I tried installing a couple different kernel versions, but none of them seem to even recognize my second monitor except the one currently running. I can only imagine that there is something else wrong, as well, since I feel sure that these kernels _used_ to at least detect the second monitor.
If you have another suggestion, I'll try that, and if not, maybe I'll try the "system refresh" style OS re-install; if I can figure out how to do that with disk encryption ... # Instructions ## Installs and Changes ### Mainline Kernel Helper ```sh sudo add-apt-repository ppa:cappelikan/ppa sudo apt update sudo apt install mainline ``` ### Show Grub Menu ```sh sudo nano /etc/default/grub ``` ```sh GRUB_TIMEOUT_STYLE=menu GRUB_TIMEOUT=5 ``` ```sh sudo update-grub sudo reboot now ``` ### Install Old Mainline Kernel #### Attempt 1 ```sh sudo mainline install 6.8 ``` Result: secondary monitor does not work at all. #### Attempt 2 ```sh sudo mainline install 6.8.4 ``` Result: secondary monitor does not work at all. #### Attempt 3 ```sh sudo mainline install 6.0 ``` Result: refuses to boot at all. #### Attempt 4 ```sh sudo mainline install-latest # 6.13.4 ``` Result: secondary monitor does not work at all.

Put the laptop to sleep (via suspend) 2. Attempt to wake it. 3. Screen remains black, and requires hard shutdown to regain control. **Workaround** 1. Turn off the external monitor via meta+P (and select built-in only) 2. Suspend and resume works just fine.
