Description of problem: The Brightness control doesn't work on a Lenovo G540 2949 CHU... All other fn key shortcuts work except Brightness control. How do I control the screen brightness ? Thanks Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Fn up arrow / down arrow doesn't work Expected results: Fn up arrow/down arrow should control screen brightness Additional info: I have installed the tbp and the system-config-xorg package .... but even then I am not able to control the gamma...... also I would like to be able to control the backlight brightness instead of gamma
I tried xbacklight . While I am able to control the brightness of the screen with xbacklight it jumps back to 50% in minutes. Also the fn-uparrow / fn-dnarrow (default brightness control) works when fedora is still booting in the blue screen. But it stops working when the login dialogue screen is displayed.
Please try this workaround: reboot your machine with the 'nomodeset' kernel parameter. This might be a duplicate of bug 519105 ?
Yes that solves it Thanks.
