[9front] figuring out what to add in vgadb?

[Jens Staal]

Hi all,

I am pretty happy with 9front on a cheap refurbished laptop, especially
now that ethernet over usb has been solved and I have built the latest
netsurf on it.

One little annoyance still is that I run at crappy resolution and can
not set it with aux/vga (and setting vgasize in plan9.ini did nothing)
Sysinfo can be seen here:
http://sysinfo.9front.org/src/542/body

Is there a similar trick to how usbtree could figure out what to do to
get nusb/ether to work but for graphics?

this entry from pci -v probably relevant but is there a way to translate
that to a vgadb entry?

Your card is a gemini lake gen igfx, which we unfortunately don't yet
support; our latest gen is broadwell, with work underway for skylake.
For now, vesa or the uefi framebuffer you're handed are the best you
could get.  An external monitor may work with vesa as well (see vga(8)
for example usage), but it's somewhat unlikely.

Hope that helps,

Thanks. Good to know that it is a driver issue and not "just" a
recognition issue (like nusb/ether). I will check if I can enhance it by
the UEFI framebuffer.

The resolution will be less of an issue when I got Sigrid's
riow/bar/theming set up. Especially having multiple work spaces will
definitely help.

a quick update: I could fix the resolution buy setting a higher
resolution in grub (dual booting 9front and Chimera Linux on this
machine). Could be good to know for people that do the same.
