My Davicom (tulip) network card isn't working

There is a recorded problem with the tulip driver in the kernel shipped with Ubuntu 6.06. The 'tulip' driver claims the card, but it should be assigned to the 'dmfe' driver.

This problem was fixed in the package for 2.6.15-24.40, and the latest kernel from dapper-security should no longer have this bug.

Manual temporary fix:

sudo -s -H
rmmod tulip
rmmod dmfe
modprobe dmfe
/etc/init.d/networking stop
/etc/init.d/networking start

Manual permanent fix:

Add dmfe to /etc/modules and add blacklist tulip to /etc/modprobe.d/blacklist, such as by issuing the following commands:

sudo sh -c 'echo dmfe >> /etc/modules'
sudo sh -c 'echo blacklist tulip >> /etc/modprobe.d/blacklist'

Firefox Sound isn't working

Ubuntu lists a bug with flash and firefox, which causes firefox to crash when using the esd audio sink. Ubuntu's fix is to disable sound. You can use alsa instead:

apt-get install alsa-oss

Edit the file /etc/firefox/firefoxrc and replace the line

FIREFOX_DSP="none"

with

FIREFOX_DSP="aoss"
