[Solved] Brightness control does not work in xfce4 moreover.

Hi everyone.
I installed Arch on my HP EliteBook 8460p laptop and have a good time with it.
However after a hang of xfce (the mouse was still working but the screen hang), I cannot control my brightness by Fn+F10 anymore.
The brightness progress bar pop up but it doesn't change when I press buttons so now I have to work around with commandline but it's so unconvenient.
Any advice? I looked for errors in many xfce config files, change brightness value (I restored it after that) but nothing seem to work. Thanks for your replys.

Have you tried some kernel parameters?
https://wiki.archlinux.org/index.php/Ba … ne_options
I have lost function-key backlight control after a kernel upgrade and had to add one to regain it.
Alternatively just use a keybinding for whatever command you are using (xbacklight?).

    Julien-
    I have the Apple MC184LL/A Bluetooth Wireless Keyboard.  The brigtness control works with mine, as do most of the other functions.
    Try cycling the keyboard off and on.  Hold the power button until the green LED goes out.  Then press it one more time to turn it back on.
    You might try resetting the iPad's network.  Go to Settings-General-Reset-Reset Network Settings.  Then you may need to reconnect your WiFi and Bluetooth.
    If that doesn't help, try resetting/rebooting the iPad.  Hold both the Home and Sleep buttons for several seconds until the Apple logo appears.  Ignore the "Slide to power off" arrow.  The iPad will restart in a couple of minutes.  Resetting this way will not hurt anything, and sometimes clears up mysterious problems.

  • Keyboard volume control does not work

    I have an iMac G5, running OS 10.5.8, and a new Apple Keyboard with Numeric Keypad. My keyboard volume control does not work. Any have ideas as to why ? (I have a similar set-up at work with no volume problems.)

    Try system prefs/keyboard/keyboard/ and uncheck Use all F1, F2 etc as standard function keys.
    Other wise the volume and brightness controls will only work if you hold down the function key first (fn)

  • My Bose SIE2i volume control does not work. (pause/play does work). This is the secone set - the apple store in Sydney replaced the firsat set that had the same problem. It was working OK and has stopped.

    Thanks again V.K. I did check the layout, and it was listed as alphabet when I inputted the password. So that doesn't seems to the the issue.
    Just finished a truly mystifying experiment, but I put in a shorter password in the way mentioned earlier and it worked. I then systematically kept increasing the characters of that password and it seems that if the password starts to exceed about 16, it stops recognizing it. I am fairly sure it is not the password itself since it never gives an error when typing in the verification password. So unless I systematically make the exact mistake twice at the setup screen, and then don't or make a different mistake every time at the login screen, I don't think its my typing skill.
    So problem solved for now, but I am still a bit worried. Maybe I should completely reinstall and use a shorter password.
    Is there supposed to be a length limit?

  • Mission Control does not work!!!!!!!!

    Hi all,
    I have recently Reformatted my mac and made it into 1 partition of 500gb just to run mac os x. I did it with the discs the laptop came with.
    After OSx install was complete, I ran the os x lion downloaded from the app store and installed it too. After completely updating the system with software updates and my other software like ms office, vlc, flash, iLife etc.
    I have found that the mission control does not work sometimes. It allows you to swipe from screen to screen but when when you swipe up.. It hides the top apple bar but nothing else happens.. Everything else is fine so far.
    When I turn my mac on. If it gets stuck the only way to make it work again is to restart. Which is a bit annoying.. Plz tell me if it's a bug or something.
    If that happens to someone else as well?
    Thanks

    Does it work ok if you create a new user?
    To create a user account:
    Choose Apple menu > System Preferences and click Users & Groups. Click the lock icon to unlock it, and type an administrator name and password.
    Click the Add button below the list of accounts, choosing a type of account Standard is fine) from the New Account pop-up menu.

