    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).

    No! The AMD Catalyst Control Center controls switching between your system's integrated and discrete GPU. Leshcat restores your ability to successfully install and use the Catalyst Control Center in a Windows 8 environment is all.
    10-4, thanks for the clarification! That makes a lot more sense. For the time being I'm at least functional as it stands, even if not to perfection. I can deal with a phantom monitor for a bit. Might give it a few days and let the dust settle and then probably dive into Leshcat

    After 4 days of endless screwing around to get to a point of stability, I'll hold onto that for just a bit

    Edit: Sorry OMG, didn't see the new posts before.

    Anyway, to answer the first question - Leshcat is custom-brewed (from original Intel/AMD versions, including Catalyst Control Center = CCC), 3rd-party-built, community-supported (see Blog), Intel + AMD drivers to enable Switchable Graphics. Prior to the public Windows 8 driver releases, this was likely your best (maybe, only) option. Bottom line, it works.

    As long as you know that when the AMD card is active, so is the Intel, then you will probably be quite happy with the outcome of your Leshcat test (the others were).

    No problem, I just replied to your other post elsewhere.

    Check this out - UnifL Manual (read carefully, the screenshots will also help)

    Post any questions that you come up with after.

    @alphastar: thanks for the heads up re. new Leshcats coming
    @Jersey Tom: so haven't yet got round to try the HP drivers yet, but indeed verified that both AMD and Intel cards are working at the same time, as I also see a phantom 2nd screen in the desktop Screen Resolution panel ("available display output on Intel HD Graphics"). I also get a "another display not detected" phantom monitor turn up if I hit "detect" in the same panel.

    I am on Leshcat 12.9 beta now, and I do have the CCC successfully installed. It does seem like the ability to manually configure which programme uses which card does work, but I also suspect the AMD card may not actually ever fully turn off, which really murders my battery life.

    If I understood correctly from what OMG was saying earlier, the excessive power consumption I am experiencing (had it before installing Leshcat drivers, which did not seem to make the issue better or worse) may be caused by the separate way Win 8 handles the Intel and AMD drivers? anybody else here experiencing battery life cut in half on a switcheable latptop?

    I have been following this thread since I found it on Sunday. I have been having many of the same issues described in this thread. I've learned a lot this past weekend for sure. I am running an HP Pavilion dv7-4077cl Notebook with an AMD Mobility Radeon 5470 HD + Intel (Gen 1) switchable graphics card. (Thanks to all the previous users posting screenshots; I would not have known how to find all that out.) I downloaded and installed Windows 8 Pro on Saturday and after much consternation and nuking my install a few times I dual booted it along with a good, working Windows 7 install. (I recommend that for all looking to upgrade. Good to clean install on a partition, this way worst case is you nuke the Win8 partition and still have your Win7.)

    Needless to say I found this forum and thread after much Google/Bing searching and has been a Godsend. I bookmarked it to my IE10 because I expect at whenever an official solution comes this thread will light up like Christmas. Until then, I installed the leshcat Band-Aid which suits my needs just fine (Test Mode watermark is annoying, I probably did something wrong, but hey it works).

    I do have a question regarding the leshcat drivers and those of us who have installed them. Let's say AMD does release an official fix. Is there a procedure by which I can remove the leshcat drivers and install the official switchable graphics driver... or is this too far off yet?

    Much appreciations to those of you smarter than I who are testing and retesting solutions for all of us. Glad to know it's not just me.

    Great to hear, that's exactly what this thread is here for!

    In terms of Leshcat and upgrades, there are 3 options:

    1) Upgrade from old Leshcat to new Leshcat (simply install, no prep [or other steps] necessary)
    2) Upgrade Leshcat with newer AMD (looks the same as 1, basically run the AMD Catalyst installer (CIM) by running the new AMD .exe)
    3) Remove (using Treexy DriverFusion) and install new/other drivers (detailed instructions in the Leshcat Manual)

    P.S. Test Mode is normal, it is because Leshcat's drivers are signed differently from the original Intel/AMD/HP - see here for fix.

    Hey guys, ive got the same problem it seems pretty much everyone seems to have with switchable.
    I am currently running a HP dv6-6c38tx which has the AMD 7690m xt and intel hd 3000. however in my device manager i am told i have a 6700m and intel hd graphic 3000. looking through all the posts i am just a lil but confused about how to get these drivers to work properly. before win 8 everything was fine with catalyst 12.2 beta drivers but since the change over Ive had no drivers, so i got the latest CCC version,now i have no option for the switchable Graphics and everything lags like a b*tch. whats the best option just in terms of performance and stability for gaming when it comes to all the drivers. is Leshcat the way to go?

    Thanks in advance

    Well there's nothing new for your card, (same as mine) On HP site it still shows the old Nov 2011 driver for W7, under W8 there is nothing showing for graphics driver at all.

    If your using W8, you can go here [Drivers] HP dv6-4XXX / dv6-6XXX / dv7-5XXX / dv7-6XXX / ENVY 14-2XXX / ENVY 17-2XXX (INTEL) - Page 41 and try that (leaked) HP driver for this card.

    If not than you can run over to Leshcat's site and try his, but I think he's about to release a new 12-10 so you might want to wait for that. They will have the latest AMD and Intel mix.

    As for AMD, I'm still waiting for their "final" Enduro release, maybe in another month or maybe not till Jan, I'm still waiting for AMD to make a tool that actually finds this 7690M XT and any other 76xxM card and supports these cards, but I'm not in any hurry now. I have my W8 install key and disk and can wait, I have everything working on my W7 now and don't need to run around looking for scanner or printer drivers too.

    For now I sit on my OEM HP nov 2011 graphic driver, and will only update when I see a new one listed for both W7 and W8, and that actually installs "as is" and works.


    Good Luck with that 7690m xt smirks
