[Desktop-packages] [Bug 1263681] Re: 8086:0126 [Lenovo a ThinkPad X220] DisplayPort-2-DVI not hotplugging
A simpler workaround: pressing Fn-Home/Fn-End (screen brightness control keys) after plugging in the DisplayPort cable also triggers detection. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1263681 Title: 8086:0126 [Lenovo a ThinkPad X220] DisplayPort-2-DVI not hotplugging Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: WIth my Lenovo ThinkPad X220 I am unable to hotplug a DisplayPort-2-DVI cable, plug the DVI end into a monitor (Samsung SyncMaster 193p+), and plug the DP end into the ThinkPad, and it is detected within a reasonable time, with GNOME automatically extending my desktop. If I *unplug* the DP cable, the unplug is detected instantly. I once waited ~5 minutes without running xrandr, and it actually detected the monitor and reconfigured.

Chris Wilson said this on IRC: The issue is that after the hotplug interrupt is sent by the hardware, the monitor is not yet ready to respond to the DDC probes and generates a NAK instead - this leads us to conclude that there is nothing on the other end of the connector so it looks like a genuine upstream bug in the Intel graphics kernel driver. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1263681 Title: 8086:0126 [Lenovo a ThinkPad X220] DisplayPort-2-DVI not hotplugging Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: WIth my Lenovo ThinkPad X220 I am unable to hotplug a DisplayPort-2-DVI cable, plug the DVI end into a monitor (Samsung SyncMaster 193p+), and plug the DP end into the ThinkPad, and it is detected within a reasonable time, with GNOME automatically extending my desktop.

[Desktop-packages] [Bug 1263681] Re: 8086:0126 [Lenovo a ThinkPad X220] DisplayPort-2-DVI not hotplugging
Tried talking about this on IRC (#intel-gfx on FreeNode). It was suggested to me to capture the kernel log after setting drm.debug to 0x5. That produced quite a lot of log output (70 thousand lines in about a minute), and after some trimming I got something that could perhaps be useful: https://gist.github.com/mgedmin/8686551 This is me unplugging the DisplayPort connector: Jan 29 13:49:59 platonas kernel: [ 2041.110857] [drm:i915_hotplug_work_func], running encoder hotplug functions Jan 29 13:49:59 platonas kernel: [ 2041.110861] [drm:i915_hotplug_work_func], Connector HDMI-A-1 (pin 4) received hotplug event.

I didn't have a DisplayPort cable before. I used an analog VGA cable and hotplug detection worked reliably. I could boot a 12.04 LTS LiveCD and test it, if it's important. I'd like to help debug this. It would help if I knew how hotplug detection is supposed to work, and what tools there are for me to see where it gets lost. Does the Intel video kernel driver do the detection? Does it poll or wait for an interrupt? How does the kernel communicate hotplug events to userspace? What tool do I run to watch for those events? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1263681 Title: 8086:0126 [Lenovo a ThinkPad X220] DisplayPort-2-DVI not hotplugging Status in “xorg” package in Ubuntu: Incomplete Bug description: WIth my Lenovo ThinkPad X220 I am unable to hotplug a DisplayPort-2-DVI cable, plug the DVI end into a monitor (Samsung SyncMaster 193p+), and plug the DP end into the ThinkPad, and it is detected within a reasonable time, with GNOME automatically extending my desktop.
