[SOLVED] Fail to resume after suspend using lid and other issues

[stevef]

Thanks for the more detailed explanation - having the context is so useful.

To summarise, the symptom is that a suspend of 30 minutes or longer initiated by any means always fails to resume as expected but returns a black screen.
Console access (Ctrl Alt F2) is possible from the black screen.

You mention being on battery only during the test.  Provided the RAM has power for the duration, the length of time spent in suspend should not make a difference.
If your RAM had lost power while suspended, I doubt the resume operation would be as 'good' as it is, but who knows.
Please can you confirm that you get the same problem with external power supplied throughout the suspend/resume cycle.

I will try similar on my system and report back.  If I can reproduce the time related problem with resuming the desktop it will be easier to work on.

As an aside, when you get the the terminal screen after the blank screen, forcing a power off may be detrimental.

Running this command

Code:

poweroff

should initiate an ordered shutdown.

Regarding the attachments. It seems the box appears after trying a preview of the post (which I do normally) - I'm still getting used to the new forum and hadn't noticed it wasn't there unless the preview had been done.  Very odd.
