The second command assigns the video mode to the VGA port (VGA-0). While the third and fourth commands switch the LCD display (LVDS) to 1024x768 mode and the VGA port to the newly created one respectively.

Print cartridge(s) missing or not detected.
It doesn't mean that! You might think that the cartridge is empty or damaged. You couldn't be more WRONG! It just means that HP wants YOU to BUY a NEW CARTRIDGE - but DON'T DO THAT! You cartridge is presumably fine!
Actually you can try to convince the printer that the cartridge is ok by entering the service mode. To do that press buttons in the following sequence:
- Power and Cancel simultanously, then
- Blue, Green, Gray buttons, in turn.
Congrats! You entered the service mode. Now you can read and edit some of the printer settings. Watch the LCD display, it should say sth like:
Now, the color buttons mean:
- Blue: next
- Gray: previous
- Green: enter
Which allow you to browse the menu and options.
In order to cure your cartridge press Blue once. You will see
Information Menu displayed. Enter the menu by pressing Green. Go to
Pen supply, level of Ink (LOI) submenu by pressing 11 times Blue and enter it by pressing Green. Then you can see some ink levels on the display. At this point your job is done. Press Cancel 3 times – it will quit the service mode. And you will notice that the nasty message about the cartridge being missing is gone.
Putting it all together, to reset the message press:
- Power and Cancel simultaneously,
- Blue, Green, Gray, in turn,
- 11 times Blue
- 3 times cancel.
I found these service codes on the web and accidently i figured out that viewing the ink level resets the nasty message. The drawback is that you need to reset the printer pretty much every print job.
It's been about 400 pages since I reset the thing and the cartridge is still operational despite its ink levels being reported as nonexistant.
apt-get source linux-source
It will download a TAR archive into your working directory. Untar the archive and cd into the directory with the kernel source.
Re/Configure the kernel by issuing:
It will ask you to reconfigure all kernel flavours in turn. Reconfigure the flavour you want to alter, not changing the others.
In order to build your kernel (the generic flavour) issue:
CONCURRENCY_LEVEL=2 AUTOBUILD=1 NOEXTRAS=1 skipabi=true skipmodule=true debian/rules binary-generic
After a while you should see deb packages in the parent directory.
If you want to come up with your flavour take a look at: http://mmlinux.wordpress.com/2009/07/30/how-to-compile-kernel-in-karmic/
