Are you sure the black screens are your only problem? I have problems with keyboard missing keypresses, touchpad doing strange stuff, hard drive performance, random crashes and caps-lock blinks, wifi required driver from github and manual setting of antenna. I ran sysbench and disk was performing at about 1.3mb/s speed only! There was at least 1 other person who wrote to my bug report that he was having the same problems.
With 4.8 hwe kernel, it does not even boot anymore. Looking at all the bug reports, the problems seem to be only getting worse and worse with updates. It is almost like linux is trying to irradicate AMD machines... Here is my bug report for the hard drive performance, are you able to replicate it? https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1616830 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1642078 Title: Black screen at startup on Carrizo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1642078/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
