I'm using Lubuntu 18.04 LTS on an 10 year old Acer laptop. It's of course slower than modern notebooks, but still works like a reliable old mule.
Only issue I'm having is the keyboard. Certain keys won't work, but it's sort of irregular which ones, which makes me think it's not a hardware issue.
As I'm typing this the i, o, 2, 4, 5, 7 and Return keys are not working. Oftentimes the Space and sometimes the Enter keys don't work either, but then start to work after the laptop has been running for a while.
Sometimes, after the laptop has been running for a while, suddenly all keys work for a brief time, then those certain keys stop working again.
I tried running:
sudo apt-get --purge autoremove xserver-xorg-input-all sudo apt-get install xserver-xorg-input-all
But it didn't help. I am helping myself with the Onboard keyboard application, but it's a pain.
Does anybody know this issue or have any idea what I could try to solve this?
