Integrated Graphics Causing Color Show / Pink Screen

I have the weirdest issue and hope someone can shed some light on my issue has I'm baffled as to what the true issue is.A replacement motherboard was purchased foe a PC that had a motherboard issue. This is a new motherboard and not a refurbished one. Unfortunately, I keep getting a pink screen and/or a flashing colors when I use the on-board video controllers - whether VGA or HDMI. The symptoms of flashing colors and/or solid pink screen is definitely not due to the monitor has it has been tested on several different monitors and the main monitor being use to test it is the one I'm currently using and I have no issues with. In addition to the screen issues, I've lost USB controls prior to the PC lockup and screen color show. I deleted the standard VGA drivers and then had them re-installed and from their updated it and it seemed to go...

Photoshop CS6 selection, shape, and text is causing colored artifacts on screen

The Photoshop CS6 (13.0.4) selection, text, and shape tool causes colored artifacts on screen. I'm running on a retina Macbook Pro updated to the latest ML release. I have disabled GPU acceleration. I have also tried starting Photoshop with no plugins but this does not help.
I have created a video which shows the phenomena
http://www.youtube.com/watch?v=VG5ayC3WmKA

SOLVED. After two days of intense debugging I've identified the issue as an interaction between the ICC color profile, integrated GPU, and Photoshop. The ICC profile was created with an i1Display Pro using the i1Profiler software. The issue occurs when you create the color profile using the LUT setting. Creating a profile using the matrix setting seems to be ok. In summary, these are the specific conditions that cause the issue (for me):
1) Using a color profile created with the LUT setting with i1Profiler and i1Display Pro
2) Using the integrated GPU (discrete GPU is disabled in Photoshop Performance setting)
3) Running on Photoshop 13.0.4 (13.0+ all have the issue) on a 15" Macbook Pro with Retina display
Creating a new profile with the matrix setting OR enabling the discrete Nvidia GPU will also make the artifacts go away. The integrated GPU using the LUT based color profile does not seem to have any artifacts in any other photography and video editing software that I've tried so Photoshop is playing a role. The nature of the artifacts also change from Photoshop version 13.0 to 13.0.4. For example, in Photoshop 13.0 the Marquee Tool has no issues while 13.0.1+ has artifacts.

2014 Mac Mini shows pink screen when waking

I have a 2014 3Ghz i7 mac mini which I have attempted to connect two different Asus monitors via two different HDMI cables in multiple configurations. Regardless of the connection combination when the mac awakes from sleep or from the screensaver (to show the login screen) the screen shows up as bright pink and I can barely make out the password box.
Turning off the monitor and turning it back on corrects the problem as does waiting about 10 seconds for the monitor to go out of sync and return. After this time the issue goes away until the computer sleeps or I enter the sleep saver again and have to re-login.
Is anyone else encountering this?
PRAM and SMC have been reset already.

I don’t know if this solves the pink screen problem, whatever it is. I’m not a techie so this is all I can offer.
I got my Mini end of December and the pink screen problem just started now. I had no pink screen until I went to change the Sleep / Wake settings. Then I started getting the pink screen with desktop barely showing through. So think when / if you changed your settings from the default. Maybe your problem started after that.
Returning settings to default doesn't fix it. I also tried to check / uncheck different sleep / wake settings, but didn't work either.
I have the latest Mac Mini 3 GHz
Intel Core i7, 16 GB RAM Yosemite 10.10.2.
External ASUS PA248 monitor via HDMI.
I know everyone has different set-ups with slight variations in the problem, but maybe this will help some people. It seem to have worked to solve the pink from appearing, but I don’t think it has solved he actual problem. At least if I have to go to my computer every half hour, I don’t have to wear out my monitor button by having to turn it on all the time just to get rid of the pink screen.
I know people want their Mini to sleep but for these instructions your Mini will have to remain awake all the time.
This is my monitor set up.
Screen saver set to go on in 10 minutes.
Monitor shuts off in 15 minutes.
The Mini stays on all the time, no sleep or wake cycles.
1. Go to ENERGY SAVINGS
2. The only thing I have checked is, “Prevent the computer from sleeping automatically when the display is off. Leave the rest unchecked".
3. Then go to SCHEDULE Uncheck these,
START UP OR WAKE and SLEEP settings.
Hit OK
Exit ENERGY SAVINGS.
Let your monitor turn off, come back later. Sit down and re-try to to turn on your desktop. DON'T click away on your mouse or move it back and forth furiously like you want your desktop to load RIGHT NOW. Well I did that and the system didn't like that and the pink was back. It seems the system needs a few seconds to load up the desktop. Click the mouse button once, or move the mouse a a TINY bit. Wait a bit and the desktop should appear WITH NO PINK SCREEN, hopefully.
Hope this helps.

The first thing I see is the you have declared 'total' in DrawPanel. As it is never set there, you are testing a variable which is always zero.

