After installing Fedora 29 (and using Fedora 28 without problems). I find that every 5 second or so, the mouse an the keyboard typing freeze for a fraction of a second (which is very annoying). I see some errors in dmesg but not something that repeats every few second for example.

Is there a tool to see what could be freezing the input devices?

Is it known if Fedora 29 is producing a problem?


After some research I see that what freezes is not the mouse or the keyboard, but the display I have an onboard intel video card and didn't install anything fancy. I tested it by running glxgear and watching a video of glxgears on youtube.

This is the journalctl | tail output, in case it helps:

EDIT 2: This is not a hardware problem. I just reinstalled Fedora 29 and I don't see the problem.

I cannot 100% confirm but it seems that this is a problem with Wayland, after turning off Wayland the lag dissapeared.

Anyway, I was planning to disable Wayland due to this bug: https://ask.fedoraproject.org/en/ques...


Updated 2: The problem persists, the display still freezes when using Xorg, the only different is that the mouse cursor is not subject to the freeze.

Now that you're not using Wayland, take a look at the file ~/.xsession-errors, which contains every error produced by your current session. Most of what you'll see won't have anything to do with your issue, but you may see something coming up repeatedly, and if so, let us know because it's probably related.

mmm, I don't see a ~/.xsession-errors file. Looks like a hardware problem, I am going to reinstall Fedora 29 after a deadline I have.

You're not going to see it or any other dot file (Files who's name starts with a dot are hidden by default.) unless you turn on Show Hidden Files.

@sideburns, I know how to check for hidden files (show hidden files or use ls -all). There still no ~/.xsession-errors. The problem persists after one or two kernel updates, this looks like a very low level hardware/kernel problem.
