ok, i tried the workaround once again. i dont exactly have problems with flickering but how i told before, i cant control brightness with fn-keys + hibernation sometimes crashes...
so here is what i did by following the workaround (after updating the whole system):
1) in /etc/default/grub following line modified from
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash'
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor intel_idle.max_cstate=0"
2) sudo update-grub; sudo update-initramfs -u
3) added the following text to the end of /etc/modprobe.d/blacklist.conf: blacklist samsung-backlight
4)edited /etc/rc.local and paste before the "exit 0" statement: modprobe samsung-backlight
5) created a file called /etc/pm/config.d/unload_modules containing: SUSPEND_MODULES="samsung-backlight"
i also tried to uninstall an reinstall samsung-backlight etc, doesnt work as well...
im using a samsung n220 marvel plus with ubuntu 10.10.
