Felix,

I was not able to find out how to add a parameter during the boot process.  

I put the video=1920x1080@60 in the 'default' line, update-grub, update-grub2 and rebooted.  There was no change.  

Followup for previous typo:
While the shell command had the correct designation '1920', I found file names using '1960'.  I changed all of them and rebooted, no change.  

Also have:
~/.config/autostart# cat lxrandr-autostart.desktop
[Desktop Entry]
Type=Application
Name=LXRandR autostart
Comment=Start xrandr with settings done in LXRandR
Exec=sh -c 'xrandr --output eDP1 --mode 1920x1080'
OnlyShowIn=LXDE

During a Xfce session, I changed the DPI from 96 to 300 and did not observe any difference in the display.  I am wondering if my expectations are misaligned.  Reading Xfce 'How toos', I see many descriptions where people build a disktop widget to click to change settings as if they have not implemented an automated method - which I prefer.
