Cannot start Firefox Gtk-WARNING **: cannot open display:
Last modified: 2005-09-07 17:41:45 UTC
I used update instead of install, but this is probably not important, from beta 3 to beta 4 plus and when I run Firefox it writes: DISPLAY empty or unusable. DISPLAY=:0.0 After exporting DISPLAY=localhost:0.0 it writes: Gtk-WARNING **: cannot open display:. Other aplications like Mozilla, OOo,... are without problems. Attaching strace.

Well what is the value of DISPLAY in your environment? Are you starting firefox from the command line?
As I wrote: echo $DISPLAY DISPLAY=:0.0 I was wondering that Firefox doesn't starts, so I ran it from commandline and it wrote to xterm: DISPLAY empty or unusable. DISPLAY=:0.0 This is default also in previous betas. Exporting DISPLAY=localhost:0.0 was probably wrong, so "Gtk-WARNING **: cannot open display:" is IMHO correct behavior. So the attached strace is probalbly useless, I'll attach a new one.
Created attachment 49098 [details] correct strace output Ignore the first one.
