Re: FC3 Graphical Boot and Install Problems - SOLVED!

So this may sound odd, but my graphics are now working:

After trying the vesa, radeon, fglrx, and vga drivers, and recompiling a custom 2.6.9 and 2.6.8 kernel as well as updating FC3 via yum, I could only get a non-scrambled screen when using the vga driver in 8 bit color. Even then, though the system thought (in "Display" under System Settings) it was in 1280x1024, all I saw was a "zoomed in" picture of the upper right hand corner. I kept trying to think what had changed since I had last booted FC2 (been a while, unfortunately, as school gets in the way of my linux messings), and only could think of two things: I bought an ATi HDTV Wonder, which made no sense if it screwed things up; and when Doom 3 came out, I played with my AGP Aperture settings. As little as I thought that would make a difference, after hunting through my Xorg.0.log file and paying better attention on boot (those messages flying by are hard to follow), I finally noticed that there were some random memory allocation errors and PCI probe warnings regarding PCI:01:00:0 (my AGP graphics card). It said it "fixed" them, or they were only warnings, but when I switched the AGP Aperture back down to 64MB from 128MB, sure enough, all is now well...

Tried changing driver to "vesa", same result.  I get a very scrambled
screen (I can barely make out the "Fedora Core" logo a couple times
across the middle of the screen) at all color modes and resolutions.
I also tried getting the proprietary ATI drivers on a flash drive and
rpm'ing them in, just to see if even in 2-D the fglrx driver would
work, but same result once again.  Would changing the VendorName and
BoardName have an effect, or are those just to make the configuration
keep track of what kind of board you're using so you can access that
info later?

I had trouble back in RH9 getting the DVI output on my old nVidia card
working right, but haven't had any trouble since until I tried
upgrading to FC3. Could it be the new xorg not liking my setup? The
Xorg setup that went in FC2 didn't give me any trouble though.

Well finally after getting it to boot in runlevel 3 I was able to
modify inittab to always do that. I've narrowed the problem down to
the radeon kernel driver. If I go into xorg.conf and change the driver
to vga, I can get X to start properly and display things mostly right,
but with oddity: it only works in 8-bit color mode (since that's
apparently all vga supports), and no matter resolution I set it to, I
get this 640x480 screen "zoomed" in on the upper left hand corner of
the screen (i.e., only showing the upper left quarter of the desktop).
Its odd that the kernel radeon driver won't work, since it did for me
in FC2.

New problem. Any new ideas anyone?

Try the VESA driver? I had to change mine also.


Section "Device"

Section "Screen"
#       Driver      "via"
#       BoardName   "S3 UniChrome"
         Identifier  "Videocard0"
         Driver      "vesa"
         VendorName  "Videocard vendor"
         BoardName   "VESA driver (generic)"

I had similar problems trying the vesa driver on an 815 video card. (scrambled screen). Could the falure be similar to the i810 causing the scrambling? (needed to add option noaccel to xorg.conf.)

Since your card states that it is an s3 Unichrome, have you tried using the s3 or s3virge drivers?

Rough ideas is all I can think of. Have you read man via for different
options using the via driver?


When speculation has done its worst, two plus two still equals four.
