When you write that you have "lost direct rendering", what exactly do you mean? What are the symptoms? What is different from what you were seeing before?

Which DE are you using? Is compositing disabled in the desktop environment? Have you tried re-enabling it via the DE system settings? Do you have any *.conf files in the /etc/X11/xorg.conf.d/ directory that are disabling it? Funnily enough, I have to comment out composting in xorg.conf for it to work:

Code: Select all

Section "Extensions"
   #Option "Composite" "Enable"
EndSection

I am using Kate for editing my scripts. When I wanted to switch session it took plenty of time and moving the windows on the screen was not continual as well after upgrade. Now I enabled composite and it works as before. It was good hint from you. Thanks.
I thought that it is problem of direct rendering beacause

Code: Select all

sabayon / # glxinfo
bash: glxinfo: command not found


Do you have any *.conf files in the /etc/X11/xorg.conf.d/

I followed Gentoo's Hardware 3D acceleration guide and created

Code: Select all

sabayon xorg.conf.d # cat 10-dri.conf
Section "Device"
  Driver "fglrx"
EndSection
Section "dri"
  Mode 0666
EndSection


but I hat to remove it because x-server did not start after reboot. I was trying to change driver but no success.

It helps if you install x11-apps/mesa-progs.
