[Bug 745112] Re: [arrandale] desktop is messed up with external monitors (x86_64)
I'm not sure if I'm in the right place, but on my T61 + docking station I have an issue with desktop files/folders not being displayed correctly. With either VGA or DVI, everything works great but the files/folders in the Desktop/ folder are not constrained to the viewable area. They remain on the laptop monitor (can be dragged to the external monitor) but they are off the screen. Organize Desktop by Name has the same result. So, it seems that the area allocated to icons is bigger than the actual display. -- 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 with external 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

Two things may be going on here: 1) we're setting the DP audio enable bit too early I think; we should only set it when we go to a normal link mode 2) there may not be enough bw for audio at 25x16 with the clock configuration we use, we may need to reduce the audio config somehow Paulo, do you have a DP monitor you can test with to confirm? I just confirmed that 25x16 works fine on my ILK laptop with drm-intel- next-queued, but I don't have any audio in my config.

Current status in Precise seems to be: - works reliably with ` xrandr --output DP1 --mode 2560x1600 --set audio off` - fairly reliably **does not** work if I set the external monitor direct to 2560x1600 from the monitors control panel, I'm guessing because that does auto audio and gets it wrong. ** Changed in: linux (Ubuntu Precise) Status: Fix Released = Triaged -- 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 with external 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 apparently regression in 3.2.0-16.25 (maybe unconnected to this change?) is that fn-f7 does not seem to have any effect. It was working on the previous kernel I tried, both the Ubuntu ones and my own builds. Turning on the external screen with xrandr does work: xrandr --output DP1 --mode 2560x1600 --set audio off --above LVDS1 Using the displays control panel, the first time I tried, the monitor showed an error about the signal being wrong. I've just tried again and it has worked. So, I'm not sure. Also, after using the monitors control panel, Fn-F7 is working again. (So, perhaps the bug is in userspace?)

[Bug 745112] Re: [arrandale] desktop is messed up with external monitors (x86_64)
Hi Martin, Thanks for all the extra testing and feedback. I'd been looking at bug 912387 (fdo bug 44881) in parallel. The patch to fix bug 912387 appears to provide a fix for the issue you are seeing here. I've therefore cherry-pick'ed the patch in question from the drm-intel-fixes branch into Precise prior to the patch officially hitting the mainline kernel. So this issue should be resolved in Precise after the next upload (which I intend to do before the end of the week). I see that the patch has also been CC'd to upstream stable. Once the patch does land in mainline, it'll then propagate through to the upstream stable releases. This means that it should land in Oneiric automatically through our normal SRU process and not require any further action on our part.

[Bug 745112]
Just to be clear: forcing audio off every time the external display is configured, by using xrandr ... --set audio off, does make it work reliably every time so far. What I tested previously, and what did not work to turn it off just once and then use the system's normal configuration method (eg fn-f7), I guess because that is effectively configuring the monitor with auto audio. So it does seem that the problem is related to audio; in my particular situation being able to force it off all the time would at least hide the problem. I don't care about sending audio to my monitor, but I suppose others do, so a patch that just turns it off across the board probably wouldn't be accepted. I guess the next thing to work out is: * audio actually can't work on this channel with this resolution (not enough bandwidth?) * there's a bug in this monitor to do with audio at high resolution? * there's some other bug in the kernel about dp audio? * ...? -- 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 with external 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

[Bug 745112]
It seems like if I force audio off at the same time I add the external screen, through xrandr, it does work reliably(?) so far. Using the monitor control panel or fn-f7 apparently puts audio back to the 'auto' setting, which does induce a problem I tried running for i in `seq 30` ;do; echo i xrandr --output DP1 --off sleep 15 xrandr --output DP1 --mode 2560x1600 --above LVDS1 --set audio off sleep 15 || break;done and this got through 14 iterations successfully. Now I wonder if I can identify what the problem is with audio or provide a way to force it off. This screen does have an option for speakers to be connected, but I'm not using it. I don't know if it picks up audio across dp. -- 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 with external 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
[Bug 745112]
Running xrandr --output DP1 --mode 2560x1600 --above LVDS1 --set audio on when it's previously working does immediately make the monitor black out, and using '--set audio off' does not bring it back, nor does soft power cycling the monitor or unplugging/replugging it. I can see some reports of people complaining about dp/audio problems under windows with the U3011, but it's hard to tell how much they indicate a real hardware/firmware problem vs windows driver problems or something else. http://en.community.dell.com/support- forums/laptop/f/3517/p/19370516/19844480.aspx It seems that the Nvidia based implementation at least with Displayport ++ out will only support an audio signal being passed over displayport to an external monitor that is no high resolution than 1080HD, or 1920x1080.

