[Bug 1578011] Re: Laptop sometimes doesn't detect external monitor when docked
vik: 1) As per the sticker of the monitor itself (not from the Bug Description, or the result of a terminal command), could you please provide the full monitor manufacturer and model? 2) Regarding how you have the monitor connected, is it plugged into the dock's DVI-I, or DisplayPort port? If you switch the port is this still reproducible? 3) Regarding the connection of the monitor to the dock, is this via straight DVI-I cord, using dongle/adapter, etc.? 4) If you instead undock the computer, and plug the monitor directly into the computer, is this still reproducible? 5) Regarding the Lenovo ThinkPad OneLink Pro Dock, have you applied the latest firmware to it? ** Tags removed: latest-bios-1.29 ** Tags added: bios-outdated-1.38 regression-potential ** Attachment removed: "syslog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1578011/+attachment/4780928/+files/syslog.txt ** Changed in: xorg (Ubuntu) Importance: Medium => Low ** Changed in: xorg (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Laptop sometimes doesn't detect external monitor when docked + [Lenovo ThinkPad Yoga Type 20C0] Laptop sometimes doesn't detect external monitor when docked into ThinkPad OneLink Pro Dock -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1578011 Title: [Lenovo ThinkPad Yoga Type 20C0] Laptop sometimes doesn't detect external monitor when docked into ThinkPad OneLink Pro Dock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1578011/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1578011] Re: Laptop sometimes doesn't detect external monitor when docked
A short update on that: I am running 4.4.0-31-generic now, and although i can not see from the changelog what would have changed in that regard, recognizing an external display connected to a docking station is no problem anymore. But after asuspend/resume-Cycle, the internal monitor will not switch on again anymore, and kernel seems non-responding to requests via sysrq. As such, I currently can not help with any kernel output in that case. If you could give me any advice in how to collect kernel output in that case, I'd be happy to deliver it. Attached is a kernel warning, which happens after unplugging from the docking station: Jul 24 21:06:03 synlap01 kernel: [84597.934350] [ cut here ] Jul 24 21:06:03 synlap01 kernel: [84597.934388] WARNING: CPU: 2 PID: 21878 at /build/linux-dcxD3m/linux-4.4.0/ubuntu/i915/intel_dp_mst.c:522 intel_dp_destroy_mst_connector+0xec/0x100 [i915_ bpo]() Jul 24 21:06:03 synlap01 kernel: [84597.934390] Disabling mst crtc failed with -22 Jul 24 21:06:03 synlap01 kernel: [84597.934392] Modules linked in: hid_logitech_hidpp hid_logitech_dj hid_generic usbhid snd_usb_audio hid snd_usbmidi_lib ctr ccm pci_stub vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) ip6t_REJECT nf_reject_ipv6 xt_CHECKSUM ipt_REJECT nf_reject_ipv4 ebtable_filter ebtables ip6table_filter ip6_tables ipt_MASQUERADE nf_nat_masquerade_ipv4 xt_addrtype br_netfilter bridge stp llc aufs iptable_nat nf_nat_ipv4 nf_nat xt_tcpudp nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_conntrack iptable_filter iptable_mangle ip_tables x_tables rfcomm bnep binfmt_misc zfs(PO) zunicode(PO) zcommon(PO) znvpair(PO) spl(O) zavl(PO) arc4 intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp snd_hda_codec_hdmi snd_soc_skl snd_soc_skl_ipc snd_hda_codec_realtek snd_hda_codec_generic snd_hda_ext_core snd_soc_sst_ipc snd_soc_sst_dsp snd_soc_core snd_compress ac97_bus snd_pcm_dmaengine dw_dmac_core joydev input_leds snd_hda_intel cdc_mbim serio_raw iwlmvm cdc_wdm snd_ hda_codec cdc_ncm snd_hda_core usbnet snd_hwdep mii mac80211 btusb btrtl btbcm btintel qcserial usb_wwan bluetooth usbserial snd_pcm iwlwifi rtsx_pci_ms memstick cfg80211 thinkpad_acpi nvram snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq snd_seq_device snd_timer snd soundcore mac_hid shpchp mei_me mei kvm_intel kvm irqbypass parport_pc ppdev lp parport autofs4 xfs btrfs drbg ansi_cprng algif_skcipher af_alg dm_crypt raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq libcrc32c raid1 raid0 multipath linear rtsx_pci_sdmmc crct10dif_pclmul crc32_pclmul aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd i915_bpo intel_ips rtsx_pci i2c_algo_bit psmouse drm_kms_helper ahci syscopyarea libahci sysfillrect sysimgblt e1000e fb_sys_fops drm ptp pps_core wmi video fjes Jul 24 21:06:03 synlap01 kernel: [84597.934597] CPU: 2 PID: 21878 Comm: kworker/2:3 Tainted: P OE 4.4.0-31-generic #50-Ubuntu Jul 24 21:06:03 synlap01 kernel: [84597.934599] Hardware name: LENOVO 20FAS05Q00/20FAS05Q00, BIOS N1CET37W (1.05 ) 01/15/2016 Jul 24 21:06:03 synlap01 kernel: [84597.934610] Workqueue: events drm_dp_destroy_connector_work [drm_kms_helper] Jul 24 21:06:03 synlap01 kernel: [84597.934612] 0286 4e977f58 880291d63cd8 813f1143 Jul 24 21:06:03 synlap01 kernel: [84597.934616] 880291d63d20 c0282738 880291d63d10 81081102 Jul 24 21:06:03 synlap01 kernel: [84597.934619] 880424a02800 880503d77800 8800b413aa58 8800b413a658 Jul 24 21:06:03 synlap01 kernel: [84597.934622] Call Trace: Jul 24 21:06:03 synlap01 kernel: [84597.934629] [] dump_stack+0x63/0x90 Jul 24 21:06:03 synlap01 kernel: [84597.934634] [] warn_slowpath_common+0x82/0xc0 Jul 24 21:06:03 synlap01 kernel: [84597.934637] [] warn_slowpath_fmt+0x5c/0x80 Jul 24 21:06:03 synlap01 kernel: [84597.934647] [] ? drm_atomic_helper_set_config+0x92/0xb0 [drm_kms_helper] Jul 24 21:06:03 synlap01 kernel: [84597.934669] [] ? drm_atomic_state_free+0x4e/0x70 [drm] Jul 24 21:06:03 synlap01 kernel: [84597.934702] [] intel_dp_destroy_mst_connector+0xec/0x100 [i915_bpo] Jul 24 21:06:03 synlap01 kernel: [84597.934712] [] drm_dp_destroy_connector_work+0xad/0x150 [drm_kms_helper] Jul 24 21:06:03 synlap01 kernel: [84597.934717] [] process_one_work+0x165/0x480 Jul 24 21:06:03 synlap01 kernel: [84597.934720] [] worker_thread+0x4b/0x4c0 Jul 24 21:06:03 synlap01 kernel: [84597.934724] [] ? process_one_work+0x480/0x480 Jul 24 21:06:03 synlap01 kernel: [84597.934727] [] kthread+0xd8/0xf0 Jul 24 21:06:03 synlap01 kernel: [84597.934729] [] ? kthread_create_on_node+0x1e0/0x1e0 Jul 24 21:06:03 synlap01 kernel: [84597.934734] [] ret_from_fork+0x3f/0x70 Jul 24 21:06:03 synlap01 kernel: [84597.934737] [] ? kthread_create_on_node+0x1e0/0x1e0 Jul 24 21:06:03 synlap01 kernel: [84597.934741] ---[ end trace b87d7a74c9a0e017 ]--- -- You received

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report.
