Unable to control display Fedora 20
Hi I resonantly installed Fedora 20 on my lap top ProBook 4540s. I am unable to control the display brightness among other issues that I am trying to figure out how to fix :(
Under /sys/class/backlight/ there is acpi_video0 and intel_backlight. If I use the keyboard shortcuts it goes and edit /sys/class/backlight/acpi_video0/brightness rather then /sys/class/backlight/intel_backlight/brightness causing it to have no effect on the backlight. But from the command prompt if I do echo 1500 > /sys/class/backlight/intel_backlight/brightness and it works How would I go about fixing this, the file /etc/X11/xorg.conf has 0 bytes and if I try to regenerate this by issuing Xorg :2 -configure I end up with below error X.Org X Server 1.14.4 Release Date: 2013-10-31 X Protocol Version 11, Revision 0 Build Operating System: 3.14.3-200.fc20.x86_64 Current Operating System: Linux localhost.localdomain 3.15.10-201.fc20.x86_64 #1 SMP Wed Aug 27 21:10:06 UTC 2014 x86_64 Kernel command line: BOOT_IMAGE=/vmlinuz-3.15.10-201.fc20.x86_64 root=UUID=80a24ce6-901b-4691-8163-b67b9fd59132 ro vconsole.font=latarcyrheb-sun16 rhgb quiet LANG=en_GB.UTF-8 Build Date: 27 June 2014 01:35:28AM Build ID: xorg-x11-server 1.14.4-11.fc20 Current version of pixman: 0.30.0 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

There's probably a "right" way to do this, but personally I would just create a script that increments the values, and another that decrements, and then create custom key shortcuts to those scripts. Something like this:

Hi NotKlaatu, thanks for the reply, but it just took care of its own, I ran an update resonantly for some other issue that I was having. Only thing is drivers are not updated (still the same driver is been used) any how it is working
Thing is I dont know what was the fix! (if I ever had to reinstal my lap) :( Thanks and best Regards |
