Till Kamppeter, I noticed you omitted following the kernel.org format, on the grounds of you having identified the regression commit, and others noted they are experiencing a similar issue. The kernel.org format as outlined by Linus was created to be in addition to regression commit identification and duplicate notices, not in substitution. This omission would more than likely be a reason why your e-mail was promptly ignored. ;) If you wouldn't mind, after testing the lastest mainline kernel via http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.12-rc2-saucy/ , and assuming it's still reproducible, having another go at the mailing list following the format verbatim would probably yield you an upstream response in a timely manner. ** Tags added: needs-upstream-testing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1167301 Title: 8086:0166 [ThinkPad Twist S230u 3347] REGRESSION: Mirroring display works only with 1024x768 (4:3) whereas my laptop has 1366x768 (16:9) external monitor 1920x1080 (16:9) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1167301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Till, thanks for the URL. Unfortunately, attachments are silently discarded before being posted to the archive so only the direct subscriber would get the kernel.org format information, versus wider audience. Not all of upstream would be directly subscribed, some just check the mailing list when someone pings them or whenever they feel like (I personally do the latter as I don't like getting 1000s of e-mails in my inbox daily). Also, it notes how: This is a kernel regression from 3.8.0-7-generic to 3.8.0-19. Some in upstream are not receptive to distro/downstream kernel mentioning, will stop reading at that point, and move on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1167301 Title: 8086:0166 [ThinkPad Twist S230u 3347] REGRESSION: Mirroring display works only with 1024x768 (4:3) whereas my laptop has 1366x768 (16:9) external monitor 1920x1080 (16:9) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1167301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Till Kamppeter, while reverting GIT commit 740922e downstream is technically possible, it would be best to engage upstream for a wider audience input on reversion or fix. Would you have the URL of the maintainer mailing list archive when you e-mailed them, that was CC'ed to the regression author: Author: Paulo Zanoni paulo.r.zan...@intel.com ** Description changed: I have a Lenovo Thinkpad Twist with an internal 1366x768 (16:9) display and I have connected and external 1920x1080 (16:9) monitor via HDMI. By default the display gets mirrored with only 1024x768 (4:3) because this is the highest common resolution of the two reported by xrandr. I can switch to a large desktop formed by the two screens with the System Settings (section Display) with each screen using its native resolution.

The problem also persists when connecting the external screen to the Mini DisplayPort (with adapter) instead of to the HDMI.

Thanks for identifying the culprit, Til. Since the problem still exists from 3.8.8 all the way through to current mainline (3.11), I think the best course of action is for you to file a bug against DRM on bugzilla.kernel.org, so that upstream can sort out how they want to address it.

The final result of my bisect is actually what I guessed in the previous comment (see output below). The patch (also below) is simple and one can easily see that undoing it would solve the problem. It seems that some monitors (including my monitor) report that they are non-continuous frequency but in reality they are. The simplest way to fix this bug is simply to undo the patch to support such buggy monitors, the correct fix would be an exception list with the monitors which support resolutions which they do not report. There should perhaps be a possibility to override this manually by a run-time configuration bit so that for all monitors the non-reported resolutions get listed. till@till-twist:~/kernel/linux-stable$ git bisect good 740922ee575f8ee4daa2bfd3db5f69dd7573fc76 is the first bad commit commit 740922ee575f8ee4daa2bfd3db5f69dd7573fc76 Author: Paulo Zanoni paulo.r.zan...@intel.com Date: Fri Feb 15 13:36:27 2013 -0200 drm: don't add inferred modes for monitors that don't support them commit 196e077dc165a307efbd9e7569f81bbdbcf18f65 upstream.

Yes, I have found out already that in the mainline I have to check 3.8 as newest good and 3.8.1 as oldest bad kernel release. Currently I am doing a doing a GIT bisect between these two. According to the estimates by git bisect I am currently building for the third-last stage, finishing in 20 minutes from now (18:00 CEST), after that I have to do more two steps of 40 minutes build time each, arriving at the result at ~19:30 CEST.

Hi Till, I can assist with the bisect. 3.8.0-9.18 was rebased to upstream v3.8.1, so the bug may have come in with the stable update. Can you test the following two kernels: v3.8 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-raring/ v3.8.1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.1-raring/ I assume 3.8 will be find and 3.8.1 will have the bug. If so, I'll start a bisect between these two versions and build you a test kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1167301 Title: 8086:0166 [ThinkPad Twist S230u 3347] REGRESSION: Mirroring display works only with 1024x768 (4:3) whereas my laptop has 1366x768 (16:9) external monitor 1920x1080 (16:9) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1167301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for all the info, Till. Can you also test the latest 3.11 kernel to confirm the bug happens there as well? If it does, we should send you patch upstream for inclusion in Mainline and cc stable to have it propagated to the stable trees.

Till Kamppeter, the next step would be to bisect the kernel from 3.8.0-7 to 3.8.0-19 in order to identify the offending regression commit.

The last good kernel was 3.8.0-8.17 and the first bad kernel was 3.8.0-9.18. The changelog between the two releases is rather small but I do not really have an idea which change could be the culprit. See https://launchpad.net/ubuntu/+source/linux/3.8.0-9.18 I tried to bisect commits with git, but the two tags Ubuntu-3.8.0-9.18 and Ubuntu-3.8.0-8.17 are non-linear, so git bisect does not find the path between them. Perhaps the debdiff or the changes described by the changelog items need to get investigated. ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1167301 Title: 8086:0166 [ThinkPad Twist S230u 3347] REGRESSION: Mirroring display works only with 1024x768 (4:3) whereas my laptop has 1366x768 (16:9) external monitor 1920x1080 (16:9) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1167301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Till Kamppeter, 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 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 Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
