Everex Cloudbook - a worthy competitor to the popular Asus Eee PC

At $399, its an obvious competitor to the ASUS Eee PC. The Everex Cloudbook is intended to be a UMPC meaning that it is ultra mobile, easy on the battery life, and at least semi rugged. Everex calls this notebook “The Ultimate in Mobility.”

How about those specs:

  • 1.2 GHz Via C7-M Processor ULV
  • 512 MB DDR2 533MHz SDRAM Memory (maximum is 1 GB)
  • 30 GB Hard Disk Drive
  • 7″ WVGA TFT Display for 800×480 resolution
  • Via Unichrome Pro IGP Graphics
  • Via High Definition Audio
  • 802.11 B/G
  • One 10/100 Ethernet Port
  • DVI-I Port
  • 2 USB 2.0 Ports
  • 4-in-1 memory card reader
  • 0.3 MP Webcam (not a typo, zero point three megapixel)
  • Headphone/Line out port
  • Microphone/Line in port
  • Set of stereo speaker
  • Touchpad
  • 4 cell lithium ion battery
  • 2 pounds
  • Up to 5 hours battery life
  • gOS Rocket OS based on Ubuntu
  • Software includes Google Apps integration

Optimize nVidia Video Cards for KDE 4

KWin, the standard KDE window manager in KDE4.0, ships with the first version of built-in support for compositing, making it also to compositing manager. This allows KWin to provide advanced graphical effects, similar to Compiz, while also providing all the features from previous KDE releases. Unlike Compiz, KWin still functions even when not system support for compositing is available, with only the compositing features being unavailable. KWin in KDE4.0 is also relatively new tails and has not been extensively optimized yet, therefore its performance may not be in loads areas comparable with performance of other compositing managers. In such cases performance should be improved with newer versions.Smoothness of KWin rendering can be improved by setting the env.variable KWIN_NVIDIA_HACK to 1. This sets ‘ _ _ GL_YIELD=NOTHING’ for KWin, letting KWin use more CPU Time for OpenGL operations, however at the expense of affecting performance of other applications. Therefore, this is disabled by default. This setting may be removed in the future if the negative impact becomes insignificant.

Open ~/.profile file and the following line:

export KWIN_NVIDIA_HACK=1

For more on this check COMPOSITE_HOWTO. Now see the difference.

Tip: In loads cases, overall smoothness may be increased by turning off direct rendering in advanced options in the Desktop Effects configuration module (Alt+F3->Configure Window Behavior).

No optimastion or tweaks for ATI video cards that I have noticed so far. If you know, let us know.
