jdazzle34 Posted April 23, 2012 Share Posted April 23, 2012 So I made the silly decision this weekend to upgrade from Snow Leopard to Lion because I'd read in a couple places that Lion had cured the infamous Fermi Freeze. I installed Lion and had a mostly incident-free installation, but I have had 0 luck with my GTS 450 (a 1024MB Galaxy GTS 450, if it matters). I have spent the past 24 hours digging through the forums, looking for a solution. I've tried npci boot flags, the official nVidia drivers, editing AGPM and NVDAGF100HAL with my device ID. I even tried an EFI string for my card. The best scenario I've gotten to is having my card recognized by the system, but I have no acceleration and no resolution control. I have a Dell 3007, and even if i set the display mode to 2560x1600x32 at boot, I only get 1600x1200 resolution. The system lists my display as spdisplays_display. My apologies if this topic's been covered, but for the life of me, I couldn't find any more suggestions beyond those I've listed. If it helps, my motherboard is a GA-P55-USB3 Rev.2. Everything else seems to be chugging along fine, but I'm having zero luck with the 450. Thanks in advance for the help. Link to comment Share on other sites More sharing options...
