I have an IBM 701c 'Butterfly' laptop. I have Slackware 10 running on it.
It uses the Chips And Tech CT65545 chipset, and it is capable of doing 640x480@256 colors on the screen. And 1024x768 if i hook up an external monitor.
Now, my trouble is that I can not for the love of god get the framebuffer to work.
I use lilo as my bootloader, and i have this in it:
Code:
boot = /dev/hda
prompt
timeout = 05
image = /boot/vmlinuz
root = /dev/hda2
label = hda2
vga = normal # I can put 0x301 (640x480@256) here, but it'll complain about an unknown mode, and prompts me to select another mode
append="video=vesa:ywrap,mtrr"
read-only
However, when i boot with whatever videomode i select (a couple of new ones appear if i choose to scan), the framebuffer does not get started, however if i chose 132x50 as the videomode, the text goes over the edge of the screen.
Now, I'm pretty sure the grafics card is vesa2.0 compliant, as it says so in the spreadsheet. So that shouldn't be the problem.
The odd thing is, i had debian woody installed, and i saw the little penguin when i booted, so it has to be able to work. I just can't for the love of godmake it work. Argh.
My dmseg dosen't show anything relating to framebuffer or vesa, and it just prints that the console is 80x25 as normal.
Now. Does anyone have an idea as what could be the problem?
The slackware standard kernel does have support for framebuffer, so that shouldn't be the problem.
I hope one of you know Thanks in advance.
You misunderstood me, I use lilo for the laptop. I just mixed the setting up with the one from my GRUB config on my main workstation.
I have tried both without and with the "video=vesa:ywrap,mtrr" part, and no luck.
Seeing as it has worked with Debian woody 2.4.18-kernel, I would think that it is a kernel problem. And I'd rather not have to recompile the kernel, as it is a 75MHz, and it would take forever.
I should say that I have tried with both the 2.6 and 2.4 kernel of Slackware.

To be honest, I'm not quite sure how I would go about doing that.
I know how to compile the kernel, but what about modules etc. that need to be copied over?
I guess I should go and find out how to do that..
Also, you wouldnt happen to know what VESA module is needed?
I am looking at the /boot/config-ide-2.4.26 config file now, and that option is infact set..
That would mean it *should* work if I'm not mistaken. However, it just dosent.
