Presentation resolution on netbooks

July 11th, 2011 by

I recently got ASUS Eee Netbook R051PX, nice little machine, however small annoyance it has when plugged to projectors for presentation is that the default mirrored resolution is just 800×600, the gnome-display-properties does not allow the selection of 1024×768, xrandr comes to the rescue:

Run the following as normal user in terminal to get the required resolution.

xrandr --output LVDS1 --panning 1024x768
xrandr --output VGA1 --mode 1024x768

Note: just in case wordpress eats up – character, there are 2 – before output, panning and mode.

On-Access virus scanning on openSUSE 11.3

September 14th, 2010 by

One of the most useful deployment scenario for Linux in enterprise or educational environment is a fileserver with on access virus scanning, to serve Windows PCs on the network of course. Long ago there used to be samba-vscan that worked very nicely, it went missing in openSUSE 11.2 so dazuko kernel module worked in its place. On 11.3 dazuko is no longer available, enter dazukofs.

KIWI-LTSP multiple image support improvements

September 8th, 2010 by

Savin Alex has been busy working on improving kiwi-ltsp lately. The basic idea behind the new development is easier management of multiple LTSP images that can be served over NBD or AOE.
