i have a desktop computer with a fresh install of ubuntu 9.1. the display is too dark to see pictures and several websites as well. is there a gui tool for color and brightness correction, or do i need to do something special?
View 9 RepliesUbuntu, in its most recent version (9.10) has stopped to support certain webcams that it previously supported with just plug-and-play simplicity. After many searches on the web, I could somehow managed to make my old webcam (Logitech QuickCam Traveler) work. Skype couldn't see it, but adding the command bash -c 'export LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so; skype' to the launcher, worked the miracle.
Whatever, the image was very dark, and in a new web search I found a solution [url] As stated there, I opened the Terminal and entered:
Code:
All is OK, brightness gets up, I can finally see my face (not a great view, but I somehow got away with it) in Skype's test, but I need that change to be PERMANENT, so every time my parents open Skype (it's my parents' computer) they won't have to mess with Terminal (they're 69 and 72 years old, it's their first computer, so I CAN NOT expect them to use Terminal, they just want to open Skype and use it, as they did when they used Windows (until two weeks ago, when I finally convinced them to switch).
I have a ViewSonic V1912Wb-4-- It recently got broken. I got to it repaired. However I cant force the brightness or the contrast of the monitor to increase or decrease, it is just stuck!
In my WinXP I can adjust this with software-- however I cant change anything on my slackware 12.2!
Do you think I need to install softwares like Argyll CMS?
I am using the default graphics drivers. I cant find anything for my built in graphics card of my Asus motherboard P5S-MX SE.
EDIT: I finally figured out how to do it - xbacklight -dec 10 lowers, xbacklight +inc 10 increaces. I'll use ubuntu tweak to get the shortcuts. I got my self a new lappy, and Acer Aspire One 751h-1948. After that, I installed Ubuntu Karmic on that, while leaving a 20GB XP partition. I configured it's Intel GMA500 Poulsbo video card, so now I can use it at the native 1366x768 res. Most of my fn keys work, other than one very important one, and here lies my problem; The brightness keys dont work(fn+left/right arrow). I've searched the net for a long time, but I still can't find a solution that works with karmic - perhaps i should downgrade?

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?
View 5 Replies View RelatedAfter updating to 9.10 NBR on my MSI U90 it behaves like pressing the function keys "increase brightness" and "decrease brightness" continuously, including show the appropriate pop up.
I guess it is related to power management because it mainly happens while on battery.
How can I get rid of this problem?
I am running Karmic (9.10) on my macbook air (2,1) and although many things work fine (I wrote about it here:[URL]) one of the last things that doesn't work is setting the screen brightness. The FN-F11/F12 combo does bring up the brightness adjustment notification window (top right) and I can change the setting, but it has no effect UNTILL I reboot or suspend to RAM and reboot.
A related issue is that the brightness doesn't automatically adjust to the surrounding brightness.
After manually setting the display brightness on my laptop, the system re-sets the value. If the laptop is plugged in, the value is set to full brightness; if it is not plugged in, it is set to dimmer. How do I stop that behavior?
Note that I am not talking about what it does in response to the event of plugging in or unplugging my system. It changes on it's own - usually several minutes after I change the brightness value. I have observed this behavior on different systems, different distributions, and different desktop environments.
Today I installed debian-8.1.0-amd64 on my older Samsung Laptop (Model r560). The installation without a desktop environment worked fine and the system booted without any problems into the virtual console. There was however one problem: when I was away from keyboard for some time, the screen turned black and when I came back and hit a button to wake the system up, the laptop immediately restarted. Later I installed the gnome desktop environment. This also worked fine.
But whenever I try to change the screen brightness in the gnome-shell, my system immediately restarts and successive attempts to boot debian fail. Some time later and after countless attempts to boot debian, it finally does boot again. By "debian fails to boot" i mean the following: The initial ram disk is loaded and fschk runs. Usually the system suddenly reboots at this point. SOmetimes, however, the video mode changes, the console font is changed and some services are getting started, but then at some point the system also restarts. I don't reach the point where a login prompt appears, or the graphical environment starts up.
Assuming, it has something to do with buggy acpi implementation of my hardware, I tried the following:
I tried to disable acpi completely by using the kernel parameter "acpi=off". This doesn't work and causes the kernel to hang
I tried to start debian without using a GUI using the single parameter. This also didn't work.
acpi_backlight=vendor also did not fix the problem.

