Dell XPS 15 l502x mini-Display Port stopped working after update.

After the updates on the 11-10-2014 my mini-display port (which worked great previously and is part of the Intel Graphics) stopped working.
Am running Arch 64bit with Slim + E19
The symptoms are:
1. Detects monitor from the laptop and xrandr throws no errors
2. Enlightenment thinks the screen is connected and it appears in the screen setup as on.
3. The monitor no longer recognizes that there is a laptop plugged in and just stays off...

As far as I can see my options are to try and roll back via pacman -U in my /var/cache... or to figure out how to make my Nvidia HDMI output work using Synergy...
I suspect this is some type of driver regression (kernel/mesa/xorg) but am not sure as I have not seen much information about this issue online.
Unless someone has a better idea... when I get time to try to resolve the issue I will update this post.
Ok I missed this from dmesg:

So I downgraded those packages and the kernel with no luck.
I tried to get the HDMI working via Synergy... and failed
I then tested the Display Port on Windows and it did not work there either - exhibiting the same symptoms as Linux - the OS sees the monitor but no data was transferred.
So I ended up using one of my Display Link monitors at work... the USB monitors were ok, just an irritation with a flickering mouse.
I hope it is the miniDP>HDMI adapter and not the port... very frustrated by this problem.
I hope to test another adapter soon.
I think as nobody else is experiencing this issue that it may well be hardware/firmware related.
Hope there is a happy end to this post but not feeling so positive right now.

Wifi iPad 3 charger stopped working after updating to iOS 6, help!

Wifi iPad 3 charger stopped working after updating to iOS 6. The little iPhone charger charges it very very slowly, but the charger gets really hot after a while. I restored it and everything works but the charger. It's only a few months old, should I try a new iPad wall charger block?

Hi,
I did this after reading the forums and it made no difference. it has actually charged from 14% to 67% but thats taken over 12 hours.
Will monitor it and if no joy will go to a apple store
Thanks

Earpiece stopped working after updating to 5.0.1.

It worked fine the night before. Then it stopped working after updating to 5.0.1. I can only hear calls on speaker. Did anyone else have this problem. I have tried all the fixes, restart, reboot, restore. No debris in the headphone jack, and when volume is turned up or down it doesn't show headphones on the screen. Nothing covering the earpiece. Tried to blow out headphone jack with compressed air. I'm thinking it is a glitch in the software. Using Iphone 4 on Verizon. Any thoughts or ideas?

HT201371 Touch ID stopped working after updating to IOS 7.1.

Good morning to all,
My touch ID stopped working after updating to IOS 7.1.
It was working perfectly until the update and then it stopped recognizing my prints
I've reset the phone and deleted my fingerprints and now I can't even add a fingerprint again.
I am sure this is not a hardware problem since the phone was working perfectly before the update and it didn't fall nor anything similar.
Also the sensor is clean as well as my fingers.

Same problem... I think we all should let Apple know of this issue. http://www.apple.com/feedback/ tell them the probelm. So when they get too many complains they will surely fix it ASAP with a software update.

HDMI to Mini Display Port not working?!?!

Hi,
I use my macbook Air (latest one with mini display port) to watch movies on my TV. I use a hdmi to mini display port adapter cable which worked perfect for about 6 months. Yesterday, I plugged my mac in and nothing appeared. I have no idea why- no settings have been changed.
As usual, the screen goes blue and then back to normal but the TV screen is plain black. In the Display settings, the 'arrangements' tab is missing where I can set mirro displays things. I tried bying a new adapter and trying this with my sister's macbook pro but it still doesnt work.
Any ideas on why this has happened & to how I can fix it?
Thanks for your help

This is probably NOT the solution you're looking for, but use a 3.5mm to 3.5mm (headphone jack) cable to transmit sound. I use stereo speakers with my setup, sounds far better than the TV.

Apple Mini Display Port NOT working at resolutions over 1600X1200!

Problem:
Apple Mini Display Port does NOT work at resolutions over 1600X1200 on NON Apple Cinema Displays.
That means if you own any other brand of monitor such as NEC, Lacie, etc. you will NOT get native resolution on your 24 inch monitor as it is stuck at a maximum resolution of 1600X1200.
This story was mentioned on "Macbreak Weekly" show 4-14-2009. I have since checked with a few people and it would indeed seem to be true at this point.
I REALLY hope a solution from Apple comes soon and this is not some new policy of theirs. If so, it may be the last Mac Pro I will or can ever own. The reason is I do a lot of 3D work with C4D, Vue, Modo and Photoshop CS4 so I MUST have a monitor like the high-end ones from Lacie that have 100% color gamut and Adobe RGB. I can NOT be tied down to an Apple Cinema display due to that work. At this time, it seems this means I would only get 1600X1200 resolution on that 24 inch monitor.
Has anyone else confirmed this too and if so what the heck is Apple thinking or better still going to do about it? I LOVE my Mac Pro but if they start forcing displays on us then I won't be buying another Mac, it's just that simple.

