2x dell 9400 10.5.7 & 10.5.8 wired issue with graphics (freezes and artifacts)

[turdor]

Hellow everybody and have a good holidays!!!

 

If anyone can help please:

I have 2 dells 9400:

1. C2D 2ghz, 2GB, GF7900GSgo, A09 bios, iAtkos 10.5.7 voodoo -> 10.5.8 apple online upgrade (not voodoo?)

2. CD 2.16ghz, 2GB, GF7800, A10 bios, iAtkos 10.5.7 voodoo

 

In both cases I used nenitosoyyo's (THANX MAN!) guide:

with one difference, I addad "post install actions" from iAtkos list (the very last tick), and used his modified GF kext for 7900 from same topic and used synth's (THANX 2U2!!!) modified 7800 kext for second dell:

EVERYTHING working perfect, including 2cores without patch, all sleep(50/50)/rstrt/shtdwn, sound, QE, CI, Rotation, QGL(buggy), DualScreen (VGA) etc. (didn't test FireWire and SD/PCexpressCard, DVI, Svideo)

BUT:

 

on both machines I have very same graphical issue:

everything is ok until I'm lunching photoshop for instance: as soon as I'm trying to use some tool (crop or gradient for instance) ALL the screen are freezing! Mouse is moving, and system is working (I can shotdown or trig the volume). It stays like this for about a minute or few, and then (in the middle) somthing could happen to mouse (it reverses and speeds up), then everything becoming alive, but w. artifacts and noise and some effect similar to when there is no video kext installed (moving of windows are not good - transparency+shadows acting wired). Same happening when I'm trying to watch DVD w. apple DVD player, and in Toast when trying to preview Video_ts folder b4 burning, but w. VLC everything is OK. Adobe Illustrator is OK, Premiere looks OK...

 

It's seems to be the same, when QGL is forced to be ON w. OSXtools and I'm lunching even Safari or any browser, but not shure.

 

Any Ideas?

 

Btw. - there is almost all kext's and ways not supporting QE as stated in many posts including those I'm giving links to... But these 2 I'm using here do support QE...

 

Thanx in advance!

HAPPY NY AGAIN!!!!

 

P.S.

I posted same in dell9400 thread, but no answer for a week ((

Ugh. This is most definitely a graphics driver problem. Unfortunately when I googled I didn't find anything useful. I think you're just going to have to look into other possible drivers for your cards. Do a google search with your card models and other pertinent keywords to see what there is. Nvidia cards usually have decent support so there's a fair chance you'll get it working. Good luck!
