I tried to upgrade by copying all my personal files offline, as well as
the important changes in /etc (mainly fstab for mounting my FreeBSD NFS
server directories).
The upgrade failed. The installation was made by replacing 18.04
completely, and seemed to succeed, but after rebooting both screens were
blank (have two HP 2511x flat panels, one connected via DVI and the
other via VGA from outputs on my old AMD/ATI Radeon 800XL All-in-Wonder
(R430 chipset).
I've seen this before when the system fails to correctly identify the
monitors (worked fine during installation, these have warning screens
that appear if the values used by the video card are out of range) or
when for some reason the video card is incorrectly identified or just
not supported.
Hardware is a Supermicro X7DAE (no SCSI) with currently 4GB RAM, 2 quad
core Xeon 5300 CPUs, boot disk is a RAID1 array using two 2TB Seagate
Constellation drives on a LSI 9750 (4 channel) and a 3ware 9550SX PCI-X
card used previously but not with any drives installed at this point.
There is an M-Audio sound card installed but I've not loaded the drivers
for it, yet.
I had to blow away the previous logs by reinstalling 18.04, which is
working as usual. Nothing remarkable in ".xsession-errors" or Xorg.0.log.
I'm going to replace the old Radeon card with something newer, and try
again. I have a fondness for the fonts as they appear with a Radeon card.
I'll be modifying the system so I can boot off a removable drive, so
some debugging is certainly possible.
(I'm retired, first UN*X system was a Radio Shack 16 ca 1985; have run
FreeBSD since the 386BSD days. In past years I've done UN*X mostly as a
hobby while working as a MS Windows Server system admin; retired in
2014. Running Ubuntu Studio on my main desktop (this one) and on an HP
Envy 17T laptop and Dell 6230 laptop. Only apps that I use that require
Windows at this point are Sibelius and Quicken; will try to migrate them
to a MS Windows 7 VM soon. Back end at the house consists of a 1U
FreeBSD firewall, 4U FreeBSD quad Opteron NFS/Samba server, 4U FreeBSD
quad dual core Opteron backup server, 2U FreeBSD music backup server and
tape controller (amanda), and an HP 24 slot tape library. These are all
old and will be retired Real Soon Now. I got my most recent job when the
employers realized my home system had a more sophisticated backup design
than theirs, and they served thousands.)
Thank you.
