(please see the attached chart) Steps (to hopefulle reproduce): =============================== - start pc - do some usual work for a couple of hours - hibernate - wake up - do some usual work for a couple of hours - hibernate - wake up ( you might need more repetitions here) - do some usual work for a couple of hours - plug in USB microphone Actual: - Xorg has high CPU usage Expected: - Xorg has usual CPU usage Remarks ========= I could not safely reproduce this behaviour on purpose simply by starting and hibernating. But I experience it on a week to week basis. I'm not suspending or some kind of suspend+hibernate. It's pure hibernation I experience this problem, I think, in 16 (started here), (never tried 17), 18, 19.10 I used perftop with flamegraph the other day. It revealed - DeletePassiveGrabFromList with 3 ~ 5% - ResourceClientBits: around 5% - GrabMatchesSecond: 3 ~ 5% - trace_raw_output_kvm_inj_virq: around 7 ~ 8% System ======= lsb_release -rd ------------------- Description: Ubuntu 19.10 Release: 19.10 apt-cache policy xorg ---------------------- xorg: Installed: 1:7.7+19ubuntu12 Candidate: 1:7.7+19ubuntu12 Version table: *** 1:7.7+19ubuntu12 500 500 http://archive.ubuntu.com/ubuntu eoan/main amd64 Packages 100 /var/lib/dpkg/status Misc ---- - 12GB RAM - Core i5 4 cores Debugging ---------- I can help collecting data, but I need assistance ProblemType: Bug DistroRelease: Ubuntu 19.10 Package: xorg 1:7.7+19ubuntu12 ProcVersionSignature: Ubuntu 5.3.0-40.32-generic 5.3.18 Uname: Linux 5.3.0-40-generic x86_64 ApportVersion: 2.20.11-0ubuntu8.8 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: XFCE Date: Tue Apr 28 17:29:02 2020 DistUpgraded: 2019-12-01 10:19:03,497 ERROR got error from PostInstallScript ./xorg_fix_proprietary.py (g-exec-error-quark: Failed to execute child process “./xorg_fix_proprietary.py” (No such file or directory) (8)) DistroCodename: eoan DistroVariant: ubuntu DkmsStatus: virtualbox, 6.0.14, 5.3.0-40-generic, x86_64: installed virtualbox, 6.0.14, 5.3.0-46-generic, x86_64: installed ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation UHD Graphics 620 [8086:5917] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Fujitsu Limited.
