[Bug 1756877] Re: Input latency in 18.04
That's surprising, and is the opposite of what I would expect. Are you saying the high power usage occurs _with) nvidia-driver-390 installed? Anyway, back on the original "latency" problem this bug is about... It sounds like this is actually an output latency problem, related to the nouveau driver and possibly related to the recurring kernel messages: [80940.257342] nouveau :02:00.0: bus: MMIO write of 0002 FAULT at 4188ac [ IBUS ] ** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu) ** Summary changed: - Input latency in 18.04 + High visual latency in 18.04 when using nouveau ** Changed in: linux (Ubuntu) Status: Incomplete => New ** Tags added: nouveau performance -- 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/1756877 Title: High visual latency in 18.04 when using nouveau To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1756877/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Also your kernel log (dmesg.txt) is showing a lot of errors from the nouveau graphics driver.

Other configuration i have tried is with or without an external screen.
