3 Monitors on E31 using integrated & discrete gpu?

I can't get the integrated graphics to show up in the device manager. I reset the BIOS to IGD and enabled multi-monitor support as per : http://download.lenovo.com/express/HT062445.html
I'm stuck...any ideas to get my 3rd monitor up and running?

How can I tell if I'm using my discrete Quadro 1000M GPU?

I just recieved my w520 in the mail today, and I have no idea how I can tell when the optimus kicks in or if it's even using the discrete card. I already downloaded the driver for the 1000m. Anyone know how I can check what card it's using?

See File Edit Desktop Help in the menubar. Select 'Desktop' and look there in the dropdown menu :-)
You can use 'autoselect' for general use, discrete for performance. Most people suggest autoselect and changing it when you need to, or better just go to the menu I mentioned and select 'Add run on graphics processor' to context menu then you can select the gpu to use from explorer.
What you mentioned, 3D Setting, Manage 3D settings under Select a task is another place you can select which processor to use by clicking program settings on the right and creating a profile for the app you intend to run.
Btw what do you mean on your question then? Either the activity monitor shows it running on the Nvidia gpu or it's not. If you wish lower level information on how this works you might wish to peruse some doc on Nvidia's Optimus switching, it may help you but I think the gpu monitor is what you want :-). Basically with our w520s if it is on the external display it will be run on the discrete gpu (I think I read the external video connectors go to the discrete card), if you have your laptop lid open, you could select Nvidia or integrated. The driver can also override your selection. This is my rough understanding of how our systems are wired and how things work. Someone add to/or correct this if they wish. You may wish to look for some articles/discussion on the hardware switching/muxing and how that works between the gpus. I need to reread it all myself.

It seems that there is a problem with my nvidia GPU + optimus, if Firefox uses the nvidia gpu the whole GUI is messed up to the point of being unusable, if I force to use the integrated (intel) gpu runs ok

I have a laptop with an Nvidia card (335GT) with optimus support, when I run firefox with the Nvidia GPU the buttons flicker around, sometimes they disappear. the menus doesn't show, some text in the screen doesn't show, etc.
at first I trough it was an extension so I disabled every extension but no luck.
Once I noticed that Firefox was using the nvidia gpu I trough on forcing it to use the integrated card (intel HD) to save battery, to my surprise the problem corrected once I did it.

Why does my Thinkpad W541 use Integrated graphics in WoW instead of the nVidia Quadro K1100m?

I have seen reviews by many people on the W540/541 and they all said they were getting around 100 fps in WoW and even the guy in this video was able to play it on high-setitngs: http://www.youtube.com/watch?v=j0j045vg3W8 Don't get me wrong I use this device for mainly professional work, but every now and then I would like to be able to play a game on it or two. thanks!

According to a number of contributors on a number of threads regarding the same subject, THIS IS BY DESIGN.
If you want to force use the K1100m on the W541, it will need to be (a) on an external monitor and (b) controlled through a dock, rather than via the video connectors on the laptop itself. According to "the specs", the laptop screen is always handled by the Intel Graphics... no matter whether the W540/W541 BIOS is set to "basic" or "advanced" graphics mode.
According to the following description of how graphics works in W540/W541 and newer machines (which is that Optimus Mode is always active, although you can select "basic mode" or "advanced mode"), you simply MUST use Optimus Mode and cannot disable Intel Graphics as you could with the W530.
Now I'd always thought that in theory for the laptop screen you can use nVidia Control Panel (3D settings) to specify which programs you want to get nVidia graphics for when those programs' windows have focus). But my experience (granted, with the W530 and not with W540/W541) is that nVidia graphics kick in (and take over for Intel graphics) reliably only when the firmware determines that graphics performance requirements justify it.
Strangely, the description of Optimus Driver behavior (below) makes no mention of the NVidia graphics ever kicking in for the laptop screen, but I thought that was how it worked. Confusing and contradictory descriptions, seemingly. You'd think that gaming applications would be just such an example of "graphics performance demands nVidia graphics", but your thread subject suggests that nVidia is NOT kicking in (I assume you're running on your laptop screen, and have probably tried to go to nVidia Control Panel to request nVidia graphics when you run WoW), which would be consistent with the written descriptions but very definitely annoying. On the W530, Optimus behavior had the K1000m definitely kicking in on the laptop screen when needed.
So apparently by design Optimus is always active on W540/W541 and newer machines. You can´t actually disable the integrated GPU at all and force the use of the discrete graphics, as you can on the W530 for the K1000m nVidia graphics via its BIOS. Here is the description of Optimus Drivers for W541, which describes Standard vs. Advanced mode, and by implication how the new W540/W541 BIOS design works:
STANDARD and ADVANCED MODE
In Standard mode, all dock displays uses Integrated Graphics as display output
and is limited to a maximum of 3 displays including Computer's LCD.
While in Advanced mode, all dock displays uses Discrete Graphics as display
output and it increases the maximum number of displays to 6 including Computer's LCD.

