I have a Lenovo 460 with Ubuntu 11.04 on the machine. I am having similar issues where I am unable to boot into the new kernel, unless I am plugged in to the AC power adapter I have no issues booting into the OS. I have installed the latest graphics driver from AMD for my ATI switchable graphics.. Following this line-up to get the driver to properly install I had to Install the prerequisite packages:

If you are using the x86_64 architecture (64 bit), be sure to install "ia32-libs" on your machine, if you do not it will not function
$ sudo apt-get install ia32-libs
Download the latest Catalyst package.
This package contains both the 32-bit and 64-bit driver. Current Version is 11.6
$ cd ~/; mkdir catalyst11.6; cd catalyst11.6/ www2.ati. com/drivers/ linux/ati- driver- installer- 11-6-x86. x86_64. run installer- 11-6-x86. x86_64. run
$ wget http://
$ chmod +x ati-driver-
Create .deb packages.
$ sudo sh ./ati-driver- installer- 11-6-x86. x86_64. run --buildpkg Ubuntu/natty
Install .debs.
$ sudo dpkg -i fglrx*.deb
Generate a new /etc/X11/xorg.conf file
Create the ATI version of the Xorg.conf file.
This is a Generic Configuration... This works great for my machine which is a Lenovo Y460
$ sudo aticonfig --initial -f
After just reboot your machine
After following this proceedure I am still unable to start Ubuntu without having to be plugged into the wall... I hope the fix will come soon...
