[SOLVED]Problems with "suspend to RAM" in Debian 10.2

0good0 · 11-21-2019, 10:56 AM

I have asked this question in Debian user forums, but without success.
I am having problems with suspend to ram function in debian 10.2 (previously in debian 9.x). When I select the "suspend to ram" from start menu, system goes to suspended mode, but wake up is the problem. The system freezes and screen is black. I have to do hardware reset to my machine. In windows, suspend to ram is working, so my hardware is not the problem.
I have "Gigabyte P61-DS3-B3" motherboard, and "Gigabyte Nvidia GeForce 210" graphics card. I think that the problem is with the driver of the graphics card. I am using KDE and Nouveau driver.

I looked at this yesterday and then looked away, as I've not encountered something like this. I did, however, have an idea for testing.

Boot to a Live CD of some distro other than a Debian based one that has a suspend capability. Try suspending the Live CD, waiting a reasonable time, then coming out of suspend. If suspend works in the Live CD, then the issue is definitely with Debian.

You might also look in the log files, but that's a long shot. Whatever is interfering with the suspend is likely also preventing anything to be logged, but it's worth a shot.

How do you wake up the system?

I have downloaded Fedora 31 KDE Plasma Desktop and booted from usb. Everything is working fine. Definitely, the issue is with Debian.

There is no error log entries from kernel. Also there is no error entries or warnings for my user account. The log is very long maybe you could suggest what to look for.

The first thing I always do in this kind of situation is hit caps lock and see if the light comes on. If it doesn't, your system really has crashed. If it does, the system is running; you just have no video.

I have solved the problem. Missing firmware file was the problem. I have installed firmware-linux and firmware-misc-nonfree packages and now everything is working fine.
Thanks to all contributors.
