I recently got a new Dell XPS 13 9365 2-in-1 laptop, I've installed Ubuntu 16.04.1 on it ( kernel 4.8.0-34-generic ) and I noticed that every time I close my laptop lid ( which sends the computer in Suspend mode ) I can not return from Suspend. If I manually go into Suspend mode ( using the GUI not by closing the lid ) I also can't return from that.
Things I've already tried:
sudo apt-get update sudo apt-get upgrade
which for what it's worth mentioned this before finishing (not sure if it's an issue or not)
W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915 W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915
Some have suggested it could be a brightness issue, which can be corrected in BIOS, but if that were the case I would assume that I would be able to ssh into my machine from another computer, and I cannot ssh into it after going into Suspend (which makes me think it's not simply a brightness issue, but is in fact stuck in Suspend mode)
I tried this script posted on Ubuntu Forums which did not work. It says it's an automated way of doing what you could do manually with Ctrl+Alt+F1 and Ctrl+Alt+F7 but those shortcut keys also do nothing for me after trying to return from Suspend (they do of course work normally, when I'm not in Suspend).
I attempted to try this fix from Ubuntu Forums which references answer #7 in this other thread. I was confused as to exactly how I should substitute the "XXXX:XX:XX.X" in the example, but seeing as how it seemed like a variation on the script I tried before (also in
/etc/pm/sleep.d/) I moved on to trying the next thing
I then tried this one Blank screen after resume - Dell M5510 Ubuntu 16.04 but this also didn't solve my problem
I also installed
laptop-mode-tools as someone suggested, but wasn't sure how to use this to address the issue.
I should also mention that I had a wireless card issue when I first installed Ubuntu, and that was fixed this way Wireless not working on Dell XPS 13 9365 Ubuntu 16.04 I mention this because it involved updating my kernel (which again is 4.8.0-34-generic) and in one post about Suspend issues they mentioned that it could be caused by the wireless card changing its status XPS 13 9343 Failure to resume from suspend
I hope this can be fixed, thanks in advance!
