Blue screen when monitor inputs changed

Recommended Posts

10.5.5 Vanilla kernel with NVDarwin 1.1 installed for an 8600GT 256. I have a Benq G2400W connected to my hackintosh via DVI and to my Vista box via HDMI. Mouse and keyboard via KVM switch. Everythings working great with the only problem being:

 

When I use the monitor to change inputs (e.g. from DVI to HDMI and then back to DVI) the hackintosh shows a pale blue screen. I've had to resort to the mouse corner sleep display fix to overcome this.

 

Is there a proper fix for this so that the screen doesnt get stuck at blue? Or is this a known problem? Just wondering if there's a kext I'm missing or something I need to change in the gfx drivers to prevent this from happening.

 

Thanks.

I have the same problem whenever I try to change resolution...

even when you press esc to revert back between thte 15seconds it won't come back.

If you go to sleep and come back the display works again... strange

I also have the same problems. And it is exhausted the possibilities. I tried everything: EFI-Studio/String, NVinject, NVinstaller, NVkushInstaller, XDarwin, ... ... That last (XDarwin) that it was great results, as well as EFI inject.

 

As for NVCAP, I can not believe that this is really the problem. Right after I have installed Windows only to extract the ROM (NVFlash), the problem still persists!

I have a blue screen when i change display resolution. When I try "OpenGL Extensions Viewer" application and set another resolution\frequency for test (for example 1280*1024 60hz and not in fullscreen mode) - it's works (see the size of window, original resolution was 1024*786 75 hz). But when i select "fullscreen mode" for test.....i have a black screen (like i have when starts games like zuma and others, where resolution also changes for play). reset....

 

what the problem?

Exactly! The boot option "-f" recreate the system Mac extensions cache. What are those files that the hackers guide us to exclude (/System/Library/Extensions.mkext and /System/Library/Extensions/Caches/com.apple.kext.info) to reflect changes in the injectors / EFI-String.

    • Good evening to all. So, I have an external 1TB seagate HD and it always reads normally, but now when I plug it into my HACK it just does not read, it does not even appear on the disk utility. The light always turns blue from the HD without blinking. However I plugged it into windows, on a macbook and it worked normally. I already formatted my hack but it did not work. Thank you in advance for the help and sorry my bad english   my kexts: AppleALC.kext FakeSMC.kext IntelGraphicsFixup.kext IntelMausiEthernet.kext Lilu.kext WhateverGreen.kext VoodooHDA.kext USBInjectAll.kext NvidiaGraphicsFixup.kext   GTX 1080 Windforce core i5 7º generation 8gb Ram H170M Plus BR    
    • WOL packet is reaching the machine from LAN and from WAN (set with port forwarding), tested with "nc -l -u 9".
    • For me the forum seems reasonably OK, except whenever I see the word 'LOADING' - like when clicking another page of a thread - when it just stops completely and never returns.   I use an adblocker, so adverts aren't slowing me down.  Browsing the forum indexes is not too bad, as is clicking to view any thread.  Ditto clicking a link in an email notification to go to a particular post in a thread.  Sometimes it takes maybe five seconds to load a page, which is a bit too long.  But it's not terrible.   But then whenever I click on any other thread page, which tries to do the in-page content load (without a full page refresh), I see LOADING and then nothing further happens, even after minutes.   It's definitely not related to which content is loaded, but rather how it is loaded.  For example if I go to the index for this forum, then click directly to page 11 of this thread, it loads in 1-5 seconds.  But if I click the link to page 11 within the thread, it never comes back.  I just see this, forever:     This stuck issue seems to me likely something broken (code or configuration?) rather than a general slowdown.  But maybe there's also a general slowdown, especially for those who are seeing adverts.
    • This is as far as I can get with the AMD kexts and the device ID added. They load but the frame buffer isn't loaded. I've tried loading all 7 frame buffers included in the X1000 kext with no luck. From the tests Gigamaxx did there seems to be more luck spoofing as Intel graphics there. More support may come from integrated Vega though, hard to tell.    
    • as documented here it is a sample rate standard and i have also tested it and i can confirm that it works with my audigy rx at least, i have to test it with other cards   https://github.com/audiojs/sample-rate
