Isaac Dontje Lindell's questions

I'm using Ubuntu 13.10 Saucy.

I want to find a way to use horizontal scrolling to switch workspaces. I'm using Compiz 3D cube right now, but I'm not horribly attached to it.

I'm looking for behavior similar to how Chrome works to switch between "Most Visited" and "Apps" on the new tab page using horizontal scroll, but for workspaces.

The only reference I've found to something like this is here.

However, that option isn't available in the current version of Ubuntu Tweak, and anyway it says it only works when the cursor is on the desktop (so I can't do it if I have a window maximized.)

Is this possible?

I'm running 13.10 Saucy. If I didn't enable disk encryption during installation, is there any way to enable it post facto?

I found this, which says that encryption has to happen at install time, but it's also referring to Fedora. I can easily boot into a live disk if there's any way to do it from there.

How can I permanently switch the Caps Lock and Esc key functions in Saucy? I can use this command to do it temporarily (until reboot):

/usr/bin/setxkbmap -option "caps:swapescape"

I tried adding that command as a Startup Application, but it doesn't seem to do anything.

I just did a fresh install of Ubuntu 13.10 (actually, I've done two fresh installs, hoping that trying again would get this working).

I don't seem to have the ability to add or remove bookmarks from Nautilus. The ones that are there by default (Home, Desktop, Documents, etc.) work fine. I can right click on them and rename them. However, I cannot remove any of them. The option is there "Remove" but disabled/grayed out.

The same is true if I try to add bookmarks. I go to "Files -> Bookmarks", and all the bookmarks show up, but the buttons at the bottom to add, remove, or re-order the bookmarks are simply disabled.

What am I doing wrong?
