(In reply to comment #0) > Now, using the proprietary driver from nvidia I was able to overcome the > monitor's deficiency to properly communicate its EDID via DVI, using the > "CustomEDID" option. You are not the first one to ask for this (bug 517962 ended with the similar request), we should do something about it. For now, I applied the second patch from that bug: https://bugs.freedesktop.org/show_bug.cgi?id=31943 (patch link: https://bugs.freedesktop.org/attachment.cgi?id=41654) to a 2.6.38.7-30.fc15.x86_64 kernel. This allows setting drm.edid_strict=0 on the kernel command line, and now the LG monitor is detected and usable. So, while the best option would still be to implement a CustomEDID option like in the binary driver, applying at least that small patch would solve the problem for some. Ping. Any news here? Would it be possible to apply the linked patch or a similar one? In fact this needs to be added to the kernel module. The patch mentioned in comment #2 applies to current F16 kernels with minimal fuzz, and works well. (In reply to comment #4) > In fact this needs to be added to the kernel module.

The same people work on both userspace and kernel, so they can deal with things as they see fit in both. This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Currently I cannot test that, but maybe the drm.edid_fixup parameter would help here. This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'.

Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
