I can't tell because in the meantime I went back to the 'nouveau' driver: up to now it hasn't yet frozen (cross fingers ;-) However, Xorg.?.log showed the module was detected and loaded and this fact is asserted by the following lines extracted from a 'journalctl -xb --boot=-x' (where 'x' was the number of boot when nvidia was installed) > > what does > sudo lshw -businfo -class bridge -class display > report back? > Ok, this is the result with nouveau installed, but it was identical when nvidia was installed (of course, being hw stuff) Bus info Device Class Description ======================================================== pci@0000:00:00.0 bridge MCP89 HOST Bridge pci@0000:00:03.0 bridge MCP89 LPC Bridge pci@0000:00:0e.0 bridge NVIDIA Corporation pci@0000:01:00.0 bridge XIO2213A/B/XIO2221 PCI Express to PCI Bridge [Cheetah Express] pci@0000:00:15.0 bridge NVIDIA Corporation pci@0000:00:16.0 bridge NVIDIA Corporation pci@0000:00:17.0 <-> bridge MCP89 PCI Express Bridge pci@0000:05:00.0 <-> display MCP89 [GeForce 320M] > and the file you created > /etc/grub.d/01_enable_vga.conf > can you pleas list the contents of this file? Here it is (I saved it before removng nvidia): # 01_enable_vga.conf # per modificare i valori del bridge e del display della nvidia # cfr. proprietary-nvidia-drivers-on-mac-with-efi (ask ubuntu) setpci -s "00:17.0" 3e.b=8 setpci -s "05:00.0" 04.b=7 > Note that when I checked, as suggested by the ubuntu link author, with $ sudo setpci -s "00:17.0" 3e.b 08 $ sudo setpci -s "05:00.0" 04.b 07 I obtained the correct values. Some further considrations: While I'm writing this answer I'm recalling to my mind that I was acting in complete ignorance of what all that mean, particularly the 3e.b=8 etc. In the meantime I have desperately searched the web for an explanation of hex structure, which I found a few hours ago. And the only doubt, now, is that I might have first given that setpci instruction with the same values of ubuntu post (05.b=7) and after getting the black screen having corrected to 04.b=7. I am still not sure which value would have been correct and if you know please tell me just for the case I might go back again to nvidia in case of new frequent frozes of nouveau.
