(I didn't say the _resolution_ isn't real - I know it is real and I know
it is in use.  I was questioning the reality of the popularity part).

But note again: despite its popularity, it isn't sufficient to add it
to seabios, other parts of the picture should support it too, and we
have a widely used piece of software (qemu) which does not support it
currently and is known to crash if someone tries to use this resolution.
_That_ should be fixed first, and it is not a task of adding 3 simple
lines to resolutions table, it is a bit more than that.

Thanks,

According to Google 

https://www.google.bg/?#q=most+popular+screen+resolution

most popular screen resolution since 2010 is 1366x786
despite 1366 is not dividable to 8.
And my laptop has it

Many laptops have it as their native display resolution, for example the
Lenovo IdeaPad B590:

http://shop.lenovo.com/gb/en/laptops/lenovo/b-series/b590/

(It's an exceedingly annoying resolution, granted; but it *is* real.)

That was a security bug then. Let's hope that the fix for CVE-2014-3615
covered that case too.

It is not sufficient to just add that resolution to seabios list.
I mean, it is not only bios which should have support for it.

For example, qemu/kvm will not work with it.

The problem here is that 1366 is not dividable by 8.  In other words,
each line on the screen does not end at a byte boundary in memory.
This is a very weird resolution.  Most devices which actually implement
it use 1368x768 and just crop two vertical one-pixe-wide lines on both
sides.

This does not look real.  Being a very weird resolution, with very
few devices available in stores all around, it can't be real.

But even if it _is_ real, it does not make this resolution any
less weird.

[SeaBIOS] resolution 1366x768

2014-11-14 Thread Bozhan Boiadzhiev
Hi, 
i have a laptop with resolution 1366x768 and SeaBIOS doesn't have such.
Please, if it is possible, someone who can, to add this resolution to 
vgasrc/bochsvga.c.
According to this page https://en.wikipedia.org/wiki/Display_resolution,
resolution 1366x768 is used by 26% from Web users,
based on stats from 
http://gs.statcounter.com/#resolution-ww-monthly-201401-201404-bar

Thanks
