I have been having a problem with Ubuntu 10.04 hanging on boot. Some times it hangs on the splash screen and sometimes I get to the desktop, but there is no panel, desktop icons or mouse cursor. If I hard reboot (hold the power button in until shut down) it will come on and work fine after that.
I do not not know if this could be related but Transmission stopped working about the same time. Tried reinstall already. The Transmission box pops up but not the add prompt. Weird I know.
I tried yesterday to update to 10.10 to see if this would fix it. The upgrade went fine. I elected to replace the config files that it asked about to see if that would over write and possibly fix it. Needless to say, I am lost now.
