W540 - Sound and Display in Linux

Hey dear supporter/user/reader!
After calming down due to the vast loss in quality of the new Lenovo ThinkPads (2.2k€ for such a plastic toy - rly?) I started installing a Debian sid with XFCE d/e. There were a couple of problems to solve, especially this rattly one-click-fits-all clickpad needed a lot of caring and compiling. And not to forget the first two days of my odyssey trying to boot up the machine with my OCZ Vertex 2 SSD installed with any format, partition table protocol or whatever firmware loaded - which was a sobering and vain experience. I ended up taking another SSD from my studio desktop which isn't only half the size but slower, too. 2.2k€ for a machine unable to boot a regular SSD - rly? Whatever, posting my whole snaggling-list would go far beyond the scope of this thread and we all know how capitalism and "consulting" works - so let's look forward.
There are lots of problems left but some of the major ones are:
Bad sound in Linux
Bad color reproduction from the 3k display in Linux
Sound:
In Windows the sound is quite nice. I know that it's a problem of alsa/pulseaudio drivers and that the community has to create appropriate drivers first. But there's no information around by now about the capabilities of the installed sound chip to create some usable workarounds:
Is there a subwoofer built in?
Or other channels/speakers I can route some signals to?
How is this full, brilliant and wide sound achieved in Windows?
Because just using the stereo speakers at the front edge of the notebook sounds really crappy. Routing the signal through an equalizer gets back some of the highs and the "bass" and eliminates some of the bugging mids around 1.5k but it is still far from the sound experience in Windows. And it brings in some problems because I have to setup a dirty workaround via DBus to select different presets in the e/q depending on the selected output device (speakers or headphone jack) which introduces more and more problems with muted channels after plugging a headphone aso.
Display:
The colors look quite okay in Windows, in Linux it's a yellowish-green mess. Since I read about the pretty poor quality of the built-in colorimeter before I ordered this device I didn't buy it in anticipation of the tutorials about using the Windows color profiles in Linux. Unfortunatley copying the profiles from the Windows HDD (C:\WINDOWS\System32\spool\drivers\color) and loading any of them via xicc, xcalib or any other tool handling color profiles does nothing to the color reproduction of the display. I found a profile made by a helpful person somewhere on the internet (notebookcheck? Unfortunately I don't remember) which makes this display kind of usable but it's far from being correct since it introduces a greenish inking at the lower end and a rose red one in the middle of the spectrum. Additionally the overall gamma curve doesn't fit that well. But at least it draws white as white and eliminates the overall lime style of the device.
Résumé:
Maybe I'm just an idiot, too dumb to correctly copy and apply color profiles or to use alsa/pulseaudio the correct way. If so I would be very happy about anyone who would lead me in the right direction. Perhaps someone stumbled over the same problems and has some fixes or at least ideas where to look at. Perhaps someone calibrated his 3k display with a professional colorimeter and is willing to share the results.
If someone is interested in e.g. my Xorg config, the amd64 DEB package for getting a usable clickpad, the slightly working color profile or other informations I'm able to share, please let me know.
Disclaimer:
I can understand if anyone is deterred by this rant in a way that she or he avoids to talk to such a poor goof, but perhaps someone understands my vast disappointment after spending a huge amount of money and a lot of time for a brand which is (was?) well known under (Linux-) enthusiasts for the outstanding build quality, the overwhelming compatibility and the ubergood hardware which was built into ThinkPad machines in the past. I owned, sold, recommended and installed lots of these notebooks before, my own last two machines were two t61p which I would call the peak in quality of this brand. But those times definetly seem to be over.
Thankful for every hint to make this thing more usable, best, Markus.

Here's another profile I stumbled upon. It was made for the T540p shipped with the same display. It is a little more even, so less different colours in the overall grayscale and it has a better gamma curve. But it has an overall greenish touch just like the display without any profile but considerably less.

And to prevent users from searching I upped the profile from my last post to my blog, too:
http://mein-neues-blog.de/files/LEN40B5.icm
BTW I'm actually hacking a GTK application for manipulating the ramps of a LUT profile in realtime since those profiles are not that bad but need a little tweaking to fit my own display.

X120e Sound and Display question...

