    Computer lags, mouse freezes

    My desktop lags and slows, mouse freezes and sputters. This seems to happen when libreoffice is open and when many things are happening on screen, or when programs are opening. It's hard to figure out what specifically is happening. I feel it started after I upgraded to 19.10 (upgraded from 19.04).

    I have a Dells Desktop Inspiron 3847 (Inspiron 3847)
    Ubuntu 19.10 dual boot with windows
    Intel 3.10
    Gnome: 3.34.2
    64 bit
    1.0 TB

    How much RAM?
    Does the desktop work well under Windows?
    What version of Windows?
    Integrated or discrete video card?

    like the last poster asked, how much RAM do you have ??
    also, does the mouse work correctly under Windows ??

    if you have inxi installed, open a terminal & type this

    Code:
    inxi -I
    post the output in your reply, using code tags is preferred

    if you don't have inxi, use sudo apt-get install inxi and then repeat the above...

    1 more thing to consider is your mouse cable, if it has 1...just had to replace my mouse due to a bad cable that was causing
    the very symptoms you are seeing...

    Yes, it works fine under windows.
    I have 3.8 RAM (from the About screen)

    It seems like the whole CPU bogs down and is represented by the mouse activity. Or, some process is running the background, I've looked at the CPU usage and doesn't seem to be anything abnormal.

    I'll install the inxi and run that when I can.

    Thanks,

    D

    The reason for that is mainly because you haven't provided any useful hardware specifications, especially the graphics because in all likelihood it needs drivers. BTW, the command
    Code:
    inxi -I
    (with an uppercase "i") is exactly for that.

    dennis@dennisDesktopDual:~$ inxi -I
    Info:
    Processes: 224 Uptime: 3d 23h 20m Memory: 3.76 GiB used: 2.54 GiB (67.4%)
    Shell: bash inxi: 3.0.36

    That is the output of the request (same as above). I'm more than happy to provide any information that I can to help you help me. Let me know what you need and I will provide it. I'm very grateful for the help, I've done all I've been asked
