im having the same issue. Flickering black screen when shutdown, log out, reboot and changing to terminal login (ctrl+alt+F2). cant see anything.

my machine:
acer aspire 4520
nVIDIA GeForce 70000m
Fedora 10 from live cd i686

need solution for a better shutdown and able to use terminal login for some purpose

hey john,
i found a solution to the problem. this will also fix why you dont get the pretty sun on the boot-up process. the problem is that the boot-up and shutdown processes do not support the resolutions that we have our screens set to. you need to add to a line in the the grub.conf file. here is an example of the line that you need to change:
this is all one line
kernel /vmlinuz-2.6.27.19-170.2.35.fc10.x86_64 ro root=UUID=44b5eadd-5550-4a81-94bc-e6100f080599 rhgb quiet vga=792

the difference is the addition of the "vga=792" this changes your resolution to 1280x1024 temporarily. hope this helps

sorry but im a noob in linux. i already tried looking for the "grub.conf" file but i cant find it anywhere. should i change the line, add the line or copy the whole line and paste it somewhere. thank you and sorry if i ask too much. its just that i really careful when messing with kernel.

Comment 4 rolly john 2009-04-07 03:49:15 UTC

and one more question. can i apply this to other linux distro. eg:linux mint. thank you

Comment 5 Dennis Magee 2009-04-10 18:56:03 UTC

grub.conf is in /boot/gurb/grub.conf
you should be able to work on other distros because grub is a separate piece of software independent from the OS
