WSLg keeps display always awake (application keeps caret blinking). #172
Description
I am not 100% sure that it's connected, but have checked it a few times and only when app under WSLg was running my displays wouldn't go off.
Environment
Windows build number: 21364
Your Distribution version: Ubuntu 20.04 / 21.04
Your WSLg version: 1.0.19
Steps to reproduce
Setup display to go off after 1 minute.
Run any gui app (PHPStorm in my case). Lock your PC (wait 1 minute).
Expected behavior
Display should go off after specified time when WSLg app is running.
Actual behavior
Display won't go off.
If I can provide any logs that might help troubleshoot - happy to do so.

I have the same issue. Looks like rdp is blocking sleep. Don't know how to fix it though.

Thanks for reporting, currently the default idle timeout in WSLg is 300 seconds (instead of 60 seconds you may configure in Windows Settings app), would you please check if display turned off after 300 seconds of idle time? We are looking a way to sync display timeout between Windows and Linux side.
If it doesn't turn off display after 300 seconds of idle time, it is possible that those application update UI at least once within every 300 seconds, currently WSLg is configured to keep display awake as long as they updates their UI. This makes weston compositor never enter idle state and it blocks display to be turned off at Windows side.
You can check if display timeout is actually blocked by WSLg by running "powercfg -requests" command from command prompts on Windows and check if mstsc.exe has reference to DISPLAY.
Thanks!

fliespl , I tried PhpStorm and it looks this app is blinking caret by default, and it doesn't stop even after long period of idle, this is causing compositor to keep awake. If you can move focus out of the editor pane (by clicking project pane, for example), this makes caret at editor pane no longer blinking, then I confirmed that display can be turned off after 300 seconds. Also you can uncheck caret blinking at settings as workaround (below screenshot).
geneing , what application are you running and encounter this issue?

Hideyuki Nagase (@hideyukn88) yes I can confirm it was showing mstsc.exe during my problems, which lead me to RDP and idea it's connected with WSL.
Strange thing is:
Gonna give it a try with caret later today and report results tomorrow - thanks! If disabling caret would fix the issue - should I report this bug on jetbrains or is it more WSLg related somehow (or maybe neither / both)?
geneing commentedon May 10, 2021
Hideyuki Nagase (@hideyukn88) The interesting thing is that rdp keeps the screen up even when I'm not running any Linux gui applications. I usually run VS Code in win10 with WSL2 remote and a console application in WSL2.
Is there a simple way to see which weston clients are running in wsl2?
hideyukn88 commentedon May 10, 2021
geneing , please check which version of WSLg you are running? There was such issue in our very first insider release of WSLg, but fixed in following release, please check if you are using 1.0.19. You can find the version of WSLg is at /mnt/wslg/versions.txt. Thanks!

Hideyuki Nagase (@hideyukn88) Here's the output of cat versions:
I ran wsl --update, and this is the latest version.
fliespl commentedon May 11, 2021
geneing you must install msi/exe from the releases in this repo https://github.com/microsoft/wslg/releases/tag/v1.0.20
Hideyuki Nagase (@hideyukn88) unfortunately disabling caret made no difference to my case. Display still didn't go into off mode.
What's more important. After closing phpstorm it didn't went to off mode as well, cause powercfg still reported that rdp has display access. Closing with wsl --shutdown resolved it and display went off.
powercfg -requests
DISPLAY:
[PROCESS] \Device\HarddiskVolume3\Windows\System32\mstsc.exe
RAIL Power Request

