435.17/2080Ti: 20 second driver delay in X-Server start due to DisplayPort detection

Graphics / Linux Linux

With 435.17, I see a long delay in X Server startup due to DisplayPort detection. Previous versions all worked fine.
2080Ti with an LG Ultrawide display attached to one of the DisplayPort outputs.

EDIT: there’s also a 10-second delay on X-Server shutdown.

I have run into the same problem. Also, for what it’s worth, with an LG monitor and 2080 Ti. I tried forcing ‘ConnectedMonitor’ but it still does the device detection.

Same here. Desktop (1080) and laptop (2070).

Thanks for reporting this. I reproduced the problem and the good news is that it’s already fixed in the release branch and the fix should be available in the next build.
