nukedathlonman, to advise, given there are no debugging logs provided, developers are unable to work on this issue. Hence, please answer all of the following questions:
1) Could you please provide the full computer model as noted on the sticker of the computer itself (not from the Bug Description, or the result of a terminal command)? 2) To see if this is already resolved in Ubuntu, could you please test for this via http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? 3) If reproducible, could you please provide the missing information from https://help.ubuntu.com/community/DebuggingSystemCrash ? ** Description changed: 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). HOT TO REPRODUCE: Boot system and use normally or simply leave system alone. Blank screen will happen any time after x comes up. - EXPECTED RESULT: Screen doesn't blank unless a screen saver or power saver kicks in.
