I have an older Intel laptop that has a 1600x900 display, and I find that if I put the machine to sleep, connect an external monitor with a higher resolution, and then turn it back on, the login screen doesn’t adjust to the new resolution and it reveals what I had open (see photo).
However, I’m not that familiar with Linux Mint (even though I’ve daily driven Linux for nearly 10 years, I very casually use LMDE) and I’m not sure if this is a Cinnamon problem or if the lock screen is under a different program.
Looking at Linux Mint’s webpage on reporting a bug (https://projects.linuxmint.com/reporting-an-issue.html) they seem to mostly use Cinnamon as an example, but I don’t want to report this issue as a Cinnamon issue if it’s the wrong project.
In case this is platform specific, my device’s details are below:
- Host: Dell Latitude E6420
- CPU: Intel Core i7-2630QM (Sandy Bridge)
- GPU: Intel 2nd Generation Core Processor Family
- Kernel: 6.1.0-21-amd64
- DE: Cinnamon 6.0.4
- WM: Mutter (Muffin)
- Display Server: X11
I’ve never filed a bug report in my life before, usually I just put up with the issue until it’s eventually fixed, but I feel this is a moderate security issue that should be flagged.
I doubt there will ever be screensaver support with Wayland. Wayland isn’t a program so there is not a display server to connect to. The desktop draws directly to the screen.
Swaylock?
I mean, it absolutely could if stuff like ext_session_lock weren’t incredibly insecure.
There’s a thread on the maintainer of xscreensavers website that talks extensively about this and it got me trying to get just some stubs hooked into several wayland environments, seeing how the sausage is made and putting Wayland back on the shelf.
