Black/pink screen after boot, stopped by Ctrl-Alt-Backspace

[melkart]

This bug appeared when booting the Kubuntu 8.10 beta desktop ISO (i386 version). The bug did NOT appear when booting the Ubuntu 8.10 beta desktop ISO (i386).

After the startup screen, I get a screen with the upper two fifths in black, the lower three fifths in pink color. Also there appear some weird horizontal stripes in the upper part. After I press Ctrl-Alt-Backspace, I get the KDE upstart screen, then the KDE desktop. But there is still some flickering when I press the "launch" button.

My System has a nVIDIA GeForce 6100 / nForce 405 on-board graphics chip. My Monitor is a TFT with 1280x1024 max. resolution

I can conform this. Only difference with my GeForce 6150 onboard graphic is that I have a complete dark screen with white lines/strokes after booting, no colours.

Hi jfh,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

I noticed that, when I have the black/pink screen and press Alt-Crtl-F1, to get a console login, and afterwards Alt-Ctrl-F7 to get back to X, I get rid of the black/pink screen and proceed to the KDE desktop, too.

And here the /var/log/Xorg.0.log file. I didn't change the /etc/X11/xorg.conf file.

I just tried out the new Kubuntu Release Candidate. The bug is still there.

Its in the final too! Sad.

I have the same problem with a nvidia 7600GS card running Kubuntu 8.10 final
Ther isn't any problem for example with 8500GT

Hi jfh,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? 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 also attach a new /var/log/Xorg.0.log?
Thanks in advance.

I just tried the iso "kubuntu-9.04-beta-desktop-i386.iso". The bug has disappeared for me. Worked fine.

Thanks for letting us know the issue is resolved.
