Any Linux Mint release is only as good as its parent Ubuntu release therefore things do not bode well for Linux Mint 11 as it is based on Ubuntu 11.04 which it has to be said is dreadful. I remember similar problems with Linux Mint 6 that was based on Ubuntu 8.10 which had multiple bugs but eventually most of these were addressed so Linux Mint 6 improved because Ubuntu 8.10 had improved. All bugs in either Ubuntu 11.04 and Linux Mint 11 can be reported to Launchpad where fixes and workarounds can also be found. This may need enabling a third party ppa.

I am currently putting Linux Mint 11 RC through its paces on one of my testing Hard Drives and seeing as it is a development release it would be unfair to draw any absolute conclusions just yet.

I thoroughly recommend Linux Mint 9 LTS which is built upon Ubuntu 10.04 LTS (Long Term Support) its easy to install and easy to use plus it comes with much of the software you are likely to need preinstalled

Linux Mint 9 LTS can also be run direct from the LiveCD from Boot without touching your Hard Drive
