H'lo Alan, Here's what genlop found for "x11.*" since June 1: Mon Jun 15 00:20:36 2009 >>> x11-libs/openmotif-2.3.2 Sun Jun 21 11:58:51 2009 >>> x11-drivers/ati-drivers-8.552-r2 Sun Jun 21 17:59:39 2009 >>> x11-drivers/ati-drivers-8.552-r2 Sun Jun 21 19:48:37 2009 >>> x11-drivers/ati-drivers-8.552-r2 *** GOOD REBOOT Fri Jul 10 23:28:06 2009 >>> x11-libs/qt-test-4.5.1 Sat Jul 11 07:12:12 2009 >>> x11-themes/gtk-engines-ubuntulooks-0.9.12-r3 Sat Jul 25 13:02:56 2009 >>> x11-drivers/ati-drivers-8.552-r2 Sun Jul 26 08:24:12 2009 >>> >>> x11-libs/libgksu-2.0.9 Sun Jul 26 08:30:31 2009 >>> x11-libs/gksu-2.0.2 Tue Jul 28 07:24:07 2009 >>> x11-drivers/ati-drivers-8.552-r2 Fri Aug 7 18:25:05 2009 >>> x11-libs/fltk-2.0_pre6786-r1 ati-drivers-8.552-r2 package was present at the reboot and has been reinstalled since. None of these x11 packages seem relevant. Grepping for EDID finds no hits in the old log and multiple occurrences of RADEON in the new log. Comparing the logs shows VESA in old, but not new. Here are grep counts: r...@osage log # grep -c VESA Xorg.0.old.log Xorg.0.new.log Xorg.0.old.log:79 Xorg.0.new.log:4 r...@osage log # grep -c RADEON Xorg.0.old.log Xorg.0.new.log Xorg.0.old.log:0 Xorg.0.new.log:385 Perhaps I need to specify VESA in xorg.conf somehow ???
