View Full Version : Problem with brightness settings on notebook Ubuntu 13.04 -> 13.10

October 19th, 2013, 11:28 AM
Hello. When I had Ubuntu 13.04 I could change my brightness settings because I had this setting: "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"". After update this stopped working. Only if I add GRUB_CMDLINE_LINUX="acpi_osi=Linux" I can control it but it doesn't show me the bar and I can't have absolutely minimum brightness. Any help? Thanks in advance.