View 4 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.
I'm having a really strange problem, when I turn on openSUSE, the brightness is fine.owever, as soon as I log in the brightness gets obnoxiously low. I have a MacBook Pro 7.1 with openSUSE 11.4 KDE

View 1 Replies View RelatedI am currently using Windows 7 but I would really like to install the new Ubuntu, what bothers me is that I tried using Ubuntu 9.04 few months ago and I had troubles changing the brightness (Toshiba L40). I have searched in the forum and it appears that there are quite some people with the same problems, of course fixes are offered but as at least some basic kernel knowledge is required I am in no position to follows the proposed steps. Since this is one of the determining factors whether to stay with Windows or go to Ubuntu I was wondering whether this problem is fixed in 10.04 or not?
P.S. I haven't tried messing with the kernel because I have only one laptop and I am afraid to lose the information on it.
I have a sony vaio VGN-NW270F.Everything is working fine except the FN brightness keys, they are mapped to F5 and F6. If anyone knows the solution to this problem or could provide me with a way to map different keys to control the brightness of my monitor that would be great.
View 4 Replies View RelatedI just recently installed Xubuntu 11.04 and I want to adjust the brightness levels. I tried using the corresponding buttons on my laptop, but they aren't working. Where can I find the brightness settings on the OS?
I tried this thread: [URL] , but "Power Manager" didn't have that setting.
I want to pick up an obviously unsolved problem. I have a Samsung Q210 Seven Notebook and recently installed Kubuntu. Everything works fine, as long as I put on my sunglasses when working with the notebook in the evening. Triggering the hotkeys shows an icon with a percentage counter that increases or decreases, depending on which function key I use. Although this looks really nifty, it gets boring after utilizing a few times. And, as you might already think, the brightness doesn't change here...
I found a hint telling to adjust the /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor"
The only effect this has is that the nice percentage lowering/raising minigame doesn't work anymore
Also, nothing from the suggestions from the previous post work. This is really bad, since that way not only the user's eyes suffer, but also the energy consumption of the display is maximized.
how I can change brightness/backlight intensity
I am using GeForce 7600 GSNot using the Nvidia X driver message you know... I searched all over, and seen this problem on many searches but no resolve issues.I want to be able to connect my tv, I use to be able to when I first installed Ubuntu and now IdK.
View 3 Replies View RelatedI took the courage yesterday to install ubuntu 9.10. Internet was working absolutely fine (wireless), but brightness controls were not working (they still don't). So I went to this page https://wiki.ubuntu.co/Hotkeys/Troubleshooting, and ran following command(s) killall gnome-settings-daemon gnome-power-manager Now since then I cant get the internet working, and cant see the wifi connection on task bar. I have restarted the laptop but no avail.
PS: any help on how I can reduce the brightness of monitor. I am using SONY VIAO VGN FZ38M, with Nvidia 8400M GT. I have tried several threads and tried all sorts of things, like xbacklight, or somthing to do with sudo .VGA/LCD/brightness.etc.
I cannot adjust the screen brightness in the power management menu. I can access the window and move the scroll bar, but there is no change.
I am on v 10.04 32bit , a Benq joybook s35.
It was working just fine on the previous version of ubuntu.
I have a fairly new Samsung 2233RZ 120hz lcd hooked up to a GeForce 8800gt...
When i click on the Brightness and Contrast controls on the monitor it gives me "Not available"...
Does the linux nvidia drivers disable my monitor functions? is my monitor improperly configured? do i need to take some steps in setting up my monitor? there are some tiny white scanlines going through the display horizontally if i look real close...minimimalist ubuntu 10.04/XFCE4 same happend on ubuntu 10.04 gnome... with or without the geforce drivers.
Problem with lowering brightness and increasing it, When I press button to lower brightness it doesn't remember, but when I set it with power management it is fine.
View 3 Replies View RelatedIt seems that the brightness applet of Maverick has some bugs. I can adjust the brightness of my laptop using the Fn keys, but the notification bubble does not appear. (You know, the one that appears at the upper right hand corner of the screen when you get notifications.) Also tried adding the brightness applet to a panel, but does nothing when I try to fiddle with the slider. And one more thing, when I unplug my laptop from the power adapter, it doesn't scale down the brightness automatically, the same way when I plug it back in, the brightness doesn't scale up.

I Add the repository to the sources list and enable it
sudo add-apt-repository ppa:voria/ppa
Perform complete system update
sudo apt-get update && sudo apt-get upgrade
it may take long time depending the internet connection
than I installed packages "samsung-backlight" and "easy-slow-down-manager"
sudo apt-get install samsung-backlight easy-slow-down-manager
Also I made changes in brightness setting in during the boot i.e set to user control instead of automatic. But after doing all these stuff still my laptop brightness not control by fn + up/down keys.
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?
