Recently I installed Deepin Beta 20 on a laptop with a resolution of 1366x768. I managed to upscale the resolution with the XRandR tool by using xrandr --output eDP-1 --scale 1.40556x1.40625 and adjusting the scaling option in the Display settings from 1.25 back to 1.0. This all works fine on the Beta 20 version, however I missed the controlpanel comming from the right side of the screen and the centered dock.
I decided to install Deepin 15.11 on the laptop and do the same trick with XRandR, this leads to a virtual border for the mouse to move and the dock somehere at a quadrant of the screen (restricted to the old 1366x768 resolutiion). I managed to get the mouse out of the virtual borders by adding options --fb 1920x180 and --panning 1920x1080 however I'm unable to get the dock in the right position. At the native resolution 1366x768 it sits correctly in the center of the desktop. But when I use the virtual resolution the desktop is scaled to 1920x1080 but the dock maintains the position of a 1366x768 so it blocks my applications. It seems to be unable to move the dock to the correct display position.
Commands used on Deepin Beta 20
xrandr --output eDP-1 --scale 1.40556x1.40625
Commands used on Deeping 15.11
xrandr --output eDP-1 --fb 1920x1080 --panning 1920x1080 --scale 1.40556x1.40625
