The night actually started out clear, but with the moon up, we started with specoscopy: Cart 1 plate 627. Right after opening the building, we went to move the telescope up and found the MCP unresponsive - we could not even connect to it via telnet. We rebooted it and all was well. Today, Dan is driving on his machine while Scot is operating Landru in multi-screen mode, but with a DIFFERENT Xserver than previously. Earlier in the evening, he got the old Xserver to die within 10 minutes of logging in. The new Xserver runs a different instance of the window manager in each screen and does not allow for dragging of windows across screens. But it does mean any window that pops up from another window will be on the same screen as the parent. We'll run with this and see if the X crashes go away. (Most of the time, btw, the "crashes" means the Xsession dies and we are returned to the Xdm login prompt - although more severe crashes have also been experienced. Cart 1 - plate 627 required a 15" E offset to find guide stars. We ware running with the 72 point pointing model. Dan recommends running with this model and applying a 15" E offset if you can't find stars. Last night, the same plate with the same pointing model found the stars right away. What'sup with that? We did reboot the MCP today, though.
