Problema con 2º. monitor después de actualizar núcleo

done… but no changes

try installing the 5.10 kernel then, and try with it:
sudo mhwd-kernel -i linux510
then reboot and boot into it and check with uname -a if youre running it

5.10 kernel installed but no changes

then log out, and in the login screen press ctrl + alt + f2 instead of entering your password, youll enter into TTY and in here uninstall the nvidia drivers:
sudo mhwd -r pci video-nvidia
reboot with this:
systemctl reboot

I have logged out, then logged in and pressed ctrl+alt+f2 but nothing happens

no, dont log in again, just log out and enter into tty by pressing ctrl + alt + f2 … and run those 2 commands above

Sorry, I meant that I logged out and then pressed ctrl+alt+f2 but nothing happened.

then try pressing these buttons ctrl+alt+f3, if f3 doesnt work try f4, f5, f6… some of them will work, then enter your name and your password and then those commands

done, but then appears an error: “video-nvidia is not installed”

so youre not having nvidia drivers installed, post output:
mhwd -li

so enter again into tty - ctrl+alt+f3, and try running this:
sudo mhwd -r pci video-hybrid-intel-nvidia-prime
then reboot:
systemctl reboot

it works!! many thanks for your time, Brahma. I appreciate it.

Now I must install anything else? May I install latest kernel?

wait… now go to system settings/ manjaro settings/ hardware configuration and select autoinstall proprietary drivers - check for errors in the dialog windows, if everyhing went ok, reboot and check if the displays are detected

Done, and everything seems to work ok.

Many thanks, again.

just to be sure that every driver is installed post the output of:
mhwd -li

Wait for your news.

everyhing looks ok, now you can change kernels if you want

gonna check it out

Just a question: the correct procedure to install a new kernel is 1) install new kernel, 2) uninstall old kernel and 3) reboot???
