Thanks for posting a way to fix the issue manually. Unfortunately, currently we do not have an infrastructure for dynamically replacing the EDID, so since this is a replacement edid file rather than an actual patch, I'm unmarking it as a solution to the bug.
However, I think this is a good example of the type of issue discussed for addressing as part of the "hardware-desktop-n-xorg-configuration- the-final-ten-percent" specification, so I've linked it from there. Basically, we need a user-friendly mechanism for editing/overriding EDID's where the monitor is supplying a bad EDID. In some cases we can quirk around it in the kernel driver, but obviously with nvidia being closed source that's not possible. But this bug report demonstrates that given a proper replacement EDID file, it can be overridden for -nvidia in xorg.conf. So perhaps this functionality could be incorporated into nvidia-config, xdiagnose, or some other utility as appropriate. The question then becomes, how to generate the replacement EDID. In the original forum post referenced here, the contributor used a Windows utility called Phoenix(?) to generate it. I don't think we have an equivalent tool on linux, although we do have tools to decode EDID in the form of read-edid and edid-decode (which I've just uploaded to universe today). Presumably it would be feasible to create an edid encoding tool by essentially inverting the decoder logic. -- Dell Inspiron 8200 Nvidia proprietary driver causes display errors (vertical lines on the right, and mirror effect on the bottom)[Workaround Available] https://bugs.launchpad.net/bugs/33075 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
