    [Xubuntu] X.org configuration lost i915/nvidia - SystemIO conflicts with Region

    Yesterday I did install some updates for packages, including i915 libs. For some reason now my x configuration is completely gone, even if I restore it from backup, it resets back to default configuration. I checked dmesg but I don't see anything strange there. Ubuntu tried to send report about i915 package, but failed because it's not official package.

    Is anyone else experiencing same problem(s)?

    - Thank you

    Yes, I have four displays and two display adapters and my config is really complex. That's one of thre reasons it's harder to debug. Any great hints where I should start? Dmesg doesn't show anything interesting.

    Hmm, syslog showed this. Maybe this is the reason? But it's for Nvidia module.
    Code:
    Sep 23 21:13:25 zender kernel: [    1.384701] nvidia: module license 'NVIDIA' taints kernel.
    Sep 23 21:13:25 zender kernel: [    1.384704] Disabling lock debugging due to kernel taint

    Re: X.org configuration lost i915/nvidia - tainted kernel?

    I rechecked all logs, this is only indication of some problems. Is this a real problem or not?

    Code:
    [    1.404933] nvidia: module verification failed: signature and/or  required key missing - tainting kernel
    [    1.407757] ACPI Warning: 0x0000000000001828-0x000000000000182f SystemIO conflicts with Region \PMIO 1 (20131115/utaddress-251)

    Fresh dmesg log after re-installing Nvidia drivers. Now there's at least clear error message.

    Code:
    [    2.698382] nouveau  [     DRM] Load detected on output B
    [    2.698550] nouveau  [     DRM] allocated 720x576 fb: 0x9000, bo ffff8802426c8400

    [    2.742504] NVRM: This can occur when a driver such as nouveau, rivafb,

    [    2.742506] NVRM: Try unloading the conflicting kernel module (and/or
    [    2.742506] NVRM: reconfigure your kernel without the conflicting
    [    2.742506] NVRM: driver(s)), then try loading the NVIDIA kernel module
    [    2.742506] NVRM: again.
    [    2.742507] NVRM: No NVIDIA graphics adapter probed!

    Any ideas how to fix this? Or do I really need to rollback i915 and kernel, or am I doing something really wrong? Intel driver seems to be working with right resolution until I login, after login I guess some configuration really throws things off and resolution drops and adapter now shows tow screens on one screen, leading to situation where top and bottom menu bards actually cover only half of the screen. This is so weird.
