I'm using Ubuntu 18.04 LTS on a Dell XPS 9570. Every time I plug my headphones in my laptop I get this annoying pop-up that blocks the entire desktop until I select an option. It's very annoying.
How can I disable it? I cannot believe that in 2019 I need to specify the audio device every time I plug the headphones.
When I first started using Ubuntu, I think my CD drives were mapped through /dev/cdrom0 and /dev/cdrom1, etc. but looking at things today, you can see they now come through on a sr prefix:
$ ll /dev/{cdrom,sr*}
lrwxrwxrwx 1 root root 3 Feb 10 09:15 /dev/cdrom -> sr0
brw-rw----+ 1 root cdrom 11, 0 Feb 10 09:15 /dev/sr0
brw-rw----+ 1 root cdrom 11, 1 Mar 27 10:30 /dev/sr1
I'm just curious what this stands for. TLDP isn't being very helpful here; and it still lists sd as "SCSI drive", and I think it more commonly means "serial drive" these days.
What does "sr" stand for? Why does /dev/cdrom still exist?
I connect my iPod and iPad to my computer to charge them. I do not want them to automatically mount on the desktop.
How can I keep using my computers many USB ports for charging without being bothered by auto-mounted devices?
I have USB device, which is actually identified as serial device by Ubuntu 10.04. How can I find its full path?
ls -la /dev/
shows a lot of devices. How to choose correct one?
How to rebuild /dev/ on an Ubuntu lucid where everything in /dev/ were accidentally deleted?
MAKEDEV std and MAKEDEV pty aren't enough, which isn't surprising on a system using udev.
I haven't rebooted yet because I fear I would lose access to my system.
