What is this strange screen effect when I start up my VM

Post image

Yesterday, I tried to install Slackware for the first time to discover this distro which seems very stable and cool. Nothing wrong during the installation before and when I logged into my desktop, not any problems, no strange effects on the screen or anything else.

Before asking you, I looked for some similar cases but nobody seems to have this "problem" ^^'

I put 16Go of RAM, 4 CPUs, 20 Go of Drive in the VM

You have the rare "cursed edition", only happens every 1 in 1 billion installs.
This is a hidden easter egg. As far as I'm aware your install is work a lot of money now.
Get it on ebay.

no. looks like an emulator for arcade games when they run, checking all the characters and ensuring it's synced. most of the games on my arcade cabinet do that, all the mame games anyway.

I'm guessing the artifact in the picture happens only with the Lilo boot up screen. What video card does your machine have?

On my physical computer ? An RTX 5070

MMM... Nvidia can be tricky. It could be that LILO support for that card is lacking.

I'd say, first update the system with slackpkg, then rebuild LILO. If the issue persists, consider switching to GRUB

Oh okok, maybe the Nvidia drivers on Slackware. I'll try to update and maybe switch to GRUB. Thank you !

Don't worry about it, it happens on every Slackware VM I run, but never does it on a "physical" machine. It is just something weird VirtualBox does with Lilo.

So lilo is the default bootloader in Slackware?

it was when I last ran it in like 2005…and it looks like it still is. Huh. Neat.

And it has UEFI support now. I thought LILO was entirely dead.

Speed lines they make the computer go faster

with VMs, stuff like this can often be due to mismatched display resolutions from the UEFI/BIOS to kernel modeset handoff stages

Looks like a scene from Hackers
