[SOLVED] Fuzzy screen after resume

Hello,

since I upgraded from XFCE 4.10 to 4.12, I noticed that my machine doesn't resume properly from suspend anymore.

See here : http://i.imgur.com/gnJRTGK.jpg

I can still push the power button to logout blindly (and screen is restored after logout, because X seems to restart) or send "halt -p" (or pkill X) through SSH.

What did I tried to resolve this ?

disabled xfce's compositor
rebuilt : kernel+modules, emerge -v1 $(qlist -IC x11-drivers), emerge -v1 $(qlist -IC xfce-base)
added this to my /etc/X11/xorg.conf : Option "ModeValidation" "NoTotalSizeCheck"

Some informations about my setup :

I have a 8600M GT with x11-drivers/nvidia-drivers (340.76, because up to date drivers dropped support of my card) and kernel 4.0.5
my /etc/X11/xorg.conf : http://pastebin.com/raw.php?i=cFWmgB9k
my /usr/src/linux/.config : http://pastebin.com/raw.php?i=WMzzdA3K
my dmesg : http://pastebin.com/raw.php?i=bBDtXwMt
my Xorg.0.log : http://pastebin.com/raw.php?i=BAP5Hm1R

Just out of curiousity.

Does this resume issue also happens in lets say another desctop environment without such bloat, like i3wm?
Can you test this on a plain x-session please?

This looks like more like artefacts and I think its the nvidia-drivers fault, so I want to verify if its the desctop environment or the x-server + kernel + nivida-drivers.

Could be mesa too ...

I have a 9800m gts and I was not aware that the binary drivers works with 4.x.x kernel too.

I am also curious if you get this behaviour when you resume only from command line interface without x-server running ...

Hello and thank you for your reply

!

I've just emerged i3 and i3 status for testing purposes.. It's kind of new for me, but it feels nice.

Okay, so far, I tested :

without X ? Do you mean "on TTY1" ? I ran a "echo 'mem' > /sys/power/state" on TTY1 : no fuzzy screen (even xfce on tty7, no issues)
i3wm : ran two "echo 'mem' > /sys/power/state" and I have not had any screen corruptions after resume
plain x-session ? I don't know how to do this (sorry!)

So : I have to assume that it is XFCE related because I have no problems on i3wm ?

Also, I have to admit that nvidia-drivers doesn't compile well on 4.x.x : I used a small patch which can be found on the second post of this topic.

I think i start the plain x session with startx only in cli, or xdm in cli. one of these ...

seems so an xfce4 issue ...

Indeed, it was a XFCE issue : the culprit seems to be xfce-extra/xfce4-power-manager.

So, "/usr/sbin/xfce4-pm-helper" was launched when I closed my laptop : I disabled it with :
- running xfce4-settings-manager
- xfce power manager
- on general, "when laptop lid is closed", it was on "suspend" : I changed-it to "shutdown screen"

And to keep suspend when I close the laptop, I've changed my ACPI configuration to this :
