Bug Description

[ Description ]

The fix for bug #1065979 regresses multi-monitor behaviour for some users.

[ Fix ]

Revert it.

[ Regression potential ]

This will undo any fix for bug #1065979. But we promise that we won't *introduce* bugs in stable release updates, so this has to take priority.

The contributor of the fix to that bug can try again if desired, but probably with an extended ageing period in -proposed.

[ Original report ]


I use Kubuntu 12.04.x with lightdm as login-manager to KDE and the nvidia binary driver with 2 monitors (DVI, TwinView).

My Multi-Monitor config:
right monitor: MAIN monitor
left monitor: second monitor as extension: with mode left of Main Monitor

This config is setup with nvidia-settings, which stores in xorg.conf and in .nvidia-settings in home-dir.
In KDE the config is also stored with krandr as default config.

After upgrading from package gnome-settings-daemon (3.4.2-0ubuntu0.6.2) to gnome-settings-daemon (3.4.2-0ubuntu0.6.3), the xorg.conf settings are ignored/misinterpreted as well as the KDE krandr settings.

When lightdm is started, the second monitor is on the right side, and when logging-in to KDE either clone mode on both monitors is started or the second monitor is on the right side (mirrored).
=> I have to set my desired settings manually again and at the next reboot the problem persists.

I have downgraded to gnome-settings-daemon-3.4.1-0ubuntu1, and the problem is gone. All fine again.

I didn't find the previous version 3.4.2-0ubuntu0.6.2. How can I get this package version?

  * debain/patches/follow-lid.patch:
    - external/internal monitors mirrored on boot when laptop lid is closed

1065979 external/internal monitors mirrored on boot when laptop lid is closed

I use this PC at my workplace, so it is important for me to solve this problem.

Thank you for your help!

Best regards, Bernhard

Can I provide any debugging information?

Yes, please revert LP: #1065979 as it caused a regression:

LP: #1065979 broke the default Xorg resolution,
set by e.g. PreferredMode in xorg.conf or by XRANDR_MODE_0 in LTSP,
now gnome-settings-daemon forces the *highest* resolution instead of the default one.

It's very annoying on CRT screens where e.g. 1024x768 is preferred, and 1600x1200 is unreadable.

Could you please revert #1065979 until it's properly solved?
