I've gotten to the root of the oversized (seemingly) font size when booting from UEFI: efifb is used by default. By adding
to kernel command line, everything looks and works as I had seen when booting the 32 bit iso (very clear and visually pleasing font rendering, indeed).
As a side note, the other issue that I noticed with unresponsive keyboard is transient and no doubt another symptom of this mainboard's buggy bios,
or maybe the kvm switch I have between this machine and my local rsync server is also a problem. Either way, I think it is good to be aware of this
type of issue, but not necessary for slint to "fix".
I am going to make room on one of this machine's hdds and give slint a full trial. Thanks for all your efforts. I'm impressed by the results.
Which wiki system are you using for your homepage? I like the layout. I looked at the page source, but either I missed it or it's not mentioned.
I'd like to use something similar on my lan's webserver.
