It has been quite awhile since I last spent considerable time in configuring and setting up a Linux system. I have been able to install Ubuntu in all the laptop and netbook,I have been playing for the last few years ever since I moved from Slackware to Ubuntu as my primary desktop system. With the continuous improvement of Linux and OSS platform, installation of Linux is really very easy. Compare with the good old days, where we tend to share experiences of how to install Linux and always need to check up various howto guide before installation, we hardly need to be bother with such steps these days. Everything just seems magically work out of the box. So, the idea of publish some write out on our installation experience seems rather pointless.

Until I need to install Ubuntu into this laptop.

Below is the hardware specification of Ideapad U460:

  • CPU: Intel Core i5-450M Processor ( 2.40GHz 1066MHz 3MB )
  • Memory: 4GB PC3-8500 DDR3 SDRAM 1066MHz
  • Graphic: NVIDIA GeForce 305M, Intel Graphics Media Accelerator HM55 HD
  • Sound: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio, nVidia Corporation High Definition Audio Controller
  • Display: 14.0-inch HD LED Glare 1366×768
  • Hard Disk: 500GB 5400RPM (Western Digital)
  • Webcamera: Yes
  • Wireles: Intel Wireless Wi-Fi Link 1000
  • Bluetooth: Bluetooth Version 2.1 + EDR
  • Input/Output Port: 2 x USB, 1 x eSATA/USB, 1 x VGA, 1 x HDMI, 1 x LAN, 1 x Ethernet, 1 x Mic-In, 1 x Headphone
  • Expansion Slots: 5-in-1 Card Reader
  • Battery: 8 Cell Lithium-Ion Battery

Downloading the CD installer from Ubuntu is easy, and is very fast if done it via bitTorrent network. Formatting and installing of Ubuntu to the laptop is very very easy. Everything seems to work fine straight from default installation. The problem starts to appear when I attempt to setup the graphic and sound of the laptop.

Basically, 2 problems:

  • 1) The graphic would go blank screen after enabling the proprietary NVIDIA graphic driver.
  • 2) No sound in the headphone audio out.

Solution:

  • 1) Ubuntu would correctly detect and install the proprietary NVIDIA graphic driver, but upon reboot, the system would go into blank screen. The solution to solve this problem is boot into bios (press F2 while system boot up), under: “Configuration” -> “Graphic Device”, select “Discrete Graphic” instead of “Switchable Graphics”.
  • 2) Just install the latest ALSA driver version 1.0.23. Follow the guide found here: Upgrade Alsa (1.0.23) on Ubuntu Lucid Lynx 10.04

Things I did not try:

  • 1) the finger print login. Not important to me, I would rather remember password.
  • 2) multi-touch touch pad. Why on earth I would need a multi-touch when I have keyboard and mouse/mousepad?
  • 3) HDMI video out.

Note:

  • There are complains found over the internet about screen brightness problem, which I did not encounter. I suspect, the update and fixes download from Ubuntu after the installation may have resolved the issue.

So far, the system is very stable, no unusual reboot or hardware incompatible issue.
