howto disable/correct frame buffer? Distorts boot screen...

Hey all,

Weehooo! Windows free at last! After dual booting Slack and XP I decided to get rid of XP and, hell why not. give Debian a try on the fresh and shiny partition.

All went well, surprisingly because half of the time I couldn't read the config questions because the screen was (how to explain this....) not focussed... as in shifted to below and the left of the LCD screen. Thought it would be cleared up after proper installation and configuration.

But now when Debian boots, it's still like that as soon as (I think) the frame buffer starts. For example, I only see half a penguin at the top! :-(

Anyone know how to correct this, for example with some boot parameter? (don't really want to start to recompile the kernel yet)

Cheers, Leon.

[EDIT] BTW, after the boot messages have flashed by, and gdm starts, everything is ok with the screen.

here is an example grub entry that shows you how to change the framebuffer settings using the "vga=xxx" option passed to the kernel. there is a comment which explains what you want to replace "xxx" with.

In the /etc/lilo.conf, edit the vga line to read:


In the /boot/grub/menu,lst, in the kopt line, do the same as above, or add it to the kernel line at the end after 'ro', in the menu.lst.

vga=xxx does not help.
By the way, I chainload the Debian boot(if that's the right expression). Debian entry is now under 'Other' in Slack's /etc/lilo.conf I tried changing the vga=xxx in Deb's lilo.conf, and it does have an effect until the framebuffer starts. Then the vga= gets back to default letter size and the above described problem.
I think I have to disable any other frambuffer than my card-specific one (SiS630) in the kernel. Tried to get a kernel source from one of the install cd's but couldn't find any. Now i'm online, makes life easier.

How does one read the different packages on the install cd's? (I mean, I couldn't find any listing on the cd's, like packages.txt or something like that)
