Gentus Linux comes to mind, obscure distro based on Red Hat (not RHEL mind You) released by now forgotten ABIT, a motherboard manufacturer. I was daily driving it as teenager back in 2001 for couple of weeks until I learned by trial and error how to get windows 98 installed back. Another one would be Mandrake Linux which I was dual booting couple years later.
One reason I loathe DP is how it's handling monitor presence in system when you power of monitor or switch input to 2nd port, it's equivalent of unhooking monitor from pc which screws up desktop layout in most cases. with one monitor it's not a problem but in multimonitor setup windows and task bars start jumping all over the place...
Poland still have chance to prevent becoming 2nd France, can you blame them?
