Adobe just released their next beta of Flash Player 9 for Linux. Works great on my Ubuntu. Just download the tar.gz from the website and plop into ~/.mozilla/plugins/ .

I have been running the new Ubuntu 6.10 for a few weeks now on my Thinkpad T42, and it is rock solid so far.

The only issues I have been having is switching the network settings through the Administration -> Networking application. It does not want to see my 802.1x wireless connection by default, so instead I had to do the following:

sudo vim /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf.local

And my wpa_supplicant.conf.local file looks like this:

# WPA-PSK/TKIP
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1

#For WPA-PSK network
network={
ssid="SSID"
key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP
psk="encrypted_password"  }

# For 802.1x network
network={
ssid="SSID"
proto=WPA
key_mgmt=WPA-EAP
pairwise=TKIP
group=TKIP
eap=TLS
identity="myemail@email.com"
ca_cert="/home/me/certs/myca.pem"
client_cert="/home/me/certs/my.pub"
private_key="/home/me/certs/my.pem"
private_key_passwd="mypassword"
priority=1  }

#For any network
network={
ssid=""
key_mgmt=NONE
}
