    Screen Flicker Ubuntu 10.04

    I did a clean install Ubuntu 10.04 64bit Dell Inspiron 1545 laptop.
    I get a screen flicker bottom half of the screen every couple of minutes for like one second. I updated things, it's not as bad, but its still there, It only happens like every 20 minutes or so.

    Same thing happened using Fujitsu A1120 with v10.04 x64.

    And, still have the flickering even applied:

    Code:
    echo "i915.powersave=0" | sudo tee  /etc/modprobe.d/i915-disable-powersave.conf
    sudo update-initramfs -u

    Well Ive tried that too it didn't work for me either, so I changed it back.
    As far as I can figure, you and I have the "Intel mobile 4 Series chipset" and thats the problem and I'm not a computer tech.
    This problem was not there in 9.10 and it started with kernel packages 2.6.32-16 and later on some reports. Since there are no drivers to download we are dead in the water until a kernel fix, or at least someone smarter then us can figure this out. I was a little disappointed when i did a kernel update and the fix was not there. It's kind of like hoping your going to win the lottery.
    When no one acknowledges you have a problem or at least working on a solution it makes it even more frustrating.

    I have the same problem. My flickering gets bad if I full screen a video. If I move the mouse around a lot while it's a full screen video, it gets even worse. I have tried the grub change and it hasn't helped. I went to my hardware drivers to see what was going on, but there are none listed except for my wireless card?

    Which grub changes have you tried? "nomodeset", "i915.powersave=0", "noacpi", "noapic"?

    You could try the mainline kernel.
