Ubuntu 12.04 impressions

Some quick impressions of Ubuntu 12.04:

• dist-upgrade went smoothly, no issues
• xubuntu/xfce seems to have survived so far without noticeable changes
• bluetooth.h is broken, it's using GNU extension typeof which conflicts with -ansi switch
• libusb-1.0 stopped working in xboxdrv (might be xboxdrv bug)
  
• Emacs ignores things set in .Xdefaults, had to use (set-default-font "Inconsolata-10.5") to get my old font back
• have some anti-aliasing problems after playing around with Gnome3, KDE and Unity
• BGR font subpixel rendering is still broken, you get RGB instead (patch is available)
  
• volume control in XFCE4 is still broken, but fixable
• lots of crash dialogs pop up due to some background thing crashing
• default gtk3 theme under XFCE4 still looks like crap and there isn't a proper way to fix that via GUI, only via a workaround, haven't yet found a Gtk-3.0 theme that replicates the Clearlooks theme
