Adding a non-detected modeline in ubuntu as default

Pat McKay — Fri, 17 Dec 2010 02:39:36 +0000

I adapted the procedure I found here to make my old Samsung Syncmaster 192N work at its native resolution. It is running through an old projector on the ceiling, which I’m sure is what is breaking the autodetection.

cvt 1280 1024 75

That returned: # 1280×1024 74.90 Hz (CVT 1.31M4) hsync: 80.30 kHz; pclk: 138.75 MHz
Modeline “1280x1024_75.00″ 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync

Added these lines to /etc/gdm/Init/Default:

xrandr –newmode “1280x1024_75.00″ 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync

xrandr –addmode VGA-0 1280x1024_75.00

xrandr –output VGA-0 –mode 1280x1024_75.00

Now it starts out at the correct resolution at startup, regardless of the state of the projector.

Restart Scalix webmail service quickly

All you need to do is touch the web.xml file.

Our example:
touch /var/opt/scalix/sx/tomcat/webapps/webmai/WEB-INF.web.xml

Windows XP Activation Loop

Pat McKay — Mon, 30 Aug 2010 16:13:36 +0000

Windows XP can get stuck in a loop where it wants to be activated, then when you proceed it says it is already activated and logs you out. Here is a safe mode fix from Microsoft that worked today:

Vmware: “SIOCSIFADDR: No such device eth0″ after cloning

Pat McKay — Sun, 20 Jun 2010 18:34:26 +0000

from: http://muffinresearch.co.uk/archives/2008/07/13/vmware-siocsifaddr-no-such-device-eth0-after-cloning/

This is specifically for ubuntu.

sudo mv /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/70-persistent-net.rules.old
sudo reboot

May need to edit /etc/network/interfaces eth0 or eth1 to match detected adapter, restart the network, and it should be back to normal.

Adding a New Mailnode in Scalix

Pat McKay — Tue, 09 Mar 2010 23:46:22 +0000

This needs to be done after adding a mailnode to enable outlook connector and webmail. This was sent to me by Scalix support.

Add the mailnode first within sac.

The rest is done from a terminal.

To get a list of your mailnodes:

omshowmn -m all

The name displayed against two asterisks ** is name of primary mailnode
Replace mailnode with new mailnode name, and primarynode with your primary mailnode name.

omaddbb -s "mailnode"
omdelacln -t b -l ":mailnode" -g admin
omdelacln -t b -l ":mailnode" -g local
omdelacln -t b -l ":mailnode" -g default
omaddacln -t b -l ":mailnode" -g admin -c visible
omaddacln -t b -l ":mailnode" -n "*/mailnode,*,*,*" -c create read subfolder editown deleteall contact visible
omaddacln -t b -l ":mailnode" -n "Proxy-Folder Admin /primarynode/CN=Proxy-Folder Admin" -c create read subfolder editown deleteall contact visible

I did find/replace with a text editor and drag-n-drop into a terminal window. It took longer to type this up!
