Do you have any idea if your xlr8 G4 upgrades are compatilbie with the the upcoming release of Leopard? The news says you need at least 867MHz to install. After your upgrade I easily make that but if the installer looks at the machine ID it might think I am below that magic number.

| I'll let you know. I'm going to try it early next week on my 700 MHz flat panel that was upgraded to 1.35 MHz a couple of years ago. I'm going to uninstall XLR8 software first just as a precaution.

| Also no joy - got the "Leopard cannot be installed on this computer" msg. Going to try a back door approach when I get time - will try cloning the Leopard system installed on my laptop to the flat-panel iMac's hard drive via SuperDuper.

The installer looks at the version of the system and speed. This can create two issues on an upgrade. The first being that the version is not changed (ie, ID=imac=bad), the second being that the CPU used in the upgrade may not be recognized by the profiler and may not be recorded correctly (sped wise) for the installer.
One way around it? Put the system in firewire mode and install from another system.
Another way is to order Leopard with a DVD backup patched for 100MHz G4 and up from the link below:

Finally got around to trying the SuperDuper clone method of installing Leopard. Didn't work. Gary's suggestion of putting the upgraded G4 In Firewire mode and installing from another computer (my G4 iBook in this case) did work.
Leopard runs fine, but there is a problem with Sleep mode on the iMac. Neither the display nor the computer will Sleep with the Energy Saver settings. If the screen saver is running, it just freezes when the display sleep is scheduled. Even worse, if you do put the machine to sleep via the Apple menu or Power Button, when you wake it up again, the display is garbage (just a bunch of colored thin vertical lines). Have to reboot at this point. By the way, this happens with or without the XLR8 software installed.
Unfortunately I didn't test Sleep right after I did a clean Leopard install and before using Migration Assistant to pull over all my stuff from my new Intel iMac. Maybe some of this stuff messed up my G4 iMac. If I get really ambitious and the weather is too bad for golf, I might start over and check this out.

After some diligent searching in the Apple support discussions, I found a thread that exactly describes the sleep and video problems I'm having. It's common to flat-panel iMacs running Leopard and can be fixed by removing the Leopard video drivers and reinstalling the Tiger ones. (Fairly complex task in Terminal mode.)

Unfortunately, the fix also disables Quartz Extreme graphics acceleration, which leopard relies upon heavily. Since the cure seems to be worse than the disease, I think I'll just live with my i(insomniac)Mac.
