General :: Unable To Adjust The Brightness Of The Netbook Screen?
Apr 19, 2010Long, sad story made short. I have a Samsung Netbook running Windows XP Home, SP3. I set it up to dual boot with Ubuntu, just so I could play around with Ubuntu. Well, Ubuntu started giving me trouble: my internet connection went south, I was unable to adjust the brightness of the Netbook screen, etc., and when I looked for troubleshooting help on the internet, it was all Greek to me as it involved working with Terminal.
I did a search for removing a partition in Windows XP and found "How to use Disk Management to configure basic disks in Windows XP" on the Microsoft and followed the instructions there.

Mar 13, 2011Running F14 on Dell Studio 14 with LCD screen and US keyboard selected. After initial power on the keyboard selection of "Windows Key" + F4 will dim the screen and the "Windows Key" + F5 will brighten the screen. When being used, either combination will also show a meter on the screen to display the adjustment of the brightness. When the lid is closed the computer is set to suspend by default. After the computer is brought back from suspend the keyboard short cuts no longer control the brightness and the meter does not appear on the screen. I have not found any other way to control the brightness and I have to restart to get the keyboard short cuts to work again.

Nov 24, 2015When I first install debian I couldn't change the screen brightness at all not manually nor with function keys, but I tried some of the solutions I found on the internet and now I can change the brightness manually (from the power management or the battery icon) but when I use the function keys it takes them like 2 to 3 minutes to respond and cause the system to hang (even mouse curser not responding) and then I'm forced to manually reboot the system, here is some information :
Code: Select all$ ls /sys/class/backlight/
acpi_video0 intel_backlight
Code: Select all$cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
[Code] .....
And I've tried this:
Code: Select allsudo -i kwrite /usr/share/X11/xorg.conf.d/20-intel.conf
And I add the following in this file
Code: Select allSection "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"

I'm using the ati driver tried running aticonfig --acpi-services off, but it made no difference. It worked fine in karmic and ibex. I'm out of ideas on how to fix this one. Can anyone point me in the right direction on what to try next?

View 2 Replies View RelatedFedora :: Adjust LCD Brightness (backlight) From Command Line?
Jul 10, 2010I'm writing a script to toggle LCD backlight on my laptop between minimum and previous/current level. I will then assign this script to a button. For this I need to be able to adjust backlight by using some command line utility. Also, this must be possible to be performed by a regular user.
What I have already tried:
1) The "xbacklight" utility. This didn't work. Program reported something like "no outputs found".
2) Used "acpitool -l <backlight_level>". This didn't work either.
3) The "echo -n 100 > /proc/acpi/video/VGA/LCD/brightness" works only when I am root. Changing permission of the file to allow writes by a user only valid until reboot. After reboot I need to change permission again, so this approach is not good either.
What works on my laptop, but with GUI:
1) Adjusting LCD brightness in "System->Preferences->Power Management" works.
2) Adjusting brightness with Gnome Brightness Applet works. However, after changing brightness with applet it says "Cannot get laptop panel brightness" and shows red crossed circle icon. Even after applet shows this message, it is possible to change the backlight level. It seems like the brightness level cannot be retrieved by the applet/system, but it can be set.
I can see that it is definitely possible to adjust LCD brightness through software because of the 2 things above, but how do I allow any user to change it from command line?
So, what are my other possible choices for changing backlight from command line?

View 3 Replies View RelatedDebian Hardware :: Getting Lenny Working On Macbook / Can't Use Brightness Keys To Change Screen Brightness?
Feb 9, 2010I'd been trying to get into Linux before I bought it so I figured that I would try to get it onto my new Mac so that I could use it wherever I am. I decided to try Debian Lenny 5.0.3 a whirl after reading about all the different distros available. I've successfully installed it and I can get to it with rEFIt, and I have quite a few things working such as the video drivers and wifi. However, I've had trouble getting it to a level where it'd be usable away from home. Here are the main problems I'm worried about:
1) I installed pommed but I still can't use the brightness keys to change the screen brightness. I'm not sure if there's some other workaround for this?
2) I tried some recommended power management packages (gnome-power-manager) but it doesn't seem to be accessible or functional right now. I don't have any way to control it or get to it that is obvious to me. Is an icon or anything supposed to appear on the task bar when you install or what? Getting some sort of power management on here is important because it gets really lousy battery life otherwise.
3) Being a Macbook, there's no right-click button. Multitouch would be really nice (two-finger scrolling!) but I'd be OK with ANY way to right-click with the touchpad. I have a wireless USB keyboard/mouse combo that works at home at least . . . right out of the box too!
4) I've seen some packages called the Mactel PPA, but they are made for Ubuntu. Since Debian and Ubuntu are so similar, is there any way to make those work on Lenny? I think that if I got those to work, I could fix some of the problems above. Or do I have to install Ubuntu?
5) I just noticed that the sound doesn't seem to work yet either.

Nov 1, 2010Up through Slackware 13.0 I used xorg.conf without trouble. On Slackware 13.1 I am caught between two unacceptable alternatives. If I don't use xorg.conf at all I can't adjust the screen density between e.g., 640 x 480 and 1024 x 768 by hitting <ctl><alt>+ or <ctl<alt>- If I use the same xorg.conf that I have used for years I gain the above facility but when I go to a console session via <ctl><alt>F1 the monitor complains that it is being fed bad information. If I can't resolve this conflict I will have to retreat to Slackware 13.0.

Jul 17, 2010Suffering from the expected error in detecting my video properly when installed 11.3.Have intel 915G onboard video. Up until 11.1 Opensuse struggled with loading this correctly. in 11.1 & 11.2 all was well. A couple of minor tweaks in sax2 and it worked perfectly. Now hat sax2 has gone I'm not sure how to make these minor tweaks.
My problem is I have been forced to a screen resolution of 1024X768 VGA Following the readme file adding nomodeset at boot fixes the problem but of course forces me back to an old video driver with pretty poor performance. Is there any way I can change the screen resolution and set the correct monitor - any GUI replacement for sax2? Krandrtray will only let me set a max res of 1024x768. I need to set res to 1280x1024
