I have a VAIO VJF153F11X with 18.10 installed. After returning from suspend, neither built-in keyboard nor the touchpad respond, I have to login via on-screen keyboard and then reboot for them to work - USB mouse works just fine. Recently upgraded from 18.04 where I was having the same issues.

So far I've tried the methods found here, here, here and here but none of them solved my problem.

I am a beginner Linux user, what else can I try?

  • I'm having the exact same issue, did you correct the backlight from the keyboard too? – Ruggi Jan 21 at 21:35
  • Yes. In the end, the solution was installing Mint – João Raffo Feb 6 at 18:53
  • João, actually everytime that I suspended the activity on the system the backlight started to work again, no explanation at ALL. – Ruggi Feb 7 at 19:47
  • Exactly! I found people having precisely the same issues, the solutions worked for ALL of them but for me :( – João Raffo Feb 9 at 11:05
