I have a very annoying problem with KDE Neon 5.7. When I close the lid of my laptop, computer switches to sleep mode. When I open the lid for 10 seconds I see nothing else but black screen with cursor. How can I examine what's wrong?

Hi,

there are a couple of possible reasons for this. Most likely there is some driver or process stalling.

A good idea would be to examine the system log and look at the actions and the order of their timing.

• Close your notebook, remember the time of closing and leave it closed for like two minutes.
• Open it, remember the time
• Start a shell and run "sudo journalctl -S 12:34" (enter a time a few minutes before you closed your notebook instead of the example 12:34 to only show relevant logs)
• You can save that to file by running: sudo journalctl -S 12:34 > /tmp/some-log.txt
• Scroll up to the lines where the interrupt during sleep is visible.
• Look at the lines after the sleep gap. Note if there are major gaps in timing. If so, copy the lines immediately before and after the gap.

If you post the log here, we could have a look if maybe something is wrong there.

In case you have got some very recent hardware and that's the cause, I could tell you how to try out a more recent kernel, that resolved a couple of issues for me.

Best regards

Thanks Cymaphore. I've figured out that bluetooth is to be blamed for this. When I switched it off computer wakes in a second. Any ideas how to fix that? My laptop is not new, I bought it 3 years ago.

There are a couple of related bugreports in launchpad, like this one. It looks like there are issues with the bluez-package. No conclusive solutions within those tickets so far, as far as I could see. It looks like something within bluez needs to be fixed.

If you don't need bluetooth on a regular basis, you could disable it simply by running:

Code: Select all

sudo rfkill block bluetooth

To re-enable bluetooth, run:

Code: Select all

sudo rfkill unblock bluetooth

If you like to tinker around, you could also try if the issue is related to the driver itself by (temporary) installing the newest mainline kernel as I described in this thread and see if it resolves the problem.

Thanks for your help. I've changed kernel to 4.6.4 and now bluetooth works

Nice to hear

Just keep in mind that you have to update the kernel by yourself now, in case there are new releases.

If you like you can mark this thread as "resolved" for others to know.

Best regards,
Martin
