High CPU by Xorg on Linux Mint Mate and Ubuntu + Mate
Hi,
i had a problem with both Linux Mint Mate 17.3 and Ubuntu 16.04 + Mate desktop (different machines). After some time (from minutes to hours) the Xorg process would jump to high cpu (100% of 1 thread) and never slowing down again.
After disabling several programs/extensions/add-ons i found that disabling 'Compositing' in the Windows Manager solved the issue.
This can be configured in the Desktop Settings -> Windows.
The Linux Mint was running the marco window manager. For ubuntu i can't tell.
That's odd. It didn't occur with older versions of Mint. So what are specs of the other machine, and which ones are running Ubuntu MATE and Mint 17.3 MATE?
If it's the same hardware, and wasn't present in older versions of Mint and Ubuntu, it may be a software bug.
What happens when you try running another GTK based fat free DE like XFCE? Or just another DE/window manager in general? And with the Marco (MATE's Metacity) window manager?
i don't see how the behavior can be consistent on 3 completely different (different distro, different hardware) machines, so can you give more detail?
generally and from what info you provided, i can say that hardware accelaration on newer intel chips/gpus is not working perfectly yet; that COULD explain why disabling compositing helps.
