I'm on 14.10 with: * Lenovo T440s (00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)) * 2 Dell U2413 displays with DP 1.2 enabled. * Kernel: 3.16.0-25-generic #33hf73386v20141106b1-Ubuntu SMP * Driver: ii xserver-xorg-video-intel 2:2.99.916+git20141112.f9f85b88-0ubuntu0sarvatt amd64 X.Org X server -- Intel i8xx, i9xx display driver
Both monitors shows up in unity-control-center's Display section, but when I attempt to enable either of them, the displays flash, and then I get "The selected configuration for displays could not be applied: could not set the configuration for CRTC 64". It looks like I get some sort of crash in the driver or kernel. I found this in the logs: [ 637.412] (II) intel(0): resizing framebuffer to 3840x2280 [ 637.449] (II) intel(0): switch to mode 1920x1200@60.0 on DP1-1 using pipe 1, position (1920, 0), rotation normal, reflection none ==> syslog <== Nov 19 11:56:14 dib kernel: [ 637.206389] ------------[ cut here ]------------ Nov 19 11:56:14 dib kernel: [ 637.206437] WARNING: CPU: 1 PID: 3415 at /build/buildd/linux-3.16.0/drivers/gpu/drm/i915/intel_ddi.c:850 intel_ddi_pll_select+0x7f/0x3c0 [i915]() Nov 19 11:56:14 dib kernel: [ 637.206439] Invalid DDI encoder type 11 Nov 19 11:56:14 dib kernel: [ 637.206441] Modules linked in: ctr ccm uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_core v4l2_common videodev media arc4 btusb intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm snd_hda_codec_realtek snd_hda_codec_generic snd_hda_codec_hdmi iwlmvm snd_hda_intel mac80211 rtsx_pci_ms memstick snd_hda_controller snd_hda_codec snd_hwdep joydev snd_pcm serio_raw snd_seq_midi snd_seq_midi_event iwlwifi snd_rawmidi cfg80211 lpc_ich rfcomm snd_seq bnep snd_seq_device bluetooth snd_timer 6lowpan_iphc thinkpad_acpi nvram snd shpchp intel_smartconnect mac_hid mei_me mei soundcore parport_pc ppdev binfmt_misc lp parport dm_crypt rtsx_pci_sdmmc crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd i915 psmouse ahci libahci rtsx_pci i2c_algo_bit drm_kms_helper e1000e drm ptp pps_core wmi video Nov 19 11:56:14 dib kernel: [ 637.206520] CPU: 1 PID: 3415 Comm: Xorg Tainted: G W 3.16.0-25-generic #33hf73386v20141106b1-Ubuntu Nov 19 11:56:14 dib kernel: [ 637.206522] Hardware name: LENOVO 20AQ005YUS/20AQ005YUS, BIOS GJET75WW (2.25 ) 03/28/2014 Nov 19 11:56:14 dib kernel: [ 637.206525] 0000000000000009 ffff8800c868baf0 ffffffff8178015c ffff8800c868bb38 Nov 19 11:56:14 dib kernel: [ 637.206529] ffff8800c868bb28 ffffffff8106fd7d ffff88020ee24000 000000000000000b Nov 19 11:56:14 dib kernel: [ 637.206533] ffff88020e810000 0000000000083d60 ffff8800c8fae400 ffff8800c868bb88 Nov 19 11:56:14 dib kernel: [ 637.206537] Call Trace: Nov 19 11:56:14 dib kernel: [ 637.206547] [<ffffffff8178015c>] dump_stack+0x45/0x56 Nov 19 11:56:14 dib kernel: [ 637.206554] [<ffffffff8106fd7d>] warn_slowpath_common+0x7d/0xa0 Nov 19 11:56:14 dib kernel: [ 637.206558] [<ffffffff8106fdec>] warn_slowpath_fmt+0x4c/0x50 Nov 19 11:56:14 dib kernel: [ 637.206588] [<ffffffffc029bc4f>] intel_ddi_pll_select+0x7f/0x3c0 [i915] Nov 19 11:56:14 dib kernel: [ 637.206614] [<ffffffffc0277d62>] haswell_crtc_mode_set+0x12/0x40 [i915] Nov 19 11:56:14 dib kernel: [ 637.206641] [<ffffffffc0287176>] __intel_set_mode+0x6d6/0xab0 [i915] Nov 19 11:56:14 dib kernel: [ 637.206667] [<ffffffffc028a456>] intel_set_mode+0x16/0x30 [i915] Nov 19 11:56:14 dib kernel: [ 637.206692] [<ffffffffc028b56a>] intel_crtc_set_config+0xa9a/0xe30 [i915] Nov 19 11:56:14 dib kernel: [ 637.206713] [<ffffffffc0143571>] drm_mode_set_config_internal+0x61/0xe0 [drm] Nov 19 11:56:14 dib kernel: [ 637.206733] [<ffffffffc0147503>] drm_mode_setcrtc+0x283/0x580 [drm] Nov 19 11:56:14 dib kernel: [ 637.206747] [<ffffffffc0137a4f>] drm_ioctl+0x1df/0x680 [drm] Nov 19 11:56:14 dib kernel: [ 637.206755] [<ffffffff811f4c28>] do_vfs_ioctl+0x2c8/0x4a0 Nov 19 11:56:14 dib kernel: [ 637.206759] [<ffffffff811e3201>] ? __sb_end_write+0x31/0x60 Nov 19 11:56:14 dib kernel: [ 637.206765] [<ffffffff811e0d72>] ? vfs_write+0x1b2/0x1f0 Nov 19 11:56:14 dib kernel: [ 637.206769] [<ffffffff811f4e81>] SyS_ioctl+0x81/0xa0 Nov 19 11:56:14 dib kernel: [ 637.206775] [<ffffffff817881ad>] system_call_fastpath+0x1a/0x1f Nov 19 11:56:14 dib kernel: [ 637.206777] ---[ end trace 4fa62fb37568112e ]--- Nov 19 11:56:14 dib kernel: [ 637.208375] ------------[ cut here ]------------ Nov 19 11:56:14 dib kernel: [ 637.208414] WARNING: CPU: 0 PID: 3415 at /build/buildd/linux-3.16.0/drivers/gpu/drm/i915/intel_ddi.c:850 intel_ddi_pll_select+0x7f/0x3c0 [i915]() Nov 19 11:56:14 dib kernel: [ 637.208417] Invalid DDI encoder type 11 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1104230 Title: DisplayPort 1.2 MST support is missing in the Intel driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1104230/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
