freddy333 Posted May 18, 2017 Report Share Posted May 18, 2017 On a new FreeBSD installation running xorg with xfce, after a fresh install, when attempting to run firefox from either root or a user account, firefox fails to start & returns this error - 'Error: GDK_BACKEND does not match available displays'. Obviously, a display problem of some type, but I am not clear on what to do about it? After extensive googling, I found a number of 'fixes' that suggest running some variation of - export DISPLAY=:0 But FreeBSD does not have an 'export' command, so this just produces a 'command not found' error. Anyone know how to fix this GDK_BACKEND error for firefox on FreeBSD or Linux? Link to comment Share on other sites More sharing options...
freddy333 Posted May 18, 2017 Author Report Share Posted May 18, 2017 Update - It was recommended that I try firefox-esr instead of the standard firefox, so I uninstalled firefox & tried firefox-esr & it worked. So please ignore this thread. Link to comment Share on other sites More sharing options...
