Re: Display issues with 9600GT AGP
I had the same exact problem with my 7300 GT AGP card.
I used to get visual artifacts in some opengl windows that led to system freezes. switching to tty would prevent the system freeze and temporally stop the artifacts but a reboot was eventually needed.
Later I found out that there is a power connector slot on the nvidia card. I turned off the PC, attached the power connector slot to the case's PSU and the visual artifacts and system freezes stopped. I hope this helps
