i.e: kernel /vmlinuz-2.6.25 root=/dev/sda3 resume=/dev/sda2 vga=0×0325

Problem: The settings differ depending on your graphics card.
But: There is an easy way: hwinfo

[ sudo ] hwinfo −−framebuffer

Example output:
Mode 0×0307: 1280×1024 (+1280), 8 bits
Mode 0x031a: 1280×1024 (+2560), 16 bits
Mode 0x031b: 1280×1024 (+5120), 24 bits
Mode 0×0305: 1024×768 (+1024), 8 bits
Mode 0×0317: 1024×768 (+2048), 16 bits
Mode 0×0318: 1024×768 (+4096), 24 bits
Mode 0×0312: 640×480 (+2560), 24 bits
Mode 0×0314: 800×600 (+1600), 16 bits
Mode 0×0315: 800×600 (+3200), 24 bits
Mode 0×0301: 640×480 (+640), 8 bits
Mode 0×0303: 800×600 (+832), 8 bits
Mode 0×0311: 640×480 (+1280), 16 bits

Thanks to Gerd [de] for the hint.

It’s a great British sitcom about IT administrators and their weird lifestyle (yes, it’s very exaggerated : ) ).

hp – a well known brand. Description says “Works with Max OS X, Win Vista, XP, 2000″.
Linux wasn’t mentioned, but that’s not unusual at all.

The default xsane backend package (<- v.1.0.19 [delivered with Ubuntu Hardy])
didn’t find a device, so I tried installing the beta release of the hp3900 sane backends (drivers).
This version is still beta status, but got my new scanner up and running : )


HP Scanjet G2710

HowTo:
Get the latest drivers from the sourceforge project:
http://sourceforge.net/projects/hp3900-series/

Unpack the files and change into the new directory:
tar xfz hp3900-series_0.12.tar.gz
cd hp3900-series_0.12/

Install the drivers:
sudo ./INSTALL.sh
application: 2 – SANE Backend
distro: 3 – Ubuntu

Add your username to the scanner group:
sudo adduser your-user-name scanner

Start XSane : )

PS: Fastest and best results with 200 or 300 dpi

Update June 22th, 2008:
I forgot to mention that it only works with resolutions equal and less than 600dpi

New features, that I like:

  • Repositories are very easy to add
  • Hardware detection is great
  • Improved Gui, nice desktop effects
  • Support for WEP, WPA, PPTP, etc. out of the box
  • …

I just installed the system and it was never easier to set up wireless lan or a vpn connection in a linux distribution… Keep up the good work!

Save your prefered video (from i.e. YouTube, MyVideo, etc.) with KeepVid.

When FFmpeg is installed, the conversion in Linux is quite simple:
ffmpeg -i input.flv -ab 128 -ar 44100 -b 900 \
-s 640x480 output.mpg

-b = videobitrate
-ab = audiobitrate
-ar = audiosamplerate (Hz)
-s = framesize width * height
