Re: [SOLVED] X and video card output signal hangs with radeon...

Adding config file with:

Option "AccelMethod" "EXA"

Seems to help! Could it be glamor issue then?

Re: [SOLVED] X and video card output signal hangs with radeon...

The problem seems to be solved in current versions!

Here is my configs:

$ cat 05-glamor.conf 
Section "Module"
        Load  "dri2"
        Load  "glamoregl"
EndSection

$ cat 50-device.conf 
Section "Device"
  Identifier "Default Device"
Driver "radeon"
Option "SwapbuffersWait" "off"
Option "ColorTiling" "on"
Option "ColorTiling2D" "on"
Option "EnablePageFlip" "on"
Option "AccelDFS" "on"
Option "XV_VSYNC" "on"
Option "AccelMethod" "glamor"
#Option "AccelMethod" "EXA"

EndSection

By the way, hardware acceleration seems to work:
