 Posted: Sat Nov 29, 2003 5:43 am Post subject: Framebuffer - How do I get rid of them? |
 |
|
Hi,
I configured my kernel for framebuffers, and decided I didn't like them.
I'd like two entries in my Lilo - one for pure plain text (80x25), and the other using framebuffers.
How do I set it so that I can get back to text only?
Thanks.

| Code: | title=Gentoo Linux (2.6.0-test10-mm1)
root=(hd0,6)
kernel (hd0,6)/boot/2.6.0-test10-mm1 root=/dev/hda8 vga=0x317 video=ywrap,mtrr,vesa:1024x768@72 |
If I wanted to stop using a framebuffer, I'd just remove everything after 'root=/dev/hda8' and reboot. That's with Grub, not sure how it works with Lilo, but I'm guessing it's pretty much the same. |

Well, I'm using LILO.
I tried vga=normal. That gives me 80x25, but it does not look "normal" (i.e. before I had framebuffers). In addition, if I do that, the screen is shifted to the left.
Surely, there's a quick way to disable framebuffers?
Thanks,

| I think you disable the framebuffer by not just adding the vga=blah line to the kernel parametres |

Kernel Parameters, or Lilo?
I disabled all vga=... statements in lilo.conf, but I get the same result if I use vga=normal. It still uses some sort of framebuffer, and the text is off center (into the left of the monitor).
Just a reminder to everyone: I want to be able to easily disable the framebuffer without having to recompile the kernel. How?! I liked my good old plain text consoles.
Thanks,

simply removing the vga= and video= lines should disable it, it does on mine...

Maybe you have compiled "VGA16-Framebuffer" into your kernel. Disabling that will give you your plain text mode console.

Sorry, I already tried vga=normal - it's the same as having no vga line at all.
Removing vga= and video= lines don't work.
Just if needed, my kernel framebuffer parameters:
| Code: | #

CONFIG_FB=y

| Code: | title=Gentoo Linux nocandy
root (hd1,0) # Partition where the kernel image (or operating system) is located
kernel (hd1,0)/bzImage root=/dev/hdb3
title=Gentoo Linux +fb +bs
root (hd1,0) # Partition where the kernel image (or operating system) is located
kernel (hd1,0)/bzImage root=/dev/hdb3 splash=verbose video=vesa:ywrap,mttr vga=791
initrd=(hd1,0)/initrd |
works like a charm for me
i've not only removed the kernel parameters, but also the initrd line

Yes, but that's not Lilo...
I think I'll just recompile the kernel without framebuffers, and I'll keep the old one also in the boot partition, so I can still switch between the two.
Just a pain, that's all.

it's the same with lilo
remove the kernel parameters and remove the initrd line, and it'll boot without framebuffer (the kernel), you should also remove the initscript for framebuffers if you don't want it kicking in later
