Ok, i have tracked down the issue, for later reference, you can read it: https://www.linuxuprising.com/2018/08/how-to-enable-hardware-accelerated.html https://askubuntu.com/questions/1066105/how-to-install-amd-graphic-drivers-on-ubuntu-18-04
First of all, i have two cards in my machine HD5500 - R7 M260 (Topaz) Unfortunately ubuntu 18.04.1 does not pick up mesa at default, and it needs to be installed separately. It was installed before, but the official amd-gpu was a crap, i was not able to login, so i installed the linux and amd-gpu version back and forth, and with bionic beaver it just didn't happen automatically. When the ubuntu 18.04 upgrade was coming, my GPU card was disappeared very likely. I do remember that it was there on the lspci list. The post was right, vp8/vp9 hardware acceleration just not supported by my card (i had to instal the h264ify plugin), and i had to install latest dev chromium to make some progress. Now my CPU is not used at all, steady 6%, however neither ubuntu nor latest released chrome is not there yet to avoid tweaking. This youtube video is a very good test on 1080p, on chrome it simply kills my PC: https://www.youtube.com/watch?v=YqeW9_5kURI Although my CPU is not used at all, the lagging hasn't disappeared. I think when it's buffering the CPU goes high. (30-40%) I have read also about some VPN throttling. I'm not just using youtube. I have made the apport-collect ** Description changed: 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 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1803848 Title: Playing video on chrome freezes frequently (Too slow to catch up) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1803848/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