  • [Solved]Brightness control doesn`t work anymore

    Hi!
    I`ve made my 3rd update of Arch since installation, and... where previous two succeeded, the third one failed. It messed up my system
    The problem is, i cannot change brightness any more through my function keys (and since i`m using Openbox as my DE, i cannot change it at all ). The brightness now is so low that i can barely see what i am typing. And it is not only in my Arch, it also messed up Windows and everything else: grub, bootup screen where i can select bios properties - everything.  I ran xev and now i see that FN+Right/Left are not detected anymore as brightness keys. It says:
    FocusOut event, serial 32, synthetic NO, window 0x3200001,
    mode NotifyGrab, detail NotifyAncestor
    FocusIn event, serial 32, synthetic NO, window 0x3200001,
    mode NotifyUngrab, detail NotifyAncestor
    KeymapNotify event, serial 32, synthetic NO, window 0x0,
    keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
    0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
    However, FN + Win + Right/Left are now detected as brightness control function keys
    KeyRelease event, serial 35, synthetic NO, window 0x3200001,
    root 0x13c, subw 0x0, time 521221, (348,-43), root:(1219,884),
    state 0x40, keycode 233 (keysym 0x1008ff02, XF86MonBrightnessUp), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False
    But pressing them doesn`t work either. I thought that it was xfce4-power-manager problem, but changing to gnome-power-manager didn`t help either.During the update pacman also upgraded kernel to latest version.
    Any ideas?
    P.S. My notebook is Acer Aspire 7720g with Nvidia 8600M GT. I tried solutions from this topic: http://bbs.archlinux.org/viewtopic.php?id=73889 but none worked for me... The problem is that the system is completely unusable at this point, since i barely see anything on the monitor, and that sucks

    I can't see what you did in Arch affecting your windows installation at all.  If you try to boot into windows and increase the brightness (since most laptops store the brightness level of the laptop as it was set, on battery, at least my 2 laptops do), does the new brightness level "stick" for all things?  If so, the only issue you have is to re-map the function keys properly, and to configure a script or something to increase/decrease lcd brightness.  You can make a simple script that echoes a value into your /proc/acpi/video/LCD/brightness file (the file path will vary, so it may be under UVGA or so).  If, however, it doesn't increase again, it may very well be a hardware issue, and not a software (since, as I said above, it's highly unlikely that an Arch update has affected Windows in any way).

  • Keyboard: audio and Brightness control keys not working with or without fn

    The Keys for controling Audio and Brightness (F1-F5) do not work.
    Also combined with pressing the "fn" key the keys do not work.
    So i only control audio with the remote control or the slider in the menubar.
    Making a reboot with deleting pram didn't help.
    I'm running the up to date version of leopard on a macbook pro (core2duo).
    I also searched in the forum for this problem.
    I oten read about "sytem control"-"keyboard and mouse"-"keyboard" and the F1, F2, etc. to use as...
    but switching this button on or off doesn't change anything.

    problem solved:
    the couse was the software update 1.1 for macbook pro, because there i had the problem like in this thread: http://discussions.apple.com/thread.jspa?messageID=6142512&#6142512
    and did the solution like that, but there i maybe made some mistakes with renaming and copying, so i rinstalled the update and renamed it a copied to plugins, and now all works as it should.
    thanks for help

