I don't think that's the issue. The nvidia problem I was used to is being unable to resume. I also tested with the nvidia drivers disabled and this issue still persists. Something I noticed is that I was not on the recommended version of nvidia drivers which is 415 and I just changed that now upgrading to 418. Still exactly the same issue.
Tested with various DE's and even out DE's running. Do you have any other guess? Is there a better way to find out what's wrong? To see dmesg while it is trying to hibernate maybe? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1819915 Title: s2disk freezes at saving image to disk (hibernation) Status in linux package in Ubuntu: Confirmed Bug description: This started happening after I upgrade to ubuntu 18.04.2. In 18.04.1 hibernation was working flawlessly on my machine. (with kernel 4.15-46! not a kernel issue then?) Another thing that got updated recently was nvidia drivers which were known to cause hibernation issues, but those were on restoring the snapshot. http://imgur.com/gallery/jOyHEcL --> I get stuck on this screen after running hibernate or pm-hibernate. (sys-req REISUB combination works there and is the only good way to restart I found) SPECS Laptop Dell Inspiron 7567 A30P Intel Core i7-7700HQ 1x 16 GB DDR4 1 TB HDD + 256 GB SSD Nvidia GeForce GTX 1050 Ti FHD display Intel Dual Band Wireless AC 3165 1x1 Motherboard: Intel HM175 Graphics adapter: NVIDIA GeForce GTX 1050 Ti (Laptop) - 4096 MB, Core: 1620 MHz, Memory: 1752 MHz, GDDR5, 22.214.171.12420 (ForceWare 373.20), Nvidia Optimus nvidia driver: 415.27 INFO # uname -a Linux matheus-Inspiron-15-7000-Gaming 4.15.0-46-generic #49-Ubuntu SMP Wed Feb 6 09:33:07 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux # free -m total used free shared buff/cache available Mem: 15906 2925 8742 161 4238 12485 Swap: 16333 0 16333 # cat /etc/fstab | grep swap # swap was on /dev/sda8 during installation UUID=70d967e6-ad52-4c21-baf0-01a813ccc6ac none swap sw 0 0 n root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep hibernate root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep hiber root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep s2disk root@matheus-Inspiron-15-7000-Gaming:/home/matheus# cat /var/log/syslog | grep hibernation I could find nothing scrolling up on syslog about the hibernation process or with grep.... An interesting Note is that if I run hibernate just after I boot, it works and resumes perfectly! But after some system usage it randomly has that problem if I try. The percentage it freezes at is also random, sometimes 0, 1 even 30 once. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC0D0c: matheus 25949 F...m pulseaudio /dev/snd/pcmC0D0p: matheus 25949 F...m pulseaudio /dev/snd/controlC0: matheus 25949 F.... pulseaudio /dev/snd/seq: matheus 4986 f.... qsynth CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=bfc6f294-b737-4999-a444-01e1f410de06 InstallationDate: Installed on 2018-05-10 (308 days ago) InstallationMedia: Kubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) MachineType: Dell Inc.