W520: Optimus stop working after use of "discrete graphics only"

I have issue with Photoshop and Optimus, so I am forced to use discrete graphics only. It is an other story...
Issue is that when I choose discrete graphics everything if fine but when I change back to Optimus mode Discrete stops working. If I set some program to use quadro 1000m in Nvidia menu, it doesn't use it. They all use integrated graphics. I realized the problem when I checked Lenovo Power Management and Nvidia should have been on... It was not.
Problem is gone if I reinstall drivers but it's not nice to do every time. I use latest updates from Lenovo Update and my BIOS is 1.34.
Multiple display setup works while the problem exist, so Nvidia is still working but Optimus does no...
It would be nice if someone could try switching to "Discrete only", load OS, restart with Optimus and check if it can still use Nvidia GPU.
My english is not that good and if there are any difficulties to understand my point PLEASE ASK!
Cheers
Antti

RDP full-screen mode in Mac OS X Yosemite requires discrete GPU?

RDP works great with Mavericks and requires only integrated Intel GPU. But when upgrade to Yosemite, It requires discrete GPU every time I go into full-screen mode. Which is pretty annoying without power supply.
I am using MBP 15-inch Mid 2010.
Any possible solution? Thanks!

Hi,
Thank you for posting in Windows Server Forum.
Initially please update MRD MAC to v8.0.10. From description it seems that issue related to MAC side compatibility issue, so suggest you to contact apple customer care and clarify for further research.
Thanks for your understanding and Support!

Is it possible to completely disable the discrete GPU?

My discrete GPU is damaged, and the computer keeps getting Kernal panic whenever it uses it for a few minutes. I have to stick to the integrated GPU, but the computer keeps switching to the discrete GPU and causing my computer to crash. Is there some kind of Terminal command I could use to disable it?

Macbook Pro 17" early 2011 Discrete GPU failure

Hi, before I start, this is the serial of my MBP so you can identify the exact model.
MBP 17" Core i7 2.2 Ghz serial number C0*******F92
My Macbook pro 17" (early 2011) started to freeze once a month, but then, it started getting worse. I narrowed down the problem to the discrete GPU graphic engine as I was able to disable the automatic switching and be able to use the system with most of the programs.
I googled around and learned that this problem happens to all early/mid 2011 MBP and iMac models that use AMD 6750M engie (if I recall well).
When the system is on automatic graphic switching mode, whatever app you use that requires the graphic engine switch (VMWare Fusion, Photoshop, iPhoto, etc), causes the system screen to freezes. The system although unstable, keep working as I am able to log into the system via SSH. Trying to reboot via shell (sudo reboot) won't work as there is some frozen process preventing it, but system is alive.
You have to power cycle the MBP between 2 and 6 times to be able to get it to boot as most of them time it freezes during the boot process.
I want to know if there is an apple warranty to this problem ( I don't have apple care on this machine). If not, what will be the cost of the logic board replacement and how is the procedure to get it done. I live outside of the US and can send the machine if needed.
Thanks in advance.
Regrds.

When I try to play flash games it uses the wrong gpu

When I try to play flash games it uses my integrated Intel gpu not my dedicated Nvidia one. Other games use the correct gpu, however. Is there any way that I could possibly force flash to use the correct gpu? I can't change it through the Nvidia settings as it is apart of browsers and I can't change browser gpus.

