#58 Notion freezes when using selenium testing

Drake Douay

I am running notion on Ubuntu 12.10, and Firefox 18.0.1. I use tmux, bash and xterm in case it matters. The bug occurs I run selenium-server 2.29.0, and run acceptance testing. After the testing is complete Notion no longer works. Everything looks normal except none of my frames are highlighted, and I cannot find any combination of keystrokes to active any of the windows. Also F12 no longer works so I cannot, logout or restart notion.

The testing I am running is Yii's default acceptance tests, specifically the file in protected/tests/functional/SiteTest.php. I use phpunit to run it.

In order to regain control I need to press CTRL-ALT-F1 and pkill firefox. After I do that one of my frames becomes active and everything returns to normal. If I instead pkill java, then I will need to close notion to regain control. pkilling firefox when java is not running will have no effect.

Please let me know if there is any of details you need.

    Interesting! This sounds like something I sometimes run into but have been unable to reliably reproduce.

    To verify this is the same thing, can you verify:
    * You can still move the mouse pointer around
    * The pointer still changes shape properly when it hovers different kinds of windows
    * When you change the windows (e.g., hit f2 to fill a frame that previously held Firefox with an xterm), the mouse pointer suggests indeed firefox was replaced by an xterm (the mouse pointer becomes a caret instead of an arrow), but firefox is still what's visible on the screen

    Are you using the nouveau display drivers?

    I can still move the mouse, and the pointer changes shape. It appears the problem is a background process is now active and it doesn't release control.

    F2 does not work.

    Also for some reason the problem is not being reporduced as consistently as before. Now I need to run the test multiple times before it freezes. I am going to reboot and see if I can make this bug more reliable :-)

    What you are talking about sounds very similiar, but I suspect they may be different.

    I am not sure which display drivers I am using. Here is what lshw says.

    I haven't seen this problem for a while. Are you still experiencing it?
