** Description changed:

  I am unable to adjust the screen brightness on my Acer Aspire V5-122P.
  Adjusting brightness in the settings applet has no affect. Adjusting
- brightness with the keyboard function keys tuns the screen on and off
+ brightness with the keyboard function keys turns the screen on and off
  seemingly randomly.
- 
- I believe this (rightly or wrongly) to be a problem with the hardware
- drivers for the laptop's touch screen (rather than with xorg or the open
- source AMD graphics drivers). I have therefore filed a bug report under
- "linux".
- 
- Unfortunately I do not know how to determine the exact details of the
- touch screen. I have included the output of lspci below, but cannot see
- the screen listed. I am happy to gather further information with
- guidance.
- 
- Many thanks
