 Posted: Mon Oct 03, 2005 8:16 pm Post subject: Grub error...please help! |
 |
|
I am able to run the kernel but after the first page of text the screen freezes and I get fuzzy blocks everywhere. Nothing further happens after this.
I've tried looking at my grub.conf file using the cat command but all I'm getting this time is question marks with fragmented text. I think my grub.conf file looks something like this but I can't be sure, there may be typos.
| Code: | default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.12-r6
root (hd0,0)
kernel /boot/kernel-2.6.12-gentoo-r6 root=/dev/hda3 video=vesafb:mtrr,ywrap,1024x768-32@85 |
Can anyone help?

| Try removing the "splashimage" line, and the "video=blah..." stuff. |

Mhh this is no error in grub.conf, at least not really.
You are saying that the screen gets fuzzy and blocks and stuff, and freezes?
This would suggest a video problem 
Try vga=ask and it will ask what vga video mode you want, try 0 or something and then see what it does.

i've tried with various framebuffer options but i've had no luck. exactly the same error everytime. if i remove the framebuffer option i get
| Code: | | Error 27: Unrecognised command |
and i can't get at the grub.conf file (afaik) i can only edit the kernel line
actually i'm getting the above error only now
okay tried it again, and without the framebuffer options the system still hangs
putting in vga=ask has no effect the system hangs after the first few lines after "uncompressing...blah blah" |

| Boot using a CD, mount your hard drive partition, and edit grub's menu.lst as I mentioned. That should stop the attempt at eye-candy which is just achieving the dubious result of driving your video card nuts. |

Hmm, does your grub config look exactly like this:
| Code: | default 0
timeout 30
#splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.12-r6
root (hd0,0)
kernel /boot/kernel-2.6.12-gentoo-r6 root=/dev/hda3
#video=vesafb:mtrr,ywrap,1024x768-32@85 |
You will notice that I have commented out (with hashes) the lines which are likely to turn your PC into an episode of The Matrix.
You need to get your PC booting successfully, before messing around with the eye-candy stuff. |

Something's not right. How would grub show a splashimage, if you've commented out the "splashimage" line? It shows the kernel list in text mode by default.
I can only suggest that you boot from the CD again, and double-check the contents of your grub config.
It sounds like the real problem is the "video=blah..." stuff in the kernel line, which I assume must still be present.
Does your video card go nuts as it's booting into xorg, or doesn't the bootup process get that far? It sounds like it doesn't get that far. |

| OK. When you reinstall, do not select the bootup eye-candy. That can be set up later (if you really, really can't live without it...), but it's far more important that you have a system that works. The "video=" gubbins might be a red herring, hiding an ACPI kernel panic, for instance. |
