I have recently purchaced your book, Moving to Linux: Kiss the Blue Screen of Death Goodbye, and am having trouble changing the screen resolution. I followed the instructions provided at http://www.marcelgagne.com/KBSODG/knoppixhelp.html#screenres and typed in "knoppix screen=1024x768" at the "boot:" prompt (without quotations). I also tried "knoppix screen=800x600", but all three (leaving the "boot:" prompt blank, typing "knoppix screen=1024x768", and typing "knoppix screen=800x600") had the exact same results of a 640x480 screen resolution. Windows (the OS) is able to run any of those resolutions on my computer. Note: I am using the Knoppix Live CD provided with the book. |

Re: Trouble changing screen resolution
Hello neko18,
You didn't mention what kind of computer or video card you have so I'm going to hazard a guess that the video card itself is improperly recognized. That may be due to you having a more recent video card in your computer than what the Knoppix disk is familiar with (remember, there is only so much room on the disk). Anyhow, try this at the boot prompt.
Pretty much every video card made in the last five years supports VESA (Video Electronics Standards Association) emulation. Try telling Knoppix to ignore whatever your card is telling it and use this module instead. You may find that you automatically wind up with a decent screen resolution. You can also specify the resolution along with the vesa card type selection.
