Script for fixing wifi and sound after kernel upgrade

I've made a small script I'd like to share. I installed xubuntu on a friends netbook, and made this script to be run manually or through rc.local to compile and install wifi and alsa after an upgrade of the kernel.The script checks to see if the kernel version has changed, so it only compiles files when you have a new version of the kernel running.

I think it's a nice way to install ubuntu/xubuntu on someones computer without them beeing dependent on you after each security update of the kernel.

It relies on the fact that you have allready followed the guide on https://help.ubuntu.com/community/AspireOne and have a directory with the source for the wificard. Move this directory to the /usr/src/modules directory or change the maddir variable in the script

Code:

#!/bin/bash
#/usr/local/sbin/wifialsa
maddir=/usr/src/modules/madwifi-hal-0.10.5.6-r3835-20080801
madkern=$maddir/madkernel
touch $madkern

if [ $(uname -r) != $(cat $madkern) ]
then
	#wififix
	cd $maddir
	make clean
	make
	make install
	uname -r > $madkern

	#alsafix
	m-a prepare
	m-a a-i alsa
	alsa force-unload
	depmod -ae
	modprobe snd-hda-intel
fi

Save this script as /usr/local/sbin/wifialsa and then run

Code:

chmod +x /usr/local/sbin/wifialsa

You can also add the line

Code:

/usr/local/sbin/wifialsa

to the end of /etc/rc.local to run the script at boottime. When placed in rc.local the AAO boots normally and the modules are compiled in the background, so the wifi and sound modules get automagically repaired after a few minutes while you use the computer.

 

Awesome, I wrote one too, but your script is better!

 

Thanks a lot for this! Will make this script myself after work.
