Ubuntu 10.04, Intel driver and screen flickering problem

I've installed the Ubuntu 10.04 on my fujitsu notebook for a month. I found that it sometimes flickering (whole screen in white and then back to normal) the whole screen. Does anyone have the s ame problem?

My notebook is Fujitsu S6430 with Intel Graphic 4500.

I have the same issue with a Fujitsu Siemens Li3710, and Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller. Any help would be appreciated :)

I have a similar problem on my hp dv6. an intermittent screen flicker.

I have FS aswell.

And Ubuntu 10.04 sine 29 april Today found that add this to grub command line

i915.modeset=1 gfxpayload=1024x768

help much to avoid flickerig screen before load gnome.

PS.But installed intel ppa drivers and can get only vesa drivres insted intel. :lolflag: Overall preformacne is worse Now tray downgrade or switch to intel drivers

I am still having problems, despite all of the solutions offered (GRUB menu, xorg updates, etc). This is going to be a killer for me for Ubuntu - I cannot work on a computer with flickering at random times. It gives me a headache, and I can't give presentations. Hopefully someone figures this out soon.

I think my graphics card is either 00:02.0 or 00:02.1, is that right? If it is, then there is no solution for me on the link you provided, if it's not how can I find out what it is?

Thanks :)

I had the same problem running my Acer 7730z with an nvidia card.

I tried this

So far (been about 4 days) its not had any flickering in the slightest.

Hope that's of some use to you all.
