I have just run apt-get upgrade and now X will not start.
After I type startx the screen blanks then everything seems to just stop. The monitor signals that it is not receiving a signal. There are no error messages.
I can only guess that there is a dependency problem that has messed up my X.
I am thinking the most expedient way to fix my problem would be to re-install phoebe-3. Is there a command line option I can enter to force install to do an upgrade and replace files even if they are newer? I did try a normal upgrade and predictably nothing was installed.
