Ubuntu Frame - not show display

Hi

I installed Ubuntu Core 18 (BIOS) on an HP PC (AMD64), with Radeon HD 6450/7450/8450 graphics card. Then I installed “ubuntu-frame”, but the graphic display does not appear. Below are the logs (snap logs ubuntu-frame). Note: I am new to Ubuntu Core and have no experience. Could someone help me?

Have you tried a newer release? Core 18 is rather old, you might want a newer release…

The PC is old and does not have an EFI BIOS. Do you know if there is a newer Ubuntu Core (22 or 24) that can boot without EFI?

Thanks

We used to have grub-pc in the gadget in the past, I haven’t checked if BIOS boot still works but how about you just write an Ubuntu Core image to a USB stick, switch your BIOS to USB booting and see if it gets to the kernel (it might fail later on if you already have an Ubuntu Core system on the internal disk but to prove BIOS boot reaching the kernel is enough)

Thanks for the feedback

I burned Ubuntu Core 22 to a Pendrive and the PC won’t start.

xzcat ubuntu-core-22-amd64.img.xz | dd of=/dev/sdg bs=4M status=progress; sync

I’ll burn Ubuntu Core to my PC’s HD and post a photo here.

Thanks!!

Hi,

I installed Ubuntu Core 22 and when I started the machine, the message below appeared.

Do you know if it is possible to create an Ubuntu Core 22 image that boots in BIOS mode?

Thanks!
