Discussion on: Linux on Windows: WSL with Desktop Environment via RDP

View post

Hello, I followed the instructions for other debian based distros because I am using Ubuntu 18.04 on WSL 2. I am able to get to the Xrdp login in page; however, as soon as I type in my WSL credentials it closes out back to the RDP window.

Can you open a wsl command line end check the logs right after this happens?
I'd check at least those logs:
tail -n 100 /var/log/syslog
tail -n 100 /var/log/xrdp-sesman.log
tail -n 100 var/log/sesman.log

I have the same issue.
/var/log/syslog and /var/log/sesman.log don't exist for me, but /var/log/xrdp-sesman.log contains the following:

I'm not entirely sure what's going on here. Any ideas?

Robin Kretzschmar • Mar 10 '20

Sorry no idea just from the logs.
Can you please post the content of your xorg.conf file?
Maybe this gives a hint.

You could start analyzing it by checking the logs. Open your wsdl env in powershell and check logs located at /var/log for clues.

Muhammad Ridwan Hakim • Apr 30 '20 • Edited

In Ubuntu WSL:
sudo apt-get purge xrdp

then

sudo apt-get install xrdp
sudo apt-get install xfce4
sudo apt-get install xfce4-goodies

configure :
sudo cp /etc/xrdp/xrdp.ini /etc/xrdp/xrdp.ini.bak
sudo sed -i 's/3389/3390/g' /etc/xrdp/xrdp.ini
sudo sed -i 's/max_bpp=32/#max_bpp=32\nmax_bpp=128/g' /etc/xrdp/xrdp.ini
sudo sed -i 's/xserverbpp=24/#xserverbpp=24\nxserverbpp=128/g' /etc/xrdp/xrdp.ini
echo xfce4-session > ~/.xsession

sudo nano /etc/xrdp/startwm.sh
comment these lines to:
#test -x /etc/X11/Xsession && exec /etc/X11/Xsession
#exec /bin/sh /etc/X11/Xsession

add these lines:
# xfce
startxfce4

sudo /etc/init.d/xrdp start

Now in Windows, use Remote Desktop Connection
localhost:3390
then login with Xorg, fill in your username and password.

Those instructions did the trick for me. :)
Thank you very much.

wenrei • Oct 23 '20

Superb, thanks! Editing the startwm.sh file solves the problem of closing the rdp session after entering the login credentials.
FYI: It only works on Ubuntu 20.04, Ubuntu 18 wouldn't work for me

Myron • Dec 13 '20

Thank-you. Worked perfectly. :-)

Vinicius Martins • Jan 30 '21

Thaaaanks! It Worked

Mohammad Abubakar Atiq • May 16 '21

I just change the port to 3400 i hope it dont effect the server but this error is coming up. Any recommendations?

Muhammad Ridwan Hakim • May 16 '21

which error?

Ravil Nugmanov • Jun 20 '20

Hi,
First I followed original instructions, but after connecting over RDP and entering login credentials, it was closing the RDP session immediately.
Then I run all commands from Ridwan's post, and now it works well!
Thank you Robin and Ridwan!
PS: I have Ubuntu 20.04 installed in WSL 2.

Robin Kretzschmar • Jun 21 '20

It seems like newer versions of wsl are having this behavior, good that Ridwan shared his solution and you got it working with it 😊

bagoes • Jun 30 '20

I have run Ubuntu with xfce on WSL1 using VcXsrv, but can't use the browser. I tried to update Windows to be able to try WSL2, it turns out that xfce could not run due to display problems. Finally here I found the solution by Ridwan, of courser Robin also who made the tutorial thread, as well as other commentators. Thanks.

S.P. • Jan 29

Thanks, @rescenic ! I had the same problem, you solution works
