output of dmesg

I have a problem with network and desktop environment after resume from suspend/hibernate.

1) The case of the GNOME desktop. After resume the screen is blinking (showing my wallpaper).
2) The Kde, resume is ok, however no network. The wireless device is swithched off and it is not possible to activate it from the keyboard. In my home I use pppoe over eth0. Similarly, I'm not able activate pppoe nerther from networkmanager nor from network center.

In both cases 1 and 2, everything return after restart of X with alt-ctl-del.

The hardware HP ENVY 1210nr, two video cards, intel(integrated) and radeon(redwood) - discrete. I use vga-swithcheroo to switch off the radeon. This is done by rc.local that is used by systemd (I found info in the web).
Before suspend I switch on the radeon card with  

echo ON > /sys/kernel/debug/vgaswitcheroo/switch
