Left arrow pushes by itself

English Hardware
1

I had OpenSuse 13.2 and suddenly left arrow started to push down by itself every about 1-2 second. It happens in KDE but not in BIOS. Solutions I have already tried:

  • Restart computer without keyboard plugged in (still left arrow bug even without keyboard plugged in)
  • Restart computer without mouse plugged in
  • Tried different USB ports for keyboard/mouse
  • Bios reset
  • And here comes the weird part: I did fresh LEAP 42.1 install and same problem occured instantly. (formatted whole hard drive for install)

Next thing I’ve planned to try is to buy a new keyboard and try fresh install again.

I’m still quite new with linux, so I don’t really know what I should try next…

I ran grep -i “keyboard” /var/log/Xorg.0.log :

Well, when you think it is hardware (also my guess for what it is worth), connecting another one (new or not) might help in at least your problem solving. However I do not see any case for installing the system anew. What do you suppose it would repair?

Thanks for answer, I’ll try next with another keyboard then. I reinstalled system because I thought that maybe I installed some system update which affected to keyboard. And why I’m planning to do fresh install again with new keyboard is because I think that maybe default keyboard drivers changes according to which keyboard is plugged in at installation. That’s just a wild guess tho…

LOL that is in no way needed. You can of course reinstall as much as you like but it won’t change anything. That is not how Linux works.

You’ve been Windows washed :X

Yeah, I had to reinstall Windows about every three months to keep it smooth and less full of errors…

Anyway, I surprisingly found solution to my problem. It was old and unused pci TV card which was recognized as keyboard. TV card probably sent “left arrow tick” to system.

Yep remove any unused hardware jut because :stuck_out_tongue:
