I use the Dell Vostro 3300 und Ubuntu Lucid 10.10. The VGA for the external monitor is flickering. The problem seams to be the Intel Graphics.

lspci / grep “VGA” says: VGA compatible controler: Intel Corporation Core Prozessor Integrated Graphics Controler (rev 18)

Dell told me on the telephone it is the GMA 5700MHD

Has somebody an idea, what i can do?

  • Sorry, i am an absolut beginner: if i type sudo dpkg -i linux-headers-2.6.38-997_2.6.38-997.201102120912_all.deb then I get the error message " can t find the file..." – user11038 Feb 18 '11 at 7:53
  • Running meerkat amd64 on my 3300, installed the three respective packages from here: kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/… Rebooted into new kernel but still no joy, external monitor flickering as before. Sad times – user11426 Feb 24 '11 at 21:03

First of all, you don't need to look for an Intel driver around, because it is shipped with Ubuntu and installed by default.

There is a bug with the Intel driver and the card you're mentioning (I have the same card), however most reporter have it with their laptop LCD, not the external screen. I also have no problem with external screens...

Anyway, there is a workaround for this bug that works for the LCD internal screen of the laptop, perhaps it is working also for an external LCD, you could give it a try.

Check the following bug report: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/538648

The workaround concerns adding i915.powersave=0 to the kernel parameters, see the [workaround] section in the bug description.

  • Sorry, but that is not working :( If this would be the problem the mistake would not be in 10.10. – user3257 Oct 12 '10 at 8:55
  • Are you sure you are using the GMA X4500HD ??? – user3257 Oct 12 '10 at 8:56
  • Sorry, it is the GMA x4500MHD – user3257 Oct 12 '10 at 10:09
  • I have the GM45 chipset, which according to Intel is a GMA 4500MHD so I have the mobile version, and you have the desktop version of the graphical chipset. – Huygens Oct 12 '10 at 11:14
  • Shiz, i just phoned Dell. They told me, that it is an GMA 5700MHD so, i dont know what to do :-( – user3257 Oct 12 '10 at 11:16

Patch has been found just few days ago @ https://bugs.freedesktop.org/show_bug.cgi?id=28306 But, what people like me should do? I don't know - and don't want - to recompile kernel

I prefer wait the official bugfixing

Since this machine has been certified to be used with 10.04, it is reasonable to expect this issue solved in a short time?

Install the kernel drm-intel-next available here: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/2011-02-12-natty/

It works, I have the same model of notebook and I solved with:

sudo dpkg -i linux-headers-2.6.38-997_2.6.38-997.201102120912_all.deb
sudo dpkg -i linux-headers-2.6.38-997-generic_2.6.38-997.201102120912_amd64.deb
sudo dpkg -i linux-image-2.6.38-997-generic_2.6.38-997.201102120912_amd64.deb
