Question How to change / set screen resolution during boot


I have recently started using Linux. I am currently configuring a copy of Damn Small Linux on my old, old laptop to give it a new life as a MP3 player for the car.

There seems to be a troublesome quirk during startup where LILO (or Linux) thinks the screen is 1024x768 instead of the physical 800x600 of the LCD screen. Once in X, the Window Manager handles the screen resolution correctly.

Is there a way to correct the screen resolution during boot / startup? This helps with the occasional error messages that appear on the "invisible" part of my screen awaiting response.

I've read that DSL is a stripped down version of Debian. Oh, my old, old laptop is a Toshiba Satellite Pro 420CDT (100 Mhz! w /48 Mb!! / 2G HD)

Thanks in advance!

Oooh, I think I've found the place! But it's not working!


There seems to be a value called vga=791 at the top of this file.

I changed it to 788 (from this table)

Resolution in Pixels

color depth | 640x480 800x600 1024x768 1280x1024
256 (8bit)| 769 771 773 775
32000 (15bit)| 784 787 790 793
65000 (16bit)| 785 788 791 794
16.7 Mil. (24bit)| 786 789 792 795

But it's still trying to write off of the screen! Arggh!

I'll try the X11 thing mentioned about, but my X-Windows is just fine. It the single-user boot up screen sequence that's giving me problems... :-(

After a few tries, I see that setting vga=769 works properly....

Sorry for the confusion I've generated--it wasn't about X Windows at all!
