From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Found a security bug in LMDE6, need some help (i.imgur.com)

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.

Or Wayland, where this isn't an issue.

I like my security bugs well publicized with documented workarounds as opposed to undiscovered and undisclosed, thank you.

Apropos of nothing, Xscrensaver is my bellwether for moving to Wayland. When it’s officially ported I’ll switch.

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.
