1024x768?

You might be on the vesa driver. You can only get 4:3 aspect ratios from that, and 1366x768 is 16:9. Give details of your video card(S) and post the output of
glxinfo |grep render

We can't really suggest much without those, and it's different for each manufacturer.

Sorry it is 1024x768.


$ glxinfo |grep render

direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)
GL_NV_conditional_render, GL_NV_fog_distance, GL_NV_light_max_exponent,

OK. If you have an ATI card, all seems well there.

Have you open or closed source drivers? If you have OSS drivers, /var/log/Xorg.0.log will spout page after page of debug output including a complete card list.

Time to check if what video settings if any are in /etc/X11/xorg.conf.d/*.conf. It's getting 1024x768 from somewhere, and we just have to find where. There could also be something in
/etc/X11/(xinit/)xorg.conf.d
/usr/(X11R6/)lib(64)/X11/xinit

with the bits (in brackets) as extra possibilities.
also post the output of lspci

If the OS has a way to set video, set it.

I had a quick scan of the Xorg.0.log

You have the VESA driver. Vesa is a very old standard (there used to be a vesa bus before we had pci busses) and it only knows about 4:3 monitors, whereas you have 16:9 (aspect ratio). That's where the 1-024x768 is coming from.

You need to load the correct video driver for your card, and can uninstall framebuffer and vesa once you get that up and running.

Run lspci to find out what card you have (if you don't know).

That's it. The P4M800 appears to be your Northbridge and the 82C686 appears to be the Southbridge. The vides seems to be in the Northbridge.

If you can't find a via video driver, bleat on the forum for your distro. If that fails, try the Via site - viahw.co.tw? via.com? It's been a long time.

I am no mint expert - running slackware here, and kinda busy too.

Try Via's site, or google for a linux driver.

This may help ???

I'm a newbie so you take this for what it's worth. I just installed mint 16 petra and had a screen res issue also. I only had the default res with no options under system > display. Found the package KrandRtray (screen resize and rotate) and installed it. Went back to system > display and now I have the size and orientation option. It worked fine so maybe it will work for you.

Probably should be using the 'openchrome' driver-

https://wiki.archlinux.org/index.php/Via

Yes, thats the arch wiki, not mint, but the information there is good
