I'm trying to install Ubuntu 18.04 (18.04.1 will try tomorrow) onto Acer Aspire A315-41-R8XR. I have unpacked iso file to my flash and booted to grub successfully, but when I select "Try Ubuntu", I just get black screen and that's all. I have also tried to select "Install Ubuntu", but I get many errors:
Windows 8.1 works fine, although it was already on the disk from another notebook, so, I think, it is not a power supply problem.
I've seen many such posts in the internet. It seems that people lost Ubuntu on Ryzen with Vega...
How to fix? May be use newer kernel? How to do it?
