Initiating beta testing of 375a - the hardware is an
Acer Aspire 5750 g
Intel core i5 @ 2,5Ghz
Nvidia GeForce 610m 1GB ; Optimus
Reason for deep testing: Nvidia issue
Booting from flash drive
Network via Ethernet dhcp attached and running;
Elive live screen appears within one second (!)
First a 'normal' installation (without Nvidia) made -
here you are the output of dmesg from the live boot-
(I doubt that is any helpful, but you never know...) :
https://pastebin.com/pSwTEx4g
all seems to run well, even the screen resolution is fine and not any laggy
(no need for the rotten Nvidia crab),
but...
then following the installer advise to install additional Nvidia drivers,
followed all as per advice from the installer = failed:
"The driver could not implemented to the kernel, may be you should downgrade the kernel" - it told me that, aha...
ok, the rough way then:
Boot the computer select Advanced / Recovery mode
done
Login as root from the provided console
done
Make sure that the module "nouveau" is not loaded, using "lsmod | grep nouveau"
seems to be loaded "nouveau" appears in nearly every line shown
if is loaded, you must reboot and press the "e" key in the boot menu
done
to edit the bootloader and add the boot parameter "modprobe.blacklist=nouveau",
where?
I tried to put in before 'fin' - and also at the beginning of the text,
did not work for the first time, just booting into LDM / GUI
worked somehow by second try, I came to the prompt as described from Than.
then press F10 to boot in this mode*
no input possible anymore,hangs after "FAILED to start Light Display Manager":
'Update UTMP about System runlevel changes"
uah.
Will be continued after @Thanatermesis feed back tomorrow then 
PS:
I also tried a direct Nvidia install with the Nvidia InstallApplication (from their site)
Result: It "recommended the 390 Installer, this card is not supported by the 480 Installer" =ok, at least we are more intelligent now ...
