[Dx-packages] [Bug 1322769] Re: 14.04 LTS AMD64 Password/Keyboard Lockup after Unity Lock Timeout with VirtualBox VMs Running
This looks similar to this bug: https://bugs.launchpad.net/unity/+bug/1305586 However - I've found that another issue is that whatever application has held on to the cursor, you will end up typing your password directly into. Google Chrome and Chromium seem to be the two most popular culprits. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Symptom: When the Unity System Settings Lock Screen Settings activate, and I notice the screen has gone blank and locked, I re-activate the keyboard (usually left CRTL) and the 14.04 LTS Login Screen appears. In all cases the keyboard is locked out and non-responsive, I can click on the password box for my account and anything I type no longer appears. I have to select Switch Account option with the mouse to get a new login screen for my account and I can log in. In some cases both the keyboard and the mouse input is locked out and non-responsive. I can not select Switch Account and must power off the laptop which of course is dangerous for the file systems of both Windows VMs that are running and the host/14.04 LTS file system. I have already corrupted the Windows VM file systems and had to repair while testing this bug for repeatability. Both laptops run the AMD64 version of Ubuntu 14.04 LTS. Both have built in Intel Integrated Graphics, one laptop with the older Ironlake, one with the newer ivy bridge. Both are running Oracle VirtualBox but different version: 1. Home is running the Ubuntu 14.04 Repository version of Oracle VirtualBox (Currently 4.3.10_Ubuntu r93012) 2. Work is running the Oracle downloadable AMD64 version of Oracle VirtualBox Currently 4.3.12 3. Both have the respective Oracle Virtual Box Extensions installed for 4.3.10 and 4.3.12 3. Both are running Windows 7 64 VMs Both 14.04 LTS have the following System Settings for Lock Screen: Brightness slider - All the way left Dim screen to save power - Checked Lock - Switch to ON position Lock Screen after: 5 minutes Require my password when weking form suspend - Checked I have tested this with both a VM running (no other running applications were tested) and with no apps running (fresh boot and login into 14.04 LTS unity desktops). 1. On fresh boot with no apps running the lock screen activates (after 5 min of no activity) and when I re-activate the laptops (usually pressing left CTRL on keyboard) I get the login screen and can enter my password successfully and the Unity desktop is presented. 2. On fresh boot with a Windows 7 VM running the lock screen activates (after 5 min of no activity) and when I re-activate the laptops (usually pressing the left CTRL on the keyboard) I get the login screen and the keyboard is locked and non-responsive and I can not log into my account. Variations on 2. I can not enter password but I can use CTRL-ALT-F1, etc. to switch to TTY and gain access to system. Variations on 2. I can not enter password and can not use CTRL-ALT-F1, etc. the entire keyboard appears locked out, but I can use mouse and select Switch Account to force a new login screen to appear and the keyboard now works to enter password. Variations on 2. I can not enter password and can not use CTRL-ALT-F1, etc. and I can not use the mouse, the entire input interfaces appear locked out and I have to power off the laptops to restart and be able to log in to Unity again. If I turn Lock: Off but leave Turn Screen off when inactive for 5 minutes set. If I have a VM running or no apps running, after 5 minutes the screen dims. I re-activate the system by pressing a key on the keyboard (usually the left CTRL key) and the Unity desktop re- appears. This bug only seems to occur when the Lock/Require Password when waking from suspend is active.

This seems to happen most frequently with Google Chrome and Chromium - or at least, they're two easy culprits to identify. :) Seems related to the following: https://bugs.launchpad.net/unity/+bug/1305586 I'm not sure if the fix in that bug is what caused this or if another issue arose elsewhere. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

However, occasionally I am unable to enter my password since the password box is not given focus. Clicking with the mouse in the password box also doesn't help. I've found that clicking the settings cog (top right) twice allows me to regain control of the focus and enter my password. Aside from the inability to enter my password in the password box, it seems that simply typing my password (or in fact any text) results in those keystrokes being passed to the full-screen window *behind* the greeter.

[Dx-packages] [Bug 1305586] Re: Lock screen is unusable when some windows have a keyboard/mouse grab
I'm still seeing this issue when Google Chrome is the last open ( and focused ) application upon suspend. When I typed my password in it didn't work - so I did the switch account hack and logged in - and found my password sitting in the Chrome address bar.
