## Welcome to the samsung-backlight wiki! samsung-backlight is a fork of samsung-backlight linux kernel driver. It add backlight support for some of samsung laptops. ## Samsung laptop models Currently supported: * N130 * NC10 * NP-Q45 * R410 plus * R468/R418 * X320/X420/X520 * X360 * R518 * R510/P510 * NF110/NF210/NF310 * N220 * N230 * N350 * R470/R420 * R528/R728 Not tested: * R518 * R510/P510 Have a similar problem, but need more information to add it (if you are owner of these laptops, please add an issue): * X418 * Q1 ## Installation git clone git://github.com/xonatius/samsung-backlight.git cd samsung-backlight make sudo make install On some os you need to add samsung_backlight module to modules list. (f.e /etc/modules) After reboot it should work. Often you need to add acpi_backlight=vendor to the kernel boot options, to makes your system work with backlight. (F.E. In ubuntu you had to edit /etc/default/grub and add the acpi_backlight=vendor to the end of GRUB_CMD_LINUX_DEFAULT line and then run update-grub) ## Other samsung laptop models If you've got samsung laptop with intel graphics card and it hasn't supported backlight control, you could create an issue with "lspci -nn" and "dmidecode -s system-product-name " information. ## Thanks * Thanks nikobockerman for the information and patch for NF110/NF210/NF310 laptops. * Thanks Alberto Mardegan for R410 laptops patch and solution for acpi_backlight problem.
