blank screen at boot when using lilo FB


Slackware 12

When I set up lilo with
vga=773
I get the lilo message and the traveling periods at boot. But, then the screen goes blank.

I have enabed nvidia framebuffer and VESA for vga in the kernel. I had this working on my slackware 9.0. Why is it not working on 12.0? in the /avr/adm/messages there are lines that indicat the frame buffer is running on fb1. I would cut and paste those, but I am installing 12 on a seperate system.

Any help?

I have run into the same problem with a fresh install of Slack 12 on my system (ATI X800XT video). After lilo I see the periods, and then nothing. I can login as root and reboot, but I can't see squat. I've got the latest ATI driver ready to install, if I could only see what prompts would pop up.

UPDATE: I started with vga=ask, selected 80x25 and was able to see my login prompt when it booted. I installed the ATI driver and proceeded to start X. The screen flashes with a bunch of colored squares and then I get a message from my LCD (Samsung 940BW) that the refresh rate is incorrect. I opened up /etc/X11/xorg.conf, but didn't see any refresh rates given. I saw resolutions and color depths, but no refresh. Any clues? I'll keep digging in the meantime.

In your '/etc/X11/xorg.conf' file you should find something like this in the monitor section;

Code:
excerpt from '/etc/X11/xorg.conf';
# **********************************************************************
# Monitor section
# **********************************************************************

# Any number of monitor sections may be present

Section "Monitor"

    Identifier  "My Monitor"

# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    HorizSync   31.5 - 50.0

#    HorizSync  30-64         # multisync
#    HorizSync  31.5, 35.2    # multiple fixed sync frequencies
#    HorizSync  15-25, 30-50  # multiple ranges of sync frequencies

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    VertRefresh 40-90
You should set up for your monitor/LCD specifications.

Excellent! Thanks Onebuck! I forgot that I had to do that a while back when I was trying out a different distro (possibly a previous version of Slack, more than likely). I've been spoiled by Suse setting everything automatically I guess. :P Back to the DIY distro........hehe

One problem solved.............one more to go............in another post........
