[Bug 2051383] Re: gnome-shell high CPU utilization when moving a high frequency mouse
Thanks, yes I'm aware Desktop Icons NG is part of the problem here. I thought we already had a bug to track that but I can't find it so will include that here. ** Also affects: gnome-shell-extension-desktop-icons-ng (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/2051383 Title: gnome-shell high CPU utilization when moving a high frequency mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2051383] Re: gnome-shell high CPU utilization when moving a high frequency mouse
To answer your first question: I'm testing on a freshly booted system with no applications running. Regarding extensions: After I disable the Desktop Icons NG extension (appears to be one of the built-ins), peak CPU usage for gnome-shell goes from ~55% to ~35% when moving over an empty desktop. When moving over an application such as gnome-terminal, CPU usage for gnome-shell increases to ~60% both with and without this extension (and also gnome-terminal itself consumes about 25%). Besides that I have Ubuntu Dock and Ubuntu AppIndicators - disabling them didn't affect CPU usage. evtest output attached. ** Attachment added: "evtest.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+attachment/5749814/+files/evtest.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051383 Title: gnome-shell high CPU utilization when moving a high frequency mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If you run 'sudo evtest', select the mouse and then wiggle it, what kind of output do you see? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051383 Title: gnome-shell high CPU utilization when moving a high frequency mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2051383] Re: gnome-shell high CPU utilization when moving a high frequency mouse
This is strange. I've been profiling gnome-shell 42 on jammy and gnome- shell 46 on noble. Neither have the bug, at least not with my lowly 1000Hz mice (which seems to be the same polling rate as the Razer DeathAdder V2). The profile in comment #18 is intriguing because it very clearly shows meta_idle_manager_reset_idle_time is the problem for you. But when I profile my own systems, that function accounts for under 1% of gnome- shell's time. Can you think of anything you have like an extension or application running that might seek to disable screensavers and prevent screen blanking? A browser or video player maybe? ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051383 Title: gnome-shell high CPU utilization when moving a high frequency mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
