Yes, it was not necessary to get down from the tree!
If you think that electromagnetic radiation does not harm human health, then you are very wrong.
Instead of Virtualbox, I suggest you use kvm. The Kernel Virtual Machine, or KVM, is a full virtualization solution for Linux on x86 (64-bit included) and ARM hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, which provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
If you are interested and want to try it, you will need the following packages:
sudo apt update
sudo apt install qemu-kvm libvirt-clients libvirt-daemon libvirt-daemon-system bridge-utils virtinst virt-manager
In order to manage virtual machines as a regular user, that user needs to be added to the libvirt group:
#adduser youruserrname libvirt
#adduser youruserrname libvirt-qemu
After installing and setting everything up, reboot your computer.
So the last line of your .xsession should just be:
exec /usr/bin/<WM>
Hello. Should not be
.xsession
but
.xsessionrc
The Debian reference manual describes how the defaults work:
If the user has a ~/.xsessionrc file, read it.
If a specific session was selected in the DM (GDM, KDM, WDM, LightDM, ...) , run it.Otherwise, if the user has a ~/.xsession or ~/.Xsession file, run it.
Otherwise, if the /usr/bin/x-session-manager command exists, run it.
Otherwise, if the /usr/bin/x-window-manager command exists, run it.
Otherwise, if the /usr/bin/x-terminal-emulator command exists, run it.
This file should be executable. Here is example of
.xsessionrc
#!/bin/bash
# Load resources
xrdb ~/.Xresources
setxkbmap -layout "us,lt,ru" -option "grp:menu_toggle"
picom --config ~/.config/picom/picom.conf &
exec xmonad
