[ubuntu-studio-users] Dual display problem solved.

[Mike Squires]

I have two HP 2511x HD displays connected to my Ubuntu Studio 
workstation, currently running 18.04.

With the previous ATI Radeon All-in-Wonder card some applications were 
able to display over all parts of the two displays, some were not.  
Windows would vanish about 1/3 of the way to the right on the secondary 
display.  For example, "xterm" had no problems but "Terminal Emulator" 
did.  I replaced the All-in-Wonder, with its 256Mb of memory, with an 
AMD Radeon 5550 card with 1GB of RAM. (Probably needed anyway, the 
All-in-Wonder fell apart, as others have, when removed as bad solder 
joints failed).

This solved the problem.

I am hoping that this change also solves my problems with upgrading to 
18.10 which failed with the previous card (blank display at first login 
screen, no display problems before).
