Suspension on my laptop (closing the lid) causes Wifi to not be available.
Hi, this is a long lasting problem that I didn't really manage to fix when I started using linux (Mint, Cinnamon). But now that I've been using it regularly for half a year and I have more experience in fiddling around, I'm trying to get it resolved.
Whenever I suspend the laptop (or close the lid, which does it automatically) the Wifi and sometimes an external monitor don't work anymore, I don't know what the problem is. The wifi is fixed by powering on and off again. To fix the monitor sometimes even powering off and on again didn't fix it, I usually waited for the next day and it worked again.
I've no idea of how to fix this (Linux Mint forums didn't help at the time)
Laptop is an MSI GS65-Stealth-Thin-8RF running Linux Mint, with Cinnamon Desktop
Any additional details you can add would go a long way towards troubleshooting. That desktop are you using (ex: Gnome, KDE, etc) and what model of laptop, the full hardware specs including CPU, GPU, WiFi model, etc. Finally, you'll want to look at the system logs to see if there's anything useful in there after resuming from sleep (journalctl).
I must have just missed that originally, I was commenting before coffee.
I see you have the combination graphics (Optimus is what it was originally called IIRC) which has a history of sleep wake issues, that might be a good place to start on the monitor search.
I'm trying to get the logs, but it's difficoult to paste them all here, I got a few on this link. But they all seem from 20 October, wierd. https://sharetext.me/nqz5mfph2y
The lines are quite many, they started at 1pm, while now that I was testing it's 5pm, only to go down by one minute it took quite a long time (definetly more than 1 minute) I'm not sure how to check
