2.6.28.8 Kernel for Alix 3d3 with joystick module

I wanted to add a kernel module for my Alix 3d3 but I figured I would just build a more current kernel for the Voyage Linux 6 installation instead.  Because I am a total weenie, I got excited about a cool program called KernelCheck.  It’s basically a GUI for building configuring and packaging (yes Debian packaging!) the latest greatest kernel from kernel.org.  I built the kernel from my Ubuntu machine using the latest config file from the Voyage kernel, enabled the joystick module and installed the resultant .deb in Voyage.  w00t!
linux-image-2.6.28.8-ultimate_2.6.28.8-ultimate-10.00.Custom_i386.deb

headers if you need ‘em :

enjoy!

New HP 2710p and Notes

HP 2710p Stock image

Recently, I bought a nearly new HP 2710p.  I immediately formatted the HD and installed Ubuntu Hardy!  I am very pleased that nearly everything works! Suspend and resume with accelerated graphics and rotation was something I really wanted with my TC1100. I was lucky that this machine was configured with and Intel 4965 AGN card and a WWAN card (which I have not yet activated).  The 2710p is very much like a super-charged TC1100 with dual-cores and other modern conveniences like a fingerprint scanner and a smart-card reader.  Mine did not come with the webcam though I don’t think I’ll miss the feature much. Battery life is very good and the design is very clean. Removing the annoying palmrest stickers required Goo-Gone, but the finish was unharmed. Here are some notes about getting this bad-boy configured in Ubuntu:

Some things that seem to be missing are:

  • Wacom support, which I found HERE (gentoo hardware wiki)
  • Screen Rotation: Make a script called rotate.sh

$ nano ~/rotate.sh
with the following contents:

#!/bin/bash
#script by Francisco Athens modified from Gentoo Wiki Intructions:
#http://gentoo-wiki.com/HARDWARE_HP_Compaq_2710p#Brightness_and_Rotation
#get current setting
testrot=`xrandr -q |grep LVDS | awk '{print $3}'`
#test if screen is rotated in protrait mode
if [ "$testrot" = "800x1280+0+0" ];then
#optional kill any old xvkbd instances so that
# fresh one can load in the correct place in the screen
#killall xvkbd
xrandr -o normal
xsetwacom set stylus rotate 0
xsetwacom set eraser rotate 0
else
#killall xvkbd
xrandr --output LVDS --rotate right
xsetwacom set stylus Rotate CW
xsetwacom set eraser Rotate CW
#optional: put xvkbd on the bottom of the screen
#xvkbd -always-on-top -geometry 800x150+0-0
fi

chmod +x ~/rotate.sh

  • Kernel Panic on lid close! This is a big issue, but I found the solutution HERE (Ubuntu Forums)

I edited my /etc/rc.local:
first make sure the path is correct
$ ls /proc/acpi/video/
there should be only one folder, so in my case for “C09A” add this line to /etc/rc.local:

echo "1" > /proc/acpi/video/C09A/DOS

before the “exit 0″ line

  • Fingerprint Reader Support can be found HERE
  • Current Ubuntu Hardy 2.6.24 iwl4965 driver appears to have problems connecting to TTLS/PAP 802.1x networks (sigh) as reported HERE (intel linux wireless forums).

The real $100 Computers? (Part 1)

Although was really excited about getting our family an XO, it turned out to be a little slow in the long run. My daughter had been using our desktop and laptops for soem time before we bought the XO, so she was naturally a little spoiled by them. There are other ways to provide a cheap computer rugged enough for the kidlets and with enough power to run GNU/Linux apps and flash based websites almost instantly. My kids love Tux Paint and UpToTen.com has lots of fun games, songs, etc for kids even to young to navigate a mouse well. But I don’t really want them mashing on our laptop keyboards (with fragile harddrives beneath) and they arent really comfortable on our adult sized desktop arrangement.

ramline 510

I bought a Ramline 510 from eBay over a year ago with the idea that my kids would have a small, rugged machine that was cheap and still powerful enough to run some games, browse the net with flash and video streaming. The device was $100 and had some nice basic features:

  • 500 Mhz P3
  • 128MB Ram
  • ATI Mach 64, 8MB VRAM (DRI in Linux, yes!)
  • USB v1 – one slow port… but enought for a kb and trackball
  • 5 Gig HD (not terribly useful and replaced by a spare HD) I now use the 5GB drive instead of a live CD to install Ubuntu on other machines..
  • 10″ Touchscreen (took some tweaking to align)
  • Magnesium chassis/case and rugged design

Not to shabby for a C-note. Read on for the tale of adventure…

Also selling my TC1100…

TC1100

Selling my XO has motivated me to also offer my TC1100 for sale. It’s a great machine with lots of features like EDR Bluetooth (supporting A2DP Stereo Headphones) Intel B/G wifi, NVidia Geforce4 2go, pressure sensitive Wacom digitizer (not a sloppy touchscreen) and extra stuff like spare battery, DVD-CDRW and a new stylus pen with eraser.  One of the best designs for a tablet I’ve ever used with the CPU/HD behind the screen and not under the KB so lap and arms dont heat up.  Hope it goes to a good home. Runs Ubuntu quite nicely too!

Selling my XO

francisco’s OLPC XO

EDIT: IT IS NOW SOLD…thank you..

I’ve posted my XO laptop for sale on eBay. It’s a great device to hack on and a bit of computing history that I’m rather loathe to part with. I’m selling it because I need the funds to upgrade another machine. I’m flashing it to the latest stable release, but for FLG blog readers I will also install XFCE to it if you wish.

Swapping tablet network cards

This week I wanted to swap my fussy Atheros ABG network card in my HP TC1100 to an Intel based BG 2200 card. HP makes this a little more difficult with a BIOS lock that requires HP branded cards. There are some folks on EBAY who are applying a hack to make the cards work or selling HP/Compaq cards. I bought one of these cards from a seller named diznavis (eBay.com) and it works great. Thanks! Just thought I’d give props here.

Linux drivers for the Intel cards are very stable compared to the current madwifi, though they have new project underway called ath5k.
