 Posted: Thu Feb 17, 2005 8:58 pm Post subject: grub doesn't display properly |
 |
|
Hello everyone,
On both versions of gentoo I have installed, grub doesn't display properly. The splash image nor the text to choose what kernel you want to boot up into have worked. I have tried playign witht he video modes, but those are the kernel video modes so they don't affect grub (as far as I know). I have tried looking over many manuals with no success. Both machines have built/powered by ATI cards and I was wondering if there is anything specific I need to do to get grub to display properly. So far the only way I know which kernel to boot into is by memory of the grub config.
Thanks! |

Can you post your grub.conf and hardware specific ? APG, PCIe video card ? what kind of display do you have ? DVI or VGA connection ?
And can you describe, is it black screen, text or garbled screen ?

Here is my grub.conf file
| Code: | # The Default to load into
default 0
# Timeout to load into default
timeout 15
# This is a cool looking splash image ^_^
splashimage=(sd0,0)/grub/splash.xpm.gz
# Bootup for gentoo-dev-sources 2.6.10
title=Gentoo Linux 2.6.10-r7
root(sd0,0)
kernel /kernel-2.6.10-gentoo-r7 root=/dev/sda3
# Bootup option for gentoo-dev-sources 2.6.9
title=Gentoo Linux 2.6.9-r1
root(sd0,0)
kernel /kernel-2.6.9-gentoo-r1 root=/dev/sda3
|
The card I have is a PCI Express video card on a Flat Panel monitor with a VGA output.
The other machine is an AGP Radeon 9600XT on a CRT monitor with VGA output.
At first, the screen is blank witht he flashing cursor, then you select a kernel and then it is all garbled until the kernel does its own terminal font setup to ASCII then it goes clear from there. However, if I select a kernel and some error occurs (such as undefined video mode) then it shows text with a little bit of garble, then when I go back into the menu, it shows text although garbled.
Thanks for your help! |

Stupid question, your boot partition is ext2, yes ?
Does the splash image in /boot/grub ? did you try without one ?

My guess is that the splash image is not in | Code: | | (sd0,0)/grub/splash.xpm.gz |
I had the same problem because I was following the installation handbook without paying much attention and it assumes a separate partition for /boot which in my case wasn't.
Thus my splashimage was in | Code: | | (hd0,3)/boot/grub/splash.xpm.gz |
not in | Code: | | (hd0,3)/grub/splash.xpm.gz |

Ok, well the boot partition is ext3 not ext2,
and it should be (sd0,0)/grub/... because sd0,0 is sda1 where the boot partition is. If it was sd0,2 (where my main partition is) then yes I would have to add the /boot/grub/... Unless there is something i am totally missing. As well, would that address the odd text issue as well?
Edit: adding the /boot/ at the front didn't change a thing, as I expected. However removing the splashimage line did show the screen properly. |

Good news...somehow 
To go further on splash image, look here :
http://ruslug.rutgers.edu/~mcgrof/grub-images/
I don't know if you used standard image or tried to make your own.... In Chapter 1, there is details about requirements for image and how to test it from command line inside grub. In case you want to play around with it.

| Ok I will have to take a look at that. The image I had set was the default one that came with the grub ebuild so it seems odd why it wouldn't work =/ |

Check also the script he gave to test if your grub support splash image or not ?? by default it should but just in case...

Yep, splashimage support was found so that isn't the problem.
I also tried downloading on the publicly available ones that apparently work and the result was it didn't work =/
the line was
| Code: | | splashimage=(sd0,0)/grub/gentleblue.xpm.gz |
and that didn't work =/ |

well I fiddled around with it and eventually got this to work
| Code: | root(sd0,0)
splashimage /grub/splas.xpm.gz |
It's probably not the best way to do it, but it works ^_^ |
