be presented an X windows desktop to the user.

Setup First install xrdp:

sudo apt-get -y install xrdp

Next, change the encryption level to high from the default low:

sudo nano /etc/xrdp/xrdp.ini
encrypt_level=high

Next, allow just RDP through the local firewall:

sudo ufw allow 3389/tcp

But one thing more

sudo vim /etc/ssh/sshd_config

. Change Password Authentication to yes from no, then save and exit.

Note After making this change, press SHIFT+ : [colon] to open a new command entry box in the vim editor. Type wq, and then press Enter to save changes and exit vim. Restart the SSH daemon to make this change take effect.

 sudo /etc/init.d/ssh restart

Temporarily gain root privileges and change the password for the ubuntu user to a complex password to enhance security. Press the Enter key after typing the command passwd ubuntu, and you will be prompted to enter the new password twice.     

 sudo –i passwd ubuntu

Finally, restart xrdp and you should be able to connect:

sudo /etc/init.d/xrdp restart

The issue is that the configuration has to be adapted.

Either add the user you want to use to the standard tsusers group (which you might have to create first), as defined in /etc/xrdp/sesman.ini, or uncomment the lines in sesman.ini where the group requirements are defined.

Also take care about the keymap/keyset: it has a fallback to the US keymap so special characters are entered in another way.
It might not have been preloaded (or auto-detected) and so has to be generated from the console (km-xxxx.ini in /etc/xrdp)

A new keymap can be created with xrdp-genkeymap, though you might be out of luck if you have for example a Swiss German keymap; then you might have to copy a working km-xxxx.ini file to the /etc/xrdp directory, eg: ch-DE -> km-0807.ini

You might also want to take a look at the logos if you want to adapt the login experience which are located in /usr/share/xrdp or /usr/local/share/xrdp

You might also want to look through the xrdp documentation
