Try moving video kexts in single user (press space bar in Clover) and boot without caches

After patching kexts as artur-pt suggested you can install them back.

If it does not work you can try this app in startup items

work with this option

but how to install back graphics driver ??

[pernacabeluda]

Patch kexts as in the topic from artur-pt and install using Kext Wizard (they are in /kext_backup).

if i install back it will white screen again ?

i don't see anything in kext_backup

its empty

If you run the commands from the first link I posted, they should be there.

Maybe the white screen gets fixed by patching the kexts, if it doesn't, try the FBRotate.app I posted.

I'v been told this white screen problem is fixed in Mavericks.

maybe i wrong type in command..

waiting to finish downloading OS X Mavericks 10.9 bootable USB for Intel PCs
