I do not want to lose the laptop in this isolationist environment. I have a different question, and that is, that the laptop has a HiDPI screen so needed tweaks to .Xresources to get it to display in a readable way. However, this is not needed for the attached monitor so is it possible to set things up so that the laptop screen scales things differently from the monitor? I have the following in my .Xresources for the laptop screen. !-------------------------------------------- ! Custom DPI !-------------------------------------------- ! Xft.dpi: 192 Xft.autohint: 0 Xft.lcdfilter: lcddefault Xft.hintstyle: hintslight Xft.hinting: true Xft.antialias: 1 Xft.rgba: rgb Xcursor.size: 32 --------------------------------- Which looks fine on my laptop but things look fuzzier on the monitor. How do I get this to be higher resolution for the monitor and it to also work on the HiDPI screen? I use openbox as my WM (and do not use a DE).
