The key is that you do see a good display for a split second. This means that your monitor is still good, but your software is telling it to do something which is not conducive to providing a good display. This means that your monitor is probably OK. Here's how you can tell if your monitor was damaged by XFree86. Pull the horizontal output transistor, and check the CE junction in both directions. If there is a dead short, the clicking is caused by the power supply shutting off its over current contactor when it cannot source the shorted load. You can replace the dead HOT, but I would recommend buying a new monitor which includes protection circuitry that prevents junk software from drawing the flyback circuit off resonance and overheating the HOT. I have personally toasted 5 monitors with Linux, and 1 with Windows. __________________________________ Do you Yahoo!? New and Improved Yahoo!
