I installed the Cinnamon edition earlier this afternoon and it's running perfectly. The machine I installed it to is a i7 with Intel graphics so I installed with free drivers.
I have downloaded Budgie to install on my Imac. This machine is an i5 with Nvidia GPU. I suspect that the GPU is failing and if I run it with the Nvidia driver the text is garbled and I get artifacts on screen. The display is fine with the free driver.
The thing is budgie will not boot with the free drivers. I just get a message that lightdm could not be started. All other distros run fine with the free drivers.
