Description of problem: From time to time X fails to initialize with rhgb turned on. I've seen this issue on various intel based notebooks (i945GM, core i5-540M (arrendale), core-i7 (sandy bridge)) and reported it to the intel driver developers: https://bugs.freedesktop.org/show_bug.cgi?id=42972 They analyzed the issue (this included generating a very detailed Xorg debug trace), and according to their analysis its a system configuration issue - because something else is still drm master when starting X, causing the intel driver to bail out. Version-Release number of selected component (if applicable): Fedora 17 plymouth-0.8.5-0.2012.04.27.2.fc17.x86_64 How reproducible: Sometimes Steps to Reproduce: 1. Boot the notebook with rhgb turned on 2. Sometimes X fails to initialize (~5%); doesn't make a difference if I am working with the notebook panel or an external monitor Actual results: X fails to initialize, because some other program is still DRM master Expected results: The program still beeing drm master when X is started should stop claiming drm master ownership. Additional info:
forgot to mention, I have never experienced this problem when rhgb was turned off (usually did this after running into the problem a few times)
we definitely supposed to be dropping master before X is starting (code is written to do that). Can you add plymouth.debug to the kernel command line and then attach /var/log/plymouth-debug.log for a run when this problem happens? Before doing that, can you try the latest plymouth from updates-testing (make sure you dracut -f after installing it to rebuild your initrd) just so we're working from the latest codebase.
Haven't seen this for quite some time, probably it has been fixed in the meanwhile. Thanks =)
Ok, happens more frequently again with Fedora17 + current stable updates, probably it regressed again. Please find a plymouth-debug log attached, which was created when I reproduced the issue again.

This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '17'. 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 17'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 17 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 to Fedora 17's end of life. 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 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 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. Thank you for reporting this bug and we are sorry it could not be fixed.
If anyone still cares, Is that bug still present on current fedora ? If yes is it reported ? I would say yes but I havent tested much Anyway let me notify that ubuntu workaround this race issues with a "try loop" patch ... https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/982889#149 Regards
