I installed sometime ago Solus in my Imac 24'' early 2009, CPU Intel core 2 Duo 2,66GHz, RAM 4GB 1067MHz DDR3, NVIDIA GeForce 9400 256Mb and everything was perfect.
A couple of weeks ago I did the requested upgrades and since then, the computer is starting, once I log in, just after getting the desktop and the typical "dling", monitor switch to black and I cannot do anything else, but switch off the computer.
Do you have any suggestion before to reinstall the OS?
The same installation and upgrades have been done in my MacBook Pro retina 15'' early 2013, CPU Intel Core i7, 2,7GHz, 16GB RAM 1600 MHz DDR3 and everything works properly.
Thanks in advance for any help/suggestion
