If you are like Diatribex or me, after you installed the latest Ubuntu, some things just didn't work™.
However, the list of non working things with the Intrepid Ibex has shrunk...
Here it goes: how I got this lappy to an almost fully working state with Ubuntu Intrepid Ibex. This is my experience with Ubuntu 8.10, and it may be useful to you.
Sound: Working out of the box with the Ibex.
Video: Works well with nVidia 180 drivers. Please, note that the bug with Suspend to RAM/Suspend to Disk and nVidia 180 drivers only affects GeForce 8xxx, 9xxx and GTx-xxx users. Your nForce 430/GeForce 6150 will suspend and hibernate, and resume, properly. Use the Ubuntu Restricted Drivers manager.
Wireless: Your best bet is with the b43 free drivers, and fw-cutter. It works for me a lot better than Broadcom STA proprietary drivers. You can install it through Ubuntu Restricted Drivers manager, with ease.
Multimedia keys, remote control: They do not work reliably until you configure them properly. But wait, in the Ibex, don't touch /etc/X11/xorg.conf and do not use esoteric solutions. You can do it easily.
1. In your GNOME menu, go to the Preferences menu, Keyboard. Then choose the model of your keyboard. There's no Pavilion tx1000 there, but don't worry: select another HP Pavilion or Omnibook keyboard model. Under KDE, go to the System Settings app, then click under "Country and Language" (the UN flag), You will see three icons in your left-side panel. Click on the keyboard, and select "HP Pavilion zt1100". That worked for me.
2. Configure your keys. At least GNOME and KDE 4.2 will configure several multimedia keys for you.
Don't worry about the remote: it's a low level remote that only "press keys". You won't need drivers for it, it will work.
Fingerprint scanner: It should be as easy as:
$ sudo apt-get install fprint_demo libpam-fprint
$ sudo adduser <user> plugdev (to give that user access to the fingerprint scanner)
Later, if you want to, you may follow a howto about logging in with your finger. I advise against it. There is no good support, neither in kdm nor gdm.
Card reader: It works out of the box.
TV Out: Working. Press Fn+F4. You can configure it through nvidia-settings. Don't forget to install it!
Touchscreen: It's an eGalax. Please, do yourself a favor and if you are using Ubuntu Intrepid Ibex, do not follow those eGalax howtos, do not install proprietary drivers, do not configure your xorg.conf, let the Ibex do all the work. Simply issue this:
$ sudo apt-get install xserver-xorg-input-evtouch
and restart X. If you don't have luck, you'll have an uncalibrated touchscreen; if you have luck, you'll have an autocalibrated touchscreen, if you don't have luck, run ev_calibrate and FOLLOW CAREFULLY THE INSTRUCTIONS.
Pay attention: the touchscreen behaviour when the screen is rotated is BUGGY. The upcoming evtouch 0.8.8 will make, at last, an usable rotated screen.
Side buttons: This is more complicated. You may have read some howtos about making work two of the four buttons. Those howtos are useless with the Ibex: the kernel does not recognize accurately those key presses. The real support comes through a kernel module, QuickStart, available at http://quickstart.sourceforge.net . This will give you real support through ACPI, and allows launching apps through that interface. It won't work, because you need special scripts, and neither the app nor Ubuntu provides them.
If you want to use that, you must know how to compile software. Get build-essential.
$ sudo apt-get install build-essential
Follow the instructions. Read the README!
Modem: This won't work under Linux, but is near useless with Windows Vista, so, at least we are on par with them!
