No, not needed on earlier than xenial (utopic worked fine) - someone should probably look at the oops though that backtrace that I still see in the logs - but it's only a low, since everything apparently works.
-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1525509 Title: regression on 4.3.x: i945/Display corruption (before X, X never starts)) Status in linux package in Ubuntu: Incomplete Bug description: This laptop works with 4.2.0-19 and fails with 4.3.0-2. At boot (before X) the display is corrupt - with the entire screen shifted halfway across the screen with the kernel boot text mostly readable, just shifted over (and some crud at the top). X doesn't start. Returning to 4.2.0-19 (as now) and it's fine. In the 4.3.0-2 world I see the following warning in the dmesg: [ 14.118080] WARNING: CPU: 1 PID: 14 at /build/linux-Os09TY/linux-4.3.0/drivers/gpu/drm/drm_atomic.c:491 drm_atomic_check_only+0x46e/0x540 [drm]() [ 14.119902] Modules linked in: parport_pc ppdev lp parport autofs4 i915 i2c_algo_bit drm_kms_helper syscopyarea firewire_ohci sysfillrect sysimgblt fb_sys_fops psmouse firewire_core sdhci_pci e100 pata_acpi mii sdhci crc_itu_t drm fjes video [ 14.123614] CPU: 1 PID: 14 Comm: kworker/1:0 Tainted: G W 4.3.0-2-generic #11-Ubuntu [ 14.125467] Hardware name: TOSHIBA Equium A100/MPAD-MSAE Customer Reference Boards, BIOS 2.10 10/23/2006 [ 14.127339] Workqueue: events output_poll_execute [drm_kms_helper] [ 14.129181] 0000000000000000 00000000fe15c8fd ffff8800bb01ba38 ffffffff813d23a4 [ 14.131009] 0000000000000000 ffff8800bb01ba70 ffffffff8107d082 ffff88003590a000 [ 14.132820] ffff8800b4d61400 0000000000000001 0000000000000000 ffff8800ba182e00 [ 14.134621] Call Trace: [ 14.136413] [<ffffffff813d23a4>] dump_stack+0x44/0x60 [ 14.138207] [<ffffffff8107d082>] warn_slowpath_common+0x82/0xc0 [ 14.139990] [<ffffffff8107d1ca>] warn_slowpath_null+0x1a/0x20 [ 14.141782] [<ffffffffc004ab9e>] drm_atomic_check_only+0x46e/0x540 [drm] [ 14.143569] [<ffffffffc004ad5d>] ? drm_atomic_set_fb_for_plane+0x2d/0x90 [drm] [ 14.145374] [<ffffffffc004ac87>] drm_atomic_commit+0x17/0x60 [drm] [ 14.147211] [<ffffffffc01b3ba5>] intel_get_load_detect_pipe+0x3d5/0x530 [i915] [ 14.149029] [<ffffffffc01eac8d>] intel_tv_detect+0x13d/0x5f0 [i915] [ 14.150801] [<ffffffffc004546e>] ? drm_get_edid+0x3e/0x3f0 [drm] [ 14.152543] [<ffffffff817f9d36>] ? schedule_hrtimeout_range_clock.part.23+0xa6/0x150 [ 14.154271] [<ffffffffc011dd05>] drm_helper_probe_single_connector_modes_merge_bits+0x235/0x4d0 [drm_kms_helper] [ 14.156025] [<ffffffffc011dfb3>] drm_helper_probe_single_connector_modes+0x13/0x20 [drm_kms_helper] [ 14.157757] [<ffffffffc01297fc>] drm_fb_helper_hotplug_event+0x8c/0x120 [drm_kms_helper] [ 14.159513] [<ffffffffc01c39fe>] intel_fbdev_output_poll_changed+0x1e/0x30 [i915] [ 14.161261] [<ffffffffc011d657>] drm_kms_helper_hotplug_event+0x27/0x30 [drm_kms_helper] [ 14.163031] [<ffffffffc011d857>] output_poll_execute+0x197/0x1e0 [drm_kms_helper] [ 14.164808] [<ffffffff810961aa>] process_one_work+0x1aa/0x440 [ 14.166567] [<ffffffff8109648b>] worker_thread+0x4b/0x4c0 [ 14.168326] [<ffffffff81096440>] ? process_one_work+0x440/0x440 [ 14.170068] [<ffffffff8109c6e8>] kthread+0xd8/0xf0 [ 14.171821] [<ffffffff8109c610>] ? kthread_create_on_node+0x1e0/0x1e0 [ 14.173577] [<ffffffff817fae8f>] ret_from_fork+0x3f/0x70 [ 14.175317] [<ffffffff8109c610>] ? kthread_create_on_node+0x1e0/0x1e0 [ 14.177081] ---[ end trace cdd47054bd68533c ]--- This is running an up to date Xenial.
