Comment 45 for bug 173418

Not sure how relevant this might be to most of you but I also had the same problem. Installing the nvidia-glx-new driver or nvidia-glx driver and restarting crashed xorg and I had to either type "sudo dpkg-reconfigure -phigh xserver-xorg" in a virtual terminal or use bulletproof X to reconfigure the display for a different driver. By the way I have a nvidia 7100 graphics card.

I also had an issue with the hardy heron kernel 2.6.24.16 not detecting my wireless card (Aironet/Cisco 340) after a long delay of about 2 minutes in the booting process before finally starting the X session. A bug report and fix for this issue is filed under https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/173418 . The workaround there fixed my wireless connection issue perfectly well. I then installed nvidia-glx-new again, restarted my computer and managed to login as normal. I also managed to get compiz-fusion with full 3d effects working as well :).

As stated in the workaround, "I went in the /lib/modules/2.6.24-xxx/modules.alias and I commented out the first two occurrences of AES that link to padlock and geode hardware".

Now the issue seems to be the occurrences of AES that link to padlock and geode in the modules.alias file that stop the kernel from loading some device drivers.

 This worked for me, hope it works for everyone else.
