Triggering an action when a specific volume is connected
I have a USB key that contains my keepass2 password database and I’d like to perform some actions when it is plugged into my computer, namely:
ubuntu
Howto find my xorg.conf. Where is it?
I can’t find my xorg.conf.
Cannot remove file: “Structure needs cleaning”
I have an external hard drive which is encrypted via LUKS. It contains an ext4 fs.
Installing two glibc alongside in debian/ubuntu
Is it possible to install and use two different glibc versions on the same machine. Where one version is only used to run legacy software, which relies on old glibc binaries?
How do I migrate configuration between computers with different hardware?
I want to migrate the configuration of an Ubuntu desktop to a new box with different hardware. What is the easiest way to do this? /etc/ contains machine and hardware specific settings so I can’t just copy it blindly. A similar problem exists for installed packages.
Finding files that use the most disk space
Is it possible to list the largest files on my hard drive? I frequently use df -H to display my disk usage, but this only gives the percentage full, GBs remaining, etc.
How do I make my laptop sleep when it reaches some low battery threshold?
I’m using Ubuntu, but I have i3 as my window manager instead of a desktop environment.
Why won’t my xmodmap command run on startup/login?
I want to run this command every time I log in (or every time I start up, if that doesn’t work): xmodmap -e 'keysym Delete = Menu' -e 'keysym Menu = Delete'
Why is screen seemingly doing nothing with commands passed with -X?
I’ve been trying to set up an automated backup system for a minecraft server, and I’m having trouble with screen, specifically when using ‘screen -r sessionname -X “/var/minecraft/somebatchfile”‘, nothing happens.
What is the “/usr/local/src” folder meant for?
I wanted to put my work files (code) in /usr/local/src, but I think it’s already a folder that has some other semantic meaning.
