Plasma 6.6 will have a timeout for giving up and disabling the screen instead of using the best mode, at which point you can manually reduce the resolution or refresh rate. Ideally we'd be able to detect that and automatically downgrade the mode, but KMS still doesn't report any more information than "that doesn't work", so the timeout is the best we can do right now. -- You are receiving this mail because: You are watching all bug changes.
