Description of problem: When the machine wakes from sleep, the last visible screen flashes for a moment (1/4 second) before the user is locked out and prompted for a password. For security reasons this should be suppressed - a user approaching a sleeping machine should not be able to get a glimpse of what was on the screen - even for a moment. Version-Release number of selected component (if applicable): How reproducible: intermittent but at least daily Steps to Reproduce: 1. let the machine go to sleep (typically by closing the laptop lid) 2. wake it 3. Actual results: Expected results: Additional info:
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Jeffrey, Do you still see this issue? Now that g-ss has changed quite a bit since Comment #0 it may have been fixed. Now it worked fine on my several F12 (no glimpse of last visible screen).
I still see this with gnome-screensaver-2.28.3-1.fc12.x86_64.
James, Thanks for confirming the issue is still present. I tried the procedure in Comment #0 1. let the machine go to sleep, by closing the laptop lid 2. wake it and I saw a blank screen for a moment, then the lock screen; no glimpse of screen prior to sleep. I am also using gss-2.28.3-1.fc12.x86_64, on Sony VAIO VGN-FE890, Intel 945GM graphic chip. Do you see this issue consistently? Is the system under high CPU load? Does the power source (AC/battery) make any difference? Do the different themes (Blank screen, Cosmos, etc) make any difference? Any idea how I may be able to reproduce this issue? Thanks.
Tim, One way I know of getting a *brief* gimpse of the underlying desktop is to switch VT to a text console, wait enough time for the screensaver, then switch back to X. It is at that point that the display locks, as if I had immediately pressed Ctrl+Alt+L --- so although the timeout's been registered, the screensaver hasn't started. However, this might be a red-herring and a different problem. I'm not sure yet what circumstances lead to the worse one, where the underlying desktop persists (but its image is largely frozen). I'll try doing more sleep-testing...
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
