Comment 28 for bug 988290

I don't wish to sound like a 'me too' but here I am on this latest (at time of writing) 13.04 of Ubuntu and it still occurs.

I have a VGA and PS2 KVM, 4x port by StarTech. Switching back from my work Windows desktop to Ubuntu after the screen blanker / password lock has kicked in produces a lower resolution; even if I switch the KVM wait for the monitor to state 'no signal' to possibly allow DDC to invoke prior to moving the mouse and waking the system.

The monitor is detected as Hewlett Packard 19" (HP Compaq LA1951g) and the graphics chip detected as Intel Ivybridge.

Opening up System Settings, clicking on DIsplays automatically adjusts the screen. No need to Apply, just closing retains the right resolution.
