Public bug reported: Hi guys-
I hope I am in the right place, or at least a place where it can be understood to be properly placed. I will start with the basic needs: $ lsb_release -rd Description: Ubuntu Bionic Beaver (development branch) Release: 18.04 $ apt-cache policy mate-settings-daemon mate-settings-daemon: Installed: 1.20.1-2ubuntu1 Candidate: 1.20.1-2ubuntu1 Version table: *** 1.20.1-2ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages 100 /var/lib/dpkg/status What is happening is that after a random period of time, my media player will open up, persist upon staying open and I will see a spike to 100% CPU utilization. I have found that the following are involved somehow, as ending the tasks has a significant impact. 1. mate-settings-daemon (this often will appear as unresponsive when trying to reboot to fix the issue) 2. at-spi-bus-launcher 3. at-spi2-registryd I have looked into the media player as the issue. My default is Audacious and that is the one it opened. I simply renamed audacious in /usr/bin to audacious2. When I do this, it opened VLC instead, leaving the problem still there. So I have sort of eliminated the actual/specific media player. In my xsession-errors, I get the following WHILE the problem is active: Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x4000026 (Audacious) Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed. repeated over and over, continuously. With some research, I have seen similar issues in the past. Per those issues, I have found that removing the execute ability from file "at-spi2-registryd" has reduced this issue, but has not stopped it from happening. This "fix" has also introduced many other entries into the xsession-errors log. This was an issue from when I first installed, but after some updates it went away. It as of 2 days ago after running updates has come back strong. The above is my experience since it has come back and what I have done to resolve. I am using MATE. Also, when this issue is active, I lose keyboard ability to type in fields (like this one) and some menus are not functional, like file, edit, etc. This includes the main system menu, like applications and places. Only other thing I can add is that I have found a temporary fix as follows... Click ctrl-alt-F1. Login, then click ctrl-alt-F7 to return to the GUI. This will most times stop the issue where I can actually close the media player without it reappearing right away, and returning functionality to keyboard and menus, etc... the return to "normal". It will then happen again, at what appears to be at random. ** Affects: mate-settings-daemon (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766043 Title: High CPU and opening of media player To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mate-settings-daemon/+bug/1766043/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
