WSL xrdp issue (works in 2.0.4, doesn't work in 2.0.9)

[blakeduffey]

Windows Version

Microsoft Windows [Version 10.0.19045.3693]

WSL Version

2.0.9.0

Are you using WSL 1 or WSL 2?

• [ ] WSL 2
• [ ] WSL 1

Kernel Version

5.15.133.1-1

Distro Version

Ubuntu 22.04

Other Software

xrdp

Repro Steps

I've developed steps for using a full desktop environment (via mstsc and xrdp). Over the past few months I've tested

Budgie Cinnamon Enlightenment GNOME KDE LXDE LXQT MATE Xfce

I periodically re-test (to make sure my steps work). I have confirmed that works in 2.0.4 does NOT work in 2.0.9+

EUD-WSLwithdesktop-081223-1524-4.pdf

I just installed a fresh 22.04 instance on wsl 2.0.4 with GNOME. I was immediately able to RDP to the desktop (via mstsc and xrdp). I can see the dock and use apps.

After I update wsl to 2.0.9 - I can connect to xrdp and login, but I don't get a desktop. If I install fresh under 2.0.9, I see the same behavior.

Expected Behavior

Consistent xrdp behavior between 2.0.4 and 2.0.9+

Actual Behavior

Inconsistent xrdp behavior between 2.0.4 and 2.0.9+

GNOME desktop works for me without problem in WSL 2.0.9 when I connect using Windows Remote Desktop, so I can confirm you that it is not the problem of WSL version. I'm on Windows 22H2 Education and installed Ubuntu 22.04.3 inside WSL2. I followed this discussion for the configuration, so the .xsessionrc file is different from your pdf.

[blakeduffey]

I appreciate your feedback @Heng-Zhou. However, I have a working desktop on 2.0.4. I upgrade to 2.0.9 (or 2.0.14) and it doesn't work. I will do some additional testing when time permits.

[OneBlue]

Thank you @blakeduffey. Can you share details about specifically is failing ? We don't support xrdp so to root cause this we'd need to know what exactly is causing gnome to fail in your configuration. I'd recommend looking at straces / logs to see if you can pin point what's going wrong.

[blakeduffey]

@OneBlue - thanks so much for following up. To test this fresh I've done the following:

Uninstall WSL Install WSL 2.0.4 (via the msi)

That gives me the following:

WSL version: 2.0.4.0
Kernel version: 5.15.123.1-1
WSLg version: 1.0.58
MSRDC version: 1.2.4485
Direct3D version: 1.608.2-61064218
DXCore version: 10.0.25880.1000-230602-1350.main
Windows version: 10.0.19045.3693

Install Ubuntu via wsl --install Ubuntu Configure wsl-vpnkit

Export the Ubuntu distro via wsl --export Ubuntu ubuntu.tar

I've then imported that image as UbuntuGNOME, UbuntuKDE, and UbuntuXfce (just for comparison purposes)

I follow my distro-specific steps to setup GNOME, KDE, and Xfce on the 3 separate instances (and bounce xrdp on each).

FWIW I feel confident I could do it with the other desktops I've tested including budgie, cinnamon, MATE, Enlightenment, LXDE and LXQT.

Then I shut everything down wsl --shutdown since xrdp will try to run on the same port on each as it stands.

I bring them up, one at a time, and connect via mstsc (localhost:3390) to verify I can get the desktop

I shut all the instances down via wsl --shutdown

I update to 2.0.14 (as of today) via wsl --update

So Xfce worked KDE crashes and GNOME gives a black screen after logon

I'm actually typing this as I do it - the only thing that has changed is I updated WSL from 2.0.4 to 2.0.14.

[OneBlue]

Thank you @blakeduffey. Unfortunately we don't have internal knowledge of KDE or gnome so if nothing jumps out in their straces / logs, you might need to contact their respective maintainers to help figure out what the issue is.

I can also see that msrdc has been updated in 2.0.10 so transferring to wslg so they can help us figure out if this is related.

[blakeduffey]

@OneBlue - I appreciate the info. I haven't been upgrading as regularly as normal due to the recent issues with wsl-vpnkit. Whatever this change is, it seems to impact multiple desktop environments (budgie, GNOME, KDE). Xfce seems to still work on 2.0.14. Appreciate your hard work.

[blakeduffey]

Thanks much for the redirect. I'm happy to provide any details as would be useful.

[blakeduffey]

I would love to get someone to chime in on this? I can provide logs, etc.

I feel like this some kind of rendering/redraw problem - I can connect to the GNOME instance (for example) and I get a partial desktop (I see the Home folder on a black screen).

[blakeduffey]

So I decided to try to reset everything and try again. I've uninstalled all the WSL bits and installed wsl 2.0.4.

WSL version: 2.0.4.0 Kernel version: 5.15.123.1-1 WSLg version: 1.0.58 MSRDC version: 1.2.4485 Direct3D version: 1.608.2-61064218 DXCore version: 10.0.25880.1000-230602-1350.main Windows version: 10.0.19045.3803

I've installed Ubuntu 22.04 and the GNOME desktop. I can connect to xrdp via remote desktop, no problem.

I shutdown the instances and update wsl to 2.0.14.

wsl --shutdown wsl --update wsl --version

WSL version: 2.0.14.0 Kernel version: 5.15.133.1-1 WSLg version: 1.0.59 MSRDC version: 1.2.4677 Direct3D version: 1.611.1-81528511 DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp Windows version: 10.0.19045.3803

I restart the Ubuntu instance and connect again:

Literally nothing has changed in the 5 minutes except upgrading wsl from 2.0.4 to 2.0.14.

I see this using other desktops (KDE, budgie, etc).

@blakeduffey you don't happen to have somewhere on the logs something about dxgkrnl and/or ioctl failed, do you?

[Segment0895]

@blakeduffey when possible, can you recheck if those errors appear on WSL 2.0.4?

[blakeduffey]

@Segment0895 - I will try that today and report back.

[blakeduffey]

So I uninstalled WSL 2.1.1, installed WSL 2.04

The Ubuntu instance is unchanged, I just left if.

When I try to connect to the instance now via RDP:

When I run sudo grep dxgk /var/log/*

Recheck your screenshot, was the one posted the one you wanted to post?

Thanks

[blakeduffey]

@Segment0895 - it was not :)

I thought I fixed it before anyone saw it. I've replaced.

[Segment0895]

Ok, one theory down.

I'm out of ideas for now.

Thanks for your feedback! Maybe someone else can pick it up from here.

@Segment0895 - I neglected to look at the dates. Those log entries look to be from a couple days ago (and may not be relevant to the testing re: 2.0.4) - let me verify. Please come back ! :)

[blakeduffey]

@Segment0895 -

So I tested again (wsl --shutdown and restart)

Connecting to RDP I do see:

So I think these logs appear whether the problem exists or not

[Segment0895]

Confirm it also happens with XFCE. On XFCE it just happens when opening an app such as the terminal.

Just so this thread doesn't completely fade into oblivion

This issue persists on wsl version 2.2.2.0

Versions of WSL up to 2.0.4 - I was able to install a desktop environment and connect via xrdp (I have documentation for Budgie, Cinnamon, MATE, Xfce, Enlightenment, GNOME, KDE, LXDE and LXQT). After 2.0.4 (and up to 2.2.2.0) - this no longer works.

[Dnzldotexe]

Encountered the same issue on xrdp with Ubuntu 22.04. I haven't tried myself, but, maybe updating the Ubuntu version to 24.04 could solve this? Saw someone from YouTube doing the exact steps as I am, and his xrdp worked.
