Public bug reported:
This was a question but no answer or comments so I converted it to a bug
report - jankom
This is a "mature" 32 bit machine. Had 12.04, then distro upgraded to
14.04, and recently distro upgraded to 16.04. After that it did not
boot, so I decided to rebuild the machine with a virgin installation
(reformat, etc.) Installation completed successfully, but after that the
machine would not boot into the new installation. Grub is there, boot
process starts, even gets to the stage when the x-server starts, but
then it falls back to VGA mode (screen shows fsck result being OK) and
continues to start x-server, and so on and on, repeating this loop.
Note (1): I can start 16.04 from the CD tray Ubuntu mode. If I look at
syslog and xserver.0.log from the mounted 16.04 root filesystem (the one
that would not boot) I can see no obvious reason for this behavior of
getting stuck in a loop at boot process, although I have limited
expertise in Ubuntu architecture.
Note (2): Rescue mode does not help either
Note (3): again, this is a 32 bit desktop machine with Athlon Duron CPU
and nvidia chipsets. The machine has been running well with 12.04 or
14.04 (except for a still outstanding scanner bug on 14.04, but I don't
think it has anything to do with this failure to boot on a shiny new
16.04 installation.
Note (4): I checked, I have plenty of free disk-space, and if I dual
boot into my old Fedora-3 installation everything is fine. Therefore I
do not think the problem would be hardware failure.
Note (5): finally (if it helps) the display is a 24" LCD. Booting from
the 16.04 CD in live session mode the resolution is 1920x1080, and
everything is fine. Just booting into the installed 16.04 on the hard
disk fails with an endless loop between text and graphics mode.
