nvidia processes

Usually when I install new nvidia drivers, I get a message from DF asking if I want to disable nvidia processes that interfere with DF, and I do so. That didn't happen on my last install of drivers, and I THINK it's because I installed DCH drivers this time, rather than standard drivers. I was able to solve the issue on my own by renaming both nvsmartmaxapp.exe and nvsmartmaxapp64.exe in C:\Windows\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_b9ae772eb7ef9895 (had to change permissions on the directory first).

Is this a compatibility limitation with DCH drivers right now, or is there another issue going on here?

It could be, yeah. We've never tested with anything but the official NVIDIA drivers. Could you send me the link to where you downloaded them?

DCH drivers /are/ official nvidia drivers. They're made to follow the new standards for drivers laid out by microsoft for Windows 10. They can be downloaded from the same Nvidia site for standard drivers, but you have to select DCH drivers rather than standard drivers in the search. The installation will also fail if the standard drivers aren't completely wiped from the system beforehand, and vice versa for standard drivers (DDU suggested).

Ah, interesting! Thanks for the extra info, I hadn't seen that DCH option before. We'll do some further testing here and see what we can find out.

Thanks!

Just a quick heads up, I was able to reproduce this here and have added it to our list to fix up.

Thanks!

Any luck yet? It looks like Nvidia is fully moving over to DCH drivers as of 2019-12-06. Their latest drivers are now DCH by default and can be installed over their standard drivers without wiping first (meaning anyone updating their drivers will most likely get DCH now unless they specifically look for non-DCH drivers as mentioned next). Standard drivers can now only be downloaded via advanced search.

Getting there! We should have this fixed up for 9.6 Beta 8 with any luck

Great!

Here's a link to the new Nvidia FAQ page on DCH drivers that came up last week for anyone reading this who's interested: https://nvidia.custhelp.com/app/answers/detail/a_id/4777/~/nvidia-dch%2Fstandard-display-drivers-for-windows-10-faq

Also worth noting for anyone reading this, if your taskbar is stuck up (with auto hide on) after updating Nvidia drivers, that's due to nvsmartmaxapp(64).exe conflicting with DF (assuming you're using DF taskbars). Just rename/delete the two files directly for now. You should see them running in task manager and can right click on them there to find their directory. As stated in my first comment, you'll have to take ownership of the directory and change permissions to be able to do so.

I'm on 9.6.2 beta 1 at the moment and I just updated to the latest nvidia drivers. I'm not seeing any sort of UI for disabling the nvidia processes again.

Sorry, I forgot about this. I'm on 9.7 Beta 5 now and it's still happening with the latest nvidia drivers (downloaded and installed today). Whatever changes were made in 9.6 Beta 8 appear to be completely gone (from a gui/functionality pov anyway).

Here's the export you asked for. I've checked all my settings pretty thoroughly and can't find any issues there as far as I can tell. For now I've just been doing the permissions edit and renaming I mentioned above. I never get prompted by DF to disable nvidia processes after a driver update.

Thank you for the information! We're a bit backed-up right now but we'll take a look as soon as we can and get back to you. Thanks!

Just a quick update to let you know that we've found the issue here and it will be fixed up in the next beta. We'll follow-up when it's available to try out.

Thanks!

We've just released a new DisplayFusion Beta version and this issue should be all fixed up. Please let us know if you run into any trouble after updating.

Thanks!

I just updated my nvidia drivers (to undo my manual renaming) and displayfusion, and rebooted my system. I'm still not seeing any dialog from displayfusion to disable any nvidia processes. I can see from task manager that the processes are still running as well.

Additionally, another tool I use (Peach, available on the microsoft store) is now crashing on launch. Killing DF instantly allows it to run correctly. It was not exhibiting this behavior before this DF update. I'm seeing the following 4 entries in event viewer on every crash:

EDIT: At this time, I'd like to roll back to beta 6, but I can't find a direct link to it anywhere. Please provide one if possible, thanks!

We're posting 9.7 Beta 8 shortly to fix that crashing issue. After updating to Beta 8, could you send me a new copy of your DisplayFusion troubleshooting info?

I can't figure out what's different here. When we test with the DCH drivers, it prompts correctly and disables them

Could you tell me what folder the nvsmartmaxapp processes are in on your machine?

Both are located in C:\Windows\System32\DriverStore\FileRepository\nvbli.inf_amd64_2d4a5fbb20e2c58d\

I have yet to see a single prompt on recent versions, but back when you first released an update that included this in the change log (before I mentioned that it's broken again in the recent betas), I recall having been prompted once correctly. Though it was a while ago so I could be making things up in my head.

Hi,

Would you be able to get a new debug log with the newest DisplayFusion beta? We'd love to get to the bottom of this! Here's how to get that to us:

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • Reproduce the issue and note the time so we'll know where to check in the log file
  • Click the "Export Info to File" button on the Settings > Troubleshooting tab
  • Reply with the file attached
  • Disable debug logging after sending the log

Thanks!

To clarify, what exactly am I reproducing? From my understanding, this is a check which should always happen (at least that's how I remember the behavior from the days before DCH drivers).

Thanks! Would you be able to update to 9.7 Beta 9, then send us a new L1 debug log?

  • On the DisplayFusion Settings > Troubleshooting tab, change the Logging drop-down to "L1: Log Minimal" and click Apply
  • Restart DisplayFusion and make sure that the Monitor Splits are enabled
  • Wait a minute to give the polling a chance to try and detect the NVIDIA helper processes
  • Click the "Export Info to File" button on the Settings > Troubleshooting tab
  • Reply with the file attached
  • Disable debug logging after sending the log

Thanks!

Sorry things got busy around here and I didn't get to this. I do have some more data though. I just built a brand new system, which I of course promptly installed the latest DF on (beta 10). Upon launching, it instantly detected that nvidia processes were running (latest drivers) and asked if they should be disabled. I selected the option to disable them, but nothing happened, the processes remained running, and I had to manually disable them using the method I mentioned before. Could it be a permissions issue?

We did find an issue in a code review with this, so this should hopefully be working in Beta 11. We'll let you know as soon as it's available to try out

Thanks!

Happy to report that upon reinstalling my drivers, DF immediately detected the processes on the next boot and was able to properly disable them this time. Checked the directory to be certain and sure enough, they were renamed. Thanks for getting this working!
