I'm replying to this thread . . . to myself or my last post in this thread, because this thread had dropped to page 4 and the problem as I described with the reviving from suspend issues . . . continues. It is not a total failure to revive, most times I get the log in window, I can log back in, the desktop is "populated" but clicking on tabs or on icons does nothing . . . only option at that point is to shut the unit down, this happens about 6 times in ten attempts to wake from suspend.
This is the rsavge version of Xubuntu 12.04 for PPC on iBook 933 MHz with 640 RAM, and I added the LXDE DE, which brings a non-working Openbox. I might have had Lu 12.04 loaded before, and probably the suspend issue was a problem there, in this version sometimes it works but many times it doesn't. Any thoughts appreciated, perhaps removing the LXDE DE?
