[Bug 840974] Re: configuration of external monitor on laptop does not work properly
Thanks for attaching the dmesg output with debugging turned on. Looking through it I do notice this bit which looks possibly complicit in this issue: [ 515.630872] [drm:intel_prepare_page_flip], preparing flip with no unpin work? [ 515.683339] [drm:intel_wait_for_vblank], vblank wait timed out [ 515.683439] [drm:drm_crtc_helper_set_config], [ 515.683445] [drm:drm_crtc_helper_set_config], [CRTC:4] [NOFB] [ 515.683457] [drm:drm_crtc_helper_set_config], [CONNECTOR:5:LVDS-1] to [CRTC:3] [ 515.683463] [drm:drm_crtc_helper_set_config], crtc changed, full mode switch [ 515.683468] [drm:drm_crtc_helper_set_config], [CONNECTOR:11:VGA-1] to [NOCRTC] [ 515.692792] [drm:intel_crtc_cursor_set], [ 515.699776] [drm:i915_get_vblank_timestamp], crtc 1 is disabled [ 515.716486] [drm:i915_get_vblank_timestamp], crtc 1 is disabled [ 515.733167] [drm:i915_get_vblank_timestamp], crtc 1 is disabled ... Those crtc 1 disabled messages go on for almost 20 seconds, so I presume this sequence corresponds to when your screen was blanked. Looks like at that point the LVDS was mapped to crtc 3; perhaps X was expecting it on crtc 1 instead and started issuing the warnings when it didn't find it there. Would you be willing to do a quick check that this same behavior occurs in Ubuntu Precise? It should be sufficient to boot a Live USB session, configure the monitors, and see if it is working properly now.You can get the current Live USB desktop image at http://cdimage.ubuntu.com /daily-live/current/ and create a USB boot drive using usb-creator. ** Changed in: xorg-server (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/840974 Title: configuration of external monitor on laptop does not work properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/840974/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

if the xrandr command line calls trigger the issue it seems part of the bug is due to xorg itself or the driver ** Also affects: xorg-server (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/840974 Title: configuration of external monitor on laptop does not work properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/840974/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 840974] Re: configuration of external monitor on laptop does not work properly
The problem occurs both using an external monitor (Acer AL1715) attached to my laptop and using only the laptop monitor. When I try to change resolution from 1366x768 to 800x600 or 1024x768, the screen goes black, after about 20 seconds the screen goes back to the original 1366x768 resolution. Tha log file attached in #6 was made using my laptops monitor (my laptop is a HP G-62). Must I send you the same log with the external monitor attached ? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/840974 Title: configuration of external monitor on laptop does not work properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/840974/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 840974] Re: configuration of external monitor on laptop does not work properly
As asked on #5 I tried to use this command: xrandr --output LVDS1 --mode 1024x768 and this one xrandr --output LVDS1 --mode 800x600 But when I launch these commands from a terminal, the screen goes black, I tried to wait for about 2 miniutes, but seeing nothing happen, I typed in CTRL+ALT+F1 and then CTRL+ALT+F7, doing this I get the resolution I typed in the command line ( 1024x768 in the first command an 800x600 in the second). But if I go back to 1366x768 using the monitor settings in system settings and try again to change to 1024x768 or 800x600 I get the same problem, the screen goes black for about 20 seconds and comes back to 1366x768. ** Changed in: gnome-control-center (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/840974 Title: configuration of external monitor on laptop does not work properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/840974/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Is that still an issue? Could you create gsd-debug-randr file in your user directory, restart your session, change the screen settings and copy the gsd-debug-randr.log which got create in your user directory to the bug? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/840974 Title: configuration of external monitor on laptop does not work properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/840974/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Could you also give details about what screen you try to configure, their resolution, placement, etc?

Hello, I've just reproduced the problem with xdiagnose. I'm attaching the second dmesg. Let me know if everything is ok.

Turn on display debug information by running sudo xdiagnose, clicking the first checkbox, apply, then reboot. Now collect dmesg output, then reproduce the problem and collect a second dmesg. You want the data that's in the second dmesg but not the first.
