On one of my computer, sometimes, when I try to leave suspend mode, I only get a dark screen, while the keyboard and the mouse do not respond. Still, I can log to this computer using SSH and then shut it off using poweroff, but this is annoying. Here is what I get in journalctl when this problem occurs:

Well, it seems the problem is related to X.org and NVidia, which is consistent with the fact I get a dark screen and no response from keyboard and mouse. Therefore, I have tested what is suggested on NVidia website:

https://forums.developer.nvidia.com/t/solved-suspend-resuming-and-wakeup-with-nvidia370-28/45282/9

But it did not change anything, therefore I have put my configuration back to its initial state. Now, I do not have a clue on how to solve this.

Here are some information concerning my configuration:

Can anybody help me solve this?

  • Did you instal NVIDIA driver?, Installing the nvidia driver would solve this issue. Possibly this link may help you https://askubuntu.com/a/1046139/383075 – Shameerariff Oct 27 '20 at 19:47
  • Well, I do use the NVidia proprietary driver:

    $ aptitude search nvidia-driver-450 i nvidia-driver-450 - NVIDIA driver metapackage
    p nvidia-driver-450-server - NVIDIA Server Driver metapackage

  • I had the same problem, After installing the NVIDIA driver everything was resolved, except brightness control, later I modified the configuration file to get it done. The reason I shared the link was to remove the unsuccessful installed NVIDIA driver. The guide to install NVIDIA was explained in detail https://linoxide.com/linux-how-to/how-to-install-nvidia-driver-on-ubuntu/ – Shameerariff Oct 28 '20 at 04:24
  • Well, thank you, but once again, I was using NVidia proprietary driver and had no problem to install it, but I have this problem with suspend mode. I have tested with the standard kernel, but the problem persisted. Right now, I am testing Nouveau, I will see if the problem is still there. – Yoann Oct 29 '20 at 07:42

I tested with the standard kernel, but the problem persisted. So I uninstalled the proprietary driver and used Nouveau. It turned out that it fixed the problem. Furthermore, I tested some 3D visualization code that I did, I did not notice any slowdown problem and I did not see any CPU overload–these codes also do some numerical computations, so they use a lot of CPU, therefore I probably would have seen an overload if there had been some. I have also tested a video editing software and likewise it seems that the graphics card fully supports decoding. Also, I can use Wayland instead of X.org, when the proprietary driver still does not allow it. I have not been able to test computations on graphics card yet.

When my video card was new, the performance of Nouveau was lagging behind the proprietary driver. Now that the card is less recent, it seems that Nouveau performances compete with proprietary driver performances.

In any case, my observation is that NVidia slows us down in the progress of the graphics server. If you have the choice, I think it is better to prefer ATI processors. If you have a NVidia processor, if it is not too recent, it is worth trying Nouveau.

In any case, the problem is solved.
