Hello folks, I have a little problem that make me work on Windows... I upgraded my machine with a new graphic card GeForce 6800 Pro. I bought this one because i wanted a nvidia card for its compatibility with linux, and i've heard that the drivers works pretty well. I've updated KDE though yum, there were compatibility problem, so i had to update arts, after kdemultimedia and after kde base. It install as well the new kernel. I've added lvnia to my depo repository and install the nvida drivers. I was pretty happy, because i saw the nvidia screen and i was able to have a beautiful resolution. At this moment the computer froze (around 2 minutes) , i thought it was only kde who was f**** everything. But i could not kill X. I went to my laptop and try to connect to my computer to see what happen (dmesg), but the computer did not reply. I tried to ping and anything came back... Any ideas, i m running a AMD Althlon 64 X2 Dual core 4600+ with 3 Go of ram. Thanks for the help -- Franck
