Just upgraded to 15.04. I still get the error and sometimes it will not shut down and takes a long time to reboot.
Is this just that the i915 driver is not very good or that my hardware is not well supported? # lspci ... 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) (rev 0c) ... # dmesg | tail -28 [ 50.714016] ------------[ cut here ]------------ [ 50.714036] WARNING: CPU: 1 PID: 967 at /build/buildd/linux-3.19.0/drivers/gpu/drm/i915/intel_display.c:10801 intel_modeset_check_state+0x3c8/0x6a0 [i915]() [ 50.714037] encoder's hw state doesn't match sw tracking (expected 0, found 1) [ 50.714069] Modules linked in: rpcsec_gss_krb5 auth_rpcgss nfsv4 nfs lockd grace fscache ctr ccm binfmt_misc arc4 uvcvideo b43 snd_hda_codec_idt videobuf2_vmalloc snd_hda_codec_hdmi videobuf2_memops snd_hda_codec_generic videobuf2_core i915 snd_hda_intel v4l2_common snd_hda_controller bcma videodev snd_hda_codec dell_wmi mac80211 media snd_hwdep sparse_keymap gpio_ich snd_pcm snd_seq_midi snd_seq_midi_event snd_rawmidi r852 dell_laptop sm_common dcdbas cfg80211 nand nand_ecc i8k nand_bch snd_seq bch coretemp r592 nand_ids mtd snd_seq_device drm_kms_helper memstick snd_timer joydev drm ssb_hcd snd serio_raw soundcore i2c_algo_bit lpc_ich shpchp wmi mac_hid video sunrpc parport_pc ppdev lp parport autofs4 hid_generic usbhid hid ahci psmouse libahci firewire_ohci pata_acpi sdhci_pci firewire_core sdhci [ 50.714071] crc_itu_t ssb sky2 [ 50.714073] CPU: 1 PID: 967 Comm: Xorg Tainted: G W 3.19.0-15-generic #15-Ubuntu [ 50.714074] Hardware name: Dell Inc.
