GMA3600 max resolution on asus eeepc X101CH

[acypkob]

max resolution on asus eeepc X101CH is 800x600, which is not native but 1024x600 is native it it Atom N2600 with intel GMA3600 built in Haiku boot menu gives no more than 800x600 either

[07:25] <@PulkoMandy> cypa: with the vesa driver we should already pick the best resolution and there is no easy way to force a specific resolution (otherwise we would have done it already)

[07:25] <@PulkoMandy> so if the non-vesa driver doesn't work, that should be fixed

[07:26] <@PulkoMandy> or maybe you can try with UEFI but there's no official support yet

[acypkob]

so how to set resoution manually? just like X.org modeset

[diver]

Haiku vesa driver doesn't support it.

[pulkomandy]

X.org with VESA likely does not support it either (or if they do, I'm curious to hear hwo they achieve it).

Your only ways out are:

• Get the intel_extreme driver to work on that machine, or
• Use UEFI, which does not use the VESA driver so it can set video modes in a different way

[pulkomandy]

Can you give us the output of "listdev", to see which video hardware is used on this machine?

[diver]

On linux this device is handled by cedarview_gfx kernel driver.

[bipolar]

Those PowerVR based Intel GMA (500, 600, 3600, 3650) were always a pain to work with due to poor (or lack of) drivers everywhere.

Just for reference: Linux 3.1x used to have one DRM driver called gma500_gfx (AFAIK, continuation of cedarview_gfx). It seems it got dropped on 4.15, and now uvesafb is the only option for those cards (according to ​ArchWiki).

VESA driver, with BIOS patching enabled perhaps, might be the only viable/reasonable choice on Haiku.
