first of all sorry for my bad english.
i'm running mint 10 on my notebook with a geforce 8400m gs inside.
a few days ago i upgraded my system to kernel 2.6.35-32-generic.
after a reboot it just gave me a command line on tty1.
i installed the newest nvidia driver (295.40) but it did not solved the problem.
first neither nvidia-current nor nvidia-173, nor *-185 solved the problem.
now nvidia-current works (do not know why) but i'm not able to activate desktop effects.
when i run nvidia-settings it tells me that i "do not appear to be using the NVIDIA X driver...".
running nvidia-xconfig as root did not affect anything.
lsmod says that nvidia driver is loaded.
i'm also not able to install another driver by using "additional hardware drivers".
