After performing a suspend/resume cycle, the screen displays only the Fedora logo (as in during the boot process). I see the mouse pointer and can move it, but I cannot interact with any other process in my X session.

The machine seems to be running normally, I can Ctrl+Alt+F2 to login into a terminal and use it normally: ps indicates processes are still running, including X, etc., but when trying to launch any graphical application, the process just hangs as if waiting for the screen, and nothing else happens until I kill it via Ctrl+C. Doing Ctrl+Alt+F1 returns to the screen with the Fedora logo and nothing more.

If I kill the X process, then the login screen is displayed again and I can use my computer normally. Is there a way to restore my graphical session without killing X?

Or, more precisely: which application is responsible for displaying the Fedora logo? Is it the X process itself? It seems as if I could "kill" it, the other processes might be "visible" again, but I find no information about what is drawing this logo on my screen.

Notes: I upgraded from Fedora 18 to 20, formatting the root partition but not the home partition. I had some issues with the DISPLAY variable but couldn't find anything specific about them. I had never had an issue with Fedora 18.

Edit: After some tests, I do not know the exact cause of the error. If I suspend my machine, wait a few seconds and resume it, the error does not happen. On the other hand, it happened once without suspend/resume, after doing a Ctrl+Alt+F2 to another terminal and returning to the first one. A weird thing is that, even when I cannot see the screen (only the Fedora logo), the mouse pointer turns into a "text cursor" in some parts of the screen, as if the underlying application were still there.

I see this issue too. I've brought it up on the Fedora testing list but we haven't been able to isolate the cause of this behaviour yet. The worst part is that it doesn't happen each time and therefore it's more difficult to debug. :(

That's plymouth, you can tell it to stop with 'plymouth --quit', I am not sure this would let the graphical desktop show up though, you can try it.

If you don't care much about boot splash/screens, you can disable plymouth altogether by adding 'plymouth.enable=0' to the kernel command line (and remove 'rhgb quiet' if you want to see the boot messages).

Naw. It's more an X/nouveau/kernel issue I think. but yeah, not enough info to decide yet.

I have this issue with ThinkPad t430 with Nvidia NVS 5400M 2GB graphic card, with Fedora 20. Is there any solution?!!!

I'm experiencing the same symptoms here. I tried debugging the problem using these instructions: fedoraproject.org/wiki/Common_kernel_problems?rd=KernelCommonProblems#Suspend.2FResume_failure

All I get after seeing the Fedora logo again is this:

[    1.236514]   hash matches drivers/base/power/main.c:647
[    1.236517]  ep_81: hash matches
[    1.236520]  ep_81: hash matches
[    1.236522]  ep_81: hash matches
[    1.236523]  ep_81: hash matches

ep_81 seems to have to do something with USB - maybe a problem with the USB kernel module?

[root@daedalus ~]# find / -name ep_81

I too was curious what program was presenting this "Fedora logo" screen and maybe @AhmadS is on to something, plymouth did run when this logo screen was on and it's not running usually. While the logo screen was on, I switched to the textconsole and saved an output of "ps auxww", then I did "init 3 && init 5" and saved another output. After omitting the unintersting stuff, the following programs were not running any more:

$ diff ps.before ps.after
<  /bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3
>  /usr/lib64/tumbler-1/tumblerd
<  /usr/libexec/at-spi2-registryd --use-gnome-session
<  /usr/libexec/bluetooth/bluetoothd
<  /usr/libexec/dconf-service
<  /usr/libexec/gconfd-2
<  /usr/libexec/gvfsd-http --spawner :1.3 /org/gtk/gvfs/exec_spaw/1
<  /usr/libexec/gvfsd-metadata
<  @usr/sbin/plymouthd --mode=boot --pid-file=/var/run/plymouth/pid --attach-to-session
>  xscreensaver -no-splash

I was impressed to see that it is possible in Fedora 20 to "yum remove plymouth" I did just that, maybe it helps something.

plymouth is added to the kernel initramfs, so after uninstalling plymouth I think you need to regenerate the initramfs with 'dracut -f'.

Here it seems as if removing plymouth helped. For three days I haven't seen the logo after suspend yet!
