** Description changed: - Summery: I'm having a hard time tracing this down. I updated to Kubuntu - 16.04 (from Kubuntu 15.10 - that was using the Linux Crimson 15.12 - driver) a couple days ago on my notebook (HP Pavilion, A10-8700P APU), - and ever since I've been having random black screens. I started - debugging the driver, then thought it might be a DPMS issue (it's not - - I have DPMS fully disabled currently), and now I'm back to debugging the - driver. I don't have any remnants of the former closed Crimson display - driver and never had an xorg.conf file (I made a small one that I'm - using at the moment consisting of only a server layout to ensure screen - savers, DPMS, etc are all off). The Black screen can happen any time - from the login screen until hours later. I can ssh into the system to - shut it down. And just discovered that if I unplug the system from it's - power brick, I can close the lid - the system will goto sleep. When I - flip the screen back up, the system wakes up and the screen works again - for 1-2 minutes. I don't see any errors in the log files (well, outside - some nasty looking ACAPI errors in dmesg). + I'm having a hard time tracing this down.
