Lenovo Ideacentre Q150 with Ubuntu 10.10 Maverick Meerkat

with 4 comments

My system:
  • Q150 + Nvidia Ion + Ubuntu 10.10 + HDMI + Lan
Wired Network:
  • There are random eth0 errors which cable power is not detected. Simply, shut the system down for 5-10 seconds and reboot.
Nvidia Ion, HDMI:
  • Most of the major issues are related to the Nvidia driver, and the opensource driver does not work in my case (overscanned). This could be fixed by using proprietary drivers:
  • System -> Administration -> Additional Drivers -> Enable restricted drivers
Sound over HDMI, Wifi, XBMC (a nice home-theatre system):
  • This article already covers the issues. I would suggest using XBMC for home entertainment than other media players for better performance.
Google Chromium with Nvidia Ion (fast and energy-wise):
  • The updated version should support the hardware acceleration automatically. In order to get the most updated version read this article.
MPlayer/SMPlayer with Nvidia Ion:
  • I prefer playing TV series on SMPlayer. To enable hardware acceleration and the ability to play HD movies, just do the following:
  1. Open SMPlayer
  2. Options -> Preferences -> General -> Video -> Output driver-> vdpau
  3. Performance -> Performance (bad naming, by the way) -> Allow hard frame drop
  4. Performance -> Performance -> H.256 -> Loop filter -> Skip (always)
  • I can play up to 720p-h.264 movies on SMPlayer. In this case VDPAU is not as fast as I expected because you can still notice the video distortion from the hard frame drop. This could be a bug in MPlayer?. In the mean time, I would suggest XBMC for all media.

  1. I’m having still having problems with eth0 detection on ubuntu 10.10 netbook , Lenovo Ideacentre Q150.
    Tried waiting between power-cycling the system – that didn’t help.

  2. After reboot have you tried “sudo ifconfig eth0 up”?

    FYI, my /etc/network/interface contains the following:

    auto lo
    iface lo inet loopback
    auto eth0
    iface eth0 inet dhcp

  3. For what it’s worth, I have to physically disconnect the power supply between boots to get the NIC to work.

  4. @ffarmer thanks for the comment. I still wonder what causes that NIC failure. If it is network booting feature, probably if it is switched off in the configuration we don’t really need to de-energize the circuit. Anyway, I don’t really want to set the whole thing up again just to be realised :)
