I can't set right bootsplash resolution for a 1440*900 widescreen

[Caste]

Hi everybody!

First of all, excuse me for my worst English (I'm Italian).
It's a few that I try to change my splashscreen resolution on my Kubuntu 7.04...I have a 1440*900 widescreen monitor and a GeForce Go 7600, but when I've tried to modify /boot/grub/menu.lst and write the vga code (vga=867), it seems not working.
Instead, until I've modified menu.lst and also /etc/usplash.conf, when I shut down PC the usplash seems to work, but only for a few seconds...after a while, monitor turns black and when reappear the usplash it's as ever (with 1024*768 resolution, I say).

At the boot, instead (ever when I've modified menu.lst and usplash.conf), usplash don't start and give me this error:

'You passed an undefined mode number. Press <RETURN> to see video modes available, <SPACE> to continue or wait 30 secs'

When I try to press R (for <RETURN>), PC gives a 'bip' and don't do nothing, so I have to press spacebar or wait to start the session.
Someone says that probably it happens because this mode isn't supported by my graphic card BIOS (it's 05.73.22.50.16), but I don't know it.

Is there a definitely way to change my resolution?
Thank you for the answer, and excuse me again for my English.

Caste.

I always disable the boot splash screen. This avoids some problems with the nvidia driver as well (or at least did so in the past) because the screen can remain in VGA textmode until X is started.

what the hell made you think it was 'R' ? 'return' is the 'enter' key.

boot splash screens use framebuffer, usually via vesafb(-tng), and vesa modes don't include modes outside the ultra-standard ones (like 640x480, 800x600, 1024x768). some vesa vbe tools I can't recall will give you the vesa mode list your card can support.
