Hi Kelly, If you can see the boot up screen there is probably a different 
problem then what you think it is. The default boot resolutions in Frame Buffer 
mode are 1024 X 768, which grub utilizes. If you can see the cliffs and the 
progress bar, then your monitor would appear to support 1024 X 768, if it did 
not, you would not have even gotten as far as seeing the boot splash. If that 
is the case this indicates a configuration problem with the Xserver. However, 
if you can hear sounds but have no picture, this would also be odd, as the 
default desktop resolution is 1024 X 768, which indicates that there is no 
problem with the screen resolution if you can see the boot splash.

However if you would like to try to change the Frame Buffer resolution, which 
is the only one that will be effected by a commandline kernel argument, then 
you would use vga=xxxx, xxxx Equaling the correct number. There are some grids 
of the resolutions. However Ill post this one,vga=788 , which is 800 X 600 in 
16 bit mode.

This is a list of frame buffer modes:

      640x480 800x600 1024x768 1280x1024 
8 bpp  769       771     773     775 
16 bpp 785       788     791     794 
32 bpp 786       789     792     795