  • Volume & Brightness Controls do not work on Keyboard

    I have a five and a half year old Mac (purchased January 2009) running OS X 10.5.8.  My keyboard recently became faulty, so I went to the Apple store and bought the exact same thing as a replacement.  The keys all appeared to work fine and I was very happy.  However, today I tried to play a song from my iTunes library and noticed the volume up and down keys did not work!  I then tried all of the keys across the top and discovered that the brightness keys that are identifiable do not work... that in fact the brightness up is the F15 key (when it should be the F2 key) and the brightness down is the F14 key (when it should be the F1 key).
    I have read through the forums on these boards and tried all the suggested solutions.  I have:
    1) Tried checking and unchecking the "Use all F1, F2, etc. keys as standard function keys."  Restarted the computer.  No change.  Keys still don't work.
    2) Reset the PRAM.  Did it three times.  No change.  Keys still don't work.
    3) Rebooted in Safe Mode to delete system caches.  Restarted from the Apple menu.  No change.  Keys still don't work.
    4) Someone suggested going to the Apple downloads page, but they didn't follow that suggestion up with anything else.  I see updates for keyboard software, however they are all for wireless keyboards.  My keyboard is wired, and it has the number pad on the right.
    5) Run the command "sudo killall coreaudiod" in Terminal.  No change.  Keys still don't work.
    6) Deleted the com.apple.soundpref.plist file in the Preferences folder in the User Library folder.  No change.  Keys still don't work.
    7) Checked the Audio Midi Setup in Applications to ensure that the settings for output are set to 2ch- 24 bit and 44100.0 Hz for format.  Which they are.
    I will say that something did work!  I downloaded and successfully set the function keys for volume and brightness using Spark (thanks to user turtlenecknz!).  I will use this method as I think it is the only thing that will fix my problem (for now, at least).  I'm just curious if there is a way to avoid using a software program as I'm not sure if it will need to be re-opened on system restart... for me, it boils down to reliability.
    After reading this thread - Re: Mac Aluminum keyboard VOLUME KEYS not remapping - I've determined that the original keyboard I had for this computer was the MB110LL/A model.  The Apple store gave me the MB110LL/B model.  That is why I'm having this issue.  Does Apple even carry the A Model any more?  I found the A Model on Amazon, but it's $81 + $6 shipping- yikes!  Does anyone know another site that sells it for less?
    Any other troubleshooting suggestions are greatly appreciated!  And, if anyone knows whether Apple carries the A Model any more (or know someplace I can get one cheaper than $87!), that is appreciated as well!  Thank you to anyone that read this rather lengthy message, and then takes the time to respond.

    Hello,
    Simplest would be to add Spark to your Login items to have it start each time, or in the Dock, right click & choose Open at Login.

  • Satellite C650-I5011 - Brightness control is not working

    Hi,

    Hello,
    The backlight detection depends from acpi options selection on your kernel. Which kernel version do you use ?
    $ uname -a
    (Use at least a 2.6.36 kernel since a lot of improvement for recent Toshiba laptop have been done during summer 2010)
    This done, ACPI options beeing compiled into kernel or loaded as module, this line should appear in your /var/log/Xorg.0.log :
    "found backlight control interface /sys/class/backlight/acpi_video0"
    Having a C650-15Z, my brightness control works well.
    regards,

  • MenuBar volume control does not work

    itunes volume control DOES control the volume of my external speakers which are attached to a ProSonus FireBox.
    Website links with controls of audio DO control the volume of my external speakers which are attached to a ProSonus FireBox
    However, the main Mac MenuBar sound control slide bar does not control the sound itunes or these websites AND the MenuBar sound control slide bar does not control either my internal or external speakers.
    Sound Control panel Input Panel is set at the PreSonus FireBox (0260) device with mic setttings at mid level and the master output volume set about 1.5 units up with "show volume in menu bar" box checked and Mute box clear of checkmarks.
    The Sound Control Panel Output panel is set at Presonus FireBox (0260) with the master output volume set at 1.5 units with "show show volume in menu bar" box checked and Mute box clear of checkmarks. Controlling the slider from the Sound Control Panel DOES control the slider in the Mac MenuBar but not the sound.
    The fact that sound is coming out of the firebox indicates sound from itunes and web site sound links IS being redirected from the internal speakers to the firebox and then the firebox is redirecting the sound to the external speakers.
    However, the volume control at the mac is not sending out a lower
    signal to the firebox or the firebox is not responding to the lower signal or something else has control over the volume control.
    There are two clues. The volume control of itunes DOES work and the manual control of the Firebox is working.
    Another interesting observation is that the "Sound Effects" panel of the Sound Control Panel does appear to work correctly; the alerts are supposed to work through the internal speakers (as the drop down list box is selected that way) and the Master volume does limit the alert volume. But I find it interresting that the Master volume is coupled to the internal speakers when the Master Volume should be coupled to the firebox (and then through to the external speaakers).
