Qubes and HiDPI

[Marc de Bruin]

Lo,

To start with, I’ve read https://github.com/QubesOS/qubes-issues/issues/1951. 

I got this new Dell XPS 15 9550 with a HiDPI screen (3840x2160). I’ve been trying to get it working the way I want: native resolution with readable text. Xfce provides a way to increase the system font to 192dpi; KDE has a scale factor to increase all fonts with a factor. Either way, the Qubes VM Manager doesn’t seem to scale it’s own “graphics” accordingly, is that correct? E.g., displaying the column with the IP-addresses results in it only displaying “10.137.”. The rest is cut of, because the width of the column doesn’t seem to get wide enough.

Is there a way to get around this? Doesn't the Qubes VM Manager “window” proportionally scale itself related to the occupied pixels of the text due to the font? Or am I missing something?

Greetz,

Marc.

Agh, unfortunately no. Some layout is hard-coded.

I wanted to fix it, but no time, and whole qubes manager is due to be
replaced anyway.

Im missing something here, why not just set your screen res in dom0 to 1920x1080 or whatever you find comfortable?

i could see it useful for art or visualization. what other advantage would it have?

FWIW this is what I have done, and I don't mind it.

The not-quite-pixel-bound edges due to scaling are noticeable if you
are looking for them, but it doesn't bother me.

A positive effect of this is AppVMs have less pixels to render without
hardware acceleration, so lower resolutions are in some cases
noticeably more responsive.

I will do the same, no problem. I just couldn’t believe it didn’t rescale proportionally. It is the first thing you learn when programming GUIs I guess? ;-) Nevermind. Qubes rulezzz. With what will it be replaced in Qubes 4?

Thanks,

Greetz,
Marc.

Assuming you mean qubes-manager, then...

Because it is looking much better and for people spending more than 12
hours using a computer this makes a difference.

Ask your ophtalmologist.
