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?
When I hold shift during startup and then go to advanced options and select the previous version it all goes back to normal but I need to do this manually every single time.
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.Just uninstall theatesy kernel packages and it will be gone from the Grub boot menu, or you can also manually set the default Grub version to boot very easily (guides and docs everywhere online).
