Another mix-and-match solution:
See this comment on Leshcat's Blog.
Alright, I'm back after some experimenting.
The good news - Seems I can consistently run Windows 8 now. This was done by installing the latest Intel HD drivers and Catalyst 12.11 drivers before installing Windows 8.
The bad news - I am stuck with this damn phantom monitor, which I think is what caused a lot of my issues to begin with. At the moment it is just reduced to being an annoyance.
Now that I think about it after having chased my tail so long, I'm presuming the issue here is that there is still no graphics switching occurring Instead, both adapters (Intel HD graphics and Radeon) are engaged simultaneously - resulting in this non-existent display being read by Windows. I would be content if I just had Radeon 24/7, but try as I may I can't seem to get rid of the Intel display for good. I uninstalled the drivers and blew them away with Driver Fusion... and Windows just finds its own generic Intel HD display driver to use. If I try to disable that, it seems to find some totally generic display adapter. Also uninstalled Intel WiDi just in case that was an issue.
I can't launch Catalyst Control Center from the device manager (even though there is a button for it somewhere in that display adapter). Doesn't appear in Control Panel under installed programs.. maybe I don't have it! Not sure where it would have went. If CCC is a requisite for switchable graphics working.. then that would be an issue.
Ideal world HP would/will release a package specific to the HP Envy 3070nr. Whether or not that will be the case is TBD. In the interim, my objective tomorrow will be to re-run that Catalyst installer package (wonder if I should download the one that's advertised as having .NET 4 support?) and see if I can get CCC installed.
@alphastar: thanks for posting the new min-n-match solution, will give it a go tomorrow as I suspect the latest intel are probably my best hope at regaining control on screen brightness.. I'll report how I get on as soon as I get around installing (it's also my work machine, so not always free to tinker)
@Jersey Tom: when you mentioned about your "phantom" display, I just realized I might be having the same issue... when I go on Devices (charm) from the desktop, I get options to project to a second screen. Now I hadnt thought much about it, as I assumed it was just my HDMI port, but then again I guess the correct Win 8 behaviour would be for the option to only show up if a screen is connected, correct? I tried projecting to the phantom secondary display, and sure enough I get a basic 4:3 output coming out on my laptop's screen, with vertical letterboxes..
so now I'm thinking you're really onto something about both graphics cards being on at the same time. It would explain:
- getting half the battery life
- getting OpenGL to work on programs (Sketchup) where it had never worked before (and worked instead for laptops with a manual BIOS "fixed mode" option, that Lenovo doesnt give)
The only thing that does not add up so far is that I've installed the AMD system monitor app, and while it does record heavy usage when running Sketchup, it drops back to zero during normal desktop activity. But I suppose it could still keep the display on or even when its GPU is in a low power state...
I will try test this tomorrow by disabling or removing the AMD card in device manager and report my findings. Tonight I still need Sketchup to work well though...
Yeah the "Second screen" appearing in my devices list from the charm bar was a telltale sign, for sure. Alternatively if you access the Screen Resolution settings (by right clicking on desktop or whatever) both displays appear. If you look at the properties of each, one of mine was the Radeon adapter and the other the Intel HD adapter.
Trying to disable the Radeon one is worth investigating I suppose... though I'd suspect it will be the same result as when I tried to disable Intel (i.e. that Windows will find a generic adapter to drive it).
I'm about to get ready for work.. but let us know if you have any success with that aspect, or getting Catalyst Control Center working.
thanks to everybody, for the responses. Actually i have an HP dv6t QE, 8gb, ati radeon hd 7690m xt (and intel graph), but like someone said, i think i will wait for HP to realease a driver for the 7690. If HP didn't release new drivers for this graphic card, what should i do? i really want to install windows 8
If HP were not to release updated drivers (and this contingency may be model specific), you can install and run Windows 8. My gut feeling is you'd be in the same position I am, where you can use it just fine but have the annoyance of a phantom extra "monitor."
AMD System Monitor or GPU-Z will tell you which cards are active (look at the sensors for temps, gpu utilization) - good for when you hear your fan on go-fast!
As for the Intel driver thing, I noticed that you CANNOT uninstall the driver completely since it is included with the O/S now (and also, it is always active - you can't uninstall your processor - ). Also, in More Info (related posts) and in this post explain that the Intel card is always active, because the framebuffer (output to the display) is shared by both GPUs.
About the ONLY thing you CAN do is force which Intel HD Graphics driver version is being used, by modifying the tab in Device Manager or running the Intel (or other) Setup.exe.
(On a separate note, I've confirmed that there is some idle issue with IE10 overutilization and the Intel HD Graphics driver...nothing scientific, but it definitely crashes with escalating fan usage when it should be going to sleep.)
@Bellavez83, Jersey Tom:
Word is, we should see a new Leshcat driver soon. I wouldn't count on a new HP driver just yet though...
There is already a 7690M solution - have a look at HOODY and adrynalyne's posts on Page 5, Rosterbyte and Zetlin on Page 6, and also Leshcat's Blog comments.
Ok, let me pose this question then... as I'm not entirely familiar with what this Leshcat business is all about. Does it control the switchable graphics on its own, i.e. without the need of CCC? Or does it take the place of the actual Intel and AMD display drivers?
Currently my issue is that both of my display adapters work TOO well... i.e. that they both seemingly are on at the same time. If I can actually install the Catalyst Control Center executable then perhaps I'll be up and running. Otherwise something needs to handle the switching (or just turn one off permanently - would be fine by me).
Leshcat has created a work around solution to the issue that exists between the Windows 8 operating system environment and the AMD/Intel switchable graphics driver. The switchable graphics driver makes it possible for Windows 7 to act as a bridge between both the AMD and Intel GPU's. It allows both the user and/or the Windows 7 OS to decide which of the two installed GPU's [AMD/Intel] on there system should be used and when they should be used to better provide performance or efficiency.

While this drivers was designed specifically to run in a Windows 7 environment, it does not work as intended in a Windows 8 environment. Windows 8 automatically installs a driver for both the integrated Intel based graphics, and a completely separate driver for the discrete AMD based GPU. The two under Windows 8 are not unified in anyway without the presences of the Catalyst Control Center (CCC) software, without which the two GPU’s will not work in tandem or be unified.
Users can choose between either the Intel graphics or the AMD graphics, but not without sacrificing either performance or efficiency. Users, without the Leshcat Beta driver, will also lose the ability to install the AMD Catalyst Control Center, which is essentially a Graphical User interface or GUI that allows users and the OS to actually control and switch between the two graphics cards as necessary.
Leshcat now provides a unified version of the two drivers, which restores the ability to install the AMD Catalyst Control Center (AMD CCC) in a Windows 8 environment. However, there are still quite a few bugs that yet have to be worked out with the Leshcat driver set. It's still in the Beta stage of its development. It should be considered an acceptable work around, but it cannot be considered as a fix to the AMD/Intel switchable graphics issue at this point.
It will, at best, allow users switch between their AMD and Intel GPU, but not in the same way as with the original HP authorized driver that worked under Windows 7, which does it more efficiently. Users of the Beta driver may experience excessive power consumption or conflicts with other installed software or even the Windows 8 OS, itself. Many users who have installed the Leshcat driver, in a Windows 8 Pre-release version environment, have found that in order to get everything to install properly, there had to be some changes made to the system's registry, which caused the OS to begin to run in Test Mode.
