wrong boot screen resolution!

[BlSabbatH]

i've installed kubuntu 5.10 on my laptop, and i've an estetic problem when i boot up..
the screen resolution is wrong: words appears ok on left and right side, but seems to be squeezed in upper and down side of the screen!! usplash theme is not centered...a very sad beginning!!
after, when x session starts, all is ok, in 1024x768 resolution
any idea??

I noticed after recompiling the kernel that Kubuntu by default boots up with generic VGA 16 linux driver instead of your specific videochipset driver.(probably because this gaurantees support for you videocard at boot.)

As soon as I compiled "radeon" support into the kernel suddenly my console bootup was the correct resolution.

This worked for me:

sudo dpkg-reconfigure xserver-xorg

On the page where it shows available resolutions, make sure that the highest res selected matches your desktop res. Then on next boot the splash screen should be the same as your normal desktop res.

Add
vga=791 to the /boot/grub/menu.lst.
For example, if your Grub entry looks like this:
title Kubuntu Linux
root (hd0,0)
kernel /boot/vmlinuz-2.6.12-9-386 root=/dev/hda1 ro quiet
initrd /boot/initrd.img-2.6.12-9-386
savedefault
boot then change it to this instead
title Kubuntu Linux
root (hd0,0)
kernel /boot/vmlinuz-2.6.12-9-386 root=/dev/hda1 ro quiet vga=791
initrd /boot/initrd.img-2.6.12-9-386
savedefault
boot

I tried adding vga=791 to menu.lst and when restarted my computer, I got no graphical boot screen. Instead it gave me an error that kernel module vesafb.ko is not found. Why does it need this module? It's a generic display driver if I'm not mistaken.

I have nVidia card with drivers properly installed.

Got this in my menu.lst



kernel /vmlinuz-2.6.12-9-686-smp root=/dev/hda2 ro quiet splash video=vesa vga=0x317


for 1024x768x256 colors.
Works perfectly.