Unable to find ANY GPU settings in Firefox.
I don't use IE or Chrome, so I can't say how to even check them.
Nvidia forums have NOTHING on forcing a browser to use a specific GPU, and I know Flash has nothing in settings to do it.

Gx70 is not using its dedicated gpu

Hello everyone,
A week ago i bought a msi gx70, it al works perfect except for one thing. When i start a game, the laptop is not using its dedicated gpu (amd hd 8970) but the gpu integrated in the processor ( amd 89650 )
I've tried a lot of stuff to fix this, like disabling the onboard gpu. When i disable the onboard gpu, the pc start using a microsoft basic render drive. I also tried to uninstalll both cards and reinstall them, not working. tried going into the bios, but there is now option for me to disable the onboard gpu there.
So please, i need help because it's getting pretty frustrating.
Thanks in advance!

OP, please let us know if those worked or not. So that we can eiher continue to help, or if it worked reply with what you did to fix the matter. So that any other users experiencing the same issue, reading this, will know what to do.
I will, but for the moment i can't :p
I gave it back to the shop to see if they can fix it and my laptop suddenly black screened after i updated the drivers. So i hope they can find some drivers where i can just manually disable the integrated gpu.
Also, when i was playing games the power button was orange if i remember correctly, but the game was still very laggy (about 40fps on smite, which is too low for this card) and in black ops ll the fps was really unstable (immense drops from 120 to 30) i think this also shouldn't be happening with this card right? And in games where you CAN manually pick the gpu, the dedicated one was just not given as an option. Also in benchmarks the dedicated card was noticed by the benchmark, but not used for some reason (having 20fps in a benchmark with this card at medium settings).
All this concludes for me that the dedicated gpu was not processing when ingame.
This is all the information i've gathered, if you have any other thoughts of what it could be, feel free to give them.

Not green: No sleep when using integrated card reader and hub in Dell 2709

Hello,
here's a little weird sleep and wake-up problem with a Mac Mini.
I hooked up a Mac Mini Mid 2010 model to a Dell 2709 monitor which has an integrated and self-powered card reader built in and this is connected by USB to the Mac. To the mac this appears correctly as a usb self-powered hub. I am using a so called master/slave power socket to put every periphal to sleep when the Mac enters sleep (stand by) mode. The Mac itself plugs into the Master socket and when turned on it also switches on the Slave sockets, and the monitor. Shutdwon and sleep turns the slaves off. This works good until the monitor USB hub is connected to the Mac. Then, when the Mac enters sleep state, it wakes itself up again within 1-2 seconds. The wake-up reason seems to be the USB hub from the monitor, because the hub looses power due to the master/slave power panel and disconnects from USB, which in turn wakes the Mac up again.
Now, i got also a Bootcamp partition with Windows 7 installed on the same machine. To my surprise this works as expected. It enters sleep state (called StandBy Mode in Windows) without wakening up again immediately by itself. I assume the reason for this different behaviour is just the different approach from the two OS's. OS X wakes up even when disconnecting USB gear, but Windows does not.
It took some hours to find out this. Apparently other users in this forum also have this problem in this particular scenario, like here:
http://discussions.apple.com/thread.jspa?messageID=11031781&#11031781
Unfortunately the topic is unanswered and archived.
What would solve this problem is of course to change the power connection for the monitor in a way that the integrated USB stays powered. That would be pragmatic but not be "green".
Another approach would be to change the behaviour of the Mac to not wake up when a USB device is disconnected - which makes no sense to me personally at all. I'm new to OS X and didn't found any command to achieve this.
Would be nice to make real power saving working again.

