If you use vga=791, that mean you will use vesa driver to set mode. 1366x768 is not a standard mode and normally will not be pre-set in the video bios. So you can not find it and use VBE standard call to set/get this mode.
Maybe you can try `modprobe intelfb mode=1366x768...@50`.

I am using Intel 945GSE / ICH7M chipset Panel PC with integrated Intel 945GSE display chipset. Different size and resolution LCD screens are interfaced to the hardware (it supports Dual Channel 24-bit LVDS). I am using Linux VESA frame buffer for various graphic object implementation.I am able to get 1024x768 screen resolution using VESA frame buffer, but I am not able to get the full screen resolution of 1366x768 pixels supported my LCD screen. Currenlty for various resolution I am changing boot configuration file as below e.g. vga=791 for 1024x768. My existing BIOS does not list the 1366x768 resolution. So I would like to know how I could get the full resolution using the exsiting hardware. Please help me. Thanks & Best Regards, Sanjay
