mterry | RAOF: you there? Did you ever dig into Mir and VT switching? | 12:00 |
---|---|---|
RAOF | mterry: Yes; we want you to enable a Mir report and reproduce the bug. | 12:01 |
mterry | RAOF: can do | 12:01 |
mterry | RAOF: which report? | 12:01 |
mterry | RAOF: you think it's Mir's fault after all then? | 12:01 |
RAOF | mterry: No. | 12:01 |
RAOF | mterry: MIR_SERVER_DISPLAY_REPORT=log is your winner, I belive. | 12:02 |
mterry | Dang it, it would have been easier if it was Mir's fault | 12:02 |
mterry | RAOF: ok will do that | 12:02 |
RAOF | mterry: The hypothesis is that Mir fails to drop master for whatever reason, which results in it (correctly) NAKing the VT switch. | 12:02 |
RAOF | (We call drmDropMaster, but that can fail; if it does, we throw an exception, (silently) catch it, and NAK the VT switch) | 12:03 |

mterry | RAOF: http://paste.ubuntu.com/23348320 -- I set the env, but don't see much about display output, doesn't seem like a useful log | 12:51 |
mterry | RAOF: I assigned this bug to you (but just as a point of contact, please re-assign or unassign as you see fit): https://bugs.launchpad.net/ubuntu/+source/mir/+bug/1634888 | 13:10 |
ubot5` | Ubuntu bug 1634888 in mir (Ubuntu) "Problems switching VTs" [Undecided,New] | 13:10 |
RAOF | mterry: OK. | 13:17 |
mterry | RAOF: if it is drmDropMaster mysteriously failing, is that a driver bug? | 13:17 |
RAOF | mterry: So, that shows that Mir is successfully calling drmDropMaster(), which means that it's probably someone else's bug. | 13:18 |
mterry | RAOF: you mean there's a lack of an error message? :) | 13:19 |
RAOF | Yes :) | 13:19 |
RAOF | It would say failed to drop master :) | 13:19 |
mterry | I guess I'll go back to robert and see if he thinks lightdm could be botching the hand off | 13:22 |