Hey, I'm enjoying my x120e that I purchased earlier this year. I still love my T61 I purchased in 2008.
Couple of things though: the sound and screen.
Sound - does anyone else have hiccups with the sound where it makes a sort of long buzz through any playback for a time? If not, I need to mail in for servicing (unless I need to do a clean install or it's something I can fix).
The display is garish, and ultrabright. Has anyone had success with switching the panel to something else?
Thanks,
Erin

If the buzzing sound only happens after resuming from sleep, there was a bios update for it long time ago. Make sure you update to the latest BIOS.
As for the screen, yeah it's pretty bad for the viewing angles, there are several panels that are being used but I dont think you could request one specific part # to be replaced. I think It was a Samsung panel that was reported to be better than the LG. I had one with LG, and it was pretty crappy if not looking straight at it.

Want to measure sound and display in graph

Hi guys,
I wish to measure sound that different equipments make and at the frequencies they make the sound. I am using a micro-phone connected to A/D board. I think the harware i m using is correct. But can someone tell m which vi shall i use to make my program work ?
For Latest TECH News check out my blog at http://directfromdigg.blogspot.com

Yes;
Go back to the examples and look up signal analysis or FFT. There will be examples showing spectral analysis, combine that functionality with the DAQ you have now and you're done.

Why does iMessage continue to make sounds and display banners on my Macbook Pro (Retina) even though I have removed it from my notification center?

I hate that my messages pop up while I'm watching Netflix, and I have finally removed Messages from my notification center. Yet, for some reason i still keep hearing the noise that lets me know I have a message, and I a still seeing badges pop up on my screen every time a new message comes in? What's the deal?

I talked to Apple Support and we at least stopped the bleeding, a little bit. These are the troubleshooting steps I did before I contacted Apple Support:
1. Reinstalled OSX
2. Restore the last known good Time Machine Backup.
This did not fix my issue, so I called Apple Support and they told me this:
1. Turn Power off.
2. Wait 15 seconds.
3. Plug in Magsafe adapter.
4. Wait 15 seconds.
5. Hold down the Shift+Option+Power Button for 20-30 seconds.
6. Turn Power back on.
Ok, this stopped the bleeding a little, but as soon as I plugged in a Apple USB Superdrive
and a Apple Mini Displayport to VGA Adapter. This "USB Devices Disabled" pop-up pops up like every 30 minutes now. At least, it is not constantly popping up after I close it, so I guess it will do for the temporary. Going to contact Apple support, later, though to see what else can be done.

HT1320 If an ipod is disconnected from the USB cord without being ejected first how do you fix this matter? It's making a weird sound and displaying the Apple support email address only.

What to you do it your ipod is disconnected from the USB cord without being ejected first?

3) If this is a counterfeit, is there someone in Apple that I should contact to help them track this kind of problem?

Distorted sound and echo on airplay extended display

Since the update to Mavericks, extending the display or mirroring to my 2nd gen AppleTV, causes distorted sound and echo. Any video or music has distortion and echo. This wasn't happening with mirroring prior to the update. Anyone else having a simliar issue?

go to your appleTV and choose the auto sound setting, not the 16bit sound setting

MMacBook Pro (13-inch, Mid 2010) switches on but internal display remains off/black .There is no start-up sound and the fan starts off normal but after about Five minutes begins to run even faster

Hi ,
My MacBook Pro (13-inch, Mid 2010) switches on but internal display remains off/black .There is no start-up sound and the fan starts off normal but after about Five minutes begins to run even faster as if the machine is running a heavy load.It displayed a question mark some time back then a friend borrwed it ,he flashed the system and put windows 7.Then a few days pasted and now it wont display as stated.I have tried to Reset SMC and the Command + P + R + Power but still no response.Please assist?
Regrads Josh

I think your "friend" caused a problem (or two).
I do not know what "flashed the system" means......
Based on what was done, I would probably erase the HD and restore the system from a backup before the software changes were made.

My Mac Pro is not displaying any images for videos or games, it is showing sound and working but nothing else. DVD player is also coming up with an error.

My Mac Pro is not displaying any images for videos or games, it is showing sound and working but nothing else. DVD player is also coming up with an error. I'm not sure why neither is working, it just suddenly happened. I have done nothing different.

