From the terminal: $ tail /var/log/dpkg.log should show the last package that you installed. The whole log can be rather long so open it in nano: nano /var/log/dpkg.log if you need to see other than the last installed package. For instance, yesterday I installed quite a few packages, the last one I installed was xvidcap: $ tail /var/log/dpkg.log 2009-06-27 14:45:54 status unpacked xvidcap 1.1.7-0.2ubuntu1 2009-06-27 14:45:54 status unpacked xvidcap 1.1.7-0.2ubuntu1 2009-06-27 14:45:54 trigproc man-db 2.5.5-1build1 2.5.5-1build1 2009-06-27 14:45:54 status half-configured man-db 2.5.5-1build1 2009-06-27 14:46:17 status installed man-db 2.5.5-1build1 2009-06-27 14:46:26 startup packages configure 2009-06-27 14:46:26 configure xvidcap 1.1.7-0.2ubuntu1 1.1.7-0.2ubuntu1 2009-06-27 14:46:26 status unpacked xvidcap 1.1.7-0.2ubuntu1 2009-06-27 14:46:29 status half-configured xvidcap 1.1.7-0.2ubuntu1 2009-06-27 14:46:29 status installed xvidcap 1.1.7-0.2ubuntu1 Alternately; boot into recovery mode, run the xfix util & see if that fixes the issue - or from the terminal: $ /usr/share/recovery-mode/options/xfix </pre> </blockquote> I tried the xfix option and it didn't work, and you were right about it being a long list. I installed lots of things before I rebooted, and upgraded the kernal to the -13-generic from -11-generic. The driver was "xorg-driver-fglrx" I did an "apt-get remove xorg-driver-fglrx" after that my system booted without any problems. Thanks again; Stephen Oulton </body> </html>
