Comment 60 for bug 57153

Hi,

I am an experienced computer user / developer but never used atp-get,
dpkp or whatever before. Only update-manager and Synaptic. When I got
that problem (Dell Inspiron 8600 with ATI Mobility 9600 M10) I
downgraded X server manually using the console program "adaptive". It is
not as simple as Synaptic but at least it is menu driven and has online
help. That made things easier. The most serious problem was to find out
which package was "the bad one". I remembered it by heart because it was
the only package that was updated that day. Things might be much more
difficult if you can't remember updated packages.

Why not writing a program that "undo"s all package updates from a
history? That should be easily runnable (in worst case from an extra
entry in grub that boots into an minimal Ubuntu that just undo the
latest package update and reboots).

Regards, Jochen
