This is a near-perfect solution for me to get a better resolution than 640×480, but is still not quite right!
I have a an Acer Aspire 5000 with "SiS M760GX" video card (lspci -v
returns Silicon Integrated Systems [SiS] 661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter (prog-if 00 [VGA controller])
) and using this xorg.conf file shown below I can now get resolutions of 1280×768, 1024×768, 800×600, or 640×480, instead of just 640×480, which was waaaaay too low of a resolution. However, my screen's native resolution is 1280×800, so it still looks a little off. ANY IDEA HOW I CAN GET 1280X800 TO WORK?
Note that I'm running Xubuntu 16.04.3 64-bit. The Acer Aspire 5000 is from approximately 2005.

What' I've already tried:
If I try changing "Virtual 1280 768" to "Virtual 1280 800" all it does is make my screen vertically extend beyond the edges of the monitor, so by moving the mouse to the top or the bottom it will pan the screen up or down to see the extra 32 pixels. This is NOT what I want.
Best Answer
There is no way to get the 1280x800 resolution on modern Ubuntu versions.
It was possible on Ubuntu 12.04. Now the X.org doesn't support the SiS obsolete modesetting method.
You can use only VESA modes.
