Saving your workspace window configuration in Linux [1102]

I am usually working on a good half a dozen things at any given time and this means that I usually have a good ten or twenty windows open. My chromium currently has a 134 tabs and this is after I  cleaned up and closed all the tabs I no longer need.

Luckily, working in Linux means that I can spread each stream of work into the various workspaces.

Now GNOME 3 makes things a little more complicated with the dynamic workspaces but I’m learning to use it to my advantage

However, with Ubuntu 11.10 Oneiric Ocelot and GNOME 3, I seem to be running into an issue regularly…If I leave my computer for a while, it doesn’t unlock correctly. The screen remains black and I can’t move the mouse to my second screen and the unlock screen doesn’t show up.

Thinking about it, it seems like there might be two screen savers being started but I shall investigate that tomorrow. I have the same issue at both work and home so it is more likely to be related to Ubuntu + GNOME 3 or something about the way I set things up.

I  usually resolve this by logging into the console and here a neat trick for killing all our processes in one fell swoop.

$ kill -9 -1

Another thing I have been doing a bit more of recently is gaming which involves rebooting in Windows.

Both of the above leaves me with a restarted workspace. Starting up the applications pops them all into the same workspace. Chrome is especially a nightmare. I might have 135 open tabs but they are in about 6 windows spread across four workspaces.

It is annoying to have to distribute these things out each time.

Synergy with Linux Server & Mac Client

I  borrowed a mac to try and play with iPhone development. I already have a linux box (running Ubuntu 9.10). Anyone who has used two computers simultaneously know how annoying it is to have two keyboards/mice plugged. I originally anticipated just using X11 forwarding. However, it is an iMac with a big beautiful screen. It would be an absolute waste to not use it.

Vista Guest, Linux Host, VirtualBox, Host Networking – Bridge

One would think that it would be straightforward, work off the bat, or at least have some reasonable documentation. Unfortunately, no!

I needed host networking to be able to access network resources (Samba shares etc.) which does not work if the guest OS is on NAT :-(

Solving it was easy though… I assume Vista is installed as a guest with the guest additions and that your user account is a part of the vboxusers group.

On the linux host, first install bridge utils. I run Ubuntu, so it was as easy as:

$ sudo aptitude install bridge-utils

Next, you need to set up the bridge; again, easy on Ubuntu:

add the following section to /etc/network/interfaces

auto br0
iface br0 inet dhcp
bridge_ports eth1

Add the interfaces to VirtualBox

$ sudo VBoxAddIF vbox0 ‘shri’ br0

Within the VirtualBox Guest settings, choose Host Networking and fo the interface, choose br0

bring the interface up:

$ sudo ifup br0

and start your guest os… et voila, it just works…
