[Touch-packages] [Bug 1799920] Re: External Dell P2715Q doesn't wake up from standby anymore after 18.04 -> 18.10 upgrade

2018-10-25 Thread Cedric M
Just got the external screen in the same state again (ie, blank) after
leaving the desk for 5-10 minutes.

While in that state, the external screens tells that it doesn't receive any 
signal.
Switching it's input from it's usual DP input to another one, and switching 
back again does restore the image.

  External Dell P2715Q doesn't wake up from standby anymore after 18.04
  -> 18.10 upgrade

Status in xorg package in Ubuntu:

Bug description:
  Hi,

  Since upgrading to 18.10, my Dell P2715Q external screen (connected to
  a Dell XPS 13 9343 laptop) fails to wakeup after a period of
  inactivity:

  - leave the laptop idle for a while, gnome screen lock will take over
  and shut down the internal panel & external screen (it enters power
  saving mode). Same behaviour as 18.04.

  - however, if I come back after an hour or so and move the mouse or
  press a key, only the internal panel wakes up. The external screen
  remains blank (Xorg probably think that the external screen is on as
  the password prompt of gnome screen lock will not be visible on the
  internal panel, it's probably displayed on the blank surface -- I have
  to enter my password blind to get back to the desktop).

  
  Running xrandr without any argument sometimes helps getting the external 
screen to turn on.
  When it does not, I have to turn the screen OFF and ON again.

  I haven't seen any error message in dmesg or Xorg.0.log.

[Touch-packages] [Bug 1799920] [NEW] External Dell P2715Q doesn't wake up from standby anymore after 18.04 -> 18.10 upgrade

2018-10-25 Thread Cedric M
Public bug reported:

Hi,

Since upgrading to 18.10, my Dell P2715Q external screen (connected to a
Dell XPS 13 9343 laptop) fails to wakeup after a period of inactivity:

- leave the laptop idle for a while, gnome screen lock will take over
and shut down the internal panel & external screen (it enters power
saving mode). Same behaviour as 18.04.

- however, if I come back after an hour or so and move the mouse or
press a key, only the internal panel wakes up. The external screen
remains blank (Xorg probably think that the external screen is on as the
password prompt of gnome screen lock will not be visible on the internal
panel, it's probably displayed on the blank surface -- I have to enter
my password blind to get back to the desktop).


Running xrandr without any argument sometimes helps getting the external screen 
to turn on.
When it does not, I have to turn the screen OFF and ON again.

I haven't seen any error message in dmesg or Xorg.0.log.
