Description Diego 2010-11-08 17:12:32 UTC
Version:           unspecified (using KDE 4.5.2) 
OS:                Linux

When I try to resize my panel on an external monitor with a different resolution the maximum allowed with is not the one of the monitor. This worked up to 4.4.5 and broke when I upgraded directly to 4.5.2 on Fedora 13.

Taking a look at the code of the panel the size is taken from Kephal. I've seen that commit #1114469 changed a lot of how screen resolution is detected from 4.4 to 4.5 series.
http://websvn.kde.org/?view=revision&revision=1114469

Reproducible: Always

Steps to Reproduce:
1) get two monitors with different native resolution
2) move the panel on the one with the bigger resolution
3) use the option to maximize it

Actual Results:  
Panel resizes to min(width_monitor_1, width_monitor_2).

Expected Results:  
Panel resizes to max(width_monitor_1, width_monitor_2).

I'm going to attach some useful informations...

Still present in 4.6.x but I've found a manual workaround: open panel settings, drag the panel into another angle and back to the bottom and the ruler to set the size will be as large as the screen width (unlike attachment #53251 [details] ).

Thank you for your bug report or feature request.

Unfortunately, we did not have a maintainer for the "kephal" component, which is used to manage displays and monitors in the KDE Workspaces.

The "kephal" component has been superseded by "KScreen" in newer releases of the KDE Workspaces. It is compatible with all versions since 4.11, and is also used with Plasma 5. Please check with your distribution how to update to KScreen.

If this issue or feature request is still applicable to KScreen version 1.0.5 or newer, please add a comment. We will then reassign this ticket to KScreen developers.

If you are already using KScreen to manage displays or monitors, and found a different bug or need a specific feature, please create a new ticket for "KScreen" product in this bugzilla using this link: https://bugs.kde.org/enter_bug.cgi?product=KScreen
