Getting "webkit_server: cannot connect to X server" on CI

[bcardarella]

I've set the driver to :webkit_debug and here is the output:

~/jobs/app/workspace$ rspec spec/requests/invitation_spec.rb 
webkit_server: cannot connect to X server 
webkit_server: cannot connect to X server 
Fwebkit_server: cannot connect to X server 
webkit_server: cannot connect to X server 
F

Failures:

  1) Requesting an invitation with valid information
     Failure/Error: visit root_path
     Capybara::TimeoutError:
       timed out
     # ./spec/requests/invitation_spec.rb:5:in `block (2 levels) in <top (required)>'

Thoughts?

nm

@bcardarella what's nm? I am getting the same error on Jenkins (ubuntu box) and there isn't much on google or even debugging that helps much.

@cnicolaou nm = never mind

This issue was two months ago, I should have documented why it was a non-issue as I cannot recall why now. Sorry.

[constantine-nikolaou]

@bcardarella no worries, if by any chance you remember how you solved it, please let us know

@cnicolaou i'm also seeing that webkit_server: cannot connect to X server. did you track it down?

[constantine-nikolaou]

Yes @kylefritz, i was able to run jenkins smoothly after following the instructions here: http://stackoverflow.com/a/646947/449483 (xhost ...) before Jenkins is started.

thanks for the tip @cnicolaou. i'm trying to run as the default ubuntu account, so tired

$ export DISPLAY=:0.0
$ xhost +local:ubuntu

and got back

xhost: unable to open display ":0.0"

any ideas?

The way to make it work is:

Xvfb :1 -screen 0 1024x768x16 -nolisten inet6
export DISPLAY=localhost:1.0

I hope it will help somebody :)
