Debian Configuration :: Should Change Brightness Of Screen

Mar 30, 2016

I've an asuspro (more precisely the p2520la version) notebook with the fn+f5, fn+f6 buttons that should change brightness of the screen. But they don't work. For volume it's ok (fn+f11/f12), and if I go in the system settings I c an change manually the brightness (I use kde so there is a bar with which change it). But when I'm outside and the screen brightness is low I found difficult to find the menu settings and the hardware buttons would be better.I've tried adding to the kernel the "acpi_osi=" command but doesn't work.

Debian Hardware :: Getting Lenny Working On Macbook / Can't Use Brightness Keys To Change Screen Brightness?

Feb 9, 2010

I'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.

Fedora :: How To Change Screen Brightness?

Sep 18, 2009

I'm having trouble locating a way to adjust the screen brightness on fc10... It is only possible to use the monitor's control for now.Yeah my monitor make an annoying whining noise unless you turn it on 100% brightness, but that hurts my eyes.It is so crazy that they didn't put a brightness control in! ( or rather they destroyed working ones of year past, Why? )

Slackware :: Ctrl+up|down Don't Change Screen Brightness Any More

Jul 16, 2010

i had slackware 13.0 on my dell vostro 1320 and it was all good, but since the upgrade to 13.1 i cannot change the screen brightness with ctrl+up and ctrl+down keys..i'm not even sure how to start with this problem. from what i understand these keys 'call' a bios function...? so that would mean that some kernel module is not being loaded?or has the desktop environment lost the key mappings and that is causing my trouble?

Ubuntu :: Dim Screen - Cannot Change Brightness Settings On Netbook

Nov 18, 2010

I bought a Asus eeepc a few days ago which I really like, with the exception of one thing - windows 7 starter. I like Windows 7, but starter is just bad. I also really like ubuntu, so I've decided to put it on my netbook. I download the netbook edition from the site, put it on a usb drive, and than tested it out - well, my screen is dim, very dim. Changing the brightness setting on the tool bar up top doesn't change anything, and using the function keys does change it, but still keeps it very dim.

I've tried restarting my computer, same thing, I've tried messing around with settings in the battery options, nothing... I really don't want to install it if its going to be this dark, I can see things, but its not very pleasant to use. I'm starting to consider that its the problem with the file I downloaded. Theres nothing wrong with my netbook, everything worked perfectly fine in Windows 7. I use the full version of ubuntu 10.04 on my other laptop which works perfectly fine, I'm not sure why this version is acting so weird on my netbook.

General :: Bind Certain Keys To Change Screen Brightness

Jul 19, 2010

I am using Ubuntu linux, and I want fn + up key and fn + down key to change the brightness instead on fn + F4 and fn + F5. I've tried looking for something in the Keyboard Shortcuts menu, but there is no command or key specified to do that. I could make a custom key shortcut, but I can't find the command to change the brightness. Is there a way to make another key do this? My laptop is a Dell Inspiron 1545.

Ubuntu :: HP Touchsmart Tm2 - Synaptics Touchpad Is Unusable - Change The Brightness Will Kill The Screen

Dec 17, 2010

I installed Ubuntu 10.10 on my laptop and encountered several issues.

1. The Synaptics touchpad is nearly unusable. It is impossible to drag while holding down a button. The cursor will move randomly across the screen instead. It is impossible to right click; a right click is treated like a left click. Double-tapping the dot in the corner does not disable the touchpad.

2. Attempting to change the brightness will kill the screen. The computer is still functioning, and it is possible to perform tasks "blind." Only the screen becomes completely blank.

3. Ubuntu does not always boot up reliably. When it does not, the screen is blank but the computer is otherwise responding.

4. The screen is black after suspend.

5. The computer will sometimes hang when shutting down (showing desktop background). Possibly related messages in dmesg:

Debian :: Can't Adjust Screen Brightness Using Fn Keys?

