How do you replicate Virtual Super Resolution on Debian based distro? Or like anything what would make GUI scale to make GUI more productive..
Thanks for any help (☞゚ヮ゚)☞
INFORMATIONS
This setup has one 1080p 60' monitor that is practically not useble to work with this scale for intended workload (Gaming, Audio-visual production, etc..)
Temporary GPU - ATI Sapphire 7870 AND AMD Radeon 7870
AMD has two names for this GPU as far as i know.
- Comparison in scaling W10 vs (X)ubuntu 18.04 (same device) - https://i.stack.imgur.com/mimrn.jpg
TRIED SOLUTIONS
Change font size
- Helped, but not much.
- I can scale fonts so that its practically unreadable, but GUI stays the same.
Change icon size
- Helped, but not much.
- Same as fonts, GUI is the same.
Switch from XFCE4 on KDE and change DPI for monitor in GUI
- Helped a lot, but still i need it to scale below “1”.
Modify xrandr for virtual resolution
- it seems to work, but screen can render just 1/4 at a time and the rest is accesable by moving cursor to the edge of the screen. Or it has black screen on ¾ of set screen which are non-useble.
- Tried command:
xrandr --output DVI-I-0 --mode 1920x1080 --fbmm 2560x1440 --nograb --rate 60
- Seems that 3D applications can’t use 2560x1440 and nothing changes. I try to find something usefull in man pages and i found command “--Transform”, but based on provided informations i don’t know how to use it and it seems that it doesn’t have intended effect.

Generate resolution using umc (Universal Moderline Calculator) and add it as mode to xrandr, then run it.
- Resulted in blackscreen same as cvr.
using "--scale" in xrandr allows me to replicate Virtual Super Resolution. (thanks to @Lienhart Woitok)
- The problem now is that i can't access that part of the screen with cursor, but apps seems to be able to.
- Testing different presets in xrandr now.

xrandr
has a scale option that might help you.xrandr --output DVI-I-0 --scale 0.5x0.5
orxrandr --output DVI-I-0 --scale 1.5x1.5
depending on which direction you want to scale.
