Red Hat Bugzilla – Bug 1007221
kernel-3.11.0-x.fc20.x86_64 doesnt flush memory as part of rebooting so leaves leftovers if dont power off?
Last modified: 2014-05-24 20:10:19 EDT
Description of problem:
stale video from previous session appears after reboot (not after power off)
bios boot graphic,
fedora scroller at bottom of screen,
open some user application
starting with machine off
power up and log in
open some window or run some program so that there will be something visible other than the desktop.
now reboot (not power off) and login again (enter username/password).
during the login process the prior task that you had running before the restart is briefly visible in full resolution on the screen until the login process completes.
this stale video (depending on how fast complete login steps?):
sometimes happens before grub menu comes up (?)
( if stale video is displayed before the login screen
it doesnt show your task from before reboot this time
but shows lower resolution shot of bios boot graphic
[an interlace frame of the bios boot graphic?]
after the full resolution bios boot graphic
had been cleared from screen )
sometimes happens before login screen
( usually stale video of pre-reboot task
but possibly bios boot graphic interlace frame )
sometimes happens after login screen but before the desktop is fully up
( stale video of pre-reboot task )
this stale video doesnt happen when power on into kernel-3.10.10-200.fc19.x86_64 and then rebooting back into kernel-3.10.10-200.fc19.x86_64
this stale video DOES happen when (on otherwise fully updated fc19 system):
rebooted from 3.10.10-200.fc19.x86_64 to 3.11.0-300.fc20.x86_64
rebooted from 3.11.0-300.fc20.x86_64 to 3.11.0-300.fc20.x86_64
rebooted from 3.11.0-300.fc20.x86_64 to 3.10.10-200.fc19.x86_64 (?)
( redisplays an interlace frame of boot bios graphic before login screen
[but NOT stale video of your task from before the reboot]
after login before login process completes only clean desktop )
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. system powered off
2. boot, log in, launch a program so something is on screen
3. reboot (not poweroff-delay-poweron), login
4. see stale video briefly as desktop is being set up
see video snapshot from previous boot after reboot
see default clear video not stale user desktop image from previous logon
aditional system information:
not getting stale images.
leaving open for now and will close if continues to work.
Still OK ?
ja, still good including upto
thanks again :')
