Intermittently Unresponsive Mouse

CentOS 8 Comments

I am using the Mate desktop on CentOS 7 and have found that the mouse intermittently becomes unresponsive for a few seconds, typically no more than 3-5 seconds. I do not remember seeing that when I used the regular Gnome desktop on CentOS 6 but I could misremember. The machine is fast and uses a dual-monitor setup with the native nVidia graphics driver.

Is this really to be expected? I thought this was not an issue on Linux or maybe I am engaging in wishful thinking…

  • Hello H,

    Do you reproduce the same issue w/ another hardware (mouse or trackpad if it’s a laptop).

    Does `tail -F /var/log/messages` show anything special while this is happening?

    Would be nice to check the resources consumption too, in order to see it those lags correspond to high-activity peaks.

    Regards,

  • How is the mouse connected — ps/2, usb, bluetooth, something else
    (e.g., mouse-specific dongle)?

    I use a touchpad that’s built into my usb-connected keyboard and don’t encounter mouse latency issues with c7/mate.

  • My mouse lag tends to correspond to low battery or exceeding the 2-3 ft range of wireless (i.e. I kick back on my chair). Assuming it is wireless. Not much info on hw.

  • I think you were right. I moved the computer a little bit closer and no longer have the problem. It is a Bluetooth mouse, I did not know that they were that sensitive to the distance…

    Thank you.

  • Bluetooth in absence of other 2.4Ghz  interference (cough, wifi) can work reasonably well at like 20-30 feet.    if there’s active nearby wifi on 2.4Ghz, forget it, much closer.

  • If there is any other sort of 2.4 GHz device, then it will be even worse. Such devices that poison this unlicensed band can be:

    1. microwave oven
    2. 2.4 GHz “cordless” phone (the one that is using ground line, and had cordless hand unit talking with base station on 2.4 GHz band)
    3. other 2.4 GHz devices (like music center with wireless links) may be less nasty than the above two, they pretty much will be close to WiFi network units

    You also may have neighbor behind the wall with the stuff like above, or even worse: your place maybe in the path of the beam between two places using 2.4 GHz connection channel (the last is less likely, as they usually like not to have any obstructions along the beam, but you may still be hit by the periphery of their beam).

    Incidentally, there are higher power bluetooth USB adapters that are capable to provide about 50 feet range coverage…

  • if your bluetooth is courtesy of a USB dongle, you could get a short USB cable to extend its reach nearer your mouse. if, OTOH it is a builtin bluetooth thingy, then, well, sorry I wasted your time! :)
