DAP, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc4 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-2209 needs-upstream-testing regression- potential ** Tags added: quantal raring ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Driver won't detect monitor on DisplayPort [Radeon HD 4850] + 1002:9442 Monitor not detected via DisplayPort [Radeon HD 4850] -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1035556 Title: 1002:9442 Monitor not detected via DisplayPort [Radeon HD 4850] Status in “linux” package in Ubuntu: Incomplete Bug description: I have a PowerColor AX4850 512MD3-DHO video card, a BenQ XL2420TX monitor, and a Dell 3008WFP monitor. I tried to connect the BenQ monitor with the DisplayPort connection. This video driver did not recognize that there was anything plugged in. Even if the BenQ was the only monitor connected, the OS driver found nothing. The ATI binary BLOB did properly recognize this monitor plugged in to the DisplayPort, but that driver is unusable for other reasons. I currently have this monitor connected via HDMI, but this connection precludes the use of 120 hz refresh and 3D video.
