Updating from 10.5.2 to 10.5.5 video problems

[Winters]

Just installed and updated my Zephyroth 10.5.2 to 10.5.5. I had a bit of a problem when it restarted since there was no video output and the screen went to sleep mode. I restarted it second time with -v option and it was ok. Now when restarting it, I have the same problem. Do you have any suggestions?

When updating a Hacintosh, sometimes the video and audio "fixes" get "undone" or rather, revert back to their original state before the issue was fixed. You should restart using -x to enter safe mode so the video kernel extensions aren't loaded, then reinstall your video. Make sure if you are injecting kext files that they have the correct permissions... now you should be all set.

Hi nfoav8or!

Thanks for your reply! I did try to inject the video ktexts from Nvinject 0.2.0 which have previously worked with my GC but no success..I can still boot to Leopard but it just takes me a solid 3 to 4 minutes in which the screen goes into sleep mode..Anyway, Zephyroth Update utility works great and now I'm using 10.5.5. The delay in booting is no major deal..Thanks for your reply and my congrats to Zephyroth on the great utility. I used it to download and modify the pkgs and then installed them manually. The interface is clean and simple, much like Apple's UI. Keep up the good work!

hmmm. ok.. a few more helpful tips then...

NVinject 0.2.0 is an old injector. get the newest ones from http://nvinject.free.fr/downloads.php.

also, make sure you check the permissions of the kernel extensions that were just placed in the Extensions folder by running in Terminal:

sudo chmod -R 755 /System/Library/Extensions/ && sudo chown -R root:wheel /System/Library/Extensions/

or do what I do upon rebooting is to boot using the kernel flag -s and then

/sbin/mount -uw /
cd /System/Library/Extensions/
chmod -R 755 * && chown -R root:wheel *
cd ..
rm -Rf Extensions.mkext
reboot

This will force the individual extensions to be separately loaded and make sure they have the proper permissions. (same thing as running permission fix in Terminal and booting with -f)


EDIT: have you thought of trying EFI out?

Hei there!

Thanks for your tips. I did as you said but no deal. I even used the nvinject installer and fixed the permissions with disk utility but nope..I have been reading around and it seems that not even the newest version of Nvinject is working. Maybe I ll just wait a bit longer to see if new drivers come up..I had thought about EFI but then again I would rather save up the money and buy a real Mac, which will happen sooner or later! But really..thanks for ur help and time! You and all the guys here at InfiniteMac!

before you give up on EFI, search through the forum and have a look at some of the posts regarding it. EFI is a good way to make your card work natively with the OS as it doesn't require an injector... its simply a hex string that gets placed in /Library/Preferences/SystemConfiguration/com.apple.Boot.plist.




EDIT: I moved the posts to a new thread so it doesn't get too far of topic in the old one.
