The three numbers in the list represent, in order: - the horizontal resolution - the vertical resolution - the colour depth, i.e. the number of different colours that can be displayed at each pixel. You can also see colour depth expressed in terms of bits-per-pixel or bytes-per-pixel, e.g. 256 is 8 bits-per-pixel since 2^8 (2 raised to the eighth power) = 256. > > vga=791 - VESA framebuffer console @ 1024x768x64k > vga=normal DON'T USE FRAMEBUFFER | Standard console > vga=790 - VESA framebuffer console @ 1024x768x32k > vga=773 - VESA framebuffer console @ 1024x768x256 > vga=788 - VESA framebuffer console @ 800x600x64k > vga=787 - VESA framebuffer console @ 800x600x32k > vga=771 - VESA framebuffer console @ 800x600x256 > vga=785 - VESA framebuffer console @ 640x480x64k > vga=784 - VESA framebuffer console @ 640x480x32k > vga=769 - VESA framebuffer console @ 640x480x256 > > I experimented long with these, and saw that the x256 choices, (773, > 771, 769) > all gave visible boot up image and progress bar - the 773 gave a nice > central display. > Unfortunately these all also led to very poor text/font display (in > kde, kubuntu). > > The poor text display became apparently good and normal again if I > restarted the xserver (ctrl alt backspace) Unfortunately, I can't solve this problem. I do have one suggestion - maybe you can tell X not to use the framebuffer, since the console is now set to use the framebuffer. > All of the other vga numbers did not give any boot up image etc, > although subsequently the session showed normal text quality. > > Is there an elegant way of restarting the xserver at the start of a > session?

I think someone else mentioned removing the "splash" option from Grub, so try that. I think your problems stem from the non-standard hardware that is used in most laptops, which is not fully supported in Ubuntu (and probably not in most Linux distros).
