Description Tony Narlock 2015-09-15 02:41:25 UTC
When booting, the "font size" / resolution / modesetting is large and there isn't much space. When entering X and quitting X, (going back into terminal), the vty font-size is perfectly adjusted to the resolution. I'd like it to boot that way.

Is this behavior by design or a bug? What more information can I provide?

This is the expected behaviour when your system boots in VGA mode. In that case vt(4) starts as 640x480. Once your video driver loads it switches to the native screen resolution.

You can load the i915 driver from the command line to switch to the higher resolution, or try loading i915kms.ko from the loader.

Also if you boot via UEFI instead the vt_efifb driver will be used instead of the vt_vga driver, and will likely run at the native resolution.

I'll leave this PR open pending the creation of useful documentation on configuring this.
