Video Resolution, editing xorg.conf not fixing [Solved]

[chasashmore]

I'm new to Sabayon (used Gentoo for a few months a couple of years ago). Coming from KDE Mint.
Can't get proper resolution on my laptop monitor -- I want 1280x800, but can only get 1024x768. Have read numerous posts on resolution problems and the wiki on changing resolution, without luck.

I have a system76 Gazelle Ultra laptop (gazu1) made for ubuntu, with a 13.1 inch screen, onboard intel video chip. Am using Sabayon 7 for AMD64, all works great (everything important, that is) except video resolution. I tried editing xorg.conf, putting 1280x800 first in the list of resolution under each of the different color depths, but when I reboot I still have as options only 1024x768, 800x600, and 640x480 in the system settings program.

In other systems (Mint, Kubuntu, Knoppix), the driver used is i915, and that seems to be what Sabayon is loading, at least it is listed by lsmod. Relevant parts of my xorg.conf file are as follows:

==<begin xorg.conf>========>>

Section "Monitor"
Identifier "Generic Monitor"
VertRefresh 43 - 60
HorizSync 28 - 80
EndSection

EndSubsection

<<==========================<end xorg.conf>===

Again, the 1280x800 was added by me, but does nothing.
Any help gratefully received. Thx.

Hi.

Your monitor may require a different refresh rate at 1280x800 than the ones provided in your current xorg.conf.

Do this:

In xorg.conf you have this line:

VertRefresh 43 - 60

Try to change 43 - 60 to 43 - 76

then reboot.

If that doesn't work, try 43 - 81.

Good luck.
