[Powerdevil] [Bug 496850] Display gives black screen (no signal) after monitor powered off then on again
https://bugs.kde.org/show_bug.cgi?id=496850 --- Comment #3 from Rock Bollinger --- This issue seems to be fixed in Fedora 41, with nVidia driver 565.57.01. Sleep/Resume now functions correctly, and it's fast!

https://bugs.kde.org/show_bug.cgi?id=496850 --- Comment #2 from Rock Bollinger --- Thanks John. I've confirmed it's an nVidia driver issue. Switching to the nouveau driver fixes the problem - sleeping and resuming from sleep function correctly, the display comes back on as expected. Hopefully nVidia fix this soon. The nouveau driver is limited to 60Hz, doesn't have HDR and generally just doesn't look as clear. -- You are receiving this mail because: You are watching all bug changes.

Unfortunately this appears to be an upstream Nvidia driver issue. Please see bullet point 4 of the "Known Issues And Workarounds" section linked here: https://download.nvidia.com/XFree86/Linux-x86_64/565.77/README/dynamicpowermanagement.html#KnownIssuesAndW6426e (This particular link is to the most recent version, but the same content has appeared since at least version 545) The individual who identified the documentation from Nvidia about this issue also mentioned that on their system, it couldn't be reproduced on Wayland, so that may be a workaround option for you as well: https://bugs.kde.org/show_bug.cgi?id=466705#c2 The Nvidia forum might possibly provide some more assistance - a link to a recent post on this topic is here: https://forums.developer.nvidia.com/t/black-screen-after-pc-wakes-up-from-suspend/304023 Thanks, *** This bug has been marked as a duplicate of bug 466705 *** -- You are receiving this mail because: You are watching all bug changes.
