Display Configuration Screenshot
This is a bug in kernel and/or graphics driver. From the kernel message and lshw output it's clear that you have dual graphics setup - AMD and Intel, both connected to the same screen which makes kernel think that you have two screens. You can try disabling one of the cards in BIOS. That might solve the problem. Unfortunately there's nothing much we can do about this in KScreen. The only slightly confusing thing is why the outputs are called "LVDS1" and "LVDS-1" in the KCM when xrandr reports "LVDS" and "LVDS2", but that might simply be a consequence of having two embedded outputs. I didn't see this behaviour before KUbuntu 13.04. There was allways only one monitor. The names have apparently changed when after I updraded the BIOS. It was the last thing I thought that could solve the problem, but it didn't. The screenshot with the names LVDS1 and LVDS-1 is from before the BIOS upgrade. It can easily be a regression in kernel or graphics drivers that was introduced in the update that's available in 13.04. I suggest taking this to Launchpad where the issue can be triaged and assigned to appropriate developers or upstreamed to respective bug tracker.

The problem appears to be fixed after this update: --------- Version: 1.0.2.1-0ubuntu0.1 2013-12-03 18:06:51 UTC kscreen (1.0.2.1-0ubuntu0.1) saucy-proposed; urgency=low * New upstream release (LP: #1254125) * Update debian/watch * Bump b-dep on libkscreen-dev to (>= 1.0.2) -- Rohan Garg <email address hidden> Tue, 26 Nov 2013 18:01:34 +0100 --------- At logon KScreen restores the monitor configuration that I selected in the previous session. There are still two LVDS screens, but one of them is now disabled at logon. |
