Ubuntu – GMA 5700 MHD Dell Vostro 3300 externel vga monitor is flickering

10.10dellintel graphics

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?

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.
