Screen adjustment

[moonwalkers]

Yes but the problem is everywhere, not just in Xfree86.  It was one of my apprehensions before buying, putting that much resolution in that small an area.  I spend most of my time in rxvt and joe and mc where font sizes are measured in pixels like 6x10 or 9x15, not how many points (1/72 inches) they take up on the screen.  I have an alias that starts rxvt at the largest font size.  And sometimes it's fun in an odd way to not be in GUI mode at all but with my normal reading glasses it's a challenge just to log in.

I was sort of hoping someone would chime in and say sure, you can change the resolution in extlinux.conf, or no, it won't work and save me the experiment.  I don't remember if the Rock64 and PBP are at all the same there.

XFree86 hasn't been in widespread use since shortly after X.org was forked from it.
The high resolution in a small package is fine if you don't insist yourself and don't have someone else that insists for you on using some older software that doesn't deal with scaling well. I've been running Linux on a screen with more than 200 dots per inch since late 2013 or whenever ThinkPad W540 came out, with its 2880x1620 on a 15.6" screen, and the only time I had issues was when I had to run some Adobe Flash or Java applets.
joe and mc use whatever font the terminal emulator is using, and rxvt... Well, it's not completely hopeless, but it is certainly less flexible than some newer terminal emulators like Konsole (my personal preference). If you don't feel like trying something new you should still be able to run rxvt like so:

Code:

rxvt -fn "xft:Monospace:pixelsize=24"

Now, this will launch it using FreeType font rendering, with whichever font is aliased to Monospace on your system, with size of 24 pixels. You can easily change the font name--see output of `fc-list`--and you can easily increase the size by increasing the number of pixels to render the font onto.

As to your screenshot - it's Openbox, no? It's been a long while since I touched Openbox (or the full blown LXDE, for that matter), but IIRC you should still be able to change the fonts for the whole environment in one place, and most applications will obey.
