Rebooting caused theme to look like Windows 95 or Gnome Classic

My PC has recently received a fresh Ubuntu 13.04 install. There is nothing else on the PC apart from a very basic setup of 13.04.

After rebooting, I noticed so many problems with the way Ubuntu looked:

• Mouse pointer very large, blurry
• Applications don't have a global menu bar
• Font is all weird... is it open sans instead of Ubuntu?
• Right click context menu has little coloured icons in it
• Most applications look like Windows 95

I've tried:

• unity-revamp
• unity --reset
• changing the theme from Ambiance and back again
• creating new user account (looks ok in other account, but switching back is the same)
• removing custom themes directories (there were none at ~/.theme, ~/themes)
• Installing proprietary drivers (this made everything much faster and smoother, but didn't fix the weird theme)

Here's some screenshots of what things look like now:

Can someone help my Ubuntu get back to its beautiful self?

A colleague fixed this for me:

We basically went through all hidden directories within the home directory and moved them to a backup folder...

It was after removing ~/.gconf I noticed that everything, slowly, started fixing itself.

Once booted, I first noticed the font was back to the normal Ubuntu font, and then in front of my very eyes the global menu bar popped up to the top-bar, and then the colours popped magically back to life.

The last thing to fix itself, was the mouse pointer, which reduced in size as I was typing this answer.

As much as this fixed my problem, I really don't have a clue why this occurred, or what file within gconf was the culprit...

Removing ~/.gconf didn't fix it for me. I found that my particular case was probably due to a crash of upowerd.

What I did to fix it:

• sudo apt-get install libimobiledevice-utils
• Unplug all USB devices (for me it was a headset, Windows Phone, and iPod)
• Reboot
