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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/988290 Title: Resolution change with KVM switch on Precise Status in “xserver-xorg-video-intel” package in Ubuntu: Invalid Bug description: I have a machine that shares monitor, keyboard and mouse with a second machine via a standard KVM-Switch (USB/VGA). After updating to precise beta yesterday, I noticed that, after having worked with the other machine for a while and switching back to the precise machine, screen resolution has changed to 800x600. Just opening "Monitors" from gnome- system-settings restores the original resolution of 1280x1024, you don't need to change anything. This is reproducible, if you switch away from the machine long enough (I guess until the screensaver gets invoked) resolution will be changed when you come back. This was not the case with oneiric. Is there some way to disable this behaviour?
