View Full Version : [ubuntu] Blank screen when trying to install - nomodeset kernel panic

Hi people!
I've been trying to install Ubuntu 16.04 on my desktop but I can't seem to make it work. I've tried both with USB and DVD (both checked for intregrity) with no differences.

The USB/DVD boots, and it shows the UEFI selection screen (try Ubuntu, install, check disk, etc...). Whichever I choose, it goes straigth to a blank screen.

I've tried booting in BIOS (legacy) mode, and the only difference is I don't get the selection screen, just a brief purple screen with the little guy on the bottom, and then again, blank screen.

I've also tried with the following grub boot methods: nomodeset, nolapic, acpi=off, acpi_osi=(nothing after the =) and different combinations of them. Some combinations shows some processes going on, but no luck, some of them go to a kernel panic.

I've turned off secure boot, turned on IOMMU and tried different combinations of uefi or bios or whatever. The PC has only Windows 7 installed (I don't plan on keeping it) so there is no fast boot.

Here are my specs:
-Gigabyte Gigabyte GA-970A-D3P (no on-board video)
-AMD FX6300
-Sapphire RX460

Thank you!
