> 1. Is the high CPU usage sustained when you're not doing anything? No.
> 2. Is the CPU usage only when using a mouse, or does it also occur when using a keyboard? In both cases. For example, Xorg's CPU usage jumps to 85% on my machine when I continuously switch once per second from one terminal window to another, regardless of the means (mouse or ALT+TAB). On the other hand, merely typing (albeit fast) into a terminal window leads to a much lesser usage by Xorg (around 10%). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879042 Title: [radeon] Xorg high CPU usage and stuttering on ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1879042/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
