Windows 7 starter version doesn’t support extended displays

January 12, 2011 1 comment

Shame on Microsoft, really, I have to say this once more, once I found out I couldn’t use dual displays in extended mode (that is, not cloned mode) on my Acer AOD 255 (windows 7 starter installed) which comes with an external VGA connector. Note that I also dual boot ubuntu 10.10 on this little netbook and dual display works flawlessly (in either clone or extend mode). Went online to do a bit of search and only to find out the starter version of windows 7 really sucks on multiple display support.

Ethernet bonding howto in Ubuntu 10.10

January 9, 2011 3 comments

Tested in 64bit environment.

1) echo “alias bond0 bonding” > /etc/modprobe.d/bonding.conf
2) apt-get install ifenslave
3) edit /etc/network/interfaces as follows
# The loopback network interface
auto lo
iface lo inet loopback

auto bond0
iface bond0 inet static
# change the next three lines according to actual network settings
address 192.168.1.200
gateway 192.168.1.1
netmask 255.255.255.0

slaves eth0 eth1
bond-mode balance-rr
bond-miimon 100
bond-primary eth0 eth1
up /sbin/ifenslave bond0 eth0 eth1
down /sbin/ifenslave -d bond0 eth0 eth1

4) either do a complete system reboot or the following:
a) /etc/inti.d/networking restart
b) ifconfig eth0 0 (and ignore the error, this [ and the next ] command will delete what ever ip address that eth0 has been originally set to)
c) ifconfig eth1 0
d) adjust the routes if necessary, mostly the default route needs to be replaced (change to via bond0 instead of eth0 or eth1, for example:
route del default dev eth0
or
route del default dev eth1
)

Regardless which method is chosen in step 4, it’s usually safer to change the network setting through a local console instead of a remote ssh session.
