Ah! Your kernel log mentions the AMD video decoder here: [ 1223.799908] [drm] UVD initialized successfully.
So it's possible that's the cause of the main problem. Can you please reintroduce the bug and run 'vainfo'? Does 'vainfo' report different information after you switch your BIOS? If that is the problem then the workaround should be: sudo apt remove mesa-va-drivers -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gstreamer1.0 in Ubuntu. https://bugs.launchpad.net/bugs/1774915 Title: Video freezes and stutters when using totem (audio continues fine) Status in gnome-shell package in Ubuntu: Incomplete Status in gstreamer1.0 package in Ubuntu: Incomplete Status in mesa package in Ubuntu: Incomplete Bug description: Advised to file a bug report after posting on "Call for testing: Video playback in 18.04". Running 18.04 LTS as fresh install (not upgraded from previous version - older version still installed in separate partition). Xorg session. System: HP Pavillion DV7 (lm726av) - Intel Core i7 2630 processor, integrated Intel video Playing any local video file (regardless of video format - flv, mp4, avi), the video will randomly lag in playback. Audio is not affected, it plays back correctly. Very occasional lags in browsers (Firefox and Chrome) on pages with a lot of active graphics (flash or HTML5). Browser lags significantly improved after installing synaptic driver for touchpad operation (I have no idea why this would affect video playback - I simply note that it happened). I can pick a random video on YouTube and watch it in Firefox or Chrome without lag (even full-screen). However, if I grab a local copy of the video (using, for instance, Clipgrab) and play it using Totem, I get lag. I was also advised to try using mpv - I still get lag in mpv, although not as pronounced. tracy@tracy-hp:~$ sudo apt-cache policy totem [sudo] password for tracy: totem: Installed: 3.26.0-0ubuntu6 Candidate: 3.26.0-0ubuntu6 Version table: *** 3.26.0-0ubuntu6 500 500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 100 /var/lib/dpkg/status I was also asked to include output of lspci -k - shown below: tracy@tracy-hp:~$ lspci -k 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) Subsystem: Hewlett-Packard Company 2nd Generation Core Processor Family DRAM Controller 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) Kernel driver in use: pcieport Kernel modules: shpchp 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) Subsystem: Hewlett-Packard Company 2nd Generation Core Processor Family Integrated Graphics Controller Kernel driver in use: i915 Kernel modules: i915 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family MEI Controller Kernel driver in use: mei_me Kernel modules: mei_me 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family USB Enhanced Host Controller Kernel driver in use: ehci-pci 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family High Definition Audio Controller Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) Kernel driver in use: pcieport Kernel modules: shpchp 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5) Kernel driver in use: pcieport Kernel modules: shpchp 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5) Kernel driver in use: pcieport Kernel modules: shpchp 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) Kernel driver in use: pcieport Kernel modules: shpchp 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family USB Enhanced Host Controller Kernel driver in use: ehci-pci 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05) Subsystem: Hewlett-Packard Company HM65 Express Chipset Family LPC Controller Kernel driver in use: lpc_ich Kernel modules: lpc_ich 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family 6 port Mobile SATA AHCI Controller Kernel driver in use: ahci Kernel modules: ahci 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) Subsystem: Hewlett-Packard Company 6 Series/C200 Series Chipset Family SMBus Controller Kernel modules: i2c_i801 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
