One remaining problem with Timo's kernel is that Fn-F7 does not work, which amongst other things means if the laptop ever gets confused with the internal display off there is no escape other than hard-rebooting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745112/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

One other issue (though it might be compiz rather than the kernel) is that after ejecting and then re-docking I'm left with a screen that's totally blank aside from a mouse cursor. The cursor moves with the mouse and it actually changes shape from arrow to I-bar to finger as I move around, suggesting the windows are still there, but the lights are out. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745112/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Here's a newer kernel with just one commit backported. It seems to make things more or less functional on a sandybridge system, so please try it out to see if there are regressions to the stock natty kernel, or to the one with more backported stuff: http://people.canonical.com/~lexical/bugs/lp791752/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745112/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I installed the kernel posted by Timo, and so far I am pretty happy with it. Let me test it for a few days, though: on my machine (thinkpad t410) these crashes are a bit erratic. This is what I tested so far: Booted docked - correctly shows both LVDS and external monitor undocked - correctly updates monitors to display only LVDS re-docked - updates and shows both LVDS and external monitor suspended docked, undocked, resumed - black screen. fixed by switching to console and back suspended undocked, docked, resumed - shows both LVDS and external monitor correctly. I'll let you know if the fix is really stable.

On my x220, I would agree that Timo's kernel is at least as good as any of the others I've tried (Martin's, 3.0.1.2 from oneiric). Suspend and resume works. Trying to enable both monitors leaves large black areas that are not drawn into, but I think that might be a unity problem.

The one thing which is still troublesome is disconnecting the external VGA while suspended, leaving the internal display blank on resume. However this was always flaky in maverick, and is easily fixed by switching to a text console and back.

I'm still curious why it would be that the issue isn't present in a clean install of Xubuntu 11.04, but is a problem with Ubuntu 11.04, Fedora 15, and Linux Mint 11.

I'm running up-to-date Natty. If I boot the laptop with it already docked, everything works perfectly: the two external monitors are used and I get a nice unity desktop spanning my 3840x1200 space. However, if I boot with the laptop undocked, log in, and then dock the laptop, it breaks pretty badly.

I spoke a bit too soon. Timo's branch is a bit better in that the external display works, but not quite right. Some observations: * booting with the external display connected shows the boot and login screens on both, and then my session comes up only on the external display * I can use the monitor preferences panel to reconfigure them * Fn-F7 has no effect (istr we discussed on irc that this was fixed by something else in .39) * If I disconnect with the display already set to internal only, it's ok * If I disconnect the laptop (either the dp cable or from the base) with the internal display turned off, it does not turn back on and (per above) I can't bring it back on with Fn-F7, nor by switching to vt1 and back * On resume from suspend, neither panel shows anything.

I have been bothered by this flickering and automatic display switching issue since installation of Natty (also previously when i upgraded from Maverick to Natty). I am glad to find this bug here, and tried some of the proposed solutions (mainline, backport to maverick). None of them really works for me. My setup is as follows: I have a T410s running natty fresh installed. At office i have an old dell Fp2001 and a mini dock 3, at home a Samsung 225BW without dock. I realise with the office setting i do not seemed to have the issue at all, but only at home i experience the switching(flickering) and crash if i attempt to FN-F7 for a few times. Now the only setup that somehow works is - maverick kernel 2.6.35-02063513-generic from mainline kernel, and with compiz turned off then the system somehow works. When i have time i will try the 2.6.35-22 (which should be the 2.6.35-4 in mainline i suppose?) and see if that helps me. My suspicion is: the kernel attempt to detect the connected external monitor, but due to some unknown reasons, it made the decision that the monitor is missing (due to weak signal via the cable or refresh rate?) therefore attempt to automatically change back to internal display. And if only external monitor is selected, then the flickering mode is selected. hope my report and experience here helps a little. I have no idea about the bisection thing - if it is not too difficult or time consuming i am willing to help perhaps next week. thanks. regards, wahlau -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

To re-emphasize what I said in comment #28: The next step for this bug is that we need to narrow down what patch in the upstream kernel provides the fix. The best way to achieve this is via doing a git bisection search. See https://wiki.ubuntu.com/Kernel/KernelBisection. From the comments it sounds like three things are needed: * The mainline kernel .39 * Delete your .config/monitors.xml * Don't arrange monitors one above the other (interesting; why? maybe unrelated bug?) None of us X devs have arrandale HW, so progress on this bug is blocked until someone who *does* have it can do the git bisection work to narrow the patches.

@Bryce: According to that page, Required knowledge and tools The rest of this page assumes that you know how to fetch a kernel from the Ubuntu git repository, and build it, and that you have basic git skills. If you can't do that yet, try starting with this wiki page. So there's the fundamental stumbling block for most users. I can probably figure it out, given a bit of time, although I haven't had to go bug-hunting in the kernel since 0.9-something. Also, I do not know of a working kernel version that I can use to narrow it down. This laptop has only ever run 11.04, so far... I have no idea what effect downgrading to 2.6.35-22 will have on this system. And, of course, I really have no great galloping desire to burn a day or two doing kernel rebuilds.

