How can I detect when a monitor is plugged in or unplugged?
Is there any event that is triggered when I plug in or out an external monitor into the DisplayPort of my laptop? ACPID and UDEV don’t react at all.

Udev rule to mount disk does not work
I have the following content in in /etc/udev/rules.d/81-external-disk.rules:
Why is my udev-fired script not working?
I created a udev rule in order to sync my USB drive with my documents folder, but it doesn’t seem to be working.
Udev rules for seemingly indistinguishable devices
I’m trying to use udev to automatically set up symlinks to an Intel RealSense D415. This is because I use several cameras on the machine and need to be able to reliably refer to them via a filename (that doesn’t change on reboot).
How to assign USB driver to device
This question is two-fold:
How does the linux kernel know device major and minor numbers?
As far as I know, the kernel detects hardware, adds information to sysfs creates a device in /dev and then generates a udev event. My question is, do device drivers do all of this or it is the kernel itself? If drivers do it, then they would know the device major and minor number to create the file in devtmps.
USB flash drives automatically mounted (headless computer)
For the project SamplerBox, up to now I was using /dev/sda1 /media auto nofail 0 0 to have USB flash drives automatically mounted when inserted on the headless computer, see also Auto-mount and auto-remount with /etc/fstab. But this seems not very reliable, for example, when an USB flash drive is removed, and then re-inserted.
Udev : renaming my network interface
I just installed RHEL 6.3 on a Dell 1950 server.
This server as two GBit ports, Gb0 and Gb1.
How to disable USB devices based on their vendor ID on GNU/Linux?
In that question someone wanted a blacklist for all USB devices, and then only allow specific devices.
udev rule for assigning known symlinks for identical usb serial devices
I have two (and possibly in the future, more) USB serial devices which are identical (down to the serial number, unfortunately) – they’re actually BTC miners. Currently they end up as ttyUSBX where X is 0, 1 or 2, as there’s another unrelated USB serial device as well (which need not be worried about here).
