Change Screen Resolution During Boot-up?

Javelin Dan · 12-12-2011, 11:01 AM

I would like to install Zenwalk on my ancient Dell Inspiron 8000 laptop. I have successfully made a bootable flashdrive of Zenwalk and intend to boot with the aid of “Plop” as my CD drive is toast on this machine (I have done this many times with Puppy). I have actually successfully booted this once except that the default screen resolution is unusable. If I remember correctly (not sure I do), I believe the optimal resolution with Puppy Linux is 740/1280 or there abouts. Can someone give me step by step directions to either adjust the resolution in Xorg or switch to Xvesa during boot-up? Please note that I am a newbie with no expertise using the command line. All help is appreciated – thanks!

FRAMEBUFFER RESOLUTION SETTINGS
# +-------------------------------------------------+
# | 640x480 800x600 1024x768 1280x1024
# ----+--------------------------------------------
# 256 | 0x301=769 0x303=771 0x305=773 0x307=775
# 32K | 0x310=784 0x313=787 0x316=790 0x319=793
# 64K | 0x311=785 0x314=788 0x317=791 0x31A=794
# 16M | 0x312=786 0x315=789 0x318=792 0x31B=795
# +-------------------------------------------------+

# TIP: If you want a 1024x768 framebuffer, add "vga=773" to your kernel line.
