Okay, the manual method just told me that "The best driver for your computer is already installed" and then it listed "Intel HD Graphics". I used the same properties panel to uninstall and trash the driver which reverted it to the Standard VGA driver and retried the manual method. The computer this time said "You already have the best driver installed and it listed "Standard VGA". WTF?!
I restarted to be sure all old anything was gone and then used the automatic install. It ran through the process but never did install the driver. Now, when using the auto install of the file referenced in your message below it tells me
"The setup program will install the following components:
- Intel Turbo Boost Technology Driver"
Is this the graphics driver? It does not say GMA or Graphics or anything of the sort. In any case, it goes through it's paces as before but does not install any driver. If I scan the hard drive for available drivers, none come up.
I then tried the older one (the R297600 or whatever it was) and the setup screen on this one said "This will install:- Intel HD Graphics Driver, Intel Display Audio Driver and the same turbo boost thing as above". Computer restarted and when it came back, the display resolution had changed and the driver listed in the device manager said Intel HD Graphics (no mention of GMA).
So then I Googled Intel GMA driver but, having read the Minecraft thing about how Dell forces you to use customized drivers I then Googled Intel GMA Driver Dell Latitude 6410 and got the driver you had already pointed me to - the 296701 one. Thinking I might have something here I uninstalled the previous Intel, which took me back to the Standard VGA but then when I went to install the 296701 driver all it was going to install was the Intel Turbo Boost Technology Driver. I reinstalled the 296700 driver package and then the 296701 on top of that and with fingers crossed, launched PixelCNC.
No dice. But I have now made the connection that GMA must be the same ting as the Turbo Boost stuff?
Ultimately I guess we've gone in a big circle and are back where we were. Is there a way to determine if there is an NVIDIA hiding in this machine or should I just try the drivers? I should note, the manual install wasn't that straightforward. Anything I tried after clicking the "Have Disk" option failed. The only way to see any sort of install was to click "Browse for a list of available drivers installed on this computer" and then select the Intel HD Driver. But that's when the above "You already have the best driver installed" happened.
So frustrating.....PixelCNC looks like exactly the solution for me - I have seen image2Code and other methods and techniques and they pale in comparison I'm pretty certain. I'm determined to keep at this until you tell me "I think we're screwed". I hope we get it.....
