Thanks for response. Using similar method to start, with full path
pointing to handler, I am getting script called and it does what is
intended... but I have just
---- 8< ------------------------------------------------------------
#! /bin/sh
/usr/bin/env>/home/milan/randr-log-env
---- 8< ------------------------------------------------------------
in my script, so nothing is currently done, just logged.
The main problem, however, still remains - action is done not when
cable is being plugged/unplugged, but xrandr or arandr must be called
manually, then intended action occurs.
What hardware do you have? In my case, graphics device is
---- 8< ------------------------------------------------------------
vgapci0@pci0:0:2:0: class=0x030000 rev=0x06 hdr=0x00 vendor=0x8086 device=0x3185 subvendor=0x0000 subdevice=0x0000
vendor = 'Intel Corporation'
device = 'GeminiLake [UHD Graphics 600]'
class = display
subclass = VGA
---- 8< ------------------------------------------------------------
and kernel driver used is i915kms.ko.

Milan