Intel D820 here with Intel Mobile GM965/GL960 Integrated Graphics Controller. I use a docking station with two identical HP LA1951g monitors attached, one VGA, one DVI with a native resolution of 1280 x 1024 @ 60 Hz.

Even when docked and with the lid shut, the laptop still displays on the LVDS only (?!?) - and with a weird resolution too. Attempts to shut off the LVDS and force image on the external display leads to black screen on all three of them followed by a system freeze (CTRL+ALT+POWER is the only way to reboot it).

[Bug 745112] Re: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64)
** Description changed: Binary package hint: unity (I'm not sure where in the stack this problem really is, so I'm guessing and picking on unity) I have a Lenovo T410s laptop with Intel graphics and I use it with a dock with two 1920x1200 monitors connected. I'm running up-to-date Natty. If I boot the laptop with it already docked, everything works perfectly: the two external monitors are used and I get a nice unity desktop spanning my 3840x1200 space. However, if I boot with the laptop undocked, log in, and then dock the laptop, it breaks pretty badly. Only one monitor is lit up, and I just get a black screen with a mouse pointer there -- no desktop background, windows, toolbars, or anything. Once it's in this state, it doesn't seem possible to recover -- if I undock the laptop again, the internal screen just stays black with a pointer. When the laptop is in a working state, undocking it sort of works... the desktop switches to the laptop screen, but then redocking it acts just like docking as described above.

On lp #747205 we discovered by creating a new user account, that having certain RANDR operations present in monitors.xml would trigger it, presumably because gnome-settings-daemon would pick up those configuration settings and try applying them, triggering an underlying bug in RANDR. Perhaps fiddling with the primary monitor setting did it? 734756 collected register dumps on the issue, and experimented with some dpms forcing from the userspace side. My elderberry PPA was found to have some positive effects, but didn't fix it sufficiently completely to warrant pursuing that to work around the kernel issue. drm-intel-next- proposed did not boot on this reporter's hardware. Video and photos are available on bug #750259. We also examined gpu error states and found this bug is not a gpu lockup issue (as 747205 suggested). The drm-intel-next-proposed kernel from around 4/21 was found to fix it. Bug #737891 includes reports of this issue, among other problems. Maverick was re-tested via livecd and the issue was not reproduced (maybe for the same reasons as creating a new account in bug 747205 did not reproduce? Reporters also found that deleting monitors.xml has an ameliorative effect.)

That should capture all the background on the various instances of this bug that I've been working with people on. Basically, there are some variations in symptoms but all of the reports are particular to Arrandale, occur in relationship with setting up external screens (perhaps something relating to primary monitor settings), and appear to be fixed in the latest kernel. The next step for this bug is that we need to narrow down what patch in the upstream kernel provides the fix. The best way to achieve this is via doing a git bisection search. Unfortunately none of us Ubuntu-X guys have Arrandale hardware, so if this bug is going to get fixed in natty we need a volunteer to do this.

An alternative thing to investigate: There is another bug particular to Sandybridge, with roughly similar symptoms to this one, which has already been git bisected and found a candidate patch. The flagged patch with the fix appears to also affect Arrandale, so I have a hunch it *might* also solve this bug. But that's just a wild guess.

I was having a very similar issue with a thinkpad X201 (see https://bugs.launchpad.net/bugs/771344 - which is now duped here) However, booting with the monitors plugged in made no difference - I would go to the black screen regardless when I logged in an existing account. However, a freshly created account was able to display two monitors and worked OK with monitor connects and disconnects. I removed all the compiz files from the existing account and then logged in with a classic no affects session. This gave me black screens, but I was able to hit fn-f7 and my screens cycled through various combinations. Some of these were all black, but some worked, including both screens full resolution (not mirrored) and just external monitor. I was then able to log out and back in with a classic with effects session, and this now works! However, if I fn-f7 too much, then eventually I end up in the black screens with only X cursor situation and have to restart X to get out of it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Roland, that's a good eye. It is the kernel modesetting portion of the stack which allocates framebuffers, and that does tend to indicate where in the core logic things may be going awry.

