Is it possible to change the resolution of the GRUB bootloader itself. I have a Viewsonic 1912w LCD which wont display the bootloader as the resolution is too low. It also won't display my Bios screen but that's a seperate issue.
I have to guess when GRUB has loaded and 'fly blind' with the keyboard to boot into Linux. I have looked at the menu.lst file and can't see any option to change the resolution of GRUB itself, only options to change the res at which Kanotix boots.
Please help!!!!  |

Sorry, OSD on the monitor itself? It just doesn't support the default GRUB resolution. I need to make GRUB display in 1024x768 or higher. Native resolution of the monitor is 1400x900.
I have sent Viewsonic a tech support query asking why their monitor wont scale to a standard boot screen resolution but as yet no reply!!!
If I can alter the resolution that GRUB displays I can at least choose Linux or XP without guessing. |

Sorry you are having a problem but glad you reported it. This is similar to the problem that caused me to quit using Kanotix. I have a 17" Plannar LCD Monitor. There is an error message with each bootup, however I am able to read the text after I click out of the message. It does continue to boot but adds a bunch of extra steps and it is ugly, too.
If you find a resolution to your problem I hope you post it on the forum, or at least send me a copy.
regards,

P.S. Let me ask, outside of this are you satisfied with the distro? j |

nope. GRUB, as for now, only allows 640x480 resolution in the bootmenu.
Cheers

Thanks for that info.
You know, my husband ran the live-CD on his computer and the bootup menu was beautiful and in a high resolution. On my monitor it is 640x480 and has a big ugly black error message on a bright green screen.
Hope we can get it straightened out,
Cheers,

My monitor manual says it supports the following resolutions...
1440 x 900 @ 60 Hz
1280 x 1024 @ 60, 70, 72 Hz
1024 x 768 @ 60, 70, 72, 75, 85 Hz
800 x 600 @ 56, 60, 72, 75, 85 Hz
640 x 480 @ 60, 75, 85 Hz
720 x 400 @ 70 Hz
...so I'm not sure why I cant see my bios screen or GRUB. Their tech support won't respond. Guess its a hardware problem. Thanks to all who replied |

Someone suggested that my problem may be video driver during boot and not the monitor. I have not delved into that yet. I will try to get a screenshot of my booting view and post it.

janice
This is what I see when I am booting.

| comment "gfxmenu ..." (put a # in front of the line) in /boot/grub/menu.lst, strangely gfxboot is crashing on your h/w, since we're in the process of reworking the gfxboot menus right now, it might be interesting to test again with the next release. |

Thanks slh,
Later today I will do that. Right now, my husband and I are going to go cut down some trees on our property. Ugh! Hot work but it has to be done.
