**UPDATE 1/28/2022, 1500 PST**
I have edited the original posting to keep the description of the problem only in the body of the report. I have moved all the System Info outputs to attached comments below, as well as all the other output reports for the terminal commands I was recommended to execute.
The first/older set of automatic report outputs and info attached in the comments below are from terminal command outputs while running Linux Mint 20.3 with Cinnamon DE while I was still using kernel 5.11.0-46; they should probably be ignored (I'm unable to delete them). The second/newer set of automatic report outputs attached are from terminal command outputs while running Linux Mint 20.3 with Cinnamon DE on kernel 5.13.0-27. Sorry. I Told you I was new to this...
**End of text update**
Please accept my apologies up front for any inefficiencies this format may induce, as I'm a very casual user who has just started to scratch the surface of Linux distro usage. I have read the instructions on the report submission page and I believe I am following the guidance, but if I'm not it's because of unfamiliarity and general ignorance. I beg for your patience and understanding.
For the listed kernels in the summary line (kernels 5.13.0-21, -22, -23, -25, and -27), my Acer Swift 3 laptop's screen crashes/reverts to snow/white noise immediately whenever the following conditions are met:
1) Any video peripheral is connected to the laptop via the HDMI port directly or through a USB-C hub with HDMI input
AND
2) The "Mirror" selection is toggled in the Display Manager GUI
OR
3) The HDMI cable is removed from the HDMI port/USB-C hub
I can confirm that: 1) The HDMI cable is not the culprit because this issue doesn't manifest itself with Win10 or with Manjaro Linux, and 2) running Linux Mint 20.3 with the 5.11.0-46 kernel does not manifest any of the described screen crash issues listed above. That is to say, the laptop and peripheral HDMI display run stably/without issue while running Linux Mint 20.3 with Cinnamon DE on kernel 5.11.0-46.
Thanks. Please advise if I may be of any further assistance.
Very Respectfully,
John McGee

Thank you for taking the time to report this bug and helping to make Ubuntu better.
Please execute the following command only once, as it will automatically gather debugging information, in a terminal:
apport-collect 1959348
When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https:/
Please note: `ubuntu-bug`, `apport` & bug reporting tools are provided with Ubuntu by default, many require manual addition for some releases of downstream OSes based on Ubuntu (eg. Linux Mint). You should check with your distribution first.
Also note I've marked this as 'incomplete'. On completion of the `apport-collect` which will cause package & other details to populate fields in this report (currently empty), the status should be returned to "New". If you are unable to run these using the kernels that 'crash', you can use other recent kernels, but please note that via comment."
