logitech 3200 mx choppy

Hi, Corey.

Thanks. That sounds like the batteries in your keyboard/mouse might be getting low.

Subject: [Question #74991]: logitech 3200 mx choppy

Hi. It seems recently, within the last week or two, I have started seeing a strange issue with my mouse and keyboard. I have a System76 Wild Dog with a Logitech 3200 MX. I'm on the latest version of Ubuntu, with all updates installed, and am still using Gnome as it was originally installed.

What's happening is that I'll be using my computer for a while with no issues, but then if I go away for an hour or more and return, both the mouse and keyboard perform horribly. Its more noticeable with the mouse. Instead of the pointer moving nice and smooth like it usually does, it moves choppy and jerky and doesn't feel like it keeps up with the mouse movements. The keyboard also seems to fall behind on the keystrokes, and occasionally misses key presses.

I thought it might be some issue with the screen saver or power management settings, but I tried disabling both of those and it still happens.

Also, I tried with another mouse that I have and it seems to work fine. Its just a cheapo USB wired mouse. It moves smooth, but the logitech still moves choppy.

Another weird aspect of this is that if I reboot everything starts working fine again. Its doesn't seem to happen again unless I go away for about an hour or more and then return. It only fixes it if I reboot. Its still choppy if I just logoff / logon.

I've checked the CPU load and its basically at 0 % (fully idle) and I have plenty of memory free. As far as I can tell, the computer is basically running fine except the mouse and keyboard are acting funny.

Ever seen this before, or have any suggestions on what may fix it?

Thanks,
- corey

Hi Tom. I don't think that's it. I already tried replacing them with new ones and I still get the same behaviour.

When your mouse gets choppy, if you leave it plugged in and plug in a wired mouse simultaneously, is the wired mouse choppy?

No, the wired mouse is fine in that case. Only the logitech mouse is choppy.

Also, I don't think I mentioned this above, but unplugging the mouse / keyboard, waiting a while, then plugging it back in doesn't help either. the only thing that helps is a reboot at this point.

The next time the problem occurs, shut the system down, reboot and go straight to System > Administration > System76 Driver > Support (tab) > Create (button). This will create an archive called logs.tar in your home directory. Please attach that archive to this thread.

I'll have a look at it and see what I can figure out.

Hi Tom. I finally got time to restart this morning. I restarted around 8, and the problem was gone, as before, and then I checked it around 8:45 and it was happening again, unfortunately, as expected. I immediately restarted and captured the logs as you said. I'm attaching them now (if I can figure out how).

Hi Tom. I just wanted to let you know that for some reason it stopped doing that for now. I'm not sure what happened. I think it may have started after my next to last update and then stopped after the most recent update. I don't think I have seen it after my last one anyway, and I thought it seemed like it started after the one before that. If it happens again I'll let you know, but hopefully it won't. Thanks. - corey
