Gigabyte 4090OC + CH pedals and Yoke, screen wont shut off?

[theskyisthelimit]

I'm not 100% sure this is where the issue lies, but i had a 3080ti previously and with my ch pedals and yoke the screen would time out at the time set, no issues.

I put the new 4090 in, latest nvidia driver (and previous drivers since the 4090 was released tried too), i did clean, i did DDU in safe mode etc..

No matter what, the pc screens will not timeout after the set time (nor will the pc sleep either). Pc sleep commands in terminal dont show anything holding up the system, but i know if i unplug both ch devices it works (not just 1).I dont run the geforce experience software either.

Viewing the controllers in usb controllers, im not seeing any jitter that might be causing this, again it all was working fine under the 3080ti, but maybe just a coincidence.  Im on windows 11

Has anyone ran into this and found a fix?

Well, in an interesting turn of events, i swapped out for a honeycomb yoke and moved my ch to another pc.. in BOTH cases now the pc will not sleep, 21h2 win11 on both machines. Disconnect either yoke from either system and the screen times out just fine.

I have a VKB Gladiator joystick. Took me ages to troubleshoot but when it is connected both monitor and system will not enter sleep mode. Disconnect the joystick and both devices sleep as normal. I just got used to disconnecting the joystick. Its easier with a powered USB hub that allow each port to be switched on/off.

I have not found why this happens, something to do with polling I guess.

Will watch your replies.

Cheers.

Well, i decided to do DDU again, went to safe mode, cleared things out, back to win11, tested, screen times out just fine..

Installed the latest nvidia driver.. screen STILL times out just fine.

Rebooted, now its broke again.    The issue for me popped up on switching 3080ti to 4090.. so i think its linked to the gpu driver in some way, at least post install of the driver and rebooting.