Thanks, but I think two things may be different in that setup.
1. If I understood correctly, it's a first gen without a "Mini Display Port" and
2. It was a laptop not a Mac Pro with a video card.
I think it has specifically to do with either one or both of the above combos. In particular I think it's the video card they are putting in them.
I am not sure if a new 2009 Apple laptop with a Mini Display Port connected to a NON Apple display would have an issue or work like yours does now. It would be interesting to get to the bottom of this for sure because it REALLY hurts people like myself that are into 3D design.
I will try to get back on this once I continue to find out more details.

Mini display port not working in xp

Got windows xp partitioned onto macbook pro, and everything else works fine, but trying to use the mini display port does nothing when connected to a tv. any ideas? am I missing a driver?
I looked around and other sources say that it should see the MDP as an external monitor but the only display option I get is the graphics card itself.
please leave some advice, I really want to play some fallout on the big screen

omg nm, figured it out, went into the nvidea settings and set it up there

Mini Display Port Not Working, WHY?

When I first got my MacPro I tried to display two monitors and couldn’t as the Mac didn’t detect anything fed from the Mini Display Port.
When connecting Either my BenQ M2700HD, BenQ FP222W or My Wacom Cintiq 12wx to the MAC via the Mini Display Port none of them were detected by the MAC. However all 3 work through the DVI Port on the MACPRO itself.
I have tried 2 HDMI>MiniDisplayPort (officail apple) adapters in order to rule out the adapter itself and neither fixed the problem.
Therefore I can only guess that its the Mini Display Port’s internal connection.
Any help you can provide would be greatly appreciated.

I havent yet opened up the computer as im hoping i can solve the problem without doing so.
It's a mac pro so all it takes to get inside is to take the lid off, right? Not a big deal. But so far, for this problem, I'm not sure what you would plan to do whle "in" there.
I checked all external connections and they are all 100% secure and fully seated.
Ok.
I have notice that when i turn the 2nd monitor on/off (on the monitor itself) the 1st monitor flashes blue.
Why would it be doing this and still not detect the monitor itself?
Because a video card problem? Maybe you need a replacement. I supose it's possible for the mDPs to not wiork even though the DVI does.

Sound Out from Mini Display Port Not Working on a Particular TV

I have a Macbook Pro that I purchased new a few months ago. I use an adaptor to run the display out of the Mini Display port to an HDMI cable on my TV, sound and all. I have also used it while traveling to do the same thing on hotel TVs with HDMI ports.
When I do this, I have to go into System Prefs>Sound and specify the sound output should go to the model of TV that is displayed in the prefs. It always seemed to detect the model of TV when I have it hooked up.
I am staying in a house where I can't get the sound to go out of a Toshiba TV. It shows up in the sound prefs, but I can't ear a thing. The only way I can hear sound is if I tell it to use the internal speakers.
What am I doing wrong when it comes to the Toshiba?
Thanks.

Greetings,
But I wanna know what is the best way going ahead to get this fixed.
Thats up to you. Given the testing you have performed the only additional items I would suggest would be:
Reset the SMC and then test: http://support.apple.com/kb/HT3964
Reset the PRAM and then test: http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html
You can make an appointment with a Mac Genius at an Apple store, contact AppleCare via phone, or contact an Apple Authorized Service Provider for assistance.
Calling AppleCare and having them send you a box for the computer would be the fastest method of repair (usually) as an AppleStore or an Apple Authorized Service provider may not have the parts in stock. You could certainly take the computer in to have them look at it and tell you what the repair time frame would be.
Also, if they decide to replace the part, will I be shelling out any money inspite of the coverage ?
If you would like to read the warranty of the Macbook Pro, Hardware warranty details are found here: http://www.apple.com/legal/warranty/
The warranty covers manufacturing issues. As long as the failure is due to a hardware component failure and not outside influence then there is no out of pocket expense.
If the port has failed because a 1 year old shoved a nail in it, rain blew in the window and shorted out the logic board, SUV backed up over the computer and broke the port, then the warranty will not cover it. They will contact you and let you know that the repair is not covered and ask if you want it repaired at your own cost or you can pick up / have the computer sent back to you.
If for some reason you find out the issue is not covered then you could take it up with your insurnace company (renters / home owners etc) or your credit card company if you purchased the computer with a credit card. Some credit cards offer hardware coverage for purchases.
Best of luck.

