Slacker installs OpenSUSE 11.4

Posted 06-05-2011 at 04:46 AM by TwinReverb

So I figured I'd try OpenSUSE 11.4 on my netbook (Asus 900A) today, and write down my experience with it as I go.

First, when booting the installer, I noticed that during the configuration phase, when partitioning my hard drive, it picked some odd options (to me), like putting root and /home on extended partitions, etc. I thought to myself, no big deal, I'll custom partition with the root size it had decided (5GB).

hiding the GUI of an application

Posted 06-03-2011 at 02:11 AM by neonsignal

Usability Problems With Unity

I think that the sidebar is really confusing. When you click on an icon, it launches the app. You click on it again, and it brings that app to the top.
