i had installed ubuntu along with my windows 8 in my dell laptop.after loggin into it my cursor started moving on its owm.it always remained at one particular position on the screen.even if changed it it went back to that position.after some time it was functioning normally again.but this problem was occurring regularly each time i logged in.later on i replaced my ubuntu with linux mint(just because i wanted to use mint).i face the same issues with my mint as well.my windows works fine.anyone knows what i should do?

Could it just be a cable problem ie: cable too short??

The second less savoury thing is someone may be hacking you remotely via bluetooth or wireless. Most laptops these days have both unfortunately. Turning off these, and discovery, scanning type problems may not fix it as you can be attacked at the device level such as BD_ADDR. Joshua Wright wrote about this. Laptops on an aeroplane with Flight Mode on and BT and wifi off, scanning off etc can be hacked this way.

Best bet is to setup a VPN with a company such as Torguard or similar - Google. Also install wireless and bluetooth connection monitoring tools. Just browse your Synaptic Manager for these.

I'm curious about this because I see it too often in LXQT. I don't know the cause but would like to. There is one work around besides using an external mouse and not the track pad. What works for me sometimes is to suspend the machine, wait a bit, and then resume. I only see the problem with the track pad not with bluetooth mice or USB mice.

I had a system that if you booted with a gps puck attached, it registered it as a serial mouse. So, the cursor jumped all over.
