Before, I had problems installing the a200 intel wifi/bluetooth driver which I didn't manage to install properly (I had downloaded it but couldnt use it - I didn't get it running). Then I installed instead blueman, dkms etc and got an internal error message. I de installed all that and the internal error message is also gone, but I still get this message when booting.
In the progress, I also edited via vim that "compress gzip" but that didn't help.
I also had entered
/etc/modules over vim but I am not sure whether I did that correctly.
Nonetheless, I de installed blueman, blueman manager and dkms but I am still left with that error message shown above, that had not been there before I started to fix my bluetooth problems.
Maybe you can help? (BTW, kernel is 5.4)
sudo update-initramfs -c -k $(uname -r). Reboot. Report back.
compress gzipback to default? If not, do so, and redo the update-initramfs command. Also, your edit of /etc/modules with rtbth is probably incorrect, and that's probably why bluetooth doesn't work. What is rtbth? What dkms driver had you tried to install? What bluetooth driver had you tried to install?
