High DPI screen: "video=AAAxBBB" option not working in installer.


I've recently upgraded to a new laptop with a high DPI screen. Being a brand new laptop, I decided to install Slackware64-current on it, in a dual boot setup with W10 [needed for work, unfortunately].

After installation, I can append "video=1368x768" to the kernel command in elilo.conf and it will boot to [what I would call] a normal size console.

The Slackware installer don't seem to take this option, so I'm stuck using a magnifying glass trying to read the tiny fonts to complete the installation.

The odd thing is that the huge.s kernel which is used by the installer takes this option, so my thought is that there must be something missing from the initrd for the installer. I extracted the initrd, and noticed that the fbdev drivers are not in there under /lib/modules. Could this be the problem?

What if you append nomodeset while booting the Slackware Installation source?

It doesn't help.

The screen is a 15.6" LCD panel with a native resolution of 3840x2160.

The fonts are readable, but you've gotta get close... A magnifying glass helps.

The Slackware installer uses a fixed size font (that slightly differ whether you use or not a framebuffer)

In Slint 14.1 I had modified the installer to use fbterm and automatically adapt the font size to the screen's resolution. Maybe I will do something like that in Slint 15.0, we'll see. For now you do need the magnifying glass, and I am not sure Pat will want to modify the installer for that in Slackware 15. Maybe ask in this thread.

usable console font on hi-dpi:

Code:
$ cat /etc/rc.d/rc.font
#!/bin/sh
#
# This selects your default screen font from among the ones in
# /usr/share/kbd/consolefonts.
#
setfont -v ter-128b.psf.gz

Yes, I think the previous largest font included in the kernel was the sun-22 one, and that looked so bad no-one would want to use it.

Terminus-32 will give me a 85x24 display on my laptops 1366x768 100dpi console. It's a bit large (I normally use terminus-20, or 22) but it'll do for early-boot until setfont gets a chance to run.