Right USB Port stops working after disconnecting device since 10.9.2

Hi,
Since updating to 10.9.2 the right USB port on my MBA stops working after diconnecting a device (tested: external hard drive, USB flash drive, USB HSPA Modem). The only way to get the port recognizing the device on that port is to do a restart. If the device is connected from starting the MBA it works fine, if I then eject the drive and reinsert it or a different USB device the device doesn't get recognized. The devices do get power, my WD passport ultra spins up just fine, the USB HSPA modem also indicates it's working (with signal) but nothing shows up in finder or diskutility. If the modem is connected from start (and thus working) and then disconnect from the internet but not remove the drive I can reconnect to the internet. The problem only occurs after disconnecting the device. The port becomes inactive. The left USB port works as expected.
Steps I've taken:
Disk Persmission
PRAM
SMC

Nothing out of the ordinairy. Thanks for any help

It's an Apple Pro keyboard and mouse, the dongle is
plugged into the Mac and not the keyboard. The same
set-up is, and has been working on all our other
Macs.
The sleep issue sounds interesting- hum, maybe...
Is your keyboard plugged into one of the USB connections on an Apple monitor? If so, you may want to change that connection to one that is on the G5 itself. My monitor came with a warning note indicating that problems will likely occur if the keyboard is connected to the monitor.
I also had a problem with the automatic sleep function. After much trouble-shooting and a logic board replacement, it was concluded that coming out of the automatic sleep function with any USB device active would freeze the entire USB bus. After disabling automatic sleep in system preferences, I've had no freezing problems. My machine works fine with the manual sleep function in the Apple Menu.

Help, 10.6.8 update, all usb ports stop working after 10hrs

I've been running 10.5.8 for ever and finnaly tried to update to 10.6.8.. After I did it, the usb ports all kick out any connected devises after around 10 or so hours. I ran of the install disk, using disc utillty, disk repair, and repair permisions a few times and it did not help.
I did the install a few times again to try to see if it would help and didnt.
i tried an erase and install and migrated everything over from my orignal back up external drive that is running 10.5.8 and issue is still there.
My old 10.5.8 back up external drive works fine and does not have this issue, and I have been using that as my start up drive instead and working from there. But that is not really a solution and a temp work around.
Any suggestions would really help. thanks!

I have a early 2008 macbookpro 2.8 duel with silver keys.
I purchaed the 10.6 disk from the apple store. I've had the machine for years and purchased it refurbished from apple.
I did the erase and install and migrated everything over from external drive, then did update to 10.6.8 and the usb ports still would stop working after a few hours.. Then I read on another apple community forus to reset pram, and pull out the power cable, take out the battery and hold power key for 5 seconds, then restart. that seemed to fix usb issue so far..
But overall my computer seems to be running slower then when using just 10.5.8 and it did not wake from sleep once and I had to force power off and restart.. But maybe its just getting used to 10.6.8. we will see..
Also, on another note, my battery is totally dead, and I can only run computer with power cable.. Will this affect things? it never did with 10.5.8..
Oh, on my erase and install, I just did the simplest version and did not do the full erase to zero using he advanced security measures.. I just did the one where it writes on top of everything..

2010 Mini superdrive has stopped working after Mountain Lion update - anyone else?

After updating to 10.8 the superdrive on my 2010 mini has completely stopped working. It will not accept any disks. Disk Utility sees the drive as a working drive. Anyone else having this issue? If yes and you've resolved it, how??

Same thing happened to me with Mountain Lion. It seems that at the moment there's no solution. I've tried to burn a DVD with Toast Titanium, iDVD and the SimplyBurn. All of them failed.
It's a shame that Apple did this because we pay for a computer with a drive that could burn DVD discs. I´m very, very disappointed with Apple!

1 of 2 USB ports stopped working after 10.7.2 upgrade

I have the newest Macbook Pro. I upgraded to 10.7.2 today and immediately after, 1 of my 2 usb ports stopped working.   Thought it may be the cable, so I switched cables. Tried plugging in my iPhone, my portable drive and nothing.   Both work on the other port though.   Both ports worked fine before the update.
I've rebooted 4x.
Suggestions?

    Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
If this does not help, contact Apple.

Satellite R830 - USB3.0 port stop working after long time usage

Hi there,
This is my new laptop. I got it just one week. However, USB 3.0 port is very weird. It always stop working when i used it for several hours. I try to update the driver, but i still seems not working.
are there any other solutions?

>well, it will stop working as well when i use it as data transfer.
So how long does it take until the USB 3.0 port stops working?
Does it interrupt the data throughput?
Did you use the USB 3.0 compatible devices?
On the Toshiba European driver page you can find the USB 3.0 driver version 2.0.34.1.
Are u using this version?

First USB port stops working after random time and won't work until I restart

Hey guys
I have this problem on my late 2011 Macbook Pro 13 inch,
It's been for a year already and it really freaks me out and drive me crazy
My first USB port next to the thunderbolt stops working after like 3 days, and it won't respond until I restart my computer or log off and log in again.
If I restart my computer, USB stops working after 3 days and won't respond until I restart
If I log off it works for like a couple of hours and then stops again
I have tried EVERYTHING, SMC reset - no luck, PRAM reset - same results, Upgraded to lion same results, Upgraded to mountain lion - SAME RESULT
And I can't take it to an apple store because I'm not from the US
I am 100% sure this is a software problem and I've seen here that many people have faced this problem
Please help, it really freaks me out

I'm sure this isn't what you want to hear but unless you really are using your laptop 24 hours a day, is there any reason why you don't just shut it down and reboot when you're ready to use it again? I have to wonder how many other MacBook Pro owners potentially have the same problem but when they quit computing for the day, their computers quit too.