Lao Bo,
yes, you can locate and copy a file from your HD to a USB key using UNIX commands. If you know the exact name of the file which you’re trying to locate, try this:
find / -iname filename -print
This command will search your entire internal disk for the particular filename. If you know that it’s within a particular user account, then you can save search time with this variation:
find /Users/username -iname filename -print
Either variation of this command will print all files found which have the given filename. Presuming that you’re able to identify the correct file, you can copy it to a USB key using the command
cp -p filename_returned_by_find /Volumes/USB_volume
If you’re not sure which volume name your USB key has, this command will show you what the possibilities are:
ls /Volumes
Please let me know if you have any trouble with these commands.

Help!! Static sound and Lock ups

I recently updated to the newest Ipod Mini version software 1.4. and when i play the songs on my ipod i get static sounding sounds and when i look at the display timer, it looks like the ipod i slowing down.
Also i'm getting lockups when i'm browsing.
Ipod service told me to restore the ipod, and i have 3 times, 1 to the factory software version, and twice to the newer version. It didn't help, as i'm still hearing static sounds, and I've switched headphones and headphone jacks, and it still doesn't help.

the exact same thing happened to me. Mine is an original mini which needless to say is out of warranty, so I need an answer that is not "replace the hardware". Is there a way to restore it to a previous version of the software?

Disable sound and/or vibration while in Messages app?!

Hi!
I would like to know is there some option in the iOS where I could disable sounds and vibration while I'm using Messages app (app is open and the display is turned ON and I can see the message I recieved). This is very annoying when I'm using iMessages and getting a message every few seconds and then my phone vibrates constantly. It is of course OK if I'm not in Messages app but when I'm already using it I don't need a notification I got a message when I can see it for myself.

I'm having the exact same problem. I get a random text message ding for no discernible reason at least oncer per day. No alerts from apps, no email, no texts, no missed calls, no voicemails. It's not changing connection types between wifi, 3G, and edge. I know that the first gen iPhones sometimes dinged in that situation. If anyone knows what's causing this I would love to hear it.
Just to be clear I'm using a perfectly normal, not jailbroken, iPhone 4 running the latest software version.

HELP! Uploading AS3 Game to server, no sound and Spacebar doesn´t work HELP!

Hello, relatively new to AS3 and flash, this is the first time i am publishing anything. We are trying to upload our simple flashgame to our webserver, the game works perfectly fine locally save for one thing. We get an error regarding TLF which says it wont stream or something. So when it gets online, no sounds play and spacebar doesn't work, left and right arrow does work. We have three TLF text fields that are used to update score, lives and show you final score. If i turn these into classical text they stop working.
Things we have tried: Changing default linkage from RLS to Merged into code, changing the text boxes to classical text(they then stop working), made sure the paths are correct(all files are in the same directory including the .swz file)
This is the code from the soundclass:
package
    import flash.net.URLRequest;
    import flash.media.Sound;
    import flash.media.SoundChannel;
    import flash.events.*;
    public class MySound
        private var bgSound:Sound;
        private var fireSound:Sound;
        private var waterSound:Sound;
        private var earthSound:Sound;
        private var lightSound:Sound;
        private var soundChannel:SoundChannel;
        public function MySound()
            soundChannel = new SoundChannel();
            bgSound = new Sound();
            var req:URLRequest = new URLRequest("BackgroundSound.mp3");
            bgSound.load(req);
            //fire
            fireSound = new Sound();
            var req2:URLRequest = new URLRequest("soundFire.mp3");
            fireSound.load(req2);
            // water
            waterSound = new Sound();
            var req3:URLRequest = new URLRequest("soundWater.mp3");
            waterSound.load(req3);
            // earth
            earthSound = new Sound();
            var req4:URLRequest = new URLRequest("soundEarth.mp3");
            earthSound.load(req4);
            // light
            lightSound = new Sound();
            var req5:URLRequest = new URLRequest("soundLight.mp3");
            lightSound.load(req5);
        public function playBgSound()
            soundChannel = bgSound.play(0, 999999);
        public function stopBgSound()
            soundChannel.stop();
        public function playFireSound()
            fireSound.play();
        public function playWaterSound()
            waterSound.play();
        public function playEarthSound()
            earthSound.play();
        public function playLightSound()
            lightSound.play();
I can somewhat get that sound can bugg out, but why does spacebar stop functioning? ANy help is greatly appreciated as this has to be delivered in twelve hours(published online) for a school assignment.

Also might add publishing it locally in my own browser everything works, as does ofcourse playing it in flash itself. Changing from RLS to merged into code stops the error from coming, but doesn´t fix the problem on the server.

