Red Hat Bugzilla – Bug 416431
Updating to FC8 setting brightness with FN-.. on X20 laptop doesn´t work anymore
Last modified: 2018-04-11 03:58:45 EDT
Updating from FC7 to F8 in the last days, running the Xserver I can´t change the
display brightness for the X20 laptop with FC-"up" and FN-"down". The icon is
shown in the left-up corner, but it´s not possible to change the setting. This
works on the console, but not any more under X.
Using radeon driver with internal M24 X600 ATi card.
No logs in kernel-ring-buffer, messages or Xorg.log for this problem.
