LV2GO++ has reached version 1.0! However this is still in BETA since i'm the only that has been testing it.
I have tested this tool on driver 275.27 international and english language and 260.xx english language only.
Therefore I am preety confident about its robustness this time round! Nvidia changed the way the control panel gets installed from 270.xx and to 275.xx so this tool takes that into account. Also this tool is only for drivers 265.xx and above!

What Is this?
This tool is written in C++ and is designed to modify quadro and geforce desktop drivers to make it compatible for laptop systems.
This tool is different to Driver Heaven's Mobility Modder in that it has more options tailored for each system type. Such as install options for Hybrid Optimus and Hybrid SLI. The modification process itself is extremely quick compared to Mobility Modder. However this come at a small price: the driver will only install english language in the control panel. The tool modifies .inf files found in Nvidia driver packages. It does not fix bugs associated with the driver only adds compatibility and add settings to force Hybrid SLI and Hybrid Optimus.

Laptop drivers can be installed however make sure to delete all other .inf files in the Display.Driver Folder!

Whats New Since 0.2 WIP?
Along with the usual bug fixes to the install process I've added ability to check if driver is Optimus compatible (which you can turn off by going to tool->un check Optimus Test) also added ability to save user settings on exit. So when you load the tool again the settings you used will be loaded automatically.

Full Changes:
Spoiler


Supported Cards
Supports Quadro and Mobile GPU from Geforce 2 to GT500 series and quadro equivalent.

Full List:
Spoiler


Hybrid Optimus User Tip
Modify Desktop NVAK.inf file found in official nvidia driver packages for max compatibility!

Still impossible to install 270.80 and 270.57 on M17x R1 with 9400m and 280m sli, vista x64. It says it's not compatible with this version of windows, when I clearly downloaded a seven/vista x64 driver.

Psychotic Deformity,

thank you for testing this app! Based on your feedback i have found an error in the code that only affects vista x64 users!
Let me show you:

else if (ui->ModValue->text().contains("WIndows Vista x64"))
    {
        inf.AddSection("NVIDIA.Mfg.NTamd64.6.0");
    }

Should be

else if (ui->ModValue->text().contains("Windows Vista x64"))
    {
        inf.AddSection("NVIDIA.Mfg.NTamd64.6.0");
    }

see the typo? Therefore the relevent section that identifies your gpu and os is missing.
Thanks for the feedback I am uploading a new build now!

lol I was staring for 1 minute before I could find the typo xD

So I tried with the new beta, and now I could install the 270.80 drivers.

However, the hyrbrid switch is not working correctly: disappears them reappearsfrom taskbar, impossible to switch through keyboard (fn +f6). And the nvidia control pannel is completely empty, takes ages to load, I just have the performance options (that come with nvidia system tools).

Will have to try with other drivers and see if the results are the same.

Yes unfortunately nvidia has officially dropped support for Hybrid SLI users :)
The setting i include are there which worked well in the past so its hit and miss whether it works 100% :).

I have the same problem with you in the 270.xx drivers in terms of control panel. I switched to 275.xx and all is good.

Tried with 270.75 from Dell and have exactly the same behaviour with hybrid switch and control pannel.

The thing is, I already tried the 275.27 drivers and don't need any modding to install them. But they gave me BSODS when switching cards or freezes and driver crash when suspending cuda work in BOINC, so had to drop them. And the

You say hybrid-sli support from nvidia is no more, but isn't it only for intel motherboards, something like that? The M17x R1 has an nvidia motherboard, and I can install verde drivers just fine, for now, so it is still supported according the release notes. So the verde drivers must contain the files necessary for hybrid-sli to work on nvidia MB systems.

Anyway, thanks for your hard work man :)

Hi the 275.27 contains a desktop version.
They are the same driver files as the 275.27 mobile versions.
Only different inf and settings in the inf.
If you want to you could mod the 275.27 desktop with my tool and see if that helps.

cheers for all the feedback.

Ok I tried modding the 275.27 drivers with the app. It passes the system check, then when installation starts it says: "nvidia installer failed".

"This graphics driver could not find compatible graphics hardware"

My Quadro FX Go1400 : PCI\VEN_10DE&DEV_00CC&SUBSYS_019B1028&REV_A2

Tried modifying nv_disp.inf and the nvak.inf (for shits and giggles) same results...

Maybe I am using the wrong file? or doing something else wrong, no real guide on how to do it, so just went by what I used to do to get drivers to work.

"GeForce v275.27 Windows 7 x32" <--- drivers/system in use....

Bleh...

wierd i added that card in for this release based on your comments.
I have looked through the source code and eveything seems in place.
Can you upload the .inf file that was modified for me to look at?

thanks

Dox,

When you say "Laptop drivers can be installed however make sure to delete all other .inf files in the Display.Driver Folder!" Are you referring to specific drivers? I tried removing all of the .infs from 275.27 (which says it is OEM mobile) and it fails with :: "NVIDIA Installer Cannot Continue: Required files are missing"

It installs fine without removing the other infs, but for some reason my computer has been randomly rebooting, preceeding by the graphics driver (unknown whether it is nvidia or intel) freaking out -- artifacting, lines, shuttering, etc. no BSOD is left, and nothing appears in the event viewer to give me an idea the cause. Since it is screwing with the graphics, I figure it at least might be the nvidia card / driver, and therefore could have something to do with the infs?

