Hello, I've installed FC5, and I'm running X (KDE) without any problem. Yesterday, I decided to migrate up to 2.6.16.11, and also tried 2.6.17-rc3. So, I downloaded kernel from kernel.org, built it, applied the 'udev migration' procedure (as I'm not using initrd with vanilla kernels), and restarted the machine. Good news, it is running fine, except that X doesn't work anymore... It does start, I can 'hear' it changing the resolution (I have a CRT not an LCD screen), but the screen stays black, no cursor, and X goes eating 100% of the CPU, being unkillable (though the machine can still be used, I can network-connect without problem except latencies...). Checking /var/log/messages, I can find : May 1 19:09:38 riri kernel: agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0. May 1 19:09:38 riri kernel: agpgart: Badness. Don't know which AGP mode to set. [bridge_agpstat:1f000a0a vga_agpstat:ff00021b fell back to:- bridge_agpstat:1f000208 vga_agpstat:ff00021b] May 1 19:09:38 riri kernel: agpgart: Bridge couldn't do AGP x4.

Before running FC5, I was an FC4 user, and I was also running a vanilla kernel with X without such a problem... Who should I blame for X not working ? Kernel, as it is the one part I changed, or X, as this was running fine before with the X from FC4 ? lspci says : 00:00.0 Host bridge: VIA Technologies, Inc.