fliespl Hideyuki Nagase (@hideyukn88) Installing updated msi solved the my display sleep mode issue. It would be great if information about updating wslg was available in the README.md
hideyukn88 commentedon May 13, 2021
geneing , thanks for feedback, first, we note major fixes for each release at release page (https://github.com/microsoft/wslg/releases) and this particular fix should have listed there, but somehow didn't make it. For reference, this issue was fixed by this commit : microsoft/weston-mirror@febf611.
Regarding to updating wslg, README.md has a section, https://github.com/microsoft/wslg#updating-wsl--wslg, if any are not clear or not sufficient, please suggest us, thanks!
fliespl commentedon May 13, 2021
Hideyuki Nagase (@hideyukn88) i think this issue is far from closing ;) caret didn't make difference in my case (see above).
hideyukn88 commentedon May 13, 2021
fliespl , thanks for pointing out that, sorry I missed that. Since there could be various settings in PhpStrom, so I won't go into why it's not powering off while PhpStrom is running, first, but clearly it should go off after you close PnpStorm (and wait 5 mins). So please allow me to double check basics, do you wait at least 5 or more minutes to check by "powercfg" ? and check if there is any hidden GUI applications running by accident? please check by "ps -axf". For X apps, you can do "xwininfo -root -tree" to see if any outstanding window opened, (and for Wayland native, unless debug is enabled, we can't get scene-graph. while there is a way to enable debug, but hopefully ps will give clue if any is running), thanks!

FYI - This is also in effect on Windows 11.
This is what I found using Sysexplorer (internal tool)
mstsc.exe /v:AE94C869-A9B3-43E2-A2C0-DF94E8EE24C2 /hvsocketserviceid:94F99ED2-FACB-11E6-BD58-64006A7986D3 /silent /wslg /plugin:WSLDVC /wslgsharedmemorypath:WSL\AE94C869-A9B3-43E2-A2C0-DF94E8EE24C2\wslg C:\ProgramData\Microsoft\WSL\wslg.rdp
IF anyone found a solution for that, I'd appreciate it
Thanks!

really annoying

Dennis (@erSitzt), would you please share /mnt/wslg/weston.log and /mnt/wslg/stderr.txt? And please double check WSLg is up to date from aka.ms/wslstorepage. Thanks!

Here is how I fixed my monitors not going to sleep on a new build of Windows 11 with WSL (specifically in locked mode).
powercfg /requests
DISPLAY:
[PROCESS] \Device\HarddiskVolume1\Windows\System32\mstsc.exe
RAIL Power Request
SYSTEM:
[PROCESS] \Device\HarddiskVolume1\Windows\System32\mstsc.exe
RAIL Power Request
These processes appear three times for me (assuming one for each monitor as I have three).
The fix for me:
powercfg /requestsoverride PROCESS mstsc.exe DISPLAY SYSTEM
What we are doing here is overriding the caller type (PROCESS) with the name of the process (mstsc.exe) and the request/s in this instance requests being (DISPLAY) and (SYSTEM).
After this adjustment regardless if these processes were shown as requests, my monitors would successfully go into sleep mode.
Hope it works for you too, good luck!
For more info on the power configuration option and its parameter list:
powercfg /requestsoverride /?
hideyukn88 commentedon Apr 2, 2022
creativestate, it looks you are on older version of WSLg, and the "monitor not getting sleep" issue should be fixed in newer release. Please install WSL/WSLg from aka.ms/wslstorepage, thanks!
g2flyer commentedon Aug 1, 2022
Hmm, i just installed latest version of WSL/WSLg last week and i still had the issue (but could solve if using the requestsoverride mentioned above ...)
PS: oops, just realized that i have the latest wslg and the latest of wsl you get with windows. However, i do not have the wsl preview from store, which creativestate refers to. my bad ...

(Windows 11)
After updating to the app store preview version of WSL, the RAIL Power request now comes from msrdc.exe instead of mstsc.exe.
Is this expected?
Installed from app store -
/mnt/wlg/versions.txtshows the following.WSLg ( x86_64 ): 1.0.42+Branch.main.Sha.78fa15d6ffd8fad62343b194d39c142e57cc1869powercfg -requests:EDIT: Seems to have disappeared now.

Yes, it is expected. We moved from Windows OS inbox

Now msrdc.exe keeps my system awake, no idea how to change that behaviour
