I just installed a new 1 TB Samsung 870 EVO SSD in a Thinkpad X120e laptop and installed openSUSE Leap 15.2 on it.
I wonder whether anyone has any experience with openSUSE 15.2 on the Samsung 870 EVO SSD concerning hibernating. After installation and a couple of clean reboots, I clicked on “Sleep” in the display manager (SSDM). The screen went blank and the power button kept blinking for a few minutes. I had to press the power button for more than 10 seconds to reboot and even then the laptop would not start properly and I had to press the power button again for 10 seconds after which it finally booted properly. I normally don’t use “Sleep” (suspend to RAM) anyway, but I do often use “Hibernate” (suspend to disk), but because of my bad experience with “Sleep” I am nervous trying out hibernating. My questions are:
Does anybody have experience hibernating with Samsung 870 EVO SSD and openSUSE 15.2?
Is there any way that I can perform a “safe” hibernate, i.e., turn off features that may cause problems?
What is the best way to troubleshoot sleep/hibernate problems, i.e., where do I find log files and what configuration files can I tweak?
I normally use TDE as my desktop environment although I have not tried hibernating from TDE. My attempt to use “Sleep” was from the SSDM (KDE/plasma default) display manager.
Any help would be greatly appreciated.
