During booting I always hit esc & watch the boot process scroll by. No problems. But I if I let the startup continue in the graphic view, the process hangs just after the progress bar reaches the end. I am left with a slightly glowing screen & have to power down to restart. As long as I hit esc for verbose mode, all is well.
I searched out forum posts & found references to acpi & apci but I didn't find anything that seems to fit my problem.
I have an Acer aspire with nvidia G105m. KDE4 upto date. Nvidia card is not recognised, but am holding off working on it till the 2010 install.
Appreciate any ideas! Tx!!

I edited menu.list to splash=verbose.
