Switched to desktop 4, Started Steam, mouse cursor changed to Steam cursor, system froze solid. CapsLock, NumLock, mouse cursor, ctrl-alt-del, and ctrl-alt-F1 all did nothing. Fan speed did not change. (I have never seen this before in more than a decade of TDE and Steam.)
Hi Mike, not excluding a TDE or TDE-triggered bug, but the fact that even ctrl-alt-F1 didn't work may indicate some other problem. Also since the fan speed didn't change, it seems it was not something going into some sort of infinite loop. I don't use Steam, so I have no experience/comparison in that field. If it happens again, could you try to ssh into the machine and see if it is usable from there? or it is instead a total kernel panic? or X becoming frozen? Whatever info you can collect may help.
