Re: [Nix-dev] Intermittent Blank Screen upon Opening Laptop Lid

It does seem like a lot of people are experiencing this problem (on NixOS and beyond). I'll have to perform some experiments and play around with it to see how I can replicate it deterministically. On 5/07/2016 1:15 PM, Ruben Astudillo wrote: I got the same problem. I think I know the

Re: [Nix-dev] Intermittent Blank Screen upon Opening Laptop Lid

I got the same problem. I think I know the conditions that trigger the bug, it has to do with both power sources on my laptop (BAT0 ADP1) being online as per-said on /sys/class/power_supply at the same time. To avoid this I just suspend (to mem) and open the netbook without the adapter conected.

Hi Vladimir, What's the display detect button? I tried switching to text terminals whenever this happens, and while something's happening with the disk (disk indicator light), the screen's still blank. Thanks, Roger On 2/07/2016 5:54 AM, Vladimír Čunát wrote: On 07/01/2016 03:10 PM, Roger

I should be clear, that right after the logs that I posted is just `Power key pressed.` `Powering Off...` and `System is powering down.`. So the logs posted below, were 1 minute before I hard pressed the power button and forced it to shutdown. The laptop also doesn't suspend when I close the

I found something interesting on my previous boot logs, since I had to force shutdown. The error is follows (from journalctl -b -1): ``` Jul 01 23:10:48 matrix-central kernel: nvidia-modeset: WARNING: GPU:0: Lost display notification; continuing. Jul 01 23:12:32 matrix-central kernel:
