mostly harmless

Hardware

 

  • 15" screen
  • webcam
  • modem
  • LAN
  • keyboard and surround, screen surround are white.
  • 250GB hard drive: Toshiba MK25555GSX
  • optical drive: HL-DT-ST DVD-RAM GSA-T50N

Minor issues:

  • optical drive tray wouldn't open — needed to be pressed closed until it gave an extra click; seemed to be easier after a while.
  • power button is slow to respond when running on battery only

Installation

Installed 32-bit Ubuntu 9.10 from the 'alt' CD

No problems.

On start-up, offered the slmodem driver as a 'restricted driver' (see below).

Sound

aplay -l lists the sound chip as ALC622 rev1

MythTV vs lircd

I’ve got an IR receiver plugged in to the serial port, which works with minimyth, but lircd keeps saying
Jan 2 18:33:32 theboxhd lircd-0.8.6[2516]: caught signal
Jan 2 18:33:32 theboxhd lircd-0.8.6[2516]: closing '/dev/lirc0'
Jan 2 18:33:32 theboxhd lircd-0.8.6[3144]: lircd(devinput) ready, using /var/run/lirc/lircd
Jan 2 18:33:34 theboxhd lircd-0.8.6[3144]: accepted new client on /var/run/lirc/lircd
Jan 2 18:33:34 theboxhd lircd-0.8.6[3144]: initializing '/dev/lirc0'
Jan 2 18:33:34 theboxhd lircd-0.8.6[3144]: can't get exclusive access to events coming from `/dev/lirc0' interface
so I followed the instructions at http://www.lirc.org/html/devinput.html to make HAL ignore the IR device (in fact it will ignore any serial device) by creating the following in a new file called /etc/hal/fdi/preprobe/10-ignore-lirc.fdi:






true


 (after getting clues about what key to use from lshal).
Restarting hal and running lshal confirms that HAL is now ignoring the IR device.
Restarting lirc … gives the same result as before. It still doesn’t have exclusive access to /dev/lirc0. Even after a reboot.

MythTV — getting the cards in the right order

Solved the problem without resorting to udev using the info on the MythTV wiki.

And added my solution to that wiki page. Copied here:

Another example (added November 2009, using MythTV 0.22 with a 2.6.31 kernel): a backend with two Hauppauge Nova-S-Plus DVB-S cards and a Hauppauge Nova-T 500 Dual DVB-T card. Adding these module options to /etc/modprobe.d/dvb.conf:

options cx88-dvb adapter_nr=0,1
options dvb-usb-dib0700 force_lna_activation=1 adapter_nr=2,3

makes sure that the DVB-S cards are always adapters 0 and 1, and the DVB-T card’s dual tuners show up as adapters 2 and 3. This is confirmed in the system log, where the adapters are numbered correctly despite being detected in a different order:

$ dmesg | grep "registering adapter"
[    7.163022] DVB: registering adapter 2 frontend 0 (DiBcom 3000MC/P)...
[    9.840541] DVB: registering adapter 0 frontend 0 (Conexant CX24123/CX24109)...
[    9.841996] DVB: registering adapter 1 frontend 0 (Conexant CX24123/CX24109)...
