[NBLUG/talk] Ubuntu 12.04 dual monitor problems [not solved but working...]

[s smith]

Hi Chris.

Thanks for the reply.  I got it working and the results are below.  
Thanks for mentioning xorg.conf.  I copied the working 11.04 conf file 
into the 12.04 directory and after doing the suitable goats entrails on 
the keyboard at midnight etc... rebooted and it worked.  Miracles still 
happen I guess :)  See below for other things I did first.

In the system tools settings menu there is an 'unsupported drivers' item 
that has (in my case) an ATI driver's section that has proprietary 
drivers 'tested but not supported by Ubuntu.'  My computer is a little 
HP they probably didn't hit this configuration in their testing.  I 
already know it's power-supply limited and won't support another display 
but don't care.  It's quad-core 64-bit 12Gb 1Tb system for $300.  I 
bought it for compute power not display.

yes.

I have the log file and saw lots of debug warnings but no errors -- 
unless the last debug statement is the error.  The log file is 
/var/log/jockey.log.  I attached the last few lines but will be more 
than happy to send you the whole thing.

Out of curiosity I rebooted the live CD to do some testing.  I am able 
to select the right configuration.  The live CD identifies the new 
monitor correctly as an "AOC 23" where the install finds a "laptop."  
Interestingly there is no /etc/X11/xorg.conf on the live boot so they 
are doing something entirely different for graphics on the live-CD.  
This also means that just because you can configure your displays on the 
live CD -- you can't assume things  will work when the system is 
installed.  Also, the mouse on the live-cd didn't work correctly in 
dual-monitor mode.

After copying the 11.04 conf file into the 12.04 /etc/X11 directory the 
system still identified my new monitor as a laptop and I still had to go 
through the configuration process -- but everything worked including my 
wacom.  I still can't install the proprietary drivers though...

I have the working and non-working files and will be posting to the guys 
with a problem.  If you want my files, please let me know.  I'll be more 
than happy to send 'em.
