Unity8: All apps fail to start

[Daniel van Vugt]

I haven't done much testing of Unity8 since before I went on vacation last year, but now I look at it again all Qt apps in the dash fail to start. They just flash up a window briefly and then go away. The same failure does not happen with native Mir apps like Xmir or mir_demo_client_*

Here are the logs from the failures of Browser and System Settings:

Any chance it's either of bug #1513266, bug #1535058 ? Is cgmanager running? Do you have libpam-cgm installed?

[Daniel van Vugt (vanvugt)]

Almost certainly it's one of those. And those two are possibly the same bug.

Confirmed I'm experiencing bug 1535058.
