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.
