[Bug 1868009] Re: Xorg high CPU usage and stuttering with the Nvidia driver
Si Dedman, Please log your own separate bug by running: ubuntu-bug nvidia-driver-440 Best I can tell this one is probably a hardware/connection fault and not a software bug. Maybe. ** Summary changed: - Xorg high CPU usage and stuttering with the Nvidia driver + Xorg high CPU usage and stuttering with the Nvidia driver (TCL TV continuously loses and regains HDMI connection) ** Information type changed from Public to Private -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868009 Title: Xorg high CPU usage and stuttering with the Nvidia driver (TCL TV continuously loses and regains HDMI connection) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1868009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1868009] Re: Xorg high CPU usage and stuttering with the Nvidia driver
Hi folks, Similar story here, as detailed in comments in this thread: https://askubuntu.com/questions/1184366/lagging-after-update-to-19-10-from-19-04/1184571?noredirect=1#comment2050464_1184571 Then my own post: https://askubuntu.com/questions/1219696/video-lag-after-updating-to-19-10-from-19-04 But no improvements as yet. Summary of above threads: update from 19.04 to 19.10 started the issue, the nvidia driver is probably the problem since various kernel changes haven't helped (currently using 5.6.1). I can't use the nouveau/xorg open driver as it's limited to 1024*768, and an xrandr bug prevents adding new modes.

I've also noticed the bug is worse in some programs than others. If I hold down the arrow key in libreoffice, it'll scroll prettymuch normally. Whereas if I do the same in RStudio (IDE) it'll lag before moving, then pause intermittently. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868009 Title: Xorg high CPU usage and stuttering with the Nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1868009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It's probably a loose or poor quality HDMI connection so try a different cable to the same TV. Or try the same cable to a different TV. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868009 Title: Xorg high CPU usage and stuttering with the Nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1868009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1868009] Re: Xorg high CPU usage and stuttering with the Nvidia driver
I can confirm that unplugging my TCL TV HDMI connection gets rid of the problem. How strange that it would be reconnecting multiple times per second. Any thoughts on why or how to proceed? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868009 Title: Xorg high CPU usage and stuttering with the Nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1868009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also your Xorg log shows the monitor is being repeatedly reconnected a few times per second: [ 8306.094] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): connected [ 8306.094] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): Internal TMDS [ 8306.094] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): 600.0 MHz maximum pixel clock [ 8306.094] (--) NVIDIA(GPU-0): [ 8306.686] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): connected [ 8306.686] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): Internal TMDS [ 8306.686] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): 600.0 MHz maximum pixel clock [ 8306.686] (--) NVIDIA(GPU-0): [ 8306.775] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): connected [ 8306.775] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): Internal TMDS [ 8306.775] (--) NVIDIA(GPU-0): Tech Concepts 55S425 (DFP-1): 600.0 MHz maximum pixel clock In case this is due to a bad connection, please unplug and replug the monitor.
