usability enhancements inside virtual machines

Sets environment variable QMLSCENE_DEVICE=softwarecontext as workaround for "Automatic fallback to softwarecontext renderer".

It is not useful to open a screensaver or to power down the desktop for operating systems that are run inside VMs. There is no real display that could be saved and no real power that could be saved. From usability perspective it also is counter intuitive when looking at the VM window and only seeing a black screen. Therefore it makes sense to disable power savings in VMs. /etc/X11/Xsession.d/20_kde_screen_locker_disable_in_vms.sh /etc/profile.d/20_power_savings_disable_in_vms.sh /etc/X11/Xsession.d/20_software_rendering_in_vms.sh /usr/share/kde-power-savings-disable-in-vms/kdedrc /usr/share/kde-screen-locker-disable-in-vms/kscreenlockerrc

Disables screen locker when running in VMs because that is not useful either.

Makes setting up a shared folder for virtual machines a bit easier.

• Creates a folder /mnt/shared with chmod 777, adds a group "vboxsf", adds user "user" to group "vboxsf". Facilitates auto-mounting of shared folders.

• Helps using shared folders with VirtualBox and KVM a bit easier (as in requiring fewer manual steps from the user).

• /lib/systemd/system/mnt-shared-vbox.service

• /lib/systemd/system/mnt-shared-kvm.service

Set screen resolution 1920x1080 by default for VM in VirtualBox and KVM. Workaround for low screen resolution 1024x768 at first boot. When using lower screen resolutions, Xfce will automatically scale down. /etc/skel/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml

Installs VirtualBox guest additions if package virtualbox-guest-additions-iso is installed if environment variable dist_build_virtualbox=true or if running inside VirtualBox. (systemd-detect-virt returning oracle) /usr/bin/vbox-guest-installer
