I’m currently installing Puppy Linux on an old computer, and everything is working fine, the resolution of the boot selections were looking ok, but the moment Puppy Linux boots the GUI, this happens!!! And I tried resizing from the GRUB terminal but it doesn’t work, please help me, thank you!!
Looks like it’s using a video mode the monitor doesn’t support, you’ll need to set the refresh rate as well as the resolution to ones that are supported. Likely candidates are 800x600@75hz or 1024x768@60hz, but it really depends on the monitor, check the manual if you can
thank you but I don’t have the manual, there is no information about this monitor online, I’m currently in BIOS, it’s American Megatrends.
If it’s a vga monitor you could probably plug it into a modern computer to see the available video modes in the display settings. Then on the old computer just change the video mode with xrandr in your xinit
