# Fixing a frozen screen caused by systemd 256
|
||
|
|
|

Posted on Sat 03 August 2024 in [Technical](https://simongreenwood.me.uk/category/technical.html)

[Systemd version 256](https://github.com/systemd/systemd/releases/tag/v256) has been rolled out in several distributions recently, including Arch and Debian and variants. It adds a feature where user sessions are frozen when the system enters sleep, but in my case, running Manjaro Linux with KDE on a Gen 1 Lenovo T14, this meant that when the system woke, the screen remained frozen and required a reboot by switching to the command line with `Ctrl-Alt-F3`.
|
||
|
|
|
||
|
|
At first I perhaps unfairly assumed that this was KDE as it affected the desktop but left the mouse working and indeed the system accessible with through the console, but after a bit of digging around in the system journal with `journalctl -b-1 -p4 --no-pager` (a really useful command that I didn't know before), I found the error `Cannot start frozen unit Session 10 of User xxxxx` from systemd.
|
||
|
|
|
||
|
|
Searching on that brought up the problem and conclusively pointed at the 256 update, and a solution, or at least a fix until the issue is fixed.
|
||
|
|
|
||
|
|
The fix is to add an override to the `systemd-suspend` service. This doesn't actually have a service file in `/etc/systemd/system` in Manjaro at least, so you need to create the directory `/etc/systemd/system/systemd-suspend.service.d` and create an override file called `disable_freeze_user_session.conf` with these contents:
|
||
|
|
|
||
|
|
```
|
||
|
|
[Service]
|
||
|
|
Environment="SYSTEMD_SLEEP_FREEZE_USER_SESSIONS=false"
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
Save this, and restart systemd with `systemctl daemon-reload`.
|
||
|
|
|
||
|
|
This disables user freeze on sleep and for me at least, reverted to the previous behaviour. I found that a lot of the examples mentioned Nvidia video hardware, which I don't have, so it's probably a wider issue than I've found.

I've added a comment to the [Github issue](https://github.com/systemd/systemd/issues/33083).
