I just installed the latest Mint KDE on my Mac and I seems to have problems with the graphics board. I can only start the "Recovery Mode" that is selectable in the Grub Menu. If I use the regular way than the systems crashes with colorful stripes on the screen. I already installed the latest nvidia linx drivers but the problem remains. I previously used Mint 13 with Xface and there I had no such problems.
Are there any suggestions for running Mint 13 KDE on a Macbook?
