I'm using Ubuntu for the first time on my laptop, and everything is fine except that whenever I suspend the system (either manually or by closing the lid) and then resume, I get a completely black screen which forces me to do a hard reset. I tried running pm-suspend --quirk-s3-mode
, but when I resumed from that it displayed the screen I had before pressing enter, only it was completely frozen and no key-combos would break it. I've tried searching for solutions, but they've all been for previous versions of Ubuntu. Here are my specs (don't know what's relevant, will add what's necessary):
- Laptop: Lenovo Z50-70
- Kernel: Linux 3.19.0-28-generic
- Display: GF117M with nouveau driver
EDIT: I just tried sudo pm-suspend --quirk-vbemode-restore
with the same results as s3-mode. I got an error report on reboot which I submitted, but I don't know where to pull that up so that I can copy it.
Things I've tried:
- Locking screen, closing lid, then opening and resuming (black screen)
- Running
pm-suspend
in virtual console (resumes to virtual console, but frozen) - Switching to a proprietary driver and trying the above again (same problems)
EDIT2: Working through the top answer here (though GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"
hasn't worked) and then trying this
EDIT3: Error message
