Re: brightness

2016-09-08 Thread Go Canes 
A recent kernel update broke function keys on my wife's Dell XPS 13.
Reverting to the prior kernel worked-around the issue.  I haven't had a
chance to pursue it any further.

So try an earlier kernel.

That would be included. You want one of the akmod-nvidia* packages. 
Since it's a recent chipset, it would most likely be the "akmod-nvida"

I can run without vga=normal, but if I run without nomodeset, the graphics
never starts and I have to restart the machine.
But even without vga=normal, I get the same behavior.

That would explain why you have no backlight control.  Try booting

not familiar with 'gnome thinking', but i guess volume slider is a good
a place as any to include a brightness slider.

as for filing a bug, a 'need to know' is if current version of 'xbacklight'
works with his video chipset. if laptop is old, fedora may have dropped
his chipset. if 'new out of box', current drivers may not work.

Patrick needs to run 'lspci|grep vga' to find his chipset and post it to
see if others with 'xbacklight' working have same chipset.

failing that, joining developers list would get faster reaction than
filing a bug report.

A gui interface would be helpful.

There should be backlight adjustment keys on your keyboard.  If those 
don't work, then file a kernel bug.  In Gnome, if you open the menu in 
the top-right corner, there should be a brightness slider under the 
volume slider.  Again, if that doesn't work, it's most likely a kernel bug.


If you open a terminal and look in /sys/class/backlight, each directory 
there represents a kernel backlight control interface.  Inside, you can 
write a number to "brightness" in the range 0 to "max_brightness" and it 
should change.  Be careful writing something very low because you might 
not be able to see to turn it back up.

gnome seems to be the 'norm' for fedora users. ;=)


any who, after posting, some thoughts which may relate:

  video chipset
  laptop make
  laptop age
  fedora version, release
  gnome packages updated

all relate as to 'xbacklight' working with your system.


do you have settings that relate to power management or screen control?


ran a quick search for xbacklight with more hits than i care to read threw.

  https://www.ixquick.com/do/search?q=%22xbacklight%22lui=english

most were related to ubuntu, and plenty were fedora.

===>

using centos here, so this may not help. then again, if you are using
kde, it might.

on my laptop, there is a battery state indicator. when i left click it,
a drop down 'power management' window contains a screen brightness
control.

this icon is enabled in 'panel bar' via;

 right click panel bar > panel options > add widgets

a window appears with 'battery monitor' icon. click to high light,
click 'star', click 'add widget' at bottom of window.


*also*, do not know if this is related, via;

  system settings > advanced > power management >

  edit profiles > [any of the profiles] > screen

below 'screen' is level slide bar, below it;

  [ ]  enable display power management

this i selected, may or may not be related to 'panel bar'.


hth.

xbacklight should work, if not, there's a bug somewhere (I'd encourage you 
to report it).

some (all??) desktop environments have a brightness applet that can be
added to one of the panels. I know that Mate has it, at least.
