Comment 54 for bug 712075

I have Samsung Syncmaster 204Ts which worked fine with Ubuntu 10.04 using DVI connection. Since 10.10 the screen is blank with DVI connection and I get invalid EDID errors constantly.

Combining two solutions below I was able to get DVI working again:

#1: http://lists.freedesktop.org/archives/dri-devel/2011-January/006778.html (kernel patch + adding to kernel command line: "drm.edid_strict=0"). This change never got into official kernel (see the thread above).

#2: Disabling polling (message #43) with: echo 0 > /sys/module/drm_kms_helper/parameters/poll

With #1 I got DVI to work again, but I still got EDID errors every 10 s in log files. With #2 those EDID errors diapperead too.

I have to keep patching (if using this monitor) until this is solved somehow in the kernel.
