[Solved] Please help! GPU not working after upgrade to 13.1

[Pepperish]

Yes that looks right. From what i can see there isn't anything that should stop the graphics from working. Have you tried different outputs / ports?

Do you think I should use profile 17,1 instead of 14,2?
Then the fix from the pinned post can work it’s magic

i just shot a small video about what i did to restart, and also the bios settings. you may have a look if you want.

One thing you might try in BIOS settings is experimenting with CSM video versus UEFI GOP. How to do this may not be obvious, but it may be linked to 'Windows features' or 'PCI Op-Rom' settings. Just make sure 'Fast boot' remains disabled if you change another setting.

If you try that install Lilu.kext + NvidiaGraphicsFixup.kext - iMac17,1 related black screen issue is likely different from your present problem (monitor may show 'no signal' or similar)

Also booting with a single monitor attached and trying as many different ports as possible may help, if you can get output working then try attaching a second monitor (screens may go dark again, or maybe not)

hmm, an interesting thing happened. i just got home and start trying to pick up where i left off yesterday. and it boots properly in to the system with nvdia card activated.
i am positive that i have not done anything after yesterday.
do you wanna check something to see what is changed?

No need, you should be good. Once you get a working display configuration written (to where exactly who knows?) it should 'just work.'

everybody else got to the point with ease.....

Not true these drivers have been a lot of trouble on 10.13.x for many users. Anyway good news, you can hopefully finish your post-install with working graphics.

Please upload your current Clover folder zipped minus themes. Thanks.

Pepperish, did you solve this problem? I am still working on a very similar issue.

Pepperish, did you solve this problem? I am still working on a very similar issue.

i didn't technically "solved" the problem, as i said in #23, it just magically turned from not working to working overnight.

i would suggest you to follow what i have done in the posts, based on my understanding, i have done almost everything out there

the theory is that you need these things to make it work(sorry for the amateur terms, i can just explain based on my understanding):

• you have nvram, which can be done here to store the changes you made to ask the bootloader to remember to turn on the Nvidia card. to do that you need the "Install RC scripts on target volume" and "EmuVariableUefi-64" from Clover bootloader
• the you need to configure the bootloader again to remember triggering the Nvidia driver everytime, by setting NvidiaWeb = true in 10.13.1
  
• then you install the latest driver, and make sure it matches the correct macOS version, and restart by selecting the "Nvidia Web Driver" instead of "OS X Default graphic driver"

i figure these are all that you need to get them
but if you are using system profile later than 14,2 you need to patch with lilu and NvidiaGraphicsFixup, but with 14,2 you dont need them

these are basically the summary of my study these days, hope this can help

I have been so frustrated with this, that as a last resort, I tried a re-update of high sierra, and remarkably, that worked. When it rebooted, the Nvidia web drivers worked. That took me a couple of weeks to fix, and I will probably never know what I screwed up. Thanks to everyone in the forum for everything you do.
