Can anyone help me with the following?
Do any of you know how to make uvesafb (that replaces the old vesafb-tng)
set to a pre-defined resolution?
What I mean is that with vesafb-tng I used to set like: "1440x900@60" as fb
settings and then, during boot, while kernel was loading, when it passed
through that "instruction", it would start using the console with those fb
settings and the penguins on the top. Then the penguins disappear and I had
a great text console @ 1440x900.
I remeber putting the exact string 1440x900@60 when building my kernel on
the vesafb page. Now with uvesafb I don't get that option and my text
console has a horrible resolution. A simple "lspci" will generate text long
enough for a line to break.
Anyone?

Regards,

Saffi

Hi.

Try to determine possible resolutions by typing "hwinfo --framebuffer". Use the 
hex code 0x... and put it as kernel parameter in your grub.conf.

For 1400x1050 with kernel 2.6.24-r3 I am using the following lines:

title Gentoo GNU/Linux (gentoo-sources-2.6.24-r3)
root (hd0,1)
kernel /gentoo-sources-2.6.24-r3 root=/dev/sda5 vga=0x344


Regards,

acm.

Yes I am using gentoo-sources. I think since kernel 2.6.23 (or maybe 2.6.24) 
there is only uvesafb - nothing else to choose. uvesafb replaced vesafb-tng.


Greets,

Okay, *that* I didn't know. :-)
I do know 1440x900 is a supported resolution on my machines since it's the
native resolution of their screen's.

So after the change from the vesafb-tng to the actual uvesafb on the kernel,
it actually IS necessary to use the "vga=something" trick on the boot line,
then?
I'll do it and tell the results.

Thanks a lot, Alexander!

Best regards,

Saffi

i always thought vga= was only used by the old vesafb driver
i use video=uvesafb:1024x768-32
i cant get any wide screen modes to work at all, anybody else know how??

Nice, new thoughts being added to the discussion. That's good!! Let's keep
the brainstorm. :-)
Any ideas?

Did you tried to find out what resolutions are supported by your graphic card 
(e.g. hwinfo --framebuffer)? I only know this tool to get the necessary hex code.
So I don't really know if the vga= option works with uvesafb too.
I have to correct my statement that I am using uvesafb. It seems that I am using 
vesafb. This is because I don't want either any additional userspace application 
(v86d) nor bootsplash etc.


acm.

You have to select Connector - unified userspace <-> kernelspace linker in 
the Device Drivers page. Then you will have uvesafb available for 
selection.

It seems that you also need v86d installed, and start with an initramfs with 
that in it, though I haven't yet finished working this out for myself.

tutorial, but this part is not there, yesterday i check the official web and
i see this part, now is working great! Many thanks!.
I have a n old notebook with a intel video chipset (810) should i use the *
intelfb* instead of *uvesafb*?

BTW: Is there any chance to avoid to see my background images when the
kernel end load and just before kdm start? I get the image i choose two
times...and it would be great if i just keep a dark screen or somethinf
similar.


Many thanks,
Cheers!

I did try that. But it suggests many different things. None of them works as
I want it to  (or as vesafb-tng would when I set up the resolution by myself
on the kernel config). And worse: for me to try every option vga=ask provide
me, there are several reboots. So...
