On: GWSL: Run graphical Linux apps in WSL

For me it really helped to copy and paste the commands related to the X server.

For instance I had a small issue with the scale of the applications. In Windows I have 250% (recommended) scaling applied.

``` export QT_SCALE_FACTOR=2.5

export GDK_SCALE=$(echo "(${QT_SCALE_FACTOR} + 0.49) / 1" | bc) #Round ```
