I'm considering buying a laptop with a hidpi screen, but am unsure how good things will look. I'd like to run XFCE or gnome flashback on it, but would like a way to test things before spending $2k. Is there a way (perhaps with a VM or something) I can test on non hidpi hardware to know if things will scale properly on the real thing?
You can specify the virtual screen size in
Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Virtual 3600 1200 EndSubSection EndSection
