I still haven’t really traced the source of my scrambled Crux graphical systems — I’m hoping the Crux 2.5 release candidate sorts it out for me — but one thing that was mentioned to me in IRC was that an xorg-server 1.5.3 “bug” (“feature”?) causes both the keyboard and mouse to go dead if HAL isn’t running on the machine.
Of course, I run without HAL as a course of habit, so it didn’t surprise me when an Intrepid system I build up from nada had nada coming from the mouse and keyboard. A quick double-check of my personal desktop wiki, a sharp three-finger salute to regain control of my system, and with this line added to the “ServerLayout” option in my xorg.conf file,
Option "AllowEmptyInput" "false"
everything was right as rain. If, for some reason, you find yourself in the same boat, that might be what fixes it.
It’s worth mentioning that this didn’t solve my mangled X systems in Crux though. The solution to that problem is still out there somewhere. I want to believe.