In addition to testing the .39-rc kernel, you can test Intel's experimental tree which we package for Ubuntu now for testers: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next-proposed/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 745112] Re: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64)
Roland, thanks for that. Alright, here is what I think is happening. Arrandale graphics cards have a hardware limitation of a max texture buffer size of 4096x4096. What this means is that compositing will work only if the total screen width is 4096 or less. Over that, and the GPU can lock up or other weird things can occur. My hypothesis is that when you are booting with the laptop docked, the internal laptop LVDS panel is disabled, so your total width is 1920+1920 which is 4096. However, when you boot with the laptop panel on and *then* dock, the kernel is adding the two monitors to the left or right of the laptop panel, resulting in 1920+1920+1440 which is 4096. Looking at your monitors.xml, the first section shows HDMI2 and HDMI3 arranged side-by-side, and LVDS1 is also present and not disabled but not set to any particular position, so it is unclear how the kernel would position it in this case; perhaps it is adding it at +3840+0 which would fit with my hypothesis. There are a few things you could test which might prove my hypothesis wrong: a. This behavior should occur only with Unity/Compiz. If you boot Classic Desktop (No Effects), the system freeze should be unreproducible. (However, see below) b. If in gnome-display-properties you arrange your LVDS to be positioned *below* your two main monitors, it should work in unity. Note you may need to delete your monitors.xml before making these settings. c. If you disable your LVDS before docking (either using the GUI, or via 'xrandr --output LVDS1 --off') and then docking, the system shouldn't freeze. (I don't know if the external monitors will fire up in this case, but at least it won't trigger the freeze bug). These may also give you some idea on working around the issue. If those tests turn out correct, then this issue is basically a sub-case of bug #555641. However, I think that there could be some work done in gnome-display-properties to check max texture size before enabling configurations like this, if compiz is running. Now, one other caveat. It appears that there is a separate unrelated bug that is common to Arrandale, that certain RANDR operations can sometimes result in a monitor being improperly blanked. So, that may add some confusion to your testing. But the way to tell these bugs apart is that your original bug results in a system lockup (a black screen with a mouse pointer, and no way to recover), whereas with this latter blanking bug, you won't see a mouse cursor and the monitor will appear to be not getting any signal. Possibly you may be able to work around this blanking issue via this command: xset dpms force on Anyway, sorry for the lengthy dissertation, but hopefully with this information you can help me nail down this bug. I have some thoughts on what steps to take to get resolution to this issue (and the blanking one) but let's see if you can prove my hypothesis before we get into all that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Bruce, thanks for all the info. I will do some more testing today. One clarification though: when I get in the black screen + mouse pointer situation, my machine is not hung. In fact the mouse pointer is still responsive, I can log in via network, etc. It just that I lose the X root background, WM stuff, etc. Also I believe I did see similar problems with classic, although I need to double check the no effects part. I definitely have seen it from the GDM screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Bryce, first off, sorry for mistyping your name ;) I did a bit more testing, and I tried the classic/no effects login again. If I start undocked and dock, I do get the black screen/responsive mouse pointer. However, if I log in with classic/no effects *and* do xrandr --output LVDS1 --off and then dock, one monitor lights up with a real desktop (ie it seems to work). The second monitor was off, but I was able to get it to light back up by going to a text console and back to X. (I guess this is the second conflating bug you mentioned). I tried a standard unity login and did the xrandr --output LVDS1 --off and I still ended up with a black but on monitor. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Roland, thanks for the quick response. Regarding your clarification, yes despite how it may seem, blank screen with moving mouse cursor and X not responding to input, but network login works is the prototypical set of symptoms that go with a GPU hang. The kernel itself is ok, which is why you can ssh in; the mouse cursor is handled far enough outside the core of X that it is often unaffected by lockups (not always though). Often when you have a GPU lockup, there will be an error message in your 'dmesg' output. The file /sys/kernel/debug/dri/0/i915_error_state often displays error codes when the GPU is locked up. In fact, if you could reproduce the bug with the classic/no-effects case and attach both of those here, it might give us some more clue what's going wrong. Or, at least, it gives me plenty of info to take upstream. Regarding the second conflating bug (which I suspect might be a DPMS bug in the kernel's arrandale code), I've a PPA you could try to see if it at least improves that situation: https://launchpad.net/~bryce/+archive/elderberry -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I added that ppa and updated, and did a bit more testing. It seemed to work a bit better, though not in the way I would have expected. classic/no-effects: I started undocked, and actually got docking once to work perfectly (both monitors lit up, desktop displayed on both). However when I undocked and re-docked again, my right monitor didn't light up (although I got my desktop on the left monitor). I was not able to get the right monitor to turn on again, after trying xset dpms force on , the gnome monitor GUI, going to tty1 and back, etc. This situation was stable after a couple more undock/redock cycles. I never got into the black screen/moving mouse pointer situation. The kernel log never showed any intel graphics related stuff (just USB devices appearing/disappearing and other docking related stuff). And i915_error_state stayed no error state collected. unity: Again I actually got docking to work once; however the second time I docked, I got the black screen/moving mouse pointer and right monitor stuck with no signal. However neither the kernel log nor the error_state file showed anything. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 745112] Re: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64)
I just noticed something while looking at my Xorg.0.log after a couple of dock/undock cycles leading to the black screen. I'm attaching the full log, but what I noticed was: boot up undocked: [ 5.897] (II) intel(0): Allocated new frame buffer 1472x900 stride 6144, tiled matches a 1440x900 panel dock: [ 370.652] (II) intel(0): Allocated new frame buffer 3840x1200 stride 15360, tiled makes sense, I now have 2x1920x1200 monitors undock: [ 414.405] (II) intel(0): Allocated new frame buffer 1472x900 stride 6144, tiled back to the 1440x900 panel dock again: [ 434.873] (II) intel(0): Allocated new frame buffer 1920x1200 stride 7680, tiled now it only allocates a buffer for one monitor -- which probably explains why the second monitor never lights up I'm not sure what layer of the stack is responsible for figuring out what buffer to allocate etc but this does seem like the first real clue I've seen to where the problem lies. ** Attachment added: xorg.log https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745112/+attachment/2071439/+files/xorg.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
