XORG freezes machine in Firefox right after boot

I'm running Ubuntu Intrepid on a Dell laptop. I turn it off at night.

Every morning when I turn it back on and open Firefox, I have to wait while the machine is busy/freezes for maybe a minute. This usually happens twice, but sometimes three times. The processor light is on solid when it does this.

I've run TOP from the terminal, and it says it's XORG that's running.

This only happens when Firefox is running, and when I first turn on the laptop after it being turned off for a while. Every morning, when I first run Firefox, XORG takes control of the laptop. Not a big deal, but frustrating and worrisome.

Is this normal? Is it supposed to do this? It is a little irritating.

There is no processor light in any notebook computer. There is a hard drive light that you might be describing. Your problem could be slocate updating its database. If you turn off your computer before cron runs the utility to update slocate, there will be a slow down when the utility is running. Also Linux will always be slow for the first few hours of use, so it is best to leave it on. Linux will cache and buffer the data, so problems like this does not come up. If your setup is set at ondemand for its processor governor, the performance will suffer even more. It is best to have it at performance unless you are on battery.

Distributions like Ubuntu sets the kernel in preemptive mode which is OK for most desktops, but costs performance problems when a program requires too much resources. I set my kernels to voluntary preemptive, so it does things softer during preemptive mode than setting the kernel to just preemptive.
