    Default How to troubleshoot sleep issues

    Hi all,
    I'm having difficulty reliably suspending to RAM on OpenSUSE 15.0 x64 on my Thinkpad T440p. Every 1 in 10 attempts, it sleeps properly. I have tried sleeping through KDE, systemctl suspend, and closing the lid. Suspending to disk/hibernating works fine every time.

    When I try to put the machine to sleep, the screen goes to black (backlight still on) and the mouse is the only thing showing. Then a few seconds or even minutes later the mouse disappears but the machine is still on. If I press a key at this time, then it takes a minute or two but the machine will go to the KDE lockscreen and act as if it had been sleeping (it even prompts to re-unlock GPG for WiFi passwords).

    I'm not sure how to begin troubleshooting this. Will anything show up in the systemctl journal/log? What should I look for?

    Thanks!

    Usually a graphics-related issue. Graphics hardware and driver details?
