Description Ricardo Graça 2010-11-22 20:54:39 UTC
Version: unspecified (using KDE 4.5.3) OS: Linux If, in a session, I connect an external monitor to my laptop and disable the internal monitor, on the next session if I don't have the external monitor connected during the boot process, when KRandrTray starts up it blanks (disables?) the internal monitor. I don't know exactly how it does it, but not even my laptop's function key to cycle through screens works after this (I think this key invokes xrandr). The only way to get a display back is to connect an external monitor (which strangely is also blank after connecting) and then use the laptop's function key again and eventually one of the displays comes up. Reproducible: Always Steps to Reproduce: 1. Connect external monitor to the computer 2. Open KRandr to change the display settings and disable the internal monitor 3. Make sure KRandrTray is set to autostart during boot 4. Reboot 5. Disconnect the external monitor as soon as possible Actual Results: KRandrTray blanks the internal monitor when it starts Expected Results: Somehow known that the external monitor is not connected and so it shouldn't try to restore the previous session's settings (if that is indeed what is going on) I'm using the acpi-eeepc-generic scripts

This still happens in version 4.5.5.

Could you or someone else please test my patch in Bug #265955? (In reply to comment #0) > I don't know exactly how it does it, but not > even my laptop's function key to cycle through screens works after this (I > think this key invokes xrandr). kded_randrmonitor was ignoring the function key when only one monitor was connected.

@alter Your patch works and fixes this bug. This can be marked as solved as far as I'm concerned.
