<div dir="ltr"><div><div><div>Vaclav,<br><br></div> Thank you for your response, it is very helpful! So, the upshot is that the current version packaged for Ubuntu in the PPA has the broken g.version, which somehow prevents the GUI from rendering. This is just in the PPA version, but the compiled version *should* be fine. So my current options are to roll back to an earlier version, compile the current version from source, or to run GRASS headless for the moment (no issue for me) until the problem is fixed (I assume at least by when 7.0 stable is released?).<br><br></div>Also, thanks for letting me know about g.mremove. I didn't know about that! I am currently porting some of my addon modules to 7, so I will change their map clean up routines to use the new functionality of g.remove. Goes to show that I ought to pay more attention to the roadmap!<br><br></div>~Isaac<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Nov 19, 2014 at 7:52 PM, Vaclav Petras <span dir="ltr"><<a href="mailto:wenzeslaus@gmail.com" target="_blank">wenzeslaus@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Wed, Nov 19, 2014 at 7:36 PM, Isaac Ullah <span dir="ltr"><<a href="mailto:isaac.ullah@asu.edu" target="_blank">isaac.ullah@asu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><div><div><div>Sorry, premature send!
