Steve, there is a known (and fixed in 3.9) bug in the kernel as well with exactly the same symptoms. ** Changed in: linux (Ubuntu) Status: Invalid = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1155838 Title: raring: corrupted display on LVDS when I disconnect my HDMI output To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1155838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1155838] Re: raring: corrupted display on LVDS when I disconnect my HDMI output
But this bug report is not about an arbitrary set of bugs that produce the same symptoms; it's about corruption seen on *my* laptop, corruption that did not clear up when I tested the kernel fix - which is why I un- duped this bug from bug #1157678. It *is* fixed with the current version of xserver-xorg-video-intel in raring. So as far as I'm concerned, the issue is resolved, and keeping a task on the linux package open on this bug is of no help to anyone. ** Changed in: linux (Ubuntu) Status: Confirmed = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1155838 Title: raring: corrupted display on LVDS when I disconnect my HDMI output To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1155838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The patch listed as a fix for this issue in the upstream bug has been uploaded for ubuntu raring. Since it sounds like that should fix this issue I'm closing this bug. If it proves to still be reproducible, reopen the bug. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Fix Committed = Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1155838 Title: raring: corrupted display on LVDS when I disconnect my HDMI output To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1155838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1155838] Re: raring: corrupted display on LVDS when I disconnect my HDMI output
regarding comment #3 from Bryce, the monitors.xml is not an issue here;
I've moved this aside and still been able to reproduce it, and I've
reproduced this also with a completely clean guest account.
It is not specific to the mainline kernel; it's reproducible both with
the raring kernel and with the other (Ubuntu) test kernels I was
running.
I'm attaching two files, xrandr-good.txt and xrandr-bad.txt, for xrandr
--verbose output with and without corruption respectively. In the 'bad'
case, the corruption appears on the HDMI output - but this is not always
true; it may appear on one output or the other.
I can't say I see anything that points to this being a gnome bug, as I
can reproduce the problem when calling xrandr directly to set the mode
('xrandr --output LVDS1 --pos 1680x0').

[Bug 1155838] Re: raring: corrupted display on LVDS when I disconnect my HDMI output
First of all, you can get rid of your xorg.conf, or simplify it down to just the DontZap option. All of that should be irrelevant to this problem, but may as well exclude it. Next, your MonitorsUser.xml looks a bit odd; the last config (which I assume is the one gnome is using for your HW since it's the only one with HDMI1) is missing configuration details on LVDS1. So, I'd try removing monitors.xml and reconfiguring in gnome. See if it generates the same (I guess invalid?) config. The thing to do here is to study xrandr --verbose output before and after the hotplug event. The attached xrandr data I guess is from with the HDMI1 connected: HDMI1 connected 1680x1050+0+0 (0x4c) normal (normal left inverted right x axis y axis) 473mm x 296mm LVDS1 connected (normal left inverted right x axis y axis) When the laptop's in the broken state, check what the xrandr output looks like. I notice you're running a non-standard kernel. Assuming this issue is a regression and not just a misbehavior you've had but haven't noticed, then that kernel would probably be the first thing to look at (i.e. try a different kernel version and see if it reproduces). All the modesetting is done in the kernel so bugs relating to monitor output often arise from that. I've added a kernel task. However, this actually feels more like a gnome bug. gnome-settings- daemon (or rather, libgnome-desktop) is what handles the hotplugging event and what remaps crtcs to appropriate outputs. Turn on verbose debugging for that and collect the debugging output before/during/after the hotplug event to see exactly what xrandr events are occurring. That shows what CRTCs are being mapped to what outputs. Often with these types of output goes missing and just displays corruption issues, the wrong crtc is mapped to the wrong output device. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1155838 Title: raring: corrupted display on LVDS when I disconnect my HDMI output To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1155838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
