Manual test /Testing resolution cycling for cedar[Radeon HD 7350] can not be executed properly

[Daniel Lin]

When running Manual test/Testing resolution cycling for cedar[Radeon HD 7350] on bDT Mordrad2,
plainbox take a picture a screenshot then keep running as attached picture. The process is never end.
Restart system and rerun test for 3 times, the situation is the same.
Can switch all resolutions manually without problem.

Could you please add the session data and plainbox logs as well?

The log files are in ~/.cache/plainbox/logs
The sessions are in ~/.cache/plainbox/sessions/

In case there are multiple sessions please archive all, I can figure out which are relevant. If the data there is not public, please change the bug to private / proprietary.

Hi, Please see the attachment.

Tested on 14.10 with the latest packages version (testing ppa W47), it runs properly from canonical-certification-client. So it's definitely not an issue with the command nor the script (rerun several times in the same session without any issue)

I'd suspect a deadlock duplicate as this script starts several sub processes to launch the xrandr and shutter commands.

[Zygmunt Krynicki (zyga)]

Sylvain: the deadlock issue affects all clients the same way. The only way to trigger it is to run a job that spawns *escaping* processes and IIRC xrandr and shutter don't do that. I don't think this is a dupe of that other bug.

possible dup of https://bugs.launchpad.net/checkbox/+bug/1382321

[Maciej Kisielewski (kissiel)]

I wasn't able to reproduce that one on my machines ( 14.04 and 14.10). I tried both, GUI and CLI front-ends.

[Zygmunt Krynicki (zyga)]

According to the attached session, the test that was being executed is 2013.com.canonical.certification::usb/insert. It's either a bad session or the test is invalid.

[Zygmunt Krynicki (zyga)]

Dear reporter, could you please ping us in #checkbox during Taiwan/Europe overlap and work with us interactively to investigate the issue.

What I'd like to know is:
- which job exactly triggers this behavior
- can it be reproduced with 'plainbox run -i ...'
- can we get access to the machine that can reproduce this issue

[Zygmunt Krynicki (zyga)]

This is a possible duplicate of https://bugs.launchpad.net/checkbox/+bug/1382321 as it seems to cover the same area (xrandr resolution switching)

[Zygmunt Krynicki (zyga)]

Hey. Since we also take a screenshot here I'm 90% sure it's caused by ~/.config/autostart being root-owned.

[Zygmunt Krynicki (zyga)]

I'm marking it as duplicate based on:

11:13 < zyga> danielyhlin: hey
11:13 < zyga> danielyhlin: no need
11:13 < zyga> danielyhlin: I want to check if that's a duplicate of an existing bug
11:13 < zyga> danielyhlin: can you check (if possible) on that system, if ~/.config/autostart is a directory owned by root?
11:15 < zyga> danielyhlin: if you need to reimage the system that test is hard to do :)
11:16 < danielyhlin> zyga, the machine is beside me
11:16 < danielyhlin> zyga, wait for me later
11:17 < zyga> danielyhlin: excellent, thank you
11:17 < zyga> danielyhlin: if that directory is NOT there, can you please give me remote access overnight?
11:17 < zyga> danielyhlin: (I've sent an email out with instructions yesterday, perhaps you've seen it?)
11:22 < danielyhlin> Hi zyga ~/.config/autostart is a directory owned by root? == > YES!!
11:27 < danielyhlin> zyga, whic email you sent out?could you send to me again?
11:28 < danielyhlin> zyga, the mail I found it.
11:28 < zyga> danielyhlin: thanks, sorry for the delay
11:28 < zyga> danielyhlin: ok, thanks
11:28 < zyga> danielyhlin: I'll mark that bug as a duplicate now
11:28 < zyga> danielyhlin: thanks for checking it
