Oneplus one: resume not working

[Johan Nilsson]

I've flashed ubuntu to my oneplus one (15.04 r15) but I can't get my phone to resume after it has been put to sleep. When I hit the power button the screen turns on for a fraction of a second and then goes black again. The only way I found to get out of this is to hold the power button to force a reboot.

Same Issue with Stable Release 15 using Multirom

I'm also using Stable Release 15 and MultiROM. Pushing the button doesn't wake up the phone . . . unless I wait for 50 seconds after pushing it, then it lights up and can be unlocked.

No idea how I stumbled on this.

I played around a little more with this problem. When the screen comes on after 50 seconds, it returns to the dimmed level -- not to the fully brightened state. This happens when the phone is set to lock screen after one minute of idleness.

If the lock screen timeout is set to 30 seconds, the dimmed display appears 20 seconds after pressing the power button. If the timeout is 2 minutes, then the phone display appears dimmed after 1:50.

In each case, the screen comes on in dimmed mode in ("Lock screen after" time - 10) seconds. Since under normal conditions the display dims about 10 seconds before locking after a period of non-use, it suggests that the phone thinks the display is active on pressing the power button, and is dimming it to alert the user that the device is about to lock itself.

Hope this provides some useful info.
