After upgrading 15.01 to 15.1, I started getting "Looking for control surface" hang.
Is it safe to uninstall and reinstall without loosing my old project files?

OS: Windows 10

Thanks!

Same here.
Resolve Studio 15.1 installed.

Hang at start:
looking for control surface
. . . .
Win 10 Pro

Any solutions ?!?

I got this one, too. Downgraded to 15.0.1 for now, without losing anything.

I'm also getting this too. First time it's happening to my system.

For me is the same thing and the first time I go back to 15.0.1

We can now see this.. If you have a multi-GPU Windows system, you need to set your GPU Processing Mode to Auto before upgrading to DaVinci Resolve 15.1.

This will be addressed in the next dot update.

Yes ! It's ok for me. I hope it's ok for you !
Thank you Peter

It did not work for me, unfortunately. Curious if it's just me, or if the other reporters are all good to go after setting the GPU Processing Mode to auto.

And if you don't see this recommendation and upgrade first (without GPU Processing Mode set to Auto) is there a way to recover? Would uninstall 15.1 / set GPU Processing Mode to Auto / reinstall 15.1 work?

I go back to 15.0.1. Set auto for GPU. And install 15.1 and is fine.
But don't forget to backup your database before upgrade Resolve.
But this time I haven't backup my database before and all is fine.

+1. I have this problem also. I have multiple GPUs. I un-installed 15.1 and went back to 15.0.1, changed the GPU processing mode to Auto, then upgraded to 15.1. First time it loaded, second time it got hung up again on looking for control surfaces. So apparently this is not merely a matter of changing a setting before upgrading, but changing it to "Auto" and leaving it set to "Auto" otherwise Resolve wont load. That's where Im at now. So now I have to un-install resolve, install 15.0.1 again, set the processing mode to auto and then leave it set to auto until this issue is fixed.

I have the same issue on my desktop. My notebook computer works fine. It feels like another installed program is interfering. I just wish we knew which one.

Encountered the same problem, but in my case it was reversed. The setting was originally Auto (with two GPU's on Windows 10), that worked fine. Then changed it to CUDA and then the problem started.

After several cancellations and reboots, it finally worked, also using CUDA (instead of auto).
This also seems to influence ACES 1.1, some things do not work under CUDA giving a black viewer but they do work under OpenCL.

Hi Peter !

Thanks for the workaround !
This did the trick on the multi-GPU Win 10 Pro workstation.
Now Resolve Studio 15.1 starts properly.

Having Loaders now in the Fusion Page with access to multi-layer OpenEXR file channels is a huge step !
Thanks a lot !!!

+1 on GPU Processing causing my system to freeze at the control panels search.

I reverted back to 15.0.1, changed the setting, and then upgraded. It's working for me now.

In my case, it was faster to enable SLI, which let me launch Resolve, then disable manual processing mode selection.

I though Resolve didn't support GPU SLI configuration. Is it now supported in DR15?

It doesn't, and causes weird problems. I guessed that turning it on might let me get into the settings, and I was right.

Thanks for clarifying this.

Hi all, if you have a seen this v15.1 issue where Resolve won’t complete the startup please download the updated v15.1 posted today.

Didn't help on my side (MacOS 10.12.6, only system GPU). I used the file provided this morning -> hangs on start. Reverted back to 15.0.1 and checked the settings for GPU processing mode: It was set to "Auto".

In Windows i found the workaround so you don't have to uninstall then go back to 15.0.1 to set it to auto then go back to 15.1...

Go to path: C: ProgramData/Blackmagic Design/Davinci Resolve/Preferences

open the file ".config.data" (notepad or notepad ++ ) and set GPUProcessingMode = Auto save and launch Davinci.

For mac may be the similar trick in similar path.
Didn't try on this morning version.

done, edited my post

Hi - Mac OS 10.12.6. Another one hanging on "looking for control surface" with 15.1 free version. I uninstalled my previous 15.0 beta (which was fine) and restarted before upgrading. I have checked auto setting re GPU. If I uninstall 15.1 and reinstall 15.0 it opens OK. Is there a preference or setting file that can be trashed maybe...?

MacBook Pro (Retina, 15', 2013), 2,6 GHz Intel Core i7, 16 GB 1600 MHz DDR3
Intel Iris Pro 1536 and NVIDIA GeForce GT 750M 2048 MB.

works now with version 15.1.0.025!
Oli

Thanks Oli - 15.1.0.025 opens OK on my Macboook Pro 10.12.6