This bug, or one a lot like it, seems to have regressed on oneiric (3.0.0-11). If I boot up my x201 with the external monitor connected, it normally but not always works. When it comes back from the screensaver, normally the external screen will be blank but switching to vt1 and back does get the screen back (showing the unlock dialog.)

[Bug 745112] Re: [arrandale] desktop is messed up with external monitors (x86_64)
I am using Thinkpad X201 (natty, unity) with docking station and an external monitor attached via DP - HDMI. Note that I have packed all additional files (screenshots, logs) into tar.bz2 attached below. Since I had problems with the external monitor (occasional black monitor on boot ...), I started using Timo's kernel ( linux- image-2.6.38-10-generic_2.6.38-10.44sru1_amd64.deb ). In my setup, the laptop screen is off and all work is done via external monitor. Probably after running the screensaver, the monitor got corrupted with the several regions just shown in black. It seems that during a wakeup, external screen was run as if it is the internal laptop screen. This can be observed on attached screenshots with terminal occupying part of the screen (Screenshot1.png) or maximized ( Screenshot-terminal- fullscreen.png ). On other desktops, all maximized windows were reduced accordingly. Monitor preferences ( Screenshot-monitor-preferences.png ) seem to confirm it; xrandr and dmesg outputs are in xrandr.txt and dmesg.beforexrandr.txt, correspondingly. I managed to fix the problem by running xrandr --output LVDS1 --auto xrandr --output LVDS1 --auto --output HDMI1 --auto xrandr --output LVDS1 --auto --output HDMI1 --off xrandr --output LVDS1 --auto --output HDMI1 --auto xrandr --output LVDS1 --auto --output HDMI1 --auto --primary As a result, I returned to my setup. If I remember correctly, LVDS1 was actually off after running all those commands and looking at 'Monitor Preferences' (Screenshot-monitor-preferences.png). Dmesg after all those commands is in dmesg.afterxrandr.txt . In addition, I have attached part of kern.log from my last boot (first 60s). If the full log is needed (~700KB), it can be downloaded via http://sysbio.ioc.ee/~markov/kern.log.full.bz2 Let me know if I should report this bug somewhere else and if you have any questions. ** Attachment added: monitor_trouble.tar.bz2 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745112/+attachment/2230824/+files/monitor_trouble.tar.bz2 -- 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 with external 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

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

Martin: That is indeed a compiz bug. Fn-F7 not working; weird that for some X201's it does work but not for you. Don't know why.

The black-screen issue has happened more than once, but I don't yet know how to consistently reproduce it. It is different to (though maybe related) to the other issue seen where some regions of the screen aren't drawn correctly. -- 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 with external 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

It worked perfectly in previous Ubuntu releases. It's also worked in some of the kernel I've tried in the course of trying to localize this bug. ** Summary changed: - [arrandale] desktop is messed up (goes black) when laptop is docked with two external 1920x1200 monitors (x86_64) + [arrandale] desktop is messed up with external monitors (x86_64) -- 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 with external 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 tried this on my x201 against an Optoma projector and it seems to basically work. (I'm not at home with my monitor at the moment.) I do see the black areas but I agree that's likely a unity thing, or at least not a modesetting bug.

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. Thanks for the effort fixing this annoying bug. -- 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

using the backport kernel from Timo, with the t410s connected directly to a Samsung 225BW i still get random switching from LVDS alone to dual display. I do see some improvements - my screen do not switch off and on that frequently as compared to default latest kernel, but problem is not solved. -- 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've re-tested with just the one patch as per Timo's comment above; this seems to work just as well for me as my previous test with the additional patches. -- 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
