Bluetooth not working at all, internet not working at all, and even the setting for HDMI audio output is gone. The settings page is just empty.
I managed to load an older kernel(?) and got Bluetooth and internet working again, but still no audio. I’m as much of a novice at running Linux as you can get. I’ve been trying to troubleshoot this with the help of an LLM, but I have no idea what I’m doing here.
Any help, please?
If you want to make GRUB remember the last boot entry you picked, you can edit /etc/default/grub and set the following
(make note of the original values or comment out the existing entry by adding # to the start of the line first)
GRUB_SAVEDEFAULT=true GRUB_DEFAULT=savedthen run
sudo update-grubto apply the changes. When you next boot and select a kernel, GRUB will remember that choice and just use it.Maybe you could try reinstalling the newest kernel?
sudo tac /var/log/apt/history.log | lessshould give you a list of the last updates that were installed. Idk what Ubuntu calls their kernels, but they’d be packages named like “linux-image-generic” or something like that. If that doesn’t work, then maybe they messed something up on that kernel update and you’ve gotta wait for a fix.Whenever it does get fixed, you may want to undo the changes to /etc/default/grub
I did
GRUB_DEFAULT="1>2"instead so it now loads the previous version instead - I think. I can only hope it’s fixed for the next update then, but for now everything seems to work fine.
