#1
Updated by Alexandre Quessy about 3 years ago

  • Status changed from New to In Progress

I already check if the os.environ has a key called "DISPLAY". Should be use xdpyinfo to see if the display exists? Otherwise, should we just see if it matches :[0-10].[0-10] ?

#2
Updated by Alexandre Quessy about 3 years ago

I think we should use some GTK mechanism to check that.

Something like GDK_IS_SCREEN (screen)

#3
Updated by Alexandre Quessy about 3 years ago

  • Status changed from In Progress to Closed
  • Resolution set to fixed

Done in r5741.

GTK rocks.
