I use the kernel module samsung_laptop for laptop Samsung 300V4A-A05. Because of this, the module brightness control does not work properly - it is only possible to decrease brightness but not increase. By editing the source code of the module revealed that all the blame "workaround for brightness stepping quirk". It is activated on my system, but if it is commented out everything starts to work as needed. I offer the option to enter the kernel boot command line, which would be forced to cut off this vorkarud or correct the error. Sorry for my bad English. -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
