I know you think it's probably insane to try and use a 266 MHz and 76MB laptop in 2017, and I think the same, but insane or not, I wanna use it, for "making" something on that laptop is a project I do with my little bro. I get to teach him linux while I learn a thing or two at the same time.
First, I tried installing Slitaz linux, but it doesn't work. This laptop's graphics card uses the neomagic chipset. I tried Slitaz with Xorg, but no matter what I did Xorg didn't start. I'm not an expert in linux, I started using linux about 5 months ago, so I seek help.
After a few more tries I managed to get Slitaz 3.0 to load the display, but I got a very weird result which I couldn't fix. Now I tried with DSL and I got the same result. A display that looks like this:

Can you help me fix this? Thank you!
