[Chimera-users] Incompatibility between --nogui and viewdock scripting ?

[Greg Couch]

Unfortunately, ViewDock, as one of the earliest chimera extensions, does 
not work in nogui mode.  I've added this as bug #7799 in our bug database. 
The only workaround would be to run chimera with the DISPLAY environment 
variable set to a virtual X server, like Xvnc.

 	Sorry about that,

 	Greg
