Hello,
I tested Slitaz-5.0 64 with a live CD. As the result convinced me, I decided to install it of the hard disk using the TazPanel installer.
I chose a double boot Linux/Windows, the Linux part being store onto 3 partitions /dev/sda6 for the system /dev/sda7 for /home and /dev/sda5 for the swap.
When rebooting, the first steps seem OK but when the screen manager is involved (startX ?) then the screen remains black...
My laptop computer is a Dell Latitude 820 with a screen definition of 1920x1200
