Hello all,
The following problem appeared gradually, not from the beginning that i installed 16.04. It appeared while I was doing updates, around 1 month ago.
While I am working on the laptop, the external usb mouse and keyboard stop responding completely, e.g. the cursor freezes. Laptop's keyboard operates fine always, and also always (almost) the laptop's touchpad.
Temporary workaround is suspending the system, then turn-it on again. Usually, everything works, for some time. Then again...I have to suspend and the story goes on.
system's details are:
- OS: Ubuntu Mate 16.04.4 LTS
- laptop: DELL latitude e6420
- kernel: 4.13.0-36-generic
- VM VirtualBox
Any solution on this?
Regarding other devices that I have tried on usb, e.g. usb stick, seem to work without any issues.
Thanks,
kpapadim
