ATI Catalyst 9.8 Xorg freeze when idle
I have installed catalyst 9.8 in my arch system with radeon HD 4850. I suffer from Xorg freezes. I leave my computer for several minutes, then go back and screen is blank, and there is no signal. REISUB sequence does the work.
I used to use ati open source driver but now I need it to use HDMI and audio over HDMI.
Does anyone know the solution?
Sorry, because this might look like a zombie resurrection post, but it is not.
I had similar problem as the described one (ATI Radeon laptop + Compiz resulting in complete lock up after exactly 20 minutes idle time).
I searched the web in all directions and was unable to find any clue, but suddenly I resolved it. The problem was simple to deal with, but it took a long time to find out what's going on. As I forementioned I'm using Compiz. I ticked all the boxes in Compiz workarounds plugin, and the lock-up problem is gone.
I am writing, because I couldn't find any recipe anywhere on the internet, the problem persisted with every Catalyst version I could test (10.x, 11.x up to 11.9), so I think it might be useful for somebody having same issues.
So forgive me waking up a zombie thread. ;-)
