I just want to run (as root) a command or script before each reboot/shutdown/poweroff on Ubuntu 21.04 (when I run the shutdown or poweroff commands, or using GNOME/KDE GUI options). I've tried putting the script inside /etc/init.d and making symlinks to /etc/rc6.d/ and /etc/rc0.d/ but doesn't work.
Wonder if there's such a line for sudo crontab -e.
I want to run this script on ubuntu 19.04, after booting the OS to restore the previous screen brightness:
echo 50 > /sys/class/backlight/nvidia_0/brightness
How can I run this script so it takes effect at the right moment?
I want to execute a script when I click on Reboot or Shutdown, but just before anything, so all filesystems are still mounted, like if I entered the command on Terminal, when the operating system is still running. OS is Ubuntu 19.04
Running ubuntu 18.04 with nvidia-driver-390. How can I switch to nouveau and make the change persistent between reboots?
have my ubuntu 18.04 booting in MBR mode. How can I convert it to boot UEFI with Secure Boot without having to reinstall it?
Is there some application to graphically view which partitions are mounted and be able to unmount them from the GUI? Like on Windows -> My Computer -> Eject.
I would like to know how to set the minimum and maximum cpu state on ubuntu, like you do on Windows 10 on power settings. Just a way to control the MIPS and prevent CPU overheating when the thermal paste is a little bit worn out:
I need to shrink the root partition to give more size to the boot partition. Can I resize/shrink the root lvm2 partition while using it from inside ubuntu?
