Public bug reported:
1024x768 resolution is not available by default in Ubuntu Trusty when
connecting to Cisco KVM. It works fine with RHEL 6.5 (xorg-xserver
x1.13.0) and SLES 11.4 (xorg-xserver v1.6.5).
The workaround to enable display in Ubuntu Trusty is:
1. Stop lightdm (service lightdm stop)
2. Generate an xorg.conf file. Item #54 you need to add -> Modes "1024x768"
(will attach screenshot in comments)
3. Copy the file to /etc
4. Start lightdm again (service lightdm start)
