There seems to be no mention of Gnome (version, etc.) in your inxi output, which in itself is rather unusual. This leads me to believe that the update might not have successfully completed.
These questions are to help get a feel for what may have contributed:
- How did you perform the update; that is, which exact command(s) did you use?
- Did you update from within Gnome, or logout and use a TTY?
- Is any software installed via the AUR?
The following Tutorial shows how to enter a chroot environment, allowing you to perform various actions as the Super User (root).
You would need to boot with the Manjaro Installer USB, and use its Terminal. As you are using the ext4 filesystem, you can use manjaro-chroot -a to enter the chroot environment.
In the chroot environment, you are already the Super User, so sudo is not required for any command.
Try performing the update again:
1. Refresh the mirrors
pacman-mirrors --continent
2. Update packages from the Manjaro repo(s):
pacman -Syu
3. Build/update software sourced via the AUR:
pamac update --aur(using pamac)
4. If you use flatpak containerised apps:
flatpak update
While in chroot it’s likely a good idea to also remove your ~/.cache directory:
rm -rf ~/.cache/*
It should normally be recreated progressively as you use the computer.
I might also suggest updating Grub after the update(s) have completed successfully – while still in the chroot environment – it might be enough to use the install-grub script followed by update-grub (to update the configuration).
install-grubitself may need to be installed first:pacman -S install-grub
