Ugly Tiles Screen when Loging in

[Sven Romeike]

After Loging in with Lightdm on my Samsung R560 with installed Ubuntu 12.04 Beta 32Bit I have a short but ugly Screen of Graphic Tiles like in old Console Video Games from the 90s if you remove the Cartridge while the Game was still running.

Its independent of Desktop Evironment and occurs in KDE as well as in Unity Login so it must either be related to lightdm, my Nvidia Driver (nvidia current-updates from the Precise repo) or both of them.

It seems like some missing or additional Graphical Buffer Swap somewhere.

and the ubuntu-bug tool is right. its a fresh install from a daily build about 1-2 weeks before the beta came out upgraded to the latest drivers andpackages and installed kubuntu-desktop from the Repo.

I still use lightdm as my Display Manager and the ugly tiles appear after hitting enter to login. I'll check if it also occurs. I can also confirm it on Xubuntu-session login

Also it doesnt matter if I hit Enter after entering my password or just click it happens all the time.

oh and unity 2d is also affected so it doesnt seem to be any composite/3D Desktop issue. posibly just a lightdm or nvidia bug. can someone confirm this on intel GPU machines?

[Sven Romeike (lun4tic)]

definately an nvidia driver issue that should be resolved when unpluging battery and PSU

Sven Romeike, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, 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 xorg REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