Integrated Graphics & External Screen Problem

Hey everyone,
Seems that my late 2008 15" MBP has decided to stop working with my external screen when running on the integrated graphics card. The external screen will flash up with my desktop but then switch to to telling me there is no signal being received.
I cannot confirm if it's because I used the OS X v10.6.3 v1.1 Update (Combo) but I'm quite sure it started after I updated to this.
Has anyone had any experience with this and found any solutions, or have a troubleshooting tips for me or am I looking at an archive and reinstall...

Found out that the under the resolution settings for my external screen, there were two options for the native resolutions at the same Hz. Although both identical settings, one worked while the other did not...

Why do graphics and colors that appear on the monitor show up as blank spaces when printed out

Graphics (especially color) on emails and attachments show up as BLANK spaces when printed out.
Also, some color graphics and detail work of those graphics on familiar websites do not show up on my monitor
Both of these situations DO NOT occur on Explorer. With that browser - everything is OK

it may have worked, but gimping my system isn't exactly a solution, more of a band-aid.
its the equivalent of the old
patient says, " its hurts when i do *this* "
doctor replies," well, don't do that "
What do you mean "it may have worked" – did it or did it not?
Anyway it is not a remedy but diagnostics and if it makes a difference it points at the GPU driver as a likely culprit.

for the second error it is only on win8, on win7 i dont have this problem
On win7 the firs problem it is the same

a little difficult to figure out just what all your issues are but I'd suggest making an image of your system and saving to an external drive, then doing a restore back to out-of-box state and see if that fixes things. If not, post back.

Intel integrated graphics freezes when intel driver is used

So, I'm finally deciding to post here after a long battle with my graphics card. I believe there is an underlying hardware issue with it since I get BSoD's under Windows and seemingly random display freezes whenever I use the intel driver under Linux. This is not necessarily Arch-specific since I experienced the same problems when I used Ubuntu.
[edit]This is my graphics card according to lspci: Intel Corporation 82946GZ/GL Integrated Graphics Controller (rev 02)[/edit]
Symptoms:
Using the xf86-video-intel driver causes random, unrecoverable screen freezes that force me to restart.
After a screen freeze, I cannot switch to TTY and screen goes blank or stays frozen.
Screen freezes tend to happen when light to moderate graphics need to be drawn - anything from context menu shadows to OpenGL programs cause a freeze.
Setting Xorg intel driver option "ShadowFB" to "true" fixes the screen freeze issue, but the display becomes unusably slow. fbdev is faster than using the intel driver with ShadowFB on.
Setting Xorg intel driver option "DRI" to "false" and "Accel" to "false" does not fix the problem.
I am able to work around the issue entirely using the fbdev driver (xf86-video-fbdev). The results are perfect for my needs as I don't really use or need any 3d effects as I'm using XFCE. I am fine having only 2d effects as is the case with fbdev. However, the single problem that I'd like to fix with fbdev is that my mouse sometimes disappears when I perform certain actions, such as right-clicking, moving the mouse across the screen, or moving the mouse over a text input to change the cursor. The only way to get the cursor to reappear is to move it.
I'm not sure what sorts of files may be useful here. I would like to fix this problem either by solving whatever is the root issue with the intel driver or by fixing the issue with mouse flickering using fbdev.
Thanks in advance!

Thanks for responding. The freezing problem began a few years ago when I still used Ubuntu, I'm assuming there was either a kernel or intel driver update that broke it. Back then, when the screen froze I was still able to switch back to a TTY and errors that look similar to this would flood my terminal about 1 time per second (not my output, got it from this thread but it is identical to what I saw):
[ 4232.490910] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[ 4232.509642] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 120527 at 120524, next 120528)
The intel driver has been broken for me ever since then. I have tried several different distributions to try to fix it but they all produce the same error. Now, those errors do not show up and I can't switch back to a terminal as if the entire system froze. This is my kernel line:
BOOT_IMAGE=/boot/vmlinuz-linux-ck root=/dev/sda8 ro quiet
I've tried adding i915.i915_enable_rc6=1, i915.i915_enable_rc6=0, and i915.i915_enable_fbc=1 to my kernel line. enable_rc6 caused no changes, and enable_fbc led to X not being able to start. I also tried enable_semaphores but that produced no changes either (I think that fix only works for Ivy Bridge chipsets, my computer is older).
Enabling "Shadow" in my Xorg configuration as per the wiki did solve the freeze issue, but now I get artifacts on my screen. Taking a screenshot seemed to not show the corruption, so I recreated two common examples in GIMP of where I see artifacts:
Here, notice the highlighted line below where my mouse cursor should be. This stays for 500ms-1sec before the screen refreshes again and the artifact is removed.
And here, the desktop icon highlight effect is buggy.
Note that these are only two examples; I see this in many different places on my screen. I'm not sure whether my card is old or not. I believe it's somewhat older since I bought this computer at least four or five years ago. I've tried also using the xf86-video-intel-devel driver on the AUR as it is, but it also seems to be out of date so I also tried editing the PKGBUILD to create the 2.18-1 driver instead of the 2.16-2 driver. No changes with either driver.
Do you have any more suggestions? Thanks for the help thus far.

