I have been getting lost looking at problems with the nVidia driver. Before updating the kernel I was using a PPA for the driver: https://launchpad.net/~kelebek333/+archive/ubuntu/nvidia-legacy
This is apparently not supported for the new kernel: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1916640
Do I revert to an earlier kernel? If so, how (I am a novice, and also rusty)?
Do I go ahead to a newer kernel, not yet supported? https://github.com/MeowIce/nvidia-legacy/tree/340.108
Or perhaps there is a way to work around it with changes to brightness controls, which is discussed in forums?
Update
This seems to have been solved, by installing an earlier kernel which works with the nvidia driver PPA. Still interested to hear other solutions/advice. For other novices I will list the steps I took and links which I found helpful:
Check PPA bug post about latest version of kernel for which driver works: 5.17.x https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1916640
Download kernel files https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17.15/
Install kernel
sudo dpkg -i *.debhttps://askubuntu.com/a/700221/1143711Check GRUB menu:
sudo grub-mkconfig | grep -iE "menuentry 'Ubuntu, with Linux" | awk '{print i++ " : "$1, $2, $3, $4, $5, $6, $7}'Old kernel is shown on menu.Follow the instructions of Yuri Sucupira ('long answer') to change grub settings. This allows access to the grub menu on the Mac: https://askubuntu.com/a/1299955/1143711
Reboot. Select Advanced option from menu, then select kernel 5.17 from menu.
Install PPA for nvidia-legacy driver
sudo apt install xorg-modulepath-fix
