vertical flashing lines at start - not booting


I installed the slack 13 in an old Toshiba Qosmio F10, and everything was ok...but then,like 2 or 3 days after,I got a display problem at boot time: the screen is flashing, in vertical lines,so I read 2 letters,and then the next 2 are flashing. And it can't boot. 'Loading the kernel' is the last message.

I tried booting from the slack cd, the huge.s, but I got the same.

The strange is that if I use an old (very old) live cd, Kurumim 4.0, a dead Debian-based Brazilian live-cd, it boots. And then I have the vertical lines in graphic mode, but the notebook works.

I think that this is a hardware problem, but since it works with an old debian livecd,I suppose it should also be bootable with Slack.


EDITED: Ok,I tried Ubuntu and it couldn't boot,but eith the 'grapfical safe mode' it booted.

Since I can't believe that even Ubuntu would boot, but not the Slack, I tried

# VESA frame buffer console @ 640x480x256
and it is the problem must be really hardware, the graphic card..Now I will try some others graphic definitions to see which one is the best

Often on a live cd there is an option noapic and noacpi and also vesafb these are all good options to try. With older hardware you have to search for a modern distribution that "fits" the machine or use an older version.