There is at least a semi-decent chance that something is hardware wrong with this machine, but for the moment, I am assuming otherwise.

Thoughts? (thanks in advance for your help)

Edit -- I have reinstalled the drivers performing a clean install using this version (the first time I did it, i was using .1 beta, if you think it makes a difference. I'll report in 24 hours approximately if anything is different (seems to reboot randomly roughly 3-4 times per day (and often in a string (over maybe 6-8 hours).

Hi so you have win 7 x64? thats same version as my OS i dont have any install issues when i mod 275.27.
I recommend you modify the 275.72 desktop version choosing nv_disp.inf. You deleted all the .inf? do not do that.

Let me explain:

I dont recommend modifying laptop drivers which includes lots of infs in the folder since they are oem specific infs. Those infs has subID of graphics card which may/will overwrite the settings you chosen on my tool (depending on what inf file you chose to modify)

For example:
you have a dell - your oem specific inf = nvdd.inf (i think) and say you modified nvam.inf. The nvidia installer will install the driver with the nvdd.inf as it has the subid for your card. I only add the 'global' identifier id in the mod otherwise it would be very slow and impossible to add every sub id for every car for every mobile gpu! So you need to delete all the .inf files and leave nvam.inf!

When i say delete all the infs i mean delete all of them but not the one you modified!!!!! as it contains install instructions to the nvidia installer.

So in short do NOT modify laptop drivers but modify and install desktop ones for ease of use.

Hope this makes sense. Feel free to ask more questions as i know it can be a little complicated.

Can you confirm LV2GO++ v1.0 beta2 works for you or is it just 0.1BETA?

Isn't the x64 bit 275.27 a mobile OEM driver? The modified inf from lv2go is nvwi.inf, so i had downloaded that one and used your mod on it. perhaps i'll go back and try installing with nv_disp.inf.

the infs I had deleted were everything but the one i had modified, but it won't install that way. (perhaps i needed to keep nv_disp.inf and ignore nvwi?) if i select nv_disp.inf, it tells me it is not 100% compatible with optimus.

I uncovered another bug though. if you ignore that error and don't mod the file (clicking the close box instead of okay), it deletes it instead (And doesnt save the original version).

Hi Dox,

Thanks for adding the GeForce Go 7950GTX.

Using 1.0 I've successfully modded and installed 270.80 (and Dell 268.27) for Vista 32 bit.

Neither support the Nvidia Control Panel at all (which you have commented on).

I will try 275 next.

I dont feel like writing a long post on this so heres a quick answer :) :

download 275.27 from NVIDIA's website. Make sure its DESKTOP version.
Browse to nvak.inf and mod that file.

Also the reason its not installing is because you DOWNLOADED the modified inf and tried to mod that! :P Modify only the inf that is in the driver folder already not the modified inf.

The modified inf on this site is bascially a hand made version of this tool. This tool is made so you dont have to wait for the modified inf for each driver :)

I just tested your bug report and cant seem to recreate it?
So i browsed to an inf. Otimus check pops up. I click the x to exit (not ok) and everything is fine.
If i dont want to mod the file i click reset (tool->reset) and everything is fine.
If i click (file-> close) everything is fine.

what happens is when you browse to a compatible inf i.e. Class: Display, the tool moves the .inf to where you run the tool. Thats why you see LV2GO.inf. When you click modify the tool mods the file and renames it back to the original file name.

When you click reset, or exit, the tool moves the .inf back to its original location with the file same file name as before without any mods.

yeah very weird why those drivers dont work with the control panel ???

Good to know its working on Vista x86 as you are the first to comment saying it works for that OS.
IF you install 275.27 and the control panel still doesnt show up let me know! thanks

Thank you very much for this tool.

Finally I could install the latest (275.27) drivers for my Acer Aspire 5935G notebook (with GT 240M and Intel Hybrid Graphics).
Using LV2GO++ 1.0 BETA even Optimus is working and seems to be fine.

Just a contribute.
I tried to mod the parallel insight 270.81 with the program. It installs fine (win7 x64) but nvidia control panel is nowhere to be found. Even if you launch it manually nothing happens.
In the context menu theres only nview if you decide to use it, otherwise nothing happens.
Maybe a bug?

Hi Dox,

Modded and installed 275.27. Works well with 32 bit Vista and my old GO 7950GTX.

Supports Nvidia Control Panel.

Did some comparative tests with GPU-Z logging, using the CoH Performance Test and both 270.80 and 275.27 run equally well for frame rates, and do it more efficiently (GPU temp, Mem usage, GPU load, Mem load), and better, than earlier drivers I've had installed, - even on this old Inspiron 9400.

Given 275.27 supports NV Control Panel, - I'll go with that new series I think.
