Re: [linuxtools-dev] Hudson job hanging on AllTmfUITests

[Alexandre Montplaisir <alexmonthy@xxxxxxxxxxxx>]

Hi Roland,

When we run tmf.ui tests locally, it opens a separate Eclipse window in
which some UI functionality is tested (mainly for the Sequence Diagram
framework). Looking at the Hudson log, it ends on:

Xlib: extension "RANDR" missing on display ":108.0".

What I assume is happening is that the test tries to open an Eclipse
window, but either there is no X server on the Hudson VM, or there is
one but XRandR is not supported. I guess it's the latter, because there
seem to be 108 displays running already...

This is strange, because we've had these tests for a while (at least 6
months). Did the Hudson configuration change recently?

Would you prefer if we disabled the Sequence Diagram tests until we sort
it out?


Cheers,
Alexandre
