Description

I have a thinkpad P70 with debian testing and 4.11.6 kernel. A recent-ish upgrade broke something and now I'm getting loads of spam in my Xorg.log

[  5031.435] (WW) modeset(0): flip queue failed: Invalid argument
[  5031.435] (WW) modeset(0): Page flip failed: Invalid argument
[  5031.435] (EE) modeset(0): present flip failed
[  5031.519] (WW) modeset(0): flip queue failed: Invalid argument
[  5031.519] (WW) modeset(0): Page flip failed: Invalid argument
[  5031.519] (EE) modeset(0): present flip failed
(...)

by loads of spam I mean several hundred megabytes per day The X server hangs every few days and when it works, 3D performance seems poor

system info:
ii  libdrm-intel1:amd64        2.4.74-1
ii  xserver-xorg-core          2:1.19.2-1
ii  xserver-xorg-video-intel   2:2.99.917+git20161206-1

Debian seems to require the use of the modsetting driver: xserver-xorg-video-intel (2:2.13.0-2) unstable; urgency=low

• Starting from 2.10, the Intel X driver depends on a kernel driver for mode setting (that's called KMS). The corresponding kernel option is CONFIG_DRM_I915, and is enabled in Debian kernels.
• To enable KMS, either of those should be sufficient:
  • /etc/modprobe.d/i915-kms.conf should contain: options i915 modeset=1

kernel: 4.11.6-amd64-preempt