Hi David,
thanks for your reply. You mentioned that the hub in the monitor is sending some sort of signal when powered down and this causes the wake up. Good idea. To inspect this i played around a bit with some other different USB gear on the same Mac.
I discovered that any&every device that is disconnected by just unplugging it from the sleeping Mac Mini wakes the computer up again.
This example from the kernel log shows a connected Canon ip4000 printer:
Sep 16 00:26:52 MacMini2010 kernel[0]: AFPSleepWakeHandler: going to sleep
Sep 16 00:26:56 MacMini2010 kernel[0]: Ethernet [AppleBCM5701Ethernet]: Link down on en0

Sep 16 00:27:02 MacMini2010 kernel[0]: AFPSleepWakeHandler: waking up
OK, this device is also self-powered. But what about a thumb drive?
The same can be reproduced with USB thumb drives (all other USB devices were unplugged before, the Mini was sent to sleep via the power button):
Sep 16 18:16:29 MacMini2010 kernel[0]: Ethernet [AppleBCM5701Ethernet]: Link down on en0
Sep 16 18:16:29 MacMini2010 kernel[0]: System Sleep

Sep 16 18:16:43 MacMini2010 kernel[0]: The USB device Cruzer Crossfire (Port 1 of Hub at 0x24000000) may have caused a wake by being disconnected
So, either:
- OS X or the Firmware can not distinguish between connect and disconnect and wakes up the computer at both events. The log above shows the opposite in the last line.
or:
- This behaviour is by design. (But makes no sense for non-block-level devices. Unplugging = Wake-Up?)
or:
- Something with EFI ?
Now i am poking in the dark.
The Unibody-Mini is really a light-sleeper...

Possible to disable discrete GPU on MacBook Pro?

Hey all, I have a Mid-2014 Retina MacBook Pro with dual GPUs. I've got most everything set up just right (enabled powersaving on CPU/IGPU, disabled bluetooth/webcam/sdcard, etc), as such I have switched from the NVIDIA graphics to Intel Iris Pro by chainloading the apple_set_os.efi patch through GRUB, removing the nvidia driver, and installing the Intel one. Now, I need to know if there is a way to completely power down the discrete GPU, acpi_call-git from the AUR does not work. Any ideas?
Thanks?
EDIT: I use gpu-switch, a utility for MacBooks that lets you specify which card you want to use on next boot. I am not sure whether this completely powers down the other card, I don't think it does since it still shows up in lspci and I still have bad battery drain. I will check vgaswitcheroo. I have the Intel GPU working, but I want to fully power down the other one to prevent battery drain.

Hy there,
you can try it with this entry (gfxcardstatus) in the wiki if and only if you have OS X on a bootable device!
https://wiki.archlinux.org/index.php/MacBookPro10,x
I did that on my MBP early 2011 with the defekt AMD / ATI card and it works great!
BUT ATTENTION you need the 2.2.1 Version of that program!!!!!
Earlyer or later versions WONT work!!!
Here you go: https://software.com/mac/apps/gfxcardstatus/2.2.1
Hope that helps in the first place (i know it is quick and dirty....but it works)
P.S. if you want t know the status of the GPU's you can do it with that : cat /sys/kernel/debug/vgaswitcheroo/switch
comes from the ubuntu wiki: https://help.ubuntu.com/community/Hybri … switcheroo
Let us know how it works

Only Use Integrated Graphics When Using Battery

Can someone tell me how I can set-up my 2011 MBP 2.3GHz i7 so it only uses Integrated graphics card when I am using the battery? I just upgraded to Lion 10.7.1 and my barrery life stinks. I downloaded and am using gfxCardStatus and set it to Integrated graphics only for battery power. When I launch Twitter and other apps (Angry Birds), it still switches to Discrete graphics. I also set my Energy Saver Preferences to Automatic Graphics switching to help preseve the battery.
Thanks

First, go to iMovie/Preferences and enable the Advanced Tools.
Import the video clip into an iMovie Event. When you get ready to use it in an iMovie Project, select the clip in the Event and drag & drop it on top of a video or photo clip in the project at the place where you want it to begin. When the pop-up menu appears, choose Audio Only.

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. How do I fix?

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. This means I can't use the computer anymore. How do I fix? I tried using the Command+F2 keyboard shortcut, but it doesnt' work. It's possible that since I reinstalled the OS, it still needs to be set up, so there's only a welcome screen (but since I can't see it I'm not sure).

There is no limit to the number of times you can re-install Office on the same computer.
