Hello,
I have installed the VirtualBox image 2012.12 and it is running quite well.
Many visualisations obtaine by the ‘core-metrics-results’ can be displayed correctly in the q2studio correctly, but the emperor style qzv visualisations are not displayed at all. The image displays only the emperor logo.
I have checked the the installed firefox has activeted WebGL, but does not solve the poblem.
If I download the qzv files to my windows pc, extract and look at it in Firepox, the emperor graphs are displayed correctly.
Any suggestion what I should edit in Ubuntu to get emperor plot running?
This is going to come down to where and how Electron (the backend of q2studio) handles its webkit browser. It sounds like something is funky with its WebGL. I remember playing around with emperor inside of q2studio (on a non-vbox installation) a while back and it worked fine. I think you may have run into this electron bug.
There's not much we can do about it at the moment I think. So I would stick with just looking at those visualizations in Firefox/q2view (or extracting like you've done, but that's more work )
Actually, is there anything you can tweak related to your graphics card configuration in VirtualBox? Maybe there’s some switch you could try flipping to see if that helps (as a total shot in the dark).
