Public bug reported:
Binary package hint: linux-image
On a fresh install of Ubuntu my new Samsung N210 plus netbook worked like magic
with one exception:
If I close the lid it suspends or hibernates and if I open the lid again it is
up in half a second - but the screen stays black.
Found a blog that told to try a
setpci -s 00:02.0 f4.b=<brightness>
(actually even if the writer of this blog did own the same netbook his
graphics card was at a different pciid; Brightness ranges between 00
(off) and ff (full brightness). And since this change worked I added a
file named
/etc/pm/sleep.d/99_LightsOn
with the following contents:
#!/bin/sh
case "$1" in
resume|thaw)
/usr/bin/setpci -s 00:02.0 f4.b=50
;;
esac
which resolved the case for me.
Since setting the brightness by the brightness keys won't work either
and booting with the "noapic" or the "nolapic" option will lead to a
complete black screen with backlight off, too, I assume it is a kernel
bug. But feel free to reassign at will.
