screens remain black after I resume from suspend

Message

Hello, everyone,

I encounter some problems now. I install Gentoo several days ago, also have Xfce installed, everything works ok until I try to suspend (to RAM), when I try to resume from it. Two conditions may happen:

1. The screens do turn on, but it remains black;
2. The screens do not turn on, there is no reaction to keystrokes.

I don't know whether it is a problem of nvidia proprietor driver (which I install from Gentoo repository through "emerge --ask x11-drivers/nvidia-drivers").

I try kernels (from "genkernel all" and "gentoo-kernel-dist"), but the results do not change.

I don't know what to do now. Does someone know something about this? Appreciate it first.

Hi
Plz disable screen-lock and try again.
Are you trying to suspend or hibernate?
If the second you need swap.
Plz try

Code: Select all

egrep -i "suspend|resume|screen|auth" /var/log/Xorg.0.log
egrep -i "suspend|resume|screen|auth" /var/log/messages

I don't know whether it is a problem of nvidia proprietor driver (which I install from Gentoo repository through "emerge --ask x11-drivers/nvidia-drivers").

Do NOT explicitly emerge nvidia-drivers
Just in make.conf append
VIDEO_CARDS="nvidia"
and rebuild @world
Plz run

Code: Select all

emerge --deselect nvidia-drivers
emerge -uDUav @world

Thank you very much for your help, I try disabling screensaver just now, but it does not work.

I am trying to suspend (to RAM)

Code: Select all

[   399.342] (==) No Layout section.  Using the first Screen section.
[   399.342] (==) No screen section available. Using defaults.
[   399.342] (**) |-->Screen "Default Screen Section" (0)
[   399.343] (==) No device specified for screen "Default Screen Section".
[   399.343] (==) No monitor specified for screen "Default Screen Section".
[   399.346] (II) NVIDIA(0): Creating default Display subsection in Screen section
        "Default Screen Section" for depth/fbbpp 24/32
[   399.790] (II) NVIDIA(0): Virtual screen size determined to be 3840 x 1080
[   399.960] (II) Initializing extension MIT-SCREEN-SAVER
[   399.960] (II) GLX: Another vendor is already registered for screen 0

As for not emerge nvidia-driver explicitly, I have noticed this now, and now I install it as you say.

I have also try hibernate, the problem is the same, everything seems work well except that the two screens still have no content (The screens are turned on, just no content!)

Maybe you miss something like

Code: Select all

Section "Screen"
        Identifier "nvidia"
        Device "nvidia"
        Option "AllowEmptyInitialConfiguration"
EndSection

in xorg.conf
Plz run

Code: Select all

 nvidia-xconfig

to produce a xorg.conf

I add the
Option "Allow..." to Section "Screen" area. Now it looks like

Code: Select all

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 470.57.02

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Section "Files"
EndSection

Section "InputDevice"
    # generated from data in "/etc/conf.d/gpm"
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol"
    Option         "Device" "/dev/input/mice"
    Option         "Emulate3Buttons" "no"
    Option         "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Keyboard0"
    Driver         "kbd"
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    Option         "AllowEmptyInitialConfiguration"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Is this enough?

This does not work.

Will it be a problem of display manager, I do not use a DM, I use startx instead.

I forget to provide the result of

Code: Select all

There seems some prompts about what happened. But I can not understand it.

If you use
nvidia-xconfig
you should NOT append my example "screen section",just what is produced by the command.
Yes try with lightdm.
I use xfce with lightdm and just now I checked:
Suspend works just fine
Your output aslo does not look very terrible.
Maybe some alsa/pulseaudio problem.
Plz try with the nvidia-xconfig+lightdm
How do you effect the suspend?
By closing the lid?
Plz check also xfce->settings-manager->power options

It works, though I don't know what happened when use only starts, but I'm still very happy that I can suspend/hibernate.

Thank you very much, alamahant!!

I think what really matter is the lightdm, it must be some restrictions with startx, may be some authentication/priviledge problem (I guess).

And, actually, I am using a desktop computer.
