ethany, I do not really remember. Try 13.04 (and 12.04 if it is still in 13.04). It was one of those, IIRC, that did not have it. Problem is that so much has changed in the kernel since then. I went through a huge kernel bisect project to then be told to report it to the kernel i915 group and got no interest. I am over it, now. I am convinced that the i915 driver will never be fixed for our particular hardware as it is so old. <rant> Nobody really cares. Typical 80/20. Get it 80% of the way there then loose interest in doing the rest of the 80% required to get it 'right'. Typical of all open source projects. </rant>
As for the last time I tried 15.10, on all of my machines (3 different hardware, processors, etc), the system just randomly suspends. Without warning and nothing weird shows up in the log. Just browsing in firefox or running an app and then bam instant suspend. It all comes back when powered on, but not really usable. I just updated and am trying again on one machine and see if it is fixed. No bug reports relate to this bug, either. It just did it again. Suspended without warning while I was typing this. The latest kernel update for 15.10 4.2.0-23-generic shows this: ------------[ cut here ]------------ [ 163.795945] WARNING: CPU: 1 PID: 1162 at /build/linux-AFqQDb/linux-4.2.0/drivers/gpu/drm/i915/intel_display.c:12256 intel_modeset_check_state+0x3ab/0x6d0 [i915]() [ 163.795947] encoder's hw state doesn't match sw tracking (expected 0, found 1) [ 163.795948] Modules linked in: rpcsec_gss_krb5 auth_rpcgss nfsv4 nfs lockd grace fscache binfmt_misc arc4 uvcvideo b43 videobuf2_vmalloc videobuf2_memops videobuf2_core v4l2_common snd_hda_codec_idt videodev snd_hda_codec_generic bcma snd_hda_codec_hdmi media dell_wmi mac80211 sparse_keymap snd_hda_intel r852 gpio_ich dell_laptop sm_common snd_hda_codec nand snd_hda_core nand_ecc snd_hwdep snd_pcm nand_bch dcdbas snd_seq_midi bch snd_seq_midi_event snd_rawmidi nand_ids cfg80211 dell_smm_hwmon mtd snd_seq snd_seq_device ssb_hcd input_leds r592 joydev snd_timer serio_raw memstick snd lpc_ich soundcore shpchp mac_hid coretemp sunrpc parport_pc ppdev lp parport autofs4 hid_generic usbhid hid psmouse i915 ahci libahci sdhci_pci firewire_ohci sdhci pata_acpi ssb firewire_core crc_itu_t sky2 i2c_algo_bit [ 163.796030] wmi drm_kms_helper drm video [ 163.796036] CPU: 1 PID: 1162 Comm: Xorg Tainted: G W 4.2.0-23-generic #28-Ubuntu [ 163.796044] Hardware name: Dell Inc.
