I'm sorry to bother ya'll with this seemingly newbie question but I've thus far been unable to find an answer. I've been researching whether or not it is possible to add a configurable button to GDM. A button that can be defined to execute whatever command string I'd like. I know that themes can be created to change the look & feel of GDM but I haven't been able to find out if it's possible to do what I'd like to do. To be more specific, we have systems on IP-based video switches. Sitting at one terminal I have access to a Linux host as well as a seperate physical Windows host. To switch between either computer on the same screens I execute a script that tells the video switch to change the feed. My main issue is currently I need to be logged in to perform the switch. That being said,
If I log out of the linux host I cannot switch to the windows host without logging back in and thus leaving my linux session open. I could however add the executable to PostSession but their may be an instance where one would just want to log out and not switch the video feed. To be honest I obviously have the same issue with the windows system and that basically means that there will always be one host logged in. So basically I'm looking for a bit more flexibility on the linux side rather than forcing a switch on logout. The more I think about it, the more PostSession makes sense, however the question still stands.
Thanks. :)
