Nouveau log (dmesg)
While trying to use Nouveau driver with display that sends incorrect EDID (only
FF, Samsung 226BW), screen flickers every ~10 seconds. Attached nouveau driver
log.
Everything works fine and very smooth, I can pass custom modelines to X server
to have 1680x1050 resolution, the only thing left that works very bad is this
flicker. If this matters, my GPU is GeForce 8600 GT.
Windows 7 uses 1024x768 resolution (same as Nouveau) while installing, but
without flicker.
Everytime log is filled up with new message, flicker happens.

You can use the following work-around 1. mkdir [KERNEL-FIRMWARE-DIRECTORY]/edid 2. cp [MONITOR-EDID-FILE].bin [KERNEL-FIRMWARE-DIRECTORY]/edid 3. add the following to your Kernel Commandline: drm_kms_helper.edid_firmware=edid/[MONITOR-EDID-FILE].bin This will provide kms and Friends with correct EDID-Informations. However to stop the annoying flicker, you have to 4. add another Statement to your Kernel Commandline: drm_kms_helper.poll=0 -- You are receiving this mail because: You are the assignee for the bug.

The flickering happens when someone runs xrandr. This is a hardware issue as the problem happens even with when using the proprietary driver. This issue got fixed starting with the geforce 8. The desktop environment shouldn't poll on xrandr like that, so there is a bug on their side. On our side, the workaround suggested by Jan will be our "solution" until someone really wants to dig into this issue and see if there is a way to build a cache or something to avoid load detection. In any case, I'm tempted to close this bug as "WONTFIX" but I'll wait for other devs to agree before doing so. -- You are receiving this mail because: You are the assignee for the bug.

Currently nouveau uses the former method which contributes (not sure to what extend) to the flicker. -- You are receiving this mail because: You are the assignee for the bug.