Nov 24, 2015

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

Debian Hardware :: Control Screen Brightness With DDC / CI Capable Monitor

Jul 5, 2014

I bought a new computer, pretty awesome machine, AMD FX6300 with a Radeon 260X graphics. Along I bought a new Led monitor AOC with DDC/CI capability.

It is my understanding that with the DDC/CI, monitors can have their brightness controlled just like laptop screens do, but better software controlled.

This is something I have done before with nvidia graphics, the open drive had the control and the proprietary only needed a small config setting. This was done however in a dekstop iMac, the screen also LED and HDMI.

So I just freshly installed debian jessie in this setup, it seems the open source driver does a pretty good job, but still missing the brightness control and audio through HDMI doesn't work either.

Debian Multimedia :: Increasing And Decreasing Screen Brightness Crashes Minecraft

May 3, 2015

When increasing or decreasing the screen brightness, Minecraft crashes and to an extent freezes my computer UI. What I mean by to an extent is that I can move the cursor around, but I can't click on anything. I can also run keyboard shortcuts and type, which is how I restore my system by terminating all java processes with pkill.

What causes minecraft to crash and how can I solve it?

Debian Configuration :: Reboot Both The Server And The Client Machines Every Time Change The SAMBA Configuration?

Apr 5, 2010

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.

My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

Fedora Hardware :: Not Possible To Change Brightness

Jul 29, 2011

Recently, I installed Fedora 15 in my Sony VAIO Laptop Series E. Firstly, I had a little problem with nvidia drivers and wireless because I installed from a normal CD, but then I repaired it installing drivers from the web page and updating the system. However, I continue having a problem with changing brightness even with the Fn buttons or with the gnome configuration control. I followed some suggestions as for example these ones http://forums.fedoraforum.org/showthread.php?t=262545, but nothing change. I already tried with xbacklight but still not working. I also did a change in grub conf file (following google search suggestions) adding these commands: acpi_backlight=vendor acpi_osi=Linux, but nothing.

General :: Quick Way To Change Monitor Brightness At Night?

Dec 8, 2010

I'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.

Debian Configuration :: Cannot Change Locale

Jul 12, 2015

I have setup a VPS @ Strato with Linux Wheezy.Since I'am in the Netherlands I got a Dutch language package installed.I like to setup into englisch all the way.Via dpkg-reconfigure locales I have installed en_GB.UTF-8 UTF8 language packages and deïnstaled nl_NL.utf8

Generating locales (this might take a while)...
en_GB.UTF-8... done
Generation complete.

But a lot of the commands are still in Dutch like: h2458377:~# uitgelogd.And quite often I got:
-su: warning: setlocale: LC_ALL: cannot change locale (nl_NL.utf8)

How do I get ripped off this error?Just working with/on the command line

Debian Configuration :: Change Gfx Card

Sep 20, 2015

I have debian latest stable and have been using a geforce gfx card which has now failed.I have removed the gfx card and activated the on board gfx in bios and I can boot to the grub screen.The onboard gfx is on my i5 4600.After I select debian from grub I end up with a blank black screen and a small cursor in top left hand corner but I cannot type anything with this cursor. From this screen I can only ctrl+alt+del for reboot or physically turn off the pc.I think this is a driver issue but wouldnt debian just use a default gfx driver automatically in this situation so I would at least get to a console or desktop? If this is the case what is the process to enable the required driver? via rescue disk?Mobo is gigabyte GA z87 hd3 and im wondering if this might be something to do with uefi or similar?

Fedora :: Screen Brightness Resetting Itself

May 23, 2010

My issue is like this: I have a laptop (dell vostro 1400, NVidia 8400M video card) running Fedora 12 up to date. My desktop is KDE 4. I usually run the laptop connected to the power outlet, so my power profile is set to "performance". This power profile sets the screen brightness to the maximum. However, when I'm in the dark, I want to lower the screen brightness. The shortcut keys work, and the screen brightness is lowered. However, for some reason, after about 30 seconds it resets itself to the highest brightness setting. No matter how I set the brightness, it will always reset itself. Any ideas what can i do to correct this?
