The missing function keys are due to the fact that Samsung N150/N210/N220 are missing from the udev rules:
/lib/udev/rules.d/95-keymap.rules /lib/udev/rules.d/95-keyboard-force-release.rules adding "|*N150/N210/N220*" to the product part of the rules for Samsung in BOTH files, will enable the Fn-up and Fn-down keys. The new product section will look like: ENV{DMI_VENDOR}=="[sS][aA][mM][sS][uU][nN][gG]*", ATTR{[dmi/id]product_name}=="*NC10*|*NC20*|*N130*|*SP55S*|*SQ45S70S*|*SX60P*|*SX22S*|*SX30S*|*R59P/R60P/R61P*|*SR70S/SR71S*|*Q210*|*Q310*|*X05*|*P560*|*R560*|*N150/N210/N220*" Now, you can map these keys to any program setting the backlight (see: http://ubuntuforums.org/showthread.php?t=1397371 post no #) -- SAMSUNG N150 Laptop : Brightness issue https://bugs.launchpad.net/bugs/574250 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
