Blank screen after grub but TC loads ok

(1/1)

Hi,

I'm having display issues with my custom build based off TinyCorePure64-13.1.iso

The grub screen looks fine, then when the kernel loads, the screen goes blank. At this point, if I hit the up/down arrow on the keyboard I get beeps.

I know TC is loaded ok because I installed ssh server on this image and I can ssh in ok.

I looked for the "Above 4G decoding" setting in the bios but it doesn't have it.

I've tested it on 2 different hosts with the same issue. They are both those little NUC boxes you can get off Aliexpress (such as https://www.aliexpress.us/item/3256804116114245.html)

I use TinyCore as a USB installer OS, so I have a Packer built custom Ubuntu raw image embedded into the Tinycore image which I then "dd" to the NVME disk on the NUC.
This process works fine via ssh and then the custom Ubuntu loads ok, and the keyboard/display work no problem with the custom Ubuntu.

I also tried the stock TinyCorePure64-13.1.iso flashed to USB (Etcher) and I get the same issue. Just no display after the grub menu and beeps on arrow up/down.

Am I missing some drivers for this little NUC device that I need to add to my custom TC image? Any idea how to debug further?

Cheers,

Jason

If you hit the  Enter  key a couple of times, do you get a command prompt?

Hi Rich,

I ended up just needing to install "xf86-video-intel". And then add "modprobe i915" to bootlocal.sh
   
Cheers,
