We need to do three things:
- pci=noacpi in the kernel option (see the my last blog section 5 boot set up.) If you have still problem try acpi=off, but in this case I have only one CPU core detected. See https://wiki.ubuntu.com/DebuggingACPI
- Set graphics device to discrete graphics since Nvidia Linux driver seems have not yet Optimus support.
- Update the Nvidia driver to 290.10. (280.13 seems not work on this machine. The error is: udev-fallback-graphics main process ($PID) terminated with status 1)
I assume you are still in Optimus or Integrated chip mode. In this mode, you can have X running, so it is a good start.
- I first updated the Linux kernel to 126.96.36.199.
There are two ways: Ubuntu way and direct installation. Ubuntu-way should be later better, but in my case, glxinfo does not work. And the fowllowing error I got.
% glxinfoname of display: :0.0X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 137 (NV-GLX) Minor opcode of failed request: 4 () ...
- Anyway, here is the Ubuntu way for the record. (Currently, this doesn't work, but I hope later this works.)
sudo apt-get purge nvidia-current sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current
sudo apt-get install nvidia-setting
Now you have the driver version 290.10.
sudo cp xorg.conf xorg.conf.mybackup
Note: Section "Device"'s BusID should be "PCI:1:0:0" in my case. The old version of nvidia-xconfig say "PCI:0:2:0" and can not found the driver. Unfortunately, this doesn't work (2011-1-27). glxinfo casts an error.
- The following is not the Ubuntu way, but, this worked
- Download NVIDIA-Linux-x86_64-290.10.run from http://www.nvidia.com/content/DriverDownload-March2009/confirmation.php?url=/XFree86/Linux-x86_64/290.10/NVIDIA-Linux-x86_64-290.10.run&lang=us&type=GeForce
- Get the console!
- sudo apt-get purge nvidia*
- sudo sh ./NVIDIA-Linux-x86_64-290.10.run (I don't install the 32bit compatible OpenGL libs. That might cause a problem. Others I answer yes.)
- Reboot and pray.
- Press F1 on boot time, Config -- Display -- Graphics Device to Discrete Grap. Save and boot.
I hope you can also enjoy the Nvidia card on Lenovo W520.
