Yesterday I installed F10 onto a spare disk. I installed over the network with my LCD monitor (Samsung 240T) connected to the DVI output of my onboard graphics card (ATI X1250). As soon as the initial tftp messages had finished and the fedora installer started (with the "network manager is configuring eth0" message), the display began flashing on and off. I was using kickstart with vnc on, so I switched off the monitor and let it complete the installation. However booting the installed system has the same result. Everything is stable until the point where plymouth starts (or the alternative text output if rhgb is removed from the boot line), when the display begins flashing again. This continues after the X display is started, using Vesa or Radion (fglrx results in an immediate reboot, but that's another issue). If I switch to the VGA output then the display is stable, but offset to the left by about 40 characters. If I boot back into F8 then everything is stable, so I'm sure it's not a hardware problem. Has anyone seen this or have any suggestions how to fix it?
