I am trying to run BB10 Simulator to port my web app. The simulator runs okay until the point where I launch any apps on the simulator, then the app crashes and never loads. The fact that the simulator runs makes me think I fit the minumum requirement.
But after looking at my graphics card, I am not sure I do. Hence, the app crashes on the sim. Does Intel HD Family graphics cards fit the min graphics requirment of NVIDIA GeForce 8800 GT or higher or an ATI Radeon HD 2600 or higher?
The BB10 simulator doesn't really use GPU acceleration and I've successfully used it on a MacMini (i5 HD3000) and a Lenovo Laptop (i3 HD3000).
The simulator run the real OS, so unlike Ripple, if you do something forbidden (writing somewhere you’re not supposed to, accessing a resource you didn’t request – PIM, BBM ID, Internet) then the QNX kernel kills you. (Double-check the bar-descriptor.xml)
I’ve never used webworks, but it may be a good idea to install the Native SDK: Momentics (The C++/Cascades IDE) can be frightening, but there is a “QNX Device” perspective that can open a browser to the {simulator|real phone} file system and access to logs. You will have more detail explaining why your application was killed.

I installed the latest version of the HoloLens 2 Emulator (10.0.20348.1501) on my Windows 10 Pro machine. I have 32GB of RAM, 11th Gen Intel 8 Core CPU, Nvidia 3080 (mobile) graphics card.
Initially I thought that the HoloLens emulator was super slow (an input such as trying to move the pointer can take 10, 20, 30 seconds to show up and sometimes doesn't even show up).
But upon testing some more, I've realized that my inputs are going through immediately (as I can tell from the sound feedback), it's just the visual feedback which is not updating. This testing is just inside the OS (without trying to launch an app I developed).
Any ideas what could be going on? In the performance monitoring tool, everything looks fine.
In the end, the only way to fix it, was to disable graphics switching in the BIOS, and set to Discrete only - despite the fact that the Nvidia GPU Activity shows that the GPU turns on when I launch the emulator.
If the emulator takes 10 seconds to update the graphic, there should be configurations issues. Based on my test, though I cannot say it works fluently in my PC, the HoloLens 2 emulator runs at around 15 fps. There is delay but should be work fine for testing. (I am running it with Nvidia 1080 (mobile), with a much older CPU than yours.)
Please check the document on Using the HoloLens Emulator - Mixed Reality | Microsoft Docs and make sure you have configured your computer properly.
In BIOS
Intel VT -> enabled
Intel VT-d -> disabled
Hardware-based Data Execution Prevention (DEP) (or any Intel data protection related feature, display name could be varied) -> disabled
In Windows
After BIOS configuration is done, completely shut down your PC, then boot. (Directly reboot may not apply changes).
Run dxdiag to check:
DirectX 11.0 or later (12.0 in my PC)
WDDM 2.5 graphics driver or later (3.0 in my PC)
Hyper-V Checking
Enable it if it is not. Reboot is required.
If it is already enabled. Disable it -> reboot the PC -> enable it again -> reboot
Others
For the laptop, make sure the power supply is plug-in and it is not in power-save mode. Check the GPU payload (around 36% in Nvidia 1080 mobile)
Then you may run the emulator again to see if this issue still exists.
What I've done in the past is simply Dual boot, but I would like to not have to reboot my computer in order to switch OS's. Specifically, what I'd like is:
Computer would mainly run Linux,
When I want to play a Windows only game I can switch over to Windows, for that period of time then return to Linux.
Both Linux and Windows need to run up to native in speed.
I'm looking for suggestions in setting this up.
I've looked into Xen, however, I hear that Xen doesn't support 3D graphics? is this accurate. I've also looked into WineD3D and VMGL. However, Wine won't play every game, so I'd still need the Windows VM, and VMGL doesn't seem to work universally either.
I'm running two different machines that I plan to put this setup on:
Laptop:
Intel i7 4720HQ
16GB Ram
NVIDIA GeForce GTX 965M
Desktop:
AMD FX-8350
16GB Ram
EVGA GeForce GTX 960
I just joined and the "Tour" said, don't ask questions that could lead to a discussion than an answer. Anyway, If gaming is your primary goal, have windows as primary boot & dive into linux as VM. Otherwise you need to find a hyper-visor that provides 3D services or pass-through to your actual GPU.
There is a discussion here
I have dual booted windows 7 and ubuntu 14.04 on my PC.
I have a recurring problem with windows.
The screen frequently becomes blank for a few seconds, showing an error message in a popup menu:
"Display driver stopped responding and has recovered. Display driver NVIDIA windows kernel mode driver version 266.58 stopped responding and has successfully recovered."
Here are my computer specifications:
Intel core i5 processor,
4gb ram,
Nvidia GeForce 210 graphics card.
I updated the drivers on my computer.
I also formatted my PC, but the problem still persists.
