I don't see how it can be called great. This is pretty much losing most |
25 |
of the benefits you have with a HiDPI screen, by just making it be |
26 |
almost the same as a 1600x900 screen, except the scaling involves some |
27 |
nearest neighbor filtering, which sometimes might be good, sometimes |
28 |
bad, and never as good as rendering things in HiDPI. |
29 |
|
30 |
For HiDPI you want the toolkit to support it properly and configure it |
31 |
as such. GTK+3 is such a toolkit, but outside of GNOME (where it works |
32 |
out of the box), I don't know what exactly it takes to set things up. |
33 |
Plus you'll need a solution for your gtk2/whatever other things, |
34 |
preferably one that doesn't make things worse for gtk3 things, like |
35 |
that xrandr hack does. |
36 |
|
37 |
Probably something like |
38 |
gsettings set org.gnome.desktop.interface scaling-factor 2 |
39 |
combined with something for the other stuff that doesn't mess with the |
40 |
former. |
41 |
Outside GNOME, maybe exporting GDK_SCALE=2 works, if the dconf setting |
42 |
isn't honored outside it. |
