Define "flickering", please. I'll try to describe what I'm seeing but can try to submit a video if it isn't clear. Once plymouth starts, it looks like several refreshes per second are shifted out of the position that they're supposed to be in. Sometimes the refresh is shifted down ~ 25%, sometimes it's shifted slightly to the right and sometimes it's vertically squashed and transposed over the screen. It's almost as if the refresh rate is off. When the shifted redraws happen, I see what appear to be white and black artifacts in and around the shifted image. Do you see this if you boot with i915.i915_enable_fbc=0 ? Seems like the most likely suspect. Yes, I still see it if I boot a beta RC2 x86_64 live image using "i915.i915_enable_fbc=0" Yea this is really bad its making me feel sick. Was running lovelock with gnome 3 fine and love it, installed GTK+ development files which required upgrading some x11 files, wish i'd payed more attention. It restarted and now flicking warping fragmented screen, best discribed by Tim. So downloaded fedora 16 fresh install and its still there. Help. Oh I can stop it, this is strange. Open add/Remove software... Help->Contents. search eg "history". click "Update Viewer". And it stops with this window open. Weird. I've been testing this more with a F16 install. I can make the flickering go away or come back by varying ONLY the kernel builds (xorg and xorg-x11-drv-intel builds stay constant). Using the kernel builds that are still available through koji: - (no flickering) kernel-3.0.1-3.fc16.x86_64 - (flickering) kernel-3.1.0-0.rc3.git0.0.fc16.x86_64 I'm seeing this flickering regardless of whether or not X is running and have been doing my testing with the default target set to multi-user (runlevel 3). I have also tested kernel-3.0.1-3.fc16.x86_64 in graphical mode and there is no flickering. It looks like the kernel builds in between the two listed above are no longer available through koji but I'm planning to replicate some of them in an attempt to isolate this farther. I think that this is a duplicate of bug 753881. 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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 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. |
