I install Ubuntu 14.04 LTS on my Eeepc 1101HA with processor Intel Atom CPUZ520 and I have some problems:

  1. Screen is flicking, shacking.....
  2. Video doesn-t work, is very slow and impossible to see anything.
  3. Audio doesn/t work either, it jumps....
  4. Once the pc go to sleep I can~t restart, without shutting down and turning on again.

I have no experience with Ubuntu at all, but I so happy to get out of Windows that I will try hard to stay with Ubuntu. Thanks in advance for any help!

use these values to try to solve

  1. Screen is flickering, shaking: edit or create /usr/share/X11/xorg.conf.d/00-modesetting.conf and add

    Section "Device"
        Identifier  "gma500_gfx"
        Driver      "modesetting"
        Option     "SWCursor"       "ON"
    EndSection
    
  2. Video doesn-t work, is very slow and impossible to see anything: edit or create /usr/share/X11/xorg.conf.d/00-modesetting.conf and add

    Section "Device"
        Identifier  "gma500_gfx"
        Driver      "modesetting"
        Option     "SWCursor"       "ON"
    EndSection
    
  3. Audio doesn/t work either, it jumps: edit or create /etc/pulse/default.pa change

    load-module module-udev-detect
    

    to

    load-module module-udev-detect tsched=0
    
  4. Once the pc go to sleep I can't restart, without shutting down and turning on again.

    edit or create /etc/pm/config.d/gma500 add

    ADD_PARAMETERS='--quirk-vbemode-restore'
    

I hope you solve with this. Keep on gma500 with linux has poor performances.

Good luck!

You may have a too weak CPU and graphics for videos.

You can try a tweak that helps some intel graphics chips, UXA acceleration.
This should increase the performance, but there seem to be issues with the login screen with this fix.

Edit (or create) /etc/X11/xorg.conf as follows:

Section "Device"
            Identifier "Intel Graphics"
            Driver "intel"
            Option "AccelMethod" "uxa"
EndSection

Then reboot the system.

Another way would be to try a lighter linux spin like lubuntu.
