[HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R17.1\ACAD-6001:409\FixedProfile\Application Window] "Position"="178 61 1483 874" "Show"=dword:00000001 [HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R17.1\ACAD-6001:409\Profiles\<<Unnamed Profile>>\Drawing Window] "MoreHideWarningDialogs"=dword:00000200 These are the keys, the firs one is to avoid a small window that sometimes causes autocad to crash, change acording to your resolution The other simply hides the "what's new" thing.

I'm using a build from here http://mike.kronenberg.org/ I don't know why using this build all is smooth and without crashes (I guess the libraries he includes are the solution). I tried to include some of the libs in my own build but with no success. I don't know how would be on Ubuntu, I'm sorry.
