Kde plasma lock screen freeze issue

General system Newbie

I’m curious how you might have come to that conclusion? Nvidia has recommended nvidia-open for:

For newer GPUs from the Turing, Ampere, Ada Lovelace, or Hopper architectures, NVIDIA recommends switching to the open-source GPU kernel modules.

Your GPU is a Turing:

To clarify, nvidia-open is Nvidia’s own driver, it is not to be confused with the community developed open source nouveau driver.

@Bink

Official Source #1 – NVIDIA README (from their 545 driver):

“The open kernel modules cannot support GPUs before Turing, because the open kernel modules depend on the GPU System Processor (GSP) first introduced in Turing.” (download.nvidia.com)

Official Source #2 – NVIDIA GitHub issue:

“Unfortunately, the open kernel modules here rely on the GSP (GPU System Processor), which was first introduced in Turing. That is why the open kernel modules can’t support pre‑Turing GPUs.” (github.com)

Since the GTX 1650 Mobile (TU117M) is a Turing-based GPU but lacks GSP, it’s not fully supported by nvidia-open, I guess that the proprietary nvidia driver remains the correct choice.

Thank you @gautam256, I appreciate you clarifying that. It’s something I’ll need to keep in mind when offering help to others with mobile Turing’s. Come to think of it, I suspect a laptop I manage might even be using one, so good to know.

that’s great to here @Bink .

@manuel the issue still persists. Can you please help me with this

not sure how to proceed as it is causing lot of difficulty while rebooting it again and again.

Looked at your kernel parameters:

nvidia_drm.modeset=1 loglevel=3 nvidia.NVreg_PreserveVideoMemoryAllocations=1 nvidia.NVreg_TemporaryFilePath=/var/tmp

I think some (if not all) of them is not needed since Arch should include them already.
So worth trying to remove them, maybe one by one.

One additional thing to check: is your system fully updated? Especially kernel version needs to be compatible with nvidia version, usually they are updated at the same time. Or you could use the dkms version of the Nvidia driver (and make sure you have kernel headers installed too).

Are you using the Nvidia or Intel GPU? If Nvidia, then I’d try blacklisting i915 (the Intel driver). That might reveal if one driver is conflicting with the other.

The Arch wiki has lots of info about Nvidia GPUs, check it if you haven’t already.

BTW, if you must reboot “the hard way” after a freeze, please consider using REISUB. You’ll find info about it on this forum, or more easily, in the Tips tab of the Welcome app (run eos-welcome -1 if you have disabled it).
