I am trying to change DPI scaling for Whonix Workstation on Qubes OS. Therefore I used the templateVM and first changed /etc/xdg/Xresources (added Xft.dpi: 288) but this did not change anything. Then I changed /etc/xdg/xsettingsd (added Xft/DPI 294912) but this also did not change anything. To test these new settings I started a disposable Whonix Workstation AppVM. The scaling did not change, but I could verify my values in Xresources and xsettingsd on the started disposable Whonix Workstation AppVM.
Do you have an idea how I can change the scaling for Whonix Workstation templateVM so that it takes effect?
The target is to have an improved appearance of Tor browser (Whonix Workstation disposable AppVM) on a HiDPI display without affecting anonymity. Because changing window size or zoom level of Tor browser after it is started would have an impact to anonymity as far as I know.
