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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/712075 Title: [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/712075/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
