Hmm, the string "EGL search path is" and the corresponding code was
removed upstream for Mesa 10.6. Look for instances of libEGL.so.1* other

removing those helps.
I'm not sure about what you're asking.
On the problematic system apparently there are no packages installed
containing libEGL*.*
apt-file search libEGL.so
libegl1-glvnd-nvidia: /usr/lib/x86_64-linux-gnu/nvidia/current/libEGL.so.1
libegl1-mesa: /usr/lib/x86_64-linux-gnu/libEGL.so.1
libegl1-mesa: /usr/lib/x86_64-linux-gnu/libEGL.so.1.0.0
libegl1-mesa-dev: /usr/lib/x86_64-linux-gnu/libEGL.so
libegl1-nvidia: /usr/lib/x86_64-linux-gnu/nvidia/current/libEGL.so.1
libegl1-nvidia: /usr/lib/x86_64-linux-gnu/nvidia/current/libEGL.so.375.66
libegl1-nvidia-legacy-340xx:
/usr/lib/x86_64-linux-gnu/nvidia/legacy-340xx/libEGL.so.1
libegl1-nvidia-legacy-340xx:
/usr/lib/x86_64-linux-gnu/nvidia/legacy-340xx/libEGL.so.340.102
virtualbox-guest-x11: /usr/lib/virtualbox/additions/libEGL.so
virtualbox-guest-x11: /usr/lib/virtualbox/additions/libEGL.so.1
but none of these packages are installed.
But
find /usr/lib/x86_64-linux-gnu/ -name libEGL*.*
/usr/lib/x86_64-linux-gnu/libEGL.so.1
/usr/lib/x86_64-linux-gnu/libEGL.so.1.0.0
ls -l /usr/lib/x86_64-linux-gnu/libEGL.so.1
lrwxrwxrwx 1 root root 15 Jul 17 00:57
/usr/lib/x86_64-linux-gnu/libEGL.so.1 -> libEGL.so.1.0.0
aptitude reinstall glx-alternative-mesa
update-alternatives: warning: forcing reinstallation of alternative
/usr/lib/mesa-diverted because link group glx is broken
On the working box I get:
find /usr/lib/x86_64-linux-gnu/ -name libEGL*.*
/usr/lib/x86_64-linux-gnu/libEGL.so.1
ls -l /usr/lib/x86_64-linux-gnu/libEGL.so.1
lrwxrwxrwx 1 root root 51 Jun 10 2016
/usr/lib/x86_64-linux-gnu/libEGL.so.1 ->
/etc/alternatives/glx--libEGL.so.1-x86_64-linux-gnu
Does the same problem happen with 1:7.8.0-1+b1 with
Option "AccelMethod" "glamor"
in /etc/X11/xorg.conf ?
Older xserver-xorg-video-radeon with that option DOESN'T WORK.
Black screen, text cursor at the top right corner ( _ ).
Right, as expected the problem is specific to glamor, which is the
default for your GPU in 7.9.0 but wasn't yet in 7.8.0. This means in the
worst case you can work around the problem with
Option "AccelMethod" "EXA"
in /etc/X11/xorg.conf.
Thanks, this solved the problem.
Could I suggest to add some notes in the changelog before closing the
bug?
It's just a workaround. We don't know yet what the problem is, though
it's likely specific to your system.
Are you saying it is something more related to the installation history
of that box rather then to the specific hardware?
Or it cold be a mix of the two?
Could I exploit the fact that I've 2 nearly identical boxes to track
down the problem?
thanks
