Unsubscribing sponsors as per Martin Pitt's comment #21, as the patch is not suitable for SRU.
However, I've gone ahead and fleshed out the SRU request in the description. Hopefully that'll save a bit of work if/when a valid fix does become available. Shih-Yuan, thank you for your attention to this problem and for proposing the patch. ** Description changed: + [Problem] + Logging out of a second user session results in a black screen with blinking cursor, until you manually switch to vt7. Might also be caused when screen is locked because of inactivity. + [Impact] - <fill me in with explanation of severity and frequency of bug on users and justification for backporting the fix to the stable release> + Frequency of occurrence may be about 1 in 4. Not a hardware-specific problem, so can be encountered by most users. [Development Fix] - <fill me in with an explanation of how the bug has been addressed in the development branch, including the relevant version numbers of packages modified in order to implement the fix. > + Adding a VT_WAITACTIVE after the VT_ACTIVATE ioctl helps reduce the chance of a race condition between LightDM, the kernel, ConsoleKit, and X, but is not a complete solution. This change was introduced to Precise as of version 1.1.2-0ubuntu1 on Feb 10th. [Stable Fix] - <fill me in by pointing out a minimal patch applicable to the stable version of the package.> + The development change was not a complete fix. Thus the change is not valid for SRUing. [Text Case] - <fill me in with detailed *instructions* on how to reproduce the bug. This will be used by people later on to verify the updated package fixes the problem.> - 1. - 2. - 3. - Broken Behavior: - Fixed Behavior: + 1. Have a multi-user system + 2. Start up and log in as a user + 3. Use the User Menu to switch to another user + 4. You will be at the Unity Greeter, log in as the second user + 5. The second user session will load + 6. Choose Log Out from the power/setting menu + 7. You will be at the Unity Greeter + 8. select and enter the password for the logged in user + Broken Behavior: + The screen turns black and shows a blinking cursor + Manually switching to VT7 shows the first user session, and works fine + + Fixed Behavior: + Automatically returned to VT7 after entering the password for the first user [Regression Potential] - <fill me in with a discussion of likelihood and potential severity of regressions and how users could get inadvertently affected. + <fill me in with a discussion of likelihood and potential severity of regressions and how users could get inadvertently affected.
