Public bug reported:
Depending on how you look at it, this may or may not be considered a
bug. The problem developed immediately after replacing my graphics
adaptor because upgrading to Ubuntu 13.04 failed stating there was a
problem with my video.
What happens is a bit strange because the problem is self correcting but
fails after restarting for reasons that are unclear - to me at least. I
think perhaps the system recognizes that it is having problems when it
first comes up and then cycles through alternative configurations until
it finds one that works; and when I say works, it works perfectly. The
scenario is as follows:
1. I start the day by booting up the cold system. It comes up with a
screen that though largely correct, is rapidly fluttering back and
forth, but no so badly that I can't log in. However logging in then
brings up a blank gray screen that is also rapidly fluttering.
2. I then toggle my monitor, keyboard and mouse to my MS Windows 8 box
and check email, the news, etc., and after awhile switch back to my
fluttering Ubuntu box, still with a fluttering blank gray screen. I
then do a hardware reset and switch back to my MS Windows Box and browse
the news more in depth this time. Finally after awhile, I switch back
to my Ubuntu box and find the screen now is no longer fluttering with my
login screen. I login and everything continues to work perfectly.
3. The next day, I start at step 1 again because try as I might, I
can't find out how to save the working configuration.
There is no Xorg.conf file other than older ones with various suffixes:

The default-display-manager contains:
/usr/sbin/lightdm
and /usr/bin/Xorg is some sort of ELF file.
Most of the "fixes" I've found are ones that update xorg.conf but since
a system wide search has not located a xorg.conf file, presumably
something else is being used.
My hardware according to the Asus box is:
HD 6450 SILENT/DI/1GD3(LP)
the Part No.:
90-C1CQ0F-L0AANAYZ
and the serial number:
D4C0YZ239187
The lspci command nets out to:
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Caicos [Radeon HD 6450/7450/8450]
Presumably this will net out to some sort of reconfiguration, or more
likely a means to save the currently working configuration (I am, by the
way, reporting this "bug" on the failing box after a number of reboots
and hardware resets before finally arriving at the now perfectly
operational screen).
Any thoughts would be greatly appreciated.
If any additional information is needed, let me know and I'll provide it
as needed. I've tried to pare down much of the data I've gathered to
provide that which I thought to be most meaningful.
Thanks....
Phil
