Installation
Normal CD installation works fine. However, if Optimus is enabled, it may require a hard reboot upon completion.
Kernel
- Kernel 2.6.38-8 is the shipping kernel with Ubuntu 11.04. It is buggy. For example, a common issue is to see kworker constantly hit 20% cpu when running top.
- Upgrade to a newer kernel by going to [1] and downloading the headers, image, and _all files for your type of machine. Install them (you can just double-click in the UI if you don't know the commands). Reboot.
Optimus
- BIOS
- The OS Detect option does not work. If enabled, it will present Optimus to Ubuntu.
- If graphics are set to Optimus, Ubuntu will default to using Intel graphics.
- If graphics are set to Discrete, Ubuntu will default to using Nvidia. If dual-booting windows, this will cause problems with the default lenovo system image - possible (untested) fix is to manually reinstall nvidia drivers in windows.
- If graphics are set to Integrated, Ubuntu will default to using Intel graphics.
- The current kernel provided by Ubuntu conflicts with the Nvidia driver. Until Ubuntu upgrades to a newer kernel, you must manually install one.
