====== Hewlett Packard TX1250ea and Linux ======

* Ubuntu 8.04 (Hardy Heron) relieves most of these problems. There is still the need for NDIS. *

The Hewlett Packard TX1250EA is a bit of hassle to set up for Linux. So far its all up and running with the exception of the fingerprint scanner, which is recognised but I don’t know of any Linux software that supports biometrics.

<note important>I don't have one of these anymore, so this information is purely historical.  I'm keeping it up here incase its useful to someone.</note>

===== Booting the Live CD =====

At the menu, select F6 and add the following lines to the kernel:

  noapic acpi_irq_balance irqfixup irqdebug pci=biosirq pci=nomsi acpi_osi="!Linux" acpi_os_name="Windows 2006" noirqdebug

===== Installing =====

I kept a copy of Windows Vista, so used Vista’s partitioner to reduce the first partition. I made two partitions - swap and root.

After rebooting, the first hurdle as always is wireless.

===== Wireless =====

I used the ethernet connection without any problems and downloaded ndiswrapper and these Windows XP Broadcom drivers. I didn’t need to blacklist the bcm43xx module, it wasn’t loaded.

Unzip the drivers:

  unzip -a R151517.EXE

Then load the ndiswrapper module:

  sudo ndiswrapper -i bcmwl5.infsudo ndiswrapper -l

This will not automagically load at boot time, so you need to do:

  sudo -s echo ndiswrapper >> /etc/modules exit

===== Sound =====

Add the following to ''/etc/modprobe.d/alsa-base''

  options snd-hda-intel index=0 model=3stack position_fix=0 single_cmd=0

I had to reboot here, reloading ALSA didn’t cut it. I also had to play around with the sound settings to get the sound unmuted. It's also worth mentioning here that the latest version of ALSA used in Fedora Core 8 seems to support the soundcard off the cuff and supports the volume control mute button colour changing.

===== Webcam =====

Webcam works with Ekiga, as long as you select V4L2.

===== Touchscreen =====

First, you need to download the driver from the [[http://210.64.17.162/web20/TouckDriver/linuxDriver.htm | manufacturer]]. Then copy the driver to the right location:

  sudo cp egalax_drv.so /usr/lib/xorg/modules/input/.

Lastly, insert the following into your ''/etc/X11/xorg.conf'':

<code xorg_conf>Section "InputDevice"
        Identifier      "EETI"
        Driver          "egalax"
        Option          "Device"        "/dev/usb/hiddev0"
        Option          "Parameters"    "/etc/egalax.cal"
        Option          "ScreenNo"      "0"
EndSection
Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          "Default Screen"
        Inputdevice     "Generic Keyboard"
        Inputdevice     "Configured Mouse"
        Inputdevice     "Synaptics Touchpad"
        InputDevice     "EETI"          "SendCoreEvents"
EndSection''</code>

When you restart the X server, then run the TouchKit utility from the downloaded driver tarball to calibrate.

Lastly, you need to blacklist a few things or it wont work on reboot. Edit /etc/modprobe.d/blacklist:

  blacklist usbtouchscreen blacklist tkusb
