Description Erik Quaeghebeur 2013-05-09 11:01:42 UTC

Regarding the version: I don't know exactly: I've installed it (yesterday 8 May 2013) using the Gentoo live ebuild (the only ebuild available), which normally builds from git head.  The only identifying info I could find is that I have /usr/lib64/libkscreen.so.0.0.92 installed. I may be able to determine the exact commit with instructions.

My setup: Laptop with dock, internal screen is 1366x786, external screen is 1080x1920 (so 90° rotated 1920x1080); only one of both is used at any time.

When I unplug the external monitor, the internal one activates correctly. When I reconnext the external one, it is activated, but at resolution 1080x786 (I think) at the top of the display, so the bottom 1100-something pixels are black (well, on one occasion there was garbage there) and I can't go there with the mouse; the limited viewport works without problems.   

So I have (external 1080x1920) - disconnect -> (internal 1366x786) - reconnect -> (external 1080x786), whereas the last should be (external 1080x1920), of course.

Reproducible: Always

Steps to Reproduce:
1. disconnect external display
2. reconnect external display
Actual Results:  
incorrect resolution on external display

Expected Results:  
correct resolution on external display

Let's fix this.

1-Execute kdebugdialog
2-enable ëverything with "kded" and "ksrandr"
3-kquitapp kded4
4-kded4 (in a terminal)

Paste here the output of that process.

Thanks !

Ok.

> 2-enable ëverything with "kded" and "ksrandr"

Ok.

> 3-kquitapp kded4

`kquitapp kded` instead

> 4-kded4 (in a terminal)

`kded4 2> kded-output.txt` instead 
 
Started with external actve/internal inactive; disconnected external (internal became active with correct resolution); reconnected external (became active with correct(!) resolution).

The problem did not occur! (Close bug as 'problemmagicallydisappeared'? I'll reopen/comment again if the problem resurfaces and I can catch it with the procedure you've described.)
