bcstrawn; Hi !
Here is what I have done to see my boot messages.
1. Edit /etc/defaulr/grub -> remove the terms "quiet splash" and in the line
change it to:
Don't forget to update grub
2. change in /etc/init/tty1.conf. By default the virtual console logins clear the screen when they start; on tty1, this has the effect of erasing the last screen's worth of boot-time messages. To tell getty not to do this, we add --noclear to the exec line:
2a. grub kernel to boot-> "e" to edit -> kernel boot line add "text' without the quotes;
exec /sbin/getty --noclear -8 38400 tty1
ctl-x to boot to command line; log in then: -> ctl-alt-f7 to go to the GUI ; ctl-alt-f1 return to console: -> ctl-alt-f7 and on this screen is all the boot messages !
will give you a text file of the lightdm startup messages.
sudo service lightdm restart 2> ~/Desktop/errors.txt
finally if you think it is a graphics driver issue look also into the following files.
/var/log/Xorg.0.log and in your home directory, enable hidden files (ctl-h), and look at .xsession-errors.
just try'n to help <== BDQ
