Bug Description

In Karmic (and earlier) the following binaries are compiled with an executable stack on i386, which should be fixed[1]:
  fglrx-amdcccle:
    /usr/bin/amdcccle
  xorg-driver-fglrx:
    /usr/bin/atiode
    /usr/sbin/amdnotifyui
    /usr/lib/dri/fglrx_dri.so
    /usr/lib/libGL.so.1.2

Thanks!

AMD64, ATI x1250. Blank screen on restart, no response on Ctrl/Alt/F[0-9], no response to Ctrl/Alt/Del. Did respond to pressing the Power button, and powered off.

Although sounds bad, this is actually an improvement over the previous versions -- machine would not respond at all.

You can't have accurate data for this until AMD releases a driver that
is compatible with karmic (currently none such exists).

With version 2:8.660-0ubuntu1 on amd64, the list of files with an
executable stack is shorter:

xorg-driver-fglrx:
 /usr/lib/libGL.so.1.2
 /usr/lib/dri/fglrx_dri.so
 /usr/lib32/libGL.so.1.2
 /usr/lib32/dri/fglrx_dri.so

I used "execstack -c" to remove the executable stack from those and
rebooted. I have only tested a few minutes, but so far everything
seems OK.

Tested:
 xv - mplayer -vo xv
 OpenGL - glxgears, fgl_glxgears, ppracer, mplayer -vo gl2

This is using an integrated HD3200 card:

01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3200 Graphics

This bug was fixed in the package fglrx-installer - 2:8.660-0ubuntu3

---------------
fglrx-installer (2:8.660-0ubuntu3) karmic; urgency=low

  [ Alberto Milone]
  * debian/control:
    - Change the section of the -modaliases package to "admin" as
      the package is not "restricted" (LP: #429153).

  [ Kees Cook ]
  * debian/control:
    - Add build dependency on execstack.
  * debian/rules:
    - Drop executable stack markings from precompiled
      binaries (LP: #409440).
