Hello, I am using a dual monitor system (2x 1920x1080px) connected to a NVIDIA RTX4070ti with a nvidia-open-driver-G06-signed-kmp-default 580.126.18_k6.12.0_160000.26-160000.1.1.
Most of the time (but not always), my system does not resume after a screen saving and I have to use the reset button to reboot. This unhealthy situation exists since the first version of Leap 16 and was NOT solved by regularly upgrading the NVIDIA driver.
After 45 views and no answer I guess there is no easy solution…
May I ask if by “screen saving” you mean just “screen lock” as in “screen goes black for privacy while I’m occasionally not at the keyboard” or you mean “the computer goes to sleep state to preserve power”?
If the latter, there are ongoing problems since ages with Nvidia GPUs not resuming from sleep in some configurations, but screen locking should work, since the GPU is active.
On a side note, your RTX4070ti supports the 595 series driver (aka G07 driver) so you may consider upgrading to that, maybe not just right now since apparently there are some issues with the very last version, please see black-screen-on-nvidia-after-updating-to-20260428
Also, X11 is barely maintained these days, so time to at least check Wayland and if possible switch to it.
Thanks for reply, OrsoBruno. I will check for Wayland. I am also aware, that it’s not an easy problem. I guess, the solution has to come from the NVIDIA Linux team.
Sympathies as I have been around this track in the past with an older Nvidia Graphics card. Despite lots of great help from people & admins on the forum here & tinkering with lots of things like those suggested above & using Switcheroo etc. I could never get sleep to work properly with it.
The only solutions I found that worked were:
Not to allow my PC to sleep
Turn it off & back on again if I was going AFK for a longish period of time.
Eventually I took out my Nvidia Graphics card as it seemed to be playing up any way & was approaching the end of support.
My machine now sleeps perfectly again using the built in / on board / chip AMD Ryzen™ 5 5600G with Radeon™ Graphics × 12, so it seems to be an on going Nvidia issue.
This worked fine for me as I’m not a gamer & didn’t really have demanding graphics requirements. Looking at your set up it seems that your Nvidia is far superior to your built in Intel Graphics, so I’m assuming that you need your Nvidia card for your use case.
So sorry I can’t be of more help but I guess from the above options 1 & 2 maybe your only solution for now…unless someone knows how to solve this.
Try to ensure that no application using openCL is running (e.g. libreoffice-calc, Darktable, Digikam, GIMP…): does the system resume or not?
Check if anything relevant to your system is in powermanagement.html on the Nvidia README (possibly adjust the link to the version actually installed in your system).
