I have experimented similar to what was suggested. Like Mike, I now believe the problem has something to do with X. Here is what I tried. Instead of typing a boot command, I used the "type I to enter interactive mode" feature during boot. I tried this twice. One time I said "no" to starting avahi-daemon. The other time I said "no" to starting the first-time boot service. (I have noticed that that always runs, even when it is not the first boot after install. At least that's the case on my other FC5 machine.) Anyway, the results were: - not running the avahi-daemon didn't change anything. The system hung at the same point with the same blank grayish-blue screen. - not starting the first time boot service did let boot get past the avahi-daemon. However it did not fix the problem. It eventually did hang with a (mostly) blank grayish-blue screen that had junk in a narrow band across the top. Based on this, I am thinking the problem has something to do with X. The strange thing is that I have no problems with the same monitor and display settings when I use my other FC5 machine that has an nVidia nForce4 chipset. (That machine is still on the original kernel that came with the FC5 distro because of a dmraid bug, so it still has the original driver that came with the distro, not the updated nVidia driver.) OTOH, I am not seeing any reports of problems with the Intel chipset that is in this system. Also, this monitor has worked perfectly with FC4 and FC3. I am thinking that maybe my next step should be to go into rescue mode and try to see what the config file says about my video adaptor and monitor. It can't hurt. If that doesn't reveal the problem, I just may try reinstalling and see what happens if I don't change SELinux and don't change the monitor settings. Debbie P.S. I am going through a KVM switch to share the monitor among machines. That has not been an issue for FC3, FC4, or FC5 on my other Linux box.
