    Fedora 28 new install, severe USB keyboard & mouse lag

    I'm installing Fedora 28.1.1, after verifying the checksum of the download, on a brand new server with a Xeon E3-1275 v6 CPU, 64GB of 2400 Unbuffered ECC DDR4, Intel P630 integrated UHD Graphics, and a 480GB SSD, all components approved by the server board manufacturer.

    First, I tried Ubuntu 18.04.1 LTS, which installed AOK from its checksummed LiveUSB. There was no lag.

    Next, I tried Fedora Server 28.1.1, which went blank shortly after booting from its checksummed LiveUSB, generated by the Fedora LiveUSB Writer. I got the same result with Fedora Workstation 29.1.2.

    Then, I tried Fedora Workstation 28.1.1, after turning off Quiet Boot in the BIOS/Setup. It very slowly booted, and I was able to install Fedora on the SSD. But, after rebooting and login, I found the USB keyboard was very slow and also stuttered on about 1/4 of the keypresses, and the mouse was very slow and jerky. Replacing the keyboard and mouse with known good peripherals did not help.

    What logs should I look for, and where would I find them in Fedora? What should I pay attention to in those logs?

    What was the solution? I'm getting significant mouse and keyboard lags after fresh install of Fedora 30

    Would you mind providing more details? I have a similar issue for Fedora 30 with a Xeon CPU.
