[Touch-packages] [Bug 1673215] Re: Second unity8 user session hangs with a black screen
We could theoretically make the one USC instance appear (differently) on multiple VTs. In tinkering with Mir's VT code I came to realize that VTs are truly a virtual concept. If you ignore the existence of VTs then you can still forcefully start up your system compositor on the screen. Cooperating with the notion of a current VT is just being a good citizen.

[Touch-packages] [Bug 1673215] Re: Second unity8 user session hangs with a black screen
I filed the linked upstream bug. Lennart is on vacation for a couple more weeks, so this won't see quick action. pitti pointed me at old bug 1192842 which is basically an old dupe. All signs are pointing at this being an involved fix that will require upstream buy-in. So I'm inclined to set this aside for now and just accept the bug for zesty, rather than try to make big changes to logind late in the cycle; changes that we may not end up using in that form long term. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1673215 Title: Second unity8 user session hangs with a black screen Status in Canonical System Image: In Progress Status in systemd: Unknown Status in systemd package in Ubuntu: Incomplete Bug description: Login to user1 using u8 as the session login to a second session and select u8 as the session The screen goes black and the fan comes on indicating something is in a tight loop Waited for several minutes and it stays in that state.

I don't know of any other method other than to make logind allow this case as you've suggested. We cannot make Mir sessions runs on different VTs as that would make USC not work anymore.

[Touch-packages] [Bug 1673215] Re: Second unity8 user session hangs with a black screen
OK, more research. This looks to be a mismatch between what logind expects lightdm to do and what we actually do. Mir sessions started by lightdm all use the same VT number (they all live on the VT owned by unity-system-compositor. But logind does not allow two user sessions to be on the same VT. (It does allow greeter and user sessions to share one, which is why we didn't notice this bug when using unity8-greeter logging into a unity8 session.) The relevant logind check is listed below [1]. One fix would be to allow type=mir sessions to share a VT. But I'd like input from Robert Ancell before moving on that. It's possible lightdm should be doing something else or that we don't actually want to break the assumption in systemd that each session has its own VT. [1] /* * Old gdm and lightdm start the user-session on the same VT as * the greeter session. But they destroy the greeter session * after the user-session and want the user-session to take * over the VT. We need to support this for * backwards-compatibility, so make sure we allow new sessions * on a VT that a greeter is running on. Furthermore, to allow * re-logins, we have to allow a greeter to take over a used VT for * the exact same reasons. */ if (c != SESSION_GREETER && vtnr > 0 && vtnr < m->seat0->position_count && m->seat0->positions[vtnr] && m->seat0->positions[vtnr]->class != SESSION_GREETER) return sd_bus_error_setf(error, BUS_ERROR_SESSION_BUSY, "Already occupied by a session"); ** No longer affects: mir -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1673215 Title: Second unity8 user session hangs with a black screen Status in Canonical System Image: Triaged Status in systemd package in Ubuntu: Incomplete Status in unity8 package in Ubuntu: Triaged Bug description: Login to user1 using u8 as the session login to a second session and select u8 as the session The screen goes black and the fan comes on indicating something is in a tight loop Waited for several minutes and it stays in that state.

[Touch-packages] [Bug 1673215] Re: Second unity8 user session hangs with a black screen
Some research -- this is because XDG_RUNTIME_DIR is empty for the second user... Not sure why yet. You can see the message "QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-testuser'" in the log above. The default for the mir socket that unity8 creates is $XDG_RUNTIME_DIR/mir_socket, which resolves to "/mir_socket" which unity8 can't create, bailing. That env being empty is not tied to a specific user.

[Touch-packages] [Bug 1673215] Re: Second unity8 user session hangs with a black screen
I have a samsung also with Intel graphics. When I get a console login I see a number of upstart jobs running, the top one at around 16% cpu. Unity8-dash and dbus-daemon are also running as the second user. Unity8 is running as the first user only.

[Touch-packages] [Bug 1673215] Re: Second unity8 user session hangs with a black screen
I was able to log into two different users with unity8 simultaneously. So that's positive. Maybe this isn't an everybody thing. It might be a graphics driver issue? Like Mir can't handle it in some cases? Adding Mir task to see if that's a crazy thought. /me is running Dell XPS 13 (intel graphics) ** Also affects: mir (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1673215 Title: Second unity8 user session hangs with a black screen Status in Canonical System Image: Confirmed Status in mir package in Ubuntu: New Status in unity8 package in Ubuntu: New Bug description: Login to user1 using u8 as the session login to a second session and select u8 as the session The screen goes black and the fan comes on indicating something is in a tight loop Waited for several minutes and it stays in that state.
