G550 Dualscreen-DVI setup - framebuffer possible?

Postby AndreasMeier » Wed Jan 03, 2007 3:34 pm

Hi there,

as written here, I have a G550 with a DualScreen Setup which is working over DVI.

Now I'm wondering if it possible to add a framebuffer for alle the messages at system startup and for the console, in order to have a smaller font size etc.

Can you guys give me some hints where to start the search ?


Thanks in advance,
kind regards
Andreas

Should be possible, yes.
The relevant parts for configuring matroxfb are inside the linux kernel.
You will need some kernel modules/functions enabled that provide support
for the matrox framebuffer device on G-series cards.

To configure the features required for matroxfb, you will need the following
kernel modules/functions enabled:

Device Drivers -> Graphics support -> Matrox acceleration and some stuff below
that, depending on what your hardware looks like and if you want I2C or
dualhead support, etc.

After recompiling your kernel (I'd suggest to link this functionality directly
into the kernel, when using kernel modules you will have to update your
initrd to contain these modules if it doesn't already), you will need to
activate this kind of framebuffer mode.

For more information on this task please read the fb-documentation inside
the kernel tree, which is located in "/usr/src/linux/Documentation/fb/matroxfb.txt".

Hi together,

as I told you, I'm running Debian etch on my machines.
Now that my dualscreen config is working smoothly, I wanted to have the bootsplash-things installed in order to get a smaller font size during boot.up from the system.

Packages are in apt-get available, so I installed it.
I made also the update to GRUB (vga=0794 splash=native for 1280x1024 resolution).

Now the system comes up with the font size I wanted.

The only thing I want in addition is the little tux pinguin in the edge of the screen during startup like it is configured in KNOPPIX for example.

Any ideas how to get this done ?

Thanks in advance,
kind regards
Andreas


PS: my dualscreen config is not effected from the configuration right now, all is working well together.

This usually is only a matter of configuring your kernel.

Code: Select all
cd /lib/modules/$(uname -r)/build
make menuconfig


Device Drivers -> Graphics Support -> Support for Framebuffer Devices -> Logo configuration -> Bootup Logo

There you have to check the appropriate image (224 colors is the right one).
Afterwards, save the configuration and recompile and reinstall the kernel
image:

Code: Select all
make
make modules_install
cp arch/i386/boot/bzImage /your/kernel/image/location
cp System.map /your/System.map/location

Do I understand that right?
If I check the box in the kernel config, the pengiun will be displayed during the bootup ?
Nothing more?

Checking the box means altering the kernel configuration and thus
recompiling your kernel as well as installing the newly created kernel
image is necessary.

But, yes, nothing more :)