15" i7 Macbook Pro from early 2011.takes the mac laptop two or three tries to boot successfully. It would turn on, show gray screen, shut down, turn on again, show gray screen, shutdown, and then turn on, show gray screen, before it can finally get

Hello All,
I have a 15" i7 Macbook Pro from early 2011. The past few weeks, it has been getting increasingly difficult to get on my computer. It takes the mac laptop two or three tries to boot successfully. It would turn on, show gray screen, shut down, turn on again, show gray screen, shutdown, and then turn on, show gray screen, before it can finally get to the dark gray log-in screen. Even when I finally get logged in to start working, thinking it would be okay now, it shuts down randomly.
I've ruled out the possibility of a software problem because I've just done a clean re-install of Mac OS X Mavericks on my computer just yesterday.
I did upgrade the RAM recently, about a month and a half ago, from 4GB to 16GB, I went to the apple store four days after that upgrade to have them do a hardware test, and clean the inside of my laptop, which helped with previous heat issues. When they did the hardware test, the hardware was all registered as fine from their system.
I've tried resetting the SMC, PRAM, and doing the internet recovery hardware test, but to no avail. I thought I could at least find out what parts needed to be replaced from the hardware test but it seems that when the hardware test is almost finished, the computer just shuts down, So I am unable to see the results.
My computer is also having battery issues, under battery condition, it says "replace now," parts have been ordered, waiting for arrival. But if the battery health is low, it should still boot up fine, it would just hold a significantly less charge.
Could this be a hard drive issue?
Has anyone had similar symptoms and how was it resolved?
Does anyone know what I can do to alleviate this issue?
I haven't had time to take it to Apple because I'm currently taking a 21 credit semester academically. I'm an art and design student so my computer is basically the bane of my existence. Help! Any constructive advice is welcomed!
Thank you so much for your input!
-Christina C.

T410 with integrated graphics - DVI output not working on Mini Dock 3 (4337)

I tried connecting my external monitor to the DVI output of the Mini Dock and it did not work. I have since connected it with no issus to the VGA output.
However, I want to use the digital (DVI) connection for my monitor........how can i fix this issue?
NOTE: I have a T410 with the integrated graphics so my laptop screen does not display while docked (I keep the lid closed).

Hi MarkinIt,
Welcome to Lenovo Community!
As per the query we understood that you are facing issue with no Display when connected to docking station on your ThinkPad T410.
Have you checked updating the Intel graphic driver from Lenovo support site?
Please provide the current Graphic driver version showing in device manager.
Is the system having Windows 7 or Windows 8 OS?
Hope this helps.
Best regards,
Hemanth Kumar

My Imac is showing gray screen with red line when booting and restarts again

My Imac is showing gray screen with red line when booting and restart again, I can load it in windows 7 safe mode with red lines across the display, pls help

The graphic card is damaged. You can't do anything more than taking your computer to an Apple Store or reseller and getting your graphic card replaced.
Sometimes, when the graphic card is damaged, operating systems can't start. That's caused because the drivers that make the graphic card work detect an error, telling the operating system that the graphic card is unusable, so the operating system can't start and it restarts. However, you can start in safe mode because operating systems use a basic driver in this startup mode

HP Pavilion Elite m9065uk - Pink Screen Freeze and crash

Hi,
Hopefully someone here can help me. I have a HP Pavilion m9065uk Desktop and I am having problems and I was wondering if anyone could point me in the right direction.
Over the last month or so I have been having a problem with it the PC crashing, at first it started when booting up, it would get as far as the Microsoft loading bar then just a black screen and nothing. I would reboot and it would boot up fine, but then started freezing with a pink screen, then after a few minutes either go to black screen or nothing happening at all. Sometimes it starts to restart up then fails to start and startup repair comes up but sometimes fails. I changed the power supply back in March, but I dont believe if this has anything to do with it, the supply is the same as the original.
I googled the boards and it was suggested that the nvidia graphics card might be the problem. so reinstalled the drivers and then tried updating the drivers and its still the same problem. The reason I say i suspect the graphics card is that sometimes when the problem originally began I would get an error message saying that "display driver failed and recovered".
Is this a problem with the NVIDIA GeForce 8500 GT card? There is no Integrated graphics card on the PC when a graphics card is installed.
The PC will work for a day or 2 then the same pink screen crash occurs, now all of a sudden it wont boot up, keeps going to launch startup repair, which does not work. I can boot up to safe mode only.
Hopefully someone would be able to point me in the right direction. I dont want to have to go changing the motherboard or worse still pay for a new PC.
Any help would be greatly appreciated.
Thanks, O

Hi,
Is this HP PC the same as yours? It might be the video card or a weak power supply. Try reseating the video card and see if that makes a difference. Take a can of compress air and blow out all of the dust from CPU heat sink and the fan on the video card. See if that makes a difference.
You could try removing the video card and connect the monitor using a VGA cable to the integrated video port on the back of your PC. Hopefully your monitor has a VGA port and you have a VGA cable. The integrated video adapter is Intel so you will have to update the video driver. Look here for the update.