Now the problem is worse and windows shuts down within a few minutes of starting.
Today, Ubuntu also started randomly freezing, a symptom which had not presented itself until now.
As Astor139 said:
Honestly, this particular question doesn't fit stack overflow, since it isn't strictly programming related. (As far as I can tell, you have a hardware issue.) Since it persists across two different OS, with very different arch, I would say you need a new gpu. A Nvidia GT 730 is under $50 USD and would be a suitable replacement/upgrade for your 200.
Posted as his comment is really a suitable answer.

I'd build a Windows 98 VM in my Mac with VirtualBox to run some old games, like "Z". It is running, but without the great soundtrack. When testing, I realize that the soundtrack is in midi files, and not even Media Player is playing any midi. It opens the file, knows time etc. (recognize the file) but no sound is played.
There is a Sound Blaster Midi Sinth installed, the problem might be the VM itself that don't emulate the full Sound Blaster 16 card. I'm thinking about some alternatives: to change the VM sound card (not a clue of how to do it), or to install a driver that synthesizes the midi in wave to use the wave port that is working, but didn't find one.
Also couldn't get in the Virtual Box forum, I'd make an Oracle profile, but didn't work. So here I am… any ideas?
(Although I did not try with Z or another game I tried with other/similar MIDI software...)
B)-setup-based (WinXP)
It works great with my B) setup (see below) based on a WinXP VM and the separately to be installed ICH AC97 Audio driver:
setup WinXP VM
set audio hardware emulation to ICH AC97
everything should work fine then without distortions or hickups
maybe choose Microsoft GS Wavetable over Microsoft MIDI mapper since the sounds are much nicer then
(the latest Realtek Intel HD Audio Driver for WinXP did not work for me - installed ok, restarted but was not found nor can be manually assigned)
A)-setup-based (Win7)
And then it works only basically with my A) setup (see below) based on a Win7 VM and
the Intel HD Audio driver (default)
some MIDI file played in Windows Media Player
but:
playing a MIDI file in Windows Media Player is fine
playing the MIDI file in my music software Band-in-a-box 12 over Microsoft MIDI mapper or Microsoft GS Wavetable is crappy with delays, jumps and distortions
It also seems to work with the AC97 driver on Win95 and Win98
(Trying with some MIDI-based music program I first thought it did not work and tried with all the available AC97, Soundblaster 16, Intel HD Audio drivers and did not see some MIDI device in the device manager.
But it seems MIDI support is not mapped to a device and the problems are related to the software I tried it with.)
my setups
Band-ina-box 12 as the app to test it
A)
no special XP exe emulation setup done
Win7 32bit guest
Win8.1 64bit host
Virtual Box 4.3.28 (latest, 2015-06-01)
B)
tried some XP exe emulation variants which did not help with the distortions and hickups
WinXP guest
Win8.1 64bit host
Virtual Box 4.3.28 (latest, 2015-06-01)
The standard MIDI port is 440, make sure your software is configured correctly to use the card (though judging by your level of knowledge in asking I'd imagine you've done this).
While this isn't specifically an answer about making VirtualBox do what you want, I'd recommend DOSBox when doing DOS or Win3x gaming over a regular virtual machine for performance and emulation accuracy.
You can get any DOS-based Windows (including 95) running on DOSBox or at least one of the patched builds of it (I recommend Taewoong's build at http://ykhwong.x-y.net/ as it is the most feature-complete). You could probably make 98, 98SE, and ME run on DOSBox too, but anything that won't run on 95 can probably be made to run on a modern version of Windows with less trouble.
I have an asp.net mvc 4 x64 web app that in the background does some calculations and returns some numbers to be rendered in the browser. All works fine in visual studio but when called from the project folder from the browser via IIS I get a CudaErrorNoDevice. This is error number 38 and so it does look like it's referencing all the external cuda dlls correctly, making the call and returning the error.
For testing I'm using the GetDeviceProperties() method.
I even plugged the Gpu into the displays just in case the browser got confused that the cuda call was for graphics. No luck though.
Can anyone confirm that calling the Gpu from a web app is a perfectly do-able thing to do? And if so, is there any specific configuration needed in IIS for Gpu's.
Thanks
IIS 8 Express, VS2012, Cuda 5.0, Gtx Titan (This is a 2nd Gpu, Gtx 660 is for display).
It's possible that IIS is running at a service level that does not have access to the GPU (which is a WDDM device in this scenario.)
The usual suggestion would be to switch the GPU device to be in TCC mode (possible with most Quadro and Tesla GPUs), but that is not possible with a GeForce GPU (both of yours are GeForce GPUs).
As an alternative workaround, you may wish to try the method described here.
The statement about TCC support is a general one. Not all Quadro GPUs are supported. The final determinant of support for TCC (or not) on a particular GPU is the nvidia-smi tool. Nothing here should be construed as a guarantee of support for TCC on your particular GPU.
