Bug Description

I am currently running a Core i3 with built in video. If I run the 2.6.31-14 from the Karmic release everything is fine. The next driver I have installed is -19. If I run that one or anything newer up to the current release (22?) I get wavy jittery video. I've tried booting of off the 9.1 workstation live CD and the 9.10 64bit server CD (which I installed from ) and everything is fine. I've also tried booting off of the 10.04 workstation and server cds and the video has the same problem.

I will try and install a couple of kernels soon so I can track down exactly which one the problem starts with. Hope fully next week.

I did some testing and it happens between Kernel 2.6.31-16 and 2.6.31-17.

Hi anothergene,

If you could also please 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.

Thanks in advance.

Tried it with 2.6.35-999-generic and the problem still exists. It's worse actually.

Ok, I did what was asked and removed the upstream testing flag. It's still marked as incomplete, what I am missing?

Would like to add a comment.

On our Samsung R530 Laptops (Our company purchased 2 a few months ago), we experience "wavy" output on the external VGA interface. The internal LCD monitor of the laptop is perfect.

Have just reported this as bug# 614238

Since buying these laptops we have not been able to use an external monitor or projector. A quick link to something telling me how to try the old karmic kernel mentioned (2.6.31-16) on either Lucid or Maverick would be helpful and I will test it.

Gene Moreau (anothergene) wrote :

Try https://wiki.ubuntu.com/KernelMainlineBuilds It's for newer kernels, but you should be able to follow the instructions to install the older ones.

Alan Lord (theopensourcerer) wrote :

I found a 2.6.31-13 Karmic kernel image in http://kernel.ubuntu.com/~kernel-ppa/mainline/ and tried that.

Unfortunately the wavyness was still present.

The whole desktop also locked-up shortly after logging in so it wasn't much of a test I'm afraid. Booted into the Maveric kernel and disabled Compiz. Then rebooted back into the 2.6.31 kernel. The desktop no longer locks up but the external display still has the wavyness.

One other point to note is that neither kernel is correctly detecting the external monitor via EDID. The maximum resolution I can set for the external monitor is 1360x768. My monitor is a native 2048x1152 Samsung 2343BW. Although the wavyness also occurs on an external 1024x768 projector too.

Any other suggestions to help track this down?

Hi, I tried kernel 2.6.36-020636rc6 from mainline and the problem steel there.

Sorry... I use Ubuntu Lucid on a intel core i3 laptop with i915 integrated graphic chip.
