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.

Running 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.

My computer (Samsung R580 N330M)seems doesnot adjust brightness both power manager and configuration file in /proc, I tried NVIDIA setting and it works,but I think it changes the color,not LCD. is it caused by driver problems?
View 3 Replies View RelatedI'm a fairly nocturnal creature by nature, but life requires me to spend more time during the bright hours of day. I also have a visual impairment which makes it that my eyes take a very long time to adjust to darker situations. I need to be able to easily dim my screen so that using my computer doesn't keep me awake as much and doesn't prevent me from doing other stuff.
I will accept both a hotkey based solution "like on most laptop" as a timed one. My main monitor lacks simple brightness/contrast controls. f.lux doesn't suit my needs, since it only changes the screen's color temperature. I'd like the solution to work regardless of the make and model of the video card involved. Wearing sunglasses is impractical, since they make it hard to interact with objects around my computer.
When 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"
EndSection

View 9 Replies View RelatedUbuntu 10.04 lucid with gnome-power-manager installed on a HP elitebook 8530p. FN keys and desktop display applet will not adjust the display. when I first boot my display is pretty bright with either it plugged into ac or not until i either plug or unplug for the first time then the display dims some, but will not get bright again plugged or unplugged, also /proc/acpi/video/DGFX/LCD/brightness shows it set to 100% at all times it never changes. 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?

Code:
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness
Unfortunately, I don't have that on my old PC:

View 2 Replies View RelatedI'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?
I just cannot adjust the brightness. When I use Gnome bar's brightness applet or the combination of keys on my laptop,the bar moves but there is no effect. Its too bright for me, I am getting blind for real.

View 3 Replies View RelatedI'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.

View 1 Replies View Relatedi am trying to prevent Gnome from automounting my NTFS partition. Gnome uses for this package gvfs-mount. This package with other small one's is respnsible for automounting USB changeable media like USB sticks. That works fine for me. But I don't want Gnome mount my NTFS partition on my internal storage device, where Debian Squeeze is installed too. Since Squeeze Gnome works with gvfs-mount to bind smb, ftp NTFS in. For binding a whole NTFS partition I am guessing Gnome use ntfs-3g as well. But I don't know exactly. Is there any possibility to adjust Gnome to automatically mount ONLY USB devices?
