[9fans] xga or vesa?

[freeasinfreedom]

What are the pros and cons of using xga versus using vesa? Which xga
version does actually plan9 support (http://en.wikipedia.org/wiki/
Graphic_display_resolutions)?

In my case, both xga and vesa work, but when I tried to use xga with a
24 bit depth I got an error. What I actually care about is to find out
which is the less harmful solution for my eyes.

They're different things. monitor=vesa is "special" in that it tells vga(8) to use the VESA bios calls; xga is just another monitor definition and will try to go through a card-specific driver. All other things being equal, non-vesa stuff will generally yield better performance. Some of the drivers make use of various forms of acceleration, all of which (afaik) are absent from VESA.
