Other Help Topics :: fb0 Device



The How-To is about how to activate a fb0 device on a computer that is having this error:

modprobe: modprobe: Can't locate module fb0
XIO: fatal IO error 104 (Connection reset by peer) on X server ":0.0"
after 0 requests (0 known processed) with 0 events remaining.

Or something to that effect. This might solve other errors too, personally, I'm not sure.

To begin, if you are having the above error, you will boot into a console after it.
Now, type cd etc at this console then type nano lilo.conf. This should have gotten you to a text editor showing the configuration

file of LILO, the linux bootloader. Now, look for a line that looks like this:

vga=791

The number might be diffrent, but I believe that's the default. After you have found this

line, you're going to need to edit the number there. The original number doesn't work so
you need to try others. Here is a list of valid parameters for this.

 Colours                               Resolution
              640x400 640x480 800x600 1024x768 1152x864 1280x1024 1600x1200

Once you have edited lilo.conf, press and hold CTRL and press

X then press Y to save it, and then press ENTER.

Now, you should be back at the console. Type lilo to have LILO, the

Linux Bootloader, re-read the configuration file. If you skip this step, your computer might

not be able to boot-up, resulting in a re-install of linux, or just the loader. You can now

restart the computer, and when you boot up you should see a little penguin in top-left hand

corner. To reset the fb0 device to the way it was, instead of putting a number, put

normal. I have tryed this on a NM2090 (NeoMagic Graph128V). Please

leave your video card's manufacturer and chipset/model number and amount of memory if this

worked for you.
Thanks Crotalus!  Just a quick add, if you are running from the CD on a laptop made in the mid to late 90s try booting with fb800x600.  If the framebuffer is working then you will see the little Tux penguin in the upper left corner.  Then you will be able to run Xfbdev.

By default Knoppix and DSL tries to establish a framebuffer at 1024x768 which is too much for many laptops from this period.
If you get the Undefined Mode Error, this will fix that too.  :;):
this helped me alot :) thanx to dan for showing it me (this post i mean) and Crotalus for the info via this post

all i know is that my graphics card is a neomagic 1mb on a compaq presario 1020

thx Crotalus
Thanks for the hint, but for me it doesn't work:

IBM Thinkpad 560 (2640-10u), Trident Cyber 9385/82 PCI with 1MB videoram

still the same error....

any ideas?
