HOWTO: Change bootup resolution

[sg.forums]

If only 1280x800 was supported...

Does this mean that I would never be able to install ubuntu on my 1280x800 screen laptop ?
Which part of the software don't support this resolution the xorg server ?
Where can we get more info about 1280x800 support ?

Whats the vga setting for a laptop screen resolution 1400x1050
with a dual screen of running 1280x1024 of a docking station.

No, of course not. This thread is a howto for a mod to change the "Bootup resolution". ie. the splash screen with the progress bar you see before x starts. 1280 x 800 is not supported *for this mod*, but of course is supported for xorg or whatever.

To change your framebuffer to something like 1280x800 append "vga=0x368" to your kerneloptions. This looks better then "791" or similar but breaks the centered position of usplash!

hi this was a great and very very informative and well-written post. Thank you very much.
Now I just want to find out how to get coloured fonts in the console, so that files/folders appear differently. Like on the gentoo/knoppix live cds.

About this subject i would like to ask,
Is it possible to set up a background image for the virtual consoles like SUSE does?

I mean, when i hit CTRL-ALT-F1 in suse, i get the console with a background image wich has the suse logo on top, and a sort of shading in it.
In ubuntu it's just black. Can it be changed?

I get:
"You passed an undefined mode", and it tells me that I have just a VESA VGA, and lists all the modes when requested, but then does not go "graphical" until the booting is finished.

The modes it lists are all DOS modes - 80X25, 132x60, 80x43, etc...

BTW have an Intel 82810E DC-133 on board graphics controller.

(Having other probs with it - posts elsewhere- , but I want to see if I can get this one solved here...)

Thanks

I am rather certain that doing so doesn't work at all in Ubuntu. I also know that there are modelines that work for 1400x1050, but I don't remember them right now.

I have found a very interesting tool in this forum, Startup-manager. You can set all the options in the grub and usplash image.

Works great ! Installs into the Administration menu.

Hi,

Was searching for the 1400x1050 settings also, because setting grub to 1280x1024 (image size) didn't display correctly, and came across this post on the gentoo forum: http://forums.gentoo.org/viewtopic-t-333300.html

Where it lists the respective codes for 1400x1050 vga are 834 (16 bit), 835 (24 bit) and 836 (32 bit). I'm using 835 and it's working great (IBM t43 and grub).
