Hi Christopher- I was actually still running Ubuntu 12.04. It was last July. When I did last summer's firmware update for Linux kernel drivers I got a black screen. It would not roll back to a previous version. ========== I then tried the 14.04 as a fresh install and only got snow with my dual Radeon HD 6570. My motherboard is Asus M5A97 R2.0 AMD 970 ATX MB. Clearly this is itself a major bug. It is uncomplicated. It does not work. ========== A black hole problem like these yields little post crash info. Unfortunately, I migrated to Xubuntu due to lack of response to this issue, which occurred occurred a year ago. I still hold back the firmware for Linux kernel drivers update on this system, which update precipitated the problem. I became extremely agitated and made a fairly incoherent bug report. But I do hope someone figures it out before I have to migrate to another distro entirely , Sincerely. Glenn J Tison > Date: Tue, 26 May 2015 03:28:06 +0000 > From:
