Ubuntu :: Controlling Bluetooth Control Light
Dec 17, 2010
I've just bought a MSI Wind U250 netbook and installed Ubuntu 10.10 64 bit. (Almost everything is working great out of the box. There are some little problems like dead keyboard shortcut Fn + F3 which sould be killing touchpad. BTW any package or other way to configure Fn keys?)This model of netbook has a bluetooth as an option. My netbook hasn't BT, but has bluetooth control light anyway, which isn't used at all. Such a waste, I've paid for this control light after all...
I'm using GNUbiff as an e-mail notifier. It can run a command when a new e-mail comes. Now I'm using this to play a sound: play /usr/share/sounds/purple/receive.wav. But I would like to send this way a signal to the BT control light to light or, even better, start blinking in specified manner. (Scroll Lock control light would be also great)Is there such possibility? Maybe you are aware of existence of a package able to do this, because I'm unable to locate such one.I think this is really obvious adaptation for control light and don't think I'm the first one who want such function. Some laptops even has a special control light just for e-mail (like my 12 years old fujitus-siemens) and there is Polish IM "EKG" (or "EKG2", don't remember) who blinks ScrLk when a new message comes, so I figured out there should be a potentiality to manage control lights.

To protect my eyes I always lower the monitor's brightness to its lowest. In some of the computers/displays I can get the desired low brightness in some others I cannot. For example in my WinXP ThinkPad R51 laptop I can make the brightness extremely low while in Ubuntu 9.04 ThinkPad R41 laptop and Apple Mac mini/23" Cinema Display I cannot get the desired lowness easily.
But in my Ubuntu 9.04 ThinkPad laptop, just as the energy saving routine has started to dim the brightness of LCD, an idea has come up. The energy saver routine was apparently lowering the fluorescent light's power, I'm sure of it. So I wonder now if there's a way to control and set that by myself? I'd like to set the fluorescent light's power to a much lower level.

I'm using a Hama Voiis bluetooth audio device connected to my stereo. Both my girlfriend (running 9.10) and me (10.4) can pair with, connect to and stream audio from whatever application we use to the device. However to do so requires a couple of manual steps which I'd like to optimise.
First it's necessary to manually connect to device, since we both want to stream to this, connecting manually seems the best since I suppose only one can connect at any one time. Once connected it's necessary to select "Output" in "Sound Preferences" in order to use the keyboard or multimedia keys to change the volume. This latter step is a little annoying since it has to be done every time we connect. Does anyone have a solution that automatically makes this change when connecting?

i have a bluetooth modem (BlueSMiRF) that is connected to Arduino Duemilanove. I am trying to see serial communication messages from the bluetooth modem.
I have Blueman Device Manager that enabled SPP (Serial Port) and it says :
Code:
Serial port connected to /dev/rfcomm0
How do I see the serial communication on this?
I tried on console
Code:
$rfcomm listen 0
but it's stuck at

Waiting for connection on Channel 1
Is there any other way to listen (and also send) to serial comm msgs on bluetooth?

The bluetooth manager does not detect a bluetooth dongle .trying to use ndiswrapper to fix.I installed device manager and the results are shown below.i downloaded the windows driver suite. It has 4 .exe self extracting driver archives and a setupconfig.ini. The .ini file is below.I was able to extract one of the 32bit archives on a windows machine and it had about 8 .inf files that are titled weird and would not install properly using ndiswrapper probably because im using the 64-bit architecture. there are 2 64bit .exe's in the driver download, but how can i extract them in ubuntu and do i really need to install all 8 .inf files. also do i actually need to make a .inf file? if so how?

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 just recently did a clean install of 10.10. My controller works fine for games no issues there. I haven't done any sort of configuring in order to make my Logitech cordless rubmble pad 2 controller work as a mouse yet it is. It just started this morning when I booted up. I have found many threads on how to make your controller/joystick work as a mouse. But I have yet to find one on how to get it to quit doing so. Or at least how to toggle it on and off which would be better in my case as Ive found in the past 30 min that I like scrolling with the analog stick much better than pgup/dn or the mouse wheel. The main issue is that I have a 4/yo here that plays games all the time and he keeps opening random things when he plays. I also am looking into how to get virtual box to let windows xp detect my controller but I will post that later after I have done more research if I can't figure it out.

Gnome, 10.10 (likely not to upgrade to 11.04), HP-dv7t laptop, intel i7 processor.In my ongoing attempt to create a completely mouseless computing experience (and hopefully, one where I never have to leave the home row) I am currently trying to find a way to control the onscreen cursor with my keyboard.
I have found various solutions, but most of them have problems. The accessibility feature that comes with Ubuntu is (for some reason) not installed on my computer and I can't find the package, but other people who have tried the same thing have said that it is not worth the effort anyway, given that it has nonexistent customization.
This shift-numlock function doesn't work at all. Got info from this thread: ubuntuforums.org/showthread.php?t=926105. Gizmod is incredibly complex and doesn't seem to work all that well with my 64 bit hardware. I worked with it for a few hours. But, anyway, do you have any advice that has not already been posted in the other thread?

I have a Compaq Presario R4000 running Ubuntu Linux 9.10 karmic. The system runs very hot and one of the fans is wither never running or always running at the slowest speed. For a while I thought the fan was dead but I just updated the BIOS (Phoenix BIOS) and during the update, that fan suddenly kicked in at full speed! How can I get that fan to spin up during normal usage? I have tried sensors-detect but all it found was k8temp, no fans... (SpeedFan under windows found no fans either)

I've been looking for a way to use my laptop (running Ubuntu) to help service a remote laptop (running Windows XP). I've used TeamViewer and Cisco's VPN Client before, but TeamViewer is Windows only, and I don't want to pay for a Cisco system just to help maintain my friend's computer.
Ideally, I'm looking for something similar to the programs listed above, but I really just want to know if any of you have done this before, and if so, how?

I have done a standard install of Ubuntu 10.4 Desktop. All I have changed is to edit the smb.conf to set the correct workgroup. Everything is working fine, except that I am not able to connect to Ubuntu from my Windows 7 pc using Windows' built-in tool. That should work, shouldn't it? Do I need to edit more settings?

If so how would I do it? I always get confused when I install the second distro when it asks what to do,use / or boot as the option etc...

I have my desktop set up as a SOCKS proxy, and not only me uses it, some friends do too.What I would like to know is how to check every now and again what they are using it for... for example the agreement we have is that they only use it to watch BBC iplayer and 4OD etc while they are abroad. What I dont want is them to pointlessly use it for other browsing.I trust my friends wont, but is there also a way of checking they arent using my connection to download illegal torrents?I guess best case scenrio would be to be able to whitelist only a few sites per user request. Is this possible?

So, I have an ubuntu box (no keyboard/mouse), connected to a 1920x1080 TV on my wall which is usually used as a media center. Some times I want to do some maintenance work through the GUI so the obvious thing to do is have some kind of remote administration software like VNC. That is generally very laggy and I don't need a full remote administration because I already have a big TV in front of me, I just need to use my laptop's mouse and keyboard to control the linux box.

I don't know how this happened, but my keyboard copy and paste functions have stopped working. Oddly enough, I discovered that I can only copy and paste by using the third mouse button. Pressing down on the scroll wheel after highlighting text copies the text, pressing it again pastes it Ican still use the Edit-copy and Edit-paste menu functions.
I'm sure it has something to do with all the tinkering I have been doing with my desktop. I have been experimenting with CompizConfig and Cairo dock, changing my themes and things of this nature.

I'm looking into upgrading my laptop from 9.10 to 10.04, but before I do I wanted to find out if I can limit the number of packages the system must install for this purpose. I began the process to upgrade, and the wizard informed me that on top of package upgrades, 288 packages needed to be downloaded, for a total well over 1GB of downloading. While my internet connection can support this, I don't feel the need to install 288 packages, most of which I'm certain I will not be using, nor will most of these be dependencies for things I do use.
In short: can I pick and choose what gets downloaded and installed in the upgrade? I've asked this question before, and somebody said the answer was 'yes', however I see nowhere to control this. No buttons, no config files.

I am running Ubuntu 9.10 Karmic Koala, and I am having problems with GDB. When I attempt to debug a C program in kdbg or codeblocks, the output terminal will display this message: "warning: GDB: Failed to set controlling terminal: Operation not permitted" I have searched quite a bit and I have not found a fix that works.
I am running the latest stable versions of all my software supplied by the ubuntu repositories My system meets all the dependencies for KDBG and Codeblocks
I am running gnome, but the KDE files installed by Synaptic are version 3.5.10
I have KDBG version 2.1.1
I have GDB version 7.0-0ubuntu1
I have CodeBlocks 8.02-0ubuntu4
If anybody needs any more information in order to give ideas or knowledge on how to fix this just let me know

I use Apache 2.0.55 (Ubuntu) as a document server for a business association. When the document files expire, I change the permissions so that only the owner can open them but I like to leave them on the server so that they are all in one place.
Here is my trouble--when visitors come to the site and get the directory listing, all the document files show up, whether the visitor can access them or not.
Is there some way to configure the server to not show the inaccessible files?
I guess a few technical details might help. During their useful lives, the files permissions are set to 644. Once they expire, I change them to 600. After the change, the files are still visible. Setting them to 000 doesn't help either.
It might be of note, but directories behave differently than files. If I set a directory to 600, it disappears from the listing.
