I upgraded my Intrepid install a couple of months ago to Jaunty, but I haven’t got the chance to blog about it. In fact it’s been a while since I posted anything on my blog. The update is fairly straight forward, and as expected, broke several functions in my lappie, namely graphic acceleration and bluetooth. For fglrx, I suggest you to stick to the ubuntu sanctioned package, available from their repos, since the newest package from ATI broke several things in my box, such as Xinerama 
You can refer to my intrepid post on how to install it from Ubuntu repos
For bluetooth, you still need to install omnibook-source package. The steps to get it to work is almost the same as on my intrepid howto, with a couple of changes here and there. Get everything you need to build a module by opening console and type:
surfer@M5MobileMark-II:~$sudo apt-get install module-assistant build-essential
After that, double click on the omnibook-source file to install the package. Follow the instruction. Next is to build the module:
surfer@M5MobileMark-II:~$sudo m-a a-i omnibook-source
To activate the bluetooth adapter immediately, type:
surfer@M5MobileMark-II:~$sudo modprobe omnibook ectype=14 userset=0 lcd=0 display=0 blank=0 battery=0 ac=0 bluetooth=1
The next thing to do is to get the bluetooth adapter to start on boot. Add the module to the /etc/modules. Open the file by console
surfer@M5MobileMark-II:~$sudo nano /etc/modules
Add a new line, and put omnibook then save. My /etc/modules looks like this:
fuse lp sbp2 omnibook
Next, create script that will be executed on boot:
surfer@M5MobileMark-II:~$sudo nano /etc/modprobe.d/omnibook
….and add the following line to the file
options omnibook ectype=14 userset=0 lcd=0 display=0 blank=0 battery=0 ac=0 bluetooth=1
Save, and reboot. The bluetooth adapter should work after reboot.
To get bluetooth to work after a hibernate, do the following steps :
surfer@M5MobileMark-II:~$ cd /usr/lib/pm-utils/sleep.d/
surfer@M5MobileMark-II:~$ sudo nano 89bluetooth
Put these lines on the file:
#!/bin/bash
rmmod -f omnibook
modprobe omnibook ectype=14 userset=0 lcd=0 display=0 blank=0 battery=0 ac=0 bluetooth=1
Save. Set the file to be executables by :
surfer@M5MobileMark-II:~$ sudo chmod 755 89bluetooth
After that, bluetooth adapter should be able to start after resume
Ever want to run oracle’s sqlplus with crontab? Most of the time, the script won’t be executed, even though you’re already using the right user account. This is because crontab does not source the user’s environment variable when executing the command, and this cause some specific ORACLE variables not having the correct vaules, and in turn caused sqlplus to be unable to find some files required to run.
To solve this, you need to source the environment variables on your script. This is how the crontab script looks like :
$ more gstat.sh
. /home/oracle/.profile
/scripts/gstatsql.sh
and gstatsql.sh contains the sqlplus command that I want to run, while the gstat.sh is the one called by crontab. This is how my crontab looks like :
30 19 * * * /scripts/gstat.sh
With this, crontab will source the environment variables for the user oracle, and sqlplus will be able to run correctly.
