I have identified at power management at least 5 critical bug in the last 3 years which hasn't been solved. For example one year before my battery lifetime showed 4 hours, now just 2 hours. 2 years before 2 hours. So in the middle of the time frame something has been fixed and after that the fix has been reverted.
I have removed also the diagram from my top bar, which shows the cpu usage. (as I have read forums, that 120HZ might kill something in Ubuntu while animating - that one solved the system-ud hog - as a process hasn't locked something right away, with a delayed chrome start, the system was more stable) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1803848 Title: Playing video on chrome freezes frequently (Too slow to catch up) Status in chromium-browser package in Ubuntu: Confirmed Bug description: Latest update of ubuntu made some strange problems: system-udev made a high CPU usage on nvidia, i have made a restart on the udev, thus i have decided to bleach it and run the following commands: sudo systemctl start systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket sudo systemctl stop systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket It solved some of the flickering problem, but it did not disappear. I'm running on 120Hz, sometimes the screen resolution has been changed so quickly on boot, that i have noticed lines at the bottom of my screen. (like in a bad monitor) Why ubuntu needs to change that so frequently, it just amortize the graphics card. The real issue is that my video playback youtube / scolling main site of origo.hu (local news portal) etc. flickering frequently. It is too slow to catch up. Suddenly stops, and after 2-3 seconds it restarts. It only happens on chrome seems to me, and does not happen when i disabling gpu. https://bugs.chromium.org/p/chromium/issues/detail?id=906861#c8 As a matter of fact, my CPU usage is not that much with or without gpu, so on gnome-shell some optimization needs to happen. Why i have GPU acceleration, if the gnome-shell swallows the benefit? On firefeox it does not happen, but the WebConsole CPU usage is 3 times more than in chrome. (70-80% on a full hd video, which is burning up all my cpu time, so it cannot be the solution to jump to firefox) Other thing is that the cooler less frequently making noise without gpu, even if the CPU has got higher load. If the cooler is running on high frequency, i hardly able to work. The non-accelerated Chrome CPU usage is half of the accelerated firefox cpu usage. I have posted the problem on both side, because i have a feeling there is problem at the middle, how ubuntu and chrome corporates with each other. Visual studio code also has some high CPU problem while scrolling, cooler makes noise. To me seems that it does matter whether the gpu makes the heat or the cpu regarding to cooling insensitivity. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2017-08-07 (471 days ago) InstallationMedia: Ubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) Package: gnome-shell 3.28.3-0ubuntu0.18.04.3 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.15.0-39.42-generic 4.15.18 Tags: bionic third-party-packages Uname: Linux 4.15.0-39-generic x86_64 UpgradeStatus: Upgraded to bionic on 2018-08-24 (89 days ago) UserGroups: adm cdrom dip docker lpadmin plugdev sambashare sudo vboxusers video wireshark _MarkForUpload: True --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DisplayManager: gdm3 DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2017-08-07 (471 days ago) InstallationMedia: Ubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) Package: gnome-shell 3.28.3-0ubuntu0.18.04.3 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.15.0-39.42-generic 4.15.18 Tags: bionic third-party-packages Uname: Linux 4.15.0-39-generic x86_64 UpgradeStatus: Upgraded to bionic on 2018-08-24 (89 days ago) UserGroups: adm cdrom dip docker lpadmin plugdev sambashare sudo vboxusers video wireshark _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1803848/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
