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.

Go ahead and report it to the Mint team. Even if it is an issue upstream, they will verify the issue and then report it as well. Never hesitate to report a bug you find, especially if it's a security or privacy issue.

Even if the bug is a duplicate, it helps to know other people are having the same issue. At worst they will mark your report as a duplicate, which will let you know they are aware of the issue.

Keep in mind that if it is a serious security issue many projects have a way of reporting them separately from other bug reports so the issues can be patched before being published.

This is a known Xorg issue. Distros like TAILS have patches (can't find a source right now, but it was probably 6+ years ago). The solution is Wayland, since despite TAILS fixing it, no one else seems to have bothered.

(I have the same problem on Fedora 40 XFCE)

This shit right here is why you absolutely must use xscreensaver.

Not some repackaging of the hacks.

Not some implementation with your wms decorations.

Xscreensaver.

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.
