[Bug 1275794]
So, to my understanding MST is not supported meaning that multiple (DP) connected monitors will become mirrored. However, it seems like also the DVI output is mirrored - is this expected? I am running Ubuntu 14.04 (i.e. 3.13.0-24-generic) on a T440p attached to an ultra dock (firmware 2.17), and attaching one DP monitor works flawlessly together with the builtin display. However attaching an additional monitor (occurs for both DP and DVI) simply mirrors the first DP connected display. xrandr outputs the same in either case: martin@martin-ThinkPad-T440p:~$ xrandr Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 32767 x 32767 eDP1 connected (normal left inverted right x axis y axis) 1600x900 60.0 + 1440x900 59.9 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x60060.3 56.2 640x48059.9 VGA1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP2 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 60.0*+ 3840x1200 60.0 2560x1024 60.0 1920x1080 60.0 1600x1200 60.0 1680x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x800 59.8 1280x720 60.0 1024x768 60.0 800x60060.3 640x48060.0 720x40070.1 HDMI2 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) I would expect the DVI port to be working independently of the DP port - is this not the case? thanks, Martin -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1275794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1275794] Re: Lenovo T440s freezes when connected to docking station
I confirm this behaviour: with the dock firmware update (T440s in a ProDock for me), I can use external displays. I can have two external displays (two 1680x1050), one on HDMI port, an another on VGA port. In normal mode, the two external displays are mirrored. But I can put them in extended desktop mode and have something like one 3360x1050 display. I'd preffer have two distinct displays, because today it's difficult to manage the windows size of the graphic applications (in particular, the automatic resize facility when you push the window to the bottom/top/left/right on in the corner). So, I expect an evolution. Nevertheless, the good news is that I can use 3 displays in the same time: the internal one and the two externals. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1275794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We had a bug in the driver, and thanks to this bug report it's now fixed. Everyone, thanks for the report and testing! I hear a firmware upgrade in the dock also fixes the issue, but it doesn't mean we didn't have a bug. As the fix ended up being my commit, I feel I should express my view on the offered bounty. This is speaking solely for myself, not for my employer or colleagues. Regardless of the firmware fix, I think it would be unethical of me to accept any part of the bounty. I am employed to work on the driver, and fixing issues like this is part of the job. Personal prize money should not directly affect, or give an impression that it would affect, the priorities I set and am given as an employed developer. This is also a team effort. I contributed the fix, but many developers were involved in the triage, and people who tested the patches likely spent more time on this than I did! (Thanks again!) All that said, I appreciate the offer and FreedomSponsors in general, and I would have no qualms about accepting bounties for things I work on in a hobbyist capacity.

I have exactly the same issue on Ubuntu 14.04 with an T440s which makes its display connection via the docking stations Display Port. After I patched the Kernel with Stefan Agners link-train-delay.patch and now it works reasonably well, the time it takes to make the display connection for me is about 10 seconds at max, which is acceptable for me.

I tried applying the patch ([PATCH]HDMI connection via dock works with some (random) delay: https://bugs.freedesktop.org/attachment.cgi?id=93653) against a 3.13 kernel, and it makes things **worse** on my T540p. With the 3.13 kernel w/o the patch, I can boot and start up the X server w/o problems, as long as it is not docked. With this patch, the system locks up very early in the boot process, as soon as the console switches from the compat VGA mode into the higher resolution console mode). Also, when comparing an unpatched 3.12 kernel with an unpatched 3.13 kernel, 3.13 is also worse with the T540p. With the unpatched 3.12 kernel, I can have the laptop in the dock, and so long as there are no external monditors hooked up via the dock video connectors, it worked fine. With the unpatched 3.13 kernel, it's fine outside of the dock, but if it is in the dock, even if the dock does not have any external video monitors hooked up, any time there is any change to the video setup (i.e., X server starts up, DPMS puts the monitor to sleep, etc.) the system will lock up. It will recover after I eject the laptop from the dock, and after that point I can redock it, but while the system is locked up, the laptop heats up and the fan starts up --- which I suspect means that we are indeed hanging in some spinlock. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1275794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Jani, for the record, I did my tests with your two patches before I updated the dock firmware, and it definitely did make the hangs go away --- and as I mentioned, I was even able to connect to an external Dell LCD panel using DP without any problems (although the too many retries debug message did trigger).

If you'd like me to do some testing of the new code with a buggy dock, I'm happy to keep one of my docks at the old firmware version, especially since the two patches seem to be an adequate workaround. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1275794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

(In reply to comment #115) I tried applying the two patches which you posted on intel-gfx[1], ported to 3.13. [1] http://article.gmane.org/gmane.comp.freedesktop.xorg.drivers.intel/33737 Using a T540p and an Ultradock, connected to a Dell U2410 via a DisplayPort cable --- and it worked! Not only were there no hangs, but in fact I could enable and disable the external display. The too many retries did indeed trigger: These patches did not work for me with my T440s. During bootup it hangs upon switch to FB. Once booted undocked, it hangs when docked and external monitor is enabled through xrandr. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1275794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1275794]
I have a W540 that also freezes when trying to use DP, with the difference that I don't see any oops or error message in neither the kernel logs, nor the X logs. When I plug in an external monitor, xranrd shows it as connected to DP2, regardless of whether it's connected to DP1, DP2, DVI or HDMI. On one occasion, I have been able to get a mirror output on both DP1 and DP2 (still after 1-2 min of freezing), even though xrandr still showed only DP2 as being connected. I have been unable to reproduce that partial success since. During the freeze, Xorg keeps using a steady 20% CPU, but any attempt at attaching gdb to the Xorg process only resulted in gdb feezing (had to kill -9 it).

[Bug 1275794] Re: Lenovo T440s freezes when connected to docking station
apport information ** Tags added: apport-collected ** Description changed: This bug report looks to be for the same issue: https://bugs.freedesktop.org/show_bug.cgi?id=71267 I came across the above bug report here: https://bbs.archlinux.org/viewtopic.php?pid=1374408 I'm running with a Thinkpad T440s and ultra dock with hdmi-hdmi. In my case if I dock when hdmi is connected to the dock, the mouse and keyboard freeze once connected. When I undock they unfreeze. If I dock when hdmi is not connected to the dock, the mouse and keyboard don't freeze.
