The problem
As Described in X/Troubleshooting/IntelPerformance, some laptops with intel graphics hardware experience a serious performance degration after upgrading from intrepid to jaunty. The reasons for that are already explained on that page. This page explains how to revert the driver to the version in intrepid.
Installing the package
Add the following lines to your /etc/apt/sources.list:
deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
See https://help.launchpad.net/Packaging/PPA#Adding%20a%20PPA%20to%20your%20Ubuntu%20repositories for additional information how to add GPG keys to your system.
Install the driver:
$ sudo apt-get update $ sudo apt-get install xserver-xorg-video-intel-2.4
Now you should be set. Restart X and see if the graphics performance from intrepid is restored.
Do I need to change my xorg.conf file?
Rolling back
If the driver does not work for you, or is not better, you should rollback to the original Ubuntu one. Remove the two lines from /etc/apt/sources.list again, and install the original one again:
$ sudo apt-get install xserver-xorg-video-intel
If X.org does not start at all, you should change to a text terminal by pressing Ctrl+Alt+F2, logging in, and use "sudo nano" to edit /etc/apt/sources.list. After installing xserver-xorg-video-intel, restart the computer with "sudo reboot".
Results
If you have tested the package, please report your findings (broken|same|better) and also your PCI ID:

Works perfect now, thank you |

compiz/3d performance is comparable to intrepid, even planet-penguin-racer is playable again |
[8086:2a42] (rev 07) |
Performance improved |
Lure |
much better performance than 2.6 driver with EXA+greedy or UXA, only problem is that it gets physical size of my 12.1" panel wrong (have to use xrandr --fbmm to fix it manually) |

Significant improvement compared to previous state. Fullscreen video as well as compiz-fusion effects are functioning and fast. |

Much better performance although I'm unsure of whether it's quite as good as it was in Intrepid. |

compiz/metacity performance is back on par with Hardy (I didn't test Intrepid). |

Performance completely restored |
VMC |
compiz/metacity performance is the same as Hardy (I also had issues with Intrepid). |

Performance Completely Restored |

DRI: Check. Compiz (or Metacity Composting): Check. Videos playable on youtube and totem: Check. Tearing and corruption: gone. Still a little slow on full-screen refreshes (min/maximizing windows), but this driver is a godsend for this chipset, which is awfully laggy and has no DRI in Jaunty's default 2.6 driver. |

Pretty sure it's performing better than Intrepid |

Same performance I had in Intrepid. Great fix |

Videos are playable again, compiz is still slow, but not a lot compared to 2.6 driver. Still, there may be even more improvements with Kernel 2.6.30 |

Restored-ish |
Zorael |
Roughly the same as I had in Intrepid, ~6-7x what I have with 2.7 drivers from git. A+, would download again. |
[8086:2a02] (rev 03) |
Slightly worse |
Laurent |
With the normal Jaunty driver, at least with no open Windows, the Compiz effects were fluid. Now, I experiment lack of performances even with no open windows. Apart of that, no change (even after reboot). |
[8086:2a02] (rev 0c) |
Performance worse |

PPRacer was about 18-20 FPS with the 2.6 driver + greedy migration and 4-6 FPS with 2.4. Everything else was choppy all around so I reverted back to 2.6. Xorg continues to hog 30% of the CPU. |
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 0c) |
Xorg uses 30% CPU, like the 2.6 driver does when used with no UXA option. Under 8.10 all was fine. |

"Desktop effects could not be enabled" (Compiz). Full screen video performance okay for about half a second, then screen dims and full screen videos are jerky. Was fine with Intrepid |

rollback made desktop effects even slower, went back to 2.6. Everything was fine in 8.10 |

No improvement |

No noticeable improvements. Unable to activate Desktop Effects with either driver (HP 6710b, X3100). It seems that the picture is shaper/clearer with the 2.4 driver installed. |

Unchanged |

Metacity performance is greatly enhanced. Compiz still won't run because the device is blacklisted (skip_checks doesn't help): http://wiki.compiz-fusion.org/Hardware/Blacklist |
