I've been running Fedora 25 on my machine for a couple weeks now. I happened to shut down the machine, and there were some software updates that automatically installed. After booting the next time though, my computer is running noticeably slower. Specifically, there is a significant lag for my mouse cursor, and also typing text seems like typing in molasses.

Is there any reason for this? Is there a way I can check my most recent software updates to see what the problem might be? Has anyone else running Fedora experienced this?

  • Did this slowdown happen for a longer period of time or was it just temporary? Might be just some background periodic job (e.g. updatedb) . Commented May 3, 2017 at 19:31
  • It's happening currently. I don't believe there are any residual processes running from the update, but how would I be able to determine if this is the result of a background process? Commented May 3, 2017 at 19:33

Fedora 25 is long end-of-life, mandatory upgrade. Current version is 31.

I would recommend starting with the following. Install "htop" if it is not already installed...

sudo dnf install htop

Then run it with

htop

This is an improvement over the old "top" - and you can look at CPU usage and see if any process (or process tree) is overusing the CPU and therefore slowing you down.

  • I dont' believe it's a process. In the boot menu I booted an older instance of Fedora 25 and it ran just fine. When I shut that instance down and updated the software however, I have the same problem. I have no idea what is causing this to be so sluggish... Commented May 7, 2017 at 21:39

A couple of bugs/issues and possible work arounds here and here.

  • These don't really seem to be related to the problem I described unless I'm missing something. Commented May 8, 2017 at 21:11
