Install on Old iMac

Volumio Community Forums

I have an old 2009 iMac that I tried installing Linux on but the graphics driver doesn’t work so I have to us nomodeset in the grub to make it work correctly. I thought I would install Volumio OS to see how that works but it does the same thing.

How can I get into the grub to set it to nomodeset?

Thanks

You will find the grub config in

/boot/efi/BOOT/grub.cfg
/boot/efi/BOOT/grub.tmpl

You need to modify both, let me know how it went.

Thank you gkkpch, but how do I access these files if when I boot from the thumb drive it I can’t read the setup? I’ve tried pushing shift key and also the escape key but wont go into boot menu.

I was able to find it on the two files thumb drive. Where do I insert NOMODESET into them?

@James_Boehm
In both files, look for the line “linux /linuz…” and add “nomodeset” at the end of it.
Unfortunately this may not work as in our initramfs, the graphics modules (ati/ intel/ nvidia) will be loaded with modeset=1, which could overrule whatever you have put on the command line.
You will need to try.

Just tried it and it didn’t work. Oh well, thank you for your help.
