 +Then, test VM upgrade from CentOS 7.6 to 7.7 worked OK and got full-screen graphics with Guest Additions v 6.0.10. 2 other VMs upgraded OK, but Guest Additions v6.0.12 will not install properly.  Newest kernel is kernel-3.10.0-1062.1.1.el7.x86_64 but had to boot into 3.10.0-957.27.2.el7.x86_64 to get full screen display to work.  
 + 
 +Problems:  
 +  * Windows TAT is not accessible graphically - even booting into old kernel gives non-usable graphical screen 
 +  * Work VM needs to boot into older kernel to get graphics to display 
 +  * python3 will not upgrade with the IUS repository enabled 
 +  * MATE desktop environment has double launchers 
 +    * Run: mate-panel --reset 
 +    * Then manually customize panel with launchers 
 +  * Bug with xfreerdp where CTRL-ALT-ENTER will reset X after it becomes full screen (can't toggle back and forth) 
 +    * Workaround is to use 'rdesktop' instead 
 + 
 +Guest Additions troubleshooting: 
 +  * Open ticket with VirtualBox forums 
 +  * Downgrade Virtual Box from 6.0.12 to 6.0.10 
 +  * On test VM with GA 6.0.12, see if the hardware acceleration settings need to be changed per error message that pops up (should not need changing as it will affect VirtualBox 6.1 branch) 
 +  * Search forums for error "Building the main Guest Additions 6.0.12 module for kernel 3.10.0-1062.1.1.el7.x86_64." 
 +    * Looks like 6.0.13 is a test build and 6.0.14 will have permanent fix 
 +    * Could try installing from [[https://www.virtualbox.org/wiki/Testbuilds|VirtualBox test builds]] 
 +      * This test build does work 
 + 
 +Python3 fix to use EPEL instead of IUS repo: 
 + 
 +<code> 
 +# yum remove python36u 
 +# yum remove ius-release 
 +# yum install python3 
 +# yum install python3-devel 
 +</code>
