Some Fn keys only work intermittently on Toshiba Tecra laptop with Deepin 15.5


I am relatively new to Linux and Deepin. Been using Deepin now for roughly 8 months.

On my Toshiba Tecra laptop the Fn keys - Volume (up/down/mute), Player (play/pause/next/previous) and the Brightness keys work once in a while. For instance the volume keys work only directly after login.

Is there a solution for this? I have looked on the internet, but found solutions for Ubuntu and KDE. I am hesitant to apply these changes to Deepin.

If anyone can help, it would be greatly appreciated!

Thank you in advance

Clean the keyboard with a can of compressed air or buy replacement is all I can suggest. They do go bad when cookies, cat fur, etc.... and coffee get spilled/scattered on em. Key contacts do wear out.

I only mention this because I have fixed left mouse click which was a physical problem on a Asus EEEPC 900.
It required me to take the mouse pad apart.

All is mentioned above because of the statement

work once in a while

Try this in Deepin for my curiosity. Post results in your next post. Open a terminal and type in. Then copy and paste in code tags < between the code][/code > the readout in go advanced reply toolbar. It is the hashtag symbol on the tool bar.

Deepin is based on Ubuntu as far as I know. KDE is universal. I'd just make sure your found fix suggestions match the version of Ubuntu and KDE that you are using. I don't think this is software breakage though. But hardware breakage instead.

Edit: Forgot my manners. Howdy and Welcome to LQ.

@rokytnji - Thank you for the reply mate.

The keyboard: I use bluetooth keyboards and laptop keys and the Fn keys does not work with either. I forgot to mention that they keys do work on the Windows installation that I have as as a dual boot (for work).

The keys were working on Deepin 15.4. Incidently Deepin is based on Debian currently.

I'm not sure what else you've tried, but I found these here that might have some things you could potentially try:

It's not exactly Deepin, but I'm hoping it will push you in the right direction.
