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.

NVidia GeForce GT540
No proprietary drivers detected
Ubuntu 10.04 LTS 64bit
I 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 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.
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 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?

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.

View 4 Replies View RelatedResearching this problem, I find very often this solution:
Code:
echo -n 100 > /proc/acpi/video/VGA/LCD/brightness
Unfortunately, I don't have that on my old PC:

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"

View 9 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?
Long, 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.

The only reason I need the proprietary drivers is to use two monitors.
I am going crazy, I have tested everything I have found on the web. I have tried all the nvidia drivers version, I have tried envyng, ... but nvidia do not work!!
I am trying Xinerama with nv, but it does not work either!!!

I know i know, some will say "eww Proprietary Drivers" but hey, ubunt is all about having more control of the OS. Is there an easy way to install Proprietary Drivers thats not through the hardware drivers option on system?
View 2 Replies View RelatedI installed Xubuntu the other night (completely wiped machine) and started doing all the updates on it. After a couple of reboots, I changed from the proprietary drivers, to the regular nVidia drivers. After doing this, the startup logo is displayed at a really low resolution. Is there a simple fix to change this and use the nVidia drivers as well?

View 9 Replies View RelatedI just installed Ubuntu today and when I go to Hardware Drivers it tells me that there are no proprietary drivers on this system and doesn't show any for me to activate. Oddly enough when I was running the live CD of Ubuntu I got a list of a few drivers to activate, namely the Broadcom STA Wireless Driver and the NVIDIA Accelerated Graphics Driver (version 185).
View 9 Replies View RelatedI just built a new HTPC and decided to give Ubuntu a whirl again. I downloaded and installed 10.04, and set about configuring it. Everything looked great, except my audio over HDMI didn't work. I enabled the proprietary ATI drivers, and bam! the audio works! Great. Only one problem: there's a two inch border around my TV (not there with the open source drivers), and Boxee flashes colors rather than playing videos (a known bug. It's fixed by not using the ATI proprietary drivers). So, I disabled the drivers, rebooted, and the Boxee video works, the border/gap is gone, but once again the audio doesn't work. I've been through all the sound settings, and I have everything set to the HDMI output, but still nothing. I've tried various fixes I've found through googling

I'm experiencing video lag in games. I'm using 10.04 lts 32 bit and the latest version of proprietary drivers. For example I play hon and so and then it freezes for a small period of time which is frustrating.
I don't understand, my specs are:
Under this specs it should run perfectly. What's the matter? Ati drivers have poor support under linux? I tried updating to 10.10 and nothing. I tried contacting customer supporot amd but they can't help me. Nice isn't it?
When I run the liveCD (which I'm on right now), it shows proprietary drivers for my wireless hardware. I installed 10.04 from the liveCD onto my laptop, and after the install, it says there aren't any drivers. Is there a way I can pull the drivers from the liveCD, or should I try a reinstall?
View 1 Replies View RelatedI recently bought a new PC and it has an AMD GPU. I've been using Catalyst because the open source radeon driver gave me poor performance in games (maybe by 12.04 I can use it ).I've had some updates show up recently. This brings me to wonder if I have anything at all to worry about. This is a production machine and I don't want to muck around with fixing issues brought on by my usual apt-get upgrade.Currently, I've been avoiding updating a few packages related to the Kernel and Xorg:
Code:
The following packages have been kept back:
linux-generic linux-headers-generic linux-image-generic
The following packages will be upgraded:
linux-libc-dev xserver-xorg-video-ati xserver-xorg-video-radeon
3 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.I had an NVIDIA issue back on Ubuntu 8.04 after updating once, due to a kernel update. I had to revert to an older kernel and mess around a bit to fix my installation. I don't have any experience with Catalyst. Basically, I want input as to whether or not it's dangerous to update this sort of stuff. I don't want to mess around fixing issues caused by a rogue update