How to read and display a signal from my PIC Microcontroller onto Labview?

Hi,
I am doing a project on a Pulse Oximeter and i am trying to read and display the signal from my PIC Microcontroller on Labview? How do i go about doing it? I am using the PIC16F877 and also making use of the USART?
How do i implement and initialise the USART in PIC16? What are the steps to be taken, please guide me through the process? The link provides information regarding the USART connection, initialisting and stuff? Is it correct to use these codes in my program?Link: http://ww1.microchip.com/downloads/en/AppNotes/00774a.pdf
Also, i am using the RS232 serial interface to connect to the PC? The connector i am using is the DB9 Connector. Which template and VI can i use? Am i supposed to use the NI-DAQmx and VISA? Also, for my USART connection, i am using the MAX232 Driver which is applicable for my application as i am working with +5V. So far, i have been reading and trying out on Labview and the steps i have taken are:
1) Open a New VI and used the Instrument I/O(Read & Display) template?
2) How do i configure the Instrument I/O Assistant Express VI to read the info from my device connected to COM1?
3) I was reading the Labview Manual, 'Getting Started with Labview' and i was following the steps under Page 55, Communicating with an Instrument. Am i on the right track?
4) How do i check and make sure that the port settings of the I/O Assistant and my PIC Micro Match
Please help me out and guide me through the process. I am student at a polytechnic and i am very new to Labview and the software is used as a development tool for the project. I have a deadline to meet and i hope i can get a response as fast as possible. Your help will be kindly and greatly appreciated. I hope to hear from you guys soon.You can e-mail me all your answers at [email protected]
Thank You
Best regards,

Hi Ashwin,
It is a good idea to first be able to communicate with the microcontroller using some sort of serial communication software such as "HyperTerminal" or "Procomm", etc. Refer to MicroChip's recommendations on this.
Once that works, then you are ready to use LabView.
Here is a link which covers many aspects of serial communication. Link - click here
You probably received a development kit. They usually have a readily available interface. It's been a long time since I played with the PIC, but I seem to remember that you need to program the serial communication driver (as well as at least a bootloader) to get the serial communication going. The driver contains the necessary protocols so that you PC can have a machine conversation with the target (PIC).
It sounds like a fun & interesting project. Please avoid to have replies to your personal email. By having the answers posted to this thread, you will get much more support and advice.
Have fun,

How to decode and display jpeg from a bytes stream ?

Hello.
I am new to Flex and got stuck on something that I assume has an easy solution.
I have an RIA application in which I want to display a jpeg image. this image was
sent on a Web Service message, as an array of bytes (I just read the jpeg file as
is and send it to the web application).
I couldn't figure out a way to decode and display this image at the RIA, using an apropriate component. (Image ?)
I have seen a few examples where a jpg is loaded from a web server using a url in
which it's avaliable, but I don't think this is much help to me...
Your help/example apreciated.

Thanks.
I assume you mean passing the bytesArray to Image.load() ?
Anyway, that's what I did and it worked fine.
Now I am facing the same issue with playing sounds, which are available on bytesArray.
I tried to pass the mp3 bytes to the Sound.load(), but it doesn't work, becuase it tries
to cast it to a URL. do you know by any chance whether I can achieve that somehow ?
(I could use prety much any other sound format, if it makes a difference)
Thanks again.

Is there a way to check if the touch screen and display works whilst iPod is apart?

Hi,
I pulled my iPod Touch 4G apart up to the circuit board in order to pull out the headphone socket.
Before I pulled it apart, the screen was cracked but everything was perfectly visible and the touch function worked perfectly.
Because the screen was cracked, when I pulled the iPod apart, I obviously lost small chunks of the screen.
Now when I plug the two plugs from the LCD screen into the circuit board and put the iPod together without screws, it looks like this:
http://s251.photobucket.com/user/matt9210/media/2013-06-19014523_zps86e6bc6e.jpg .html
So I'm not sure whether buying a new screen is the answer, because I'm worried it will still have the same effect on the new screen.
Another question: The headphone socket wasn't working. I had to hold the earphones in order to get any sound, and knocking them would lose the sound. I checked with other earphones before opening the iPod, so it's a problem with the iPod. What do I do with the headphone socket to avoid this problem?
Also, is this good enough to replace the iPod screen? A lot cheaper than I thought, thought I'd check what the catch is.
