[Bug 527149] Re: themusicalduck
Hi. Thanks for your post. I'm now experiencing that bug on a fresh installation of Lucid with the [current version] of nvidia's driver. About the video playback problem, I don't think it has anything to do with the screen flickering and freezing, although I still didn't check it on the new installation. I really hope it will get fixed. If not, I might try to reinstall Jaunty and see if it fixes the problem. -- Karmic + NVIDIA cause screen flickering, X crashes and video playback problems https://bugs.launchpad.net/bugs/527149 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 527149] Re: Karmic + NVIDIA cause screen flickering, X crashes and video playback problems
Hi Jeremy. Thanks for your email. I definitely intend to test this with new versions of Ubuntu, and I would love to assist you guys to solve this issue. I was waiting for the first official release of Lucid that's supposed to come out tomorrow (the 29th). I am now using the nv alternative video driver, and I'm pretty sure once I switch back to NVidia the bug will come back. Before upgrading to Lucid, would it be helpful it I run 'apport-collect -p linux 527149' with my current version of Karmic and post the results? Also, about upstream testing - should I do it before or after having upgraded to Lucid? And once I upgrade to Lucid, won't I already have the latest kernel version? If not - then what's the right order to do things? Thanks again, Tal On Wed, Apr 28, 2010 at 12:04 AM, Jeremy Foshee jeremy.fos...@canonical.com wrote: Hi Tal, This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 527149 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Yesterday I upgraded from Ubuntu Jaunty to Karmic, and now I'm experiencing the following problem: After logging in to the system, the screen randomly flickers, and at a certain point, one of the two things happen: 1. The X screen gets scrambled and freezes. Only the mouse can sometimes move. Sometimes I can escape this situation by pressing CTRL-ALT-1, and then returning to the regular display with CTRL-ALT-7, which causes a small temporary improvement. In other times, even pressing CTRL-ALT-1 cannot get me out of this, and the computer is completely stuck. 2. X crashes, and the GDM login screen appears. The time it takes for the session to hang varies. It can be anything between 1 minute to 30 minutes and on rare times even longer. The time duration does NOT depend on whether I'm using Compiz or not, and whether sound is being played or not. However, I think that actions which cause the window manager to work harder (e.g. opening / moving windows) can make the problem appear sooner. The second problem is that video playback fails - the video is first played correctly and after a few seconds sound stops and the playback gradually slows down until it completely stops. It happens to me in SMplayer. I'm not sure whether I tried it with other players as well. This happens in many video formats. These two problems share the following characteristics: - They started right after upgrading from Jaunty to Karmic. - They happen both when I use the NVIDIA driver from the repository (185) or the driver I downloaded from the NVIDIA site (190). - They don't happen when I use the nv video driver, or when I start Ubuntu in reduced graphics mode (by uninstalling the NVIDIA driver).

I forgot to add that I am using kernel 2.6.31-19-generic. p.s. The 2nd link I gave in the previous post is the most informative one. It's a discussion that has been going on for 4 months and spans over 16 pages with information about people's attempts to solve this bug - including different kernel versions, NVIDIA driver versions, and other changes to the system, which solved the problem for some of the people, but not for all. Generally they still could not find one magic solution that works for everyone.

Before having seen this bug report, I filed a new bug report here: https://bugs.launchpad.net/ubuntu/+bug/527149 I believe the two bugs are the same bug (except for the video playback problem, which wasn't mentioned here).

[Bug 479296] Re: Karmic: frequent freezes
I have the same bug, although I experience no difference whether music is being played or not. I suspect this has something to do with the NVIDIA driver and Karmic. I use an HP DV5 Pavilion with NVIDIA 9600M GT and Ubuntu Karmic. Prior to Karmic I used 9.04 and everything was working fine. On Karmic, the screen would randomly flicker and sometimes freeze. This happens more often whenever I perform any activity which requires more work from the window manager - e.g. moving / opening windows. When the screen freezes, either the computer is completely non-responsive, or sometimes I can use CTRL-ALT-1 to escape it, then return to the normal display and it somehow causes a small temporary improvement. Sometimes, instead of freezing, the X server completely restarts and I get to the login screen. -- Karmic: frequent freezes https://bugs.launchpad.net/bugs/479296 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
