I upgraded to Fedora Core 7 this weekend and I'm now experiencing the same behaviour. I've also experienced several X crashes since the update
X takes 100% of the CPU. I'm running on an ASUS A6000 Laptop with a dual AMD64 CPU.
My GPU is
(--) PCI: (0:10:3) nVidia Corporation MCP51 PMU rev 163, Mem @ 0xdcec0000/18
(--) PCI:*(2:0:0) nVidia Corporation G70 [GeForce Go 7600] rev 161, Mem @ 0xde000000/24, 0xc0000000/28, 0xdd000000/24, I/O @ 0xdc00/7, BIOS @ 0xdf6e0000/17
My X.org version is xorg-x11-server 188.8.131.52-9.fc7
My NVIDIA driver version is NVIDIA-Linux-x86_64-100.14.09
I'm not running VMWare
If i can provide more useful information, let me know !
