dmesg
Hi there,
as discussed with mupuf on #intel-gfx yesterday I am getting an ugly mouse
pointer flickering after installing Linux (KDE/Plasma 5.9) on my new ThinkPad
T470p (Kaby Lake, HD Graphics 630, Nvidia graphics disabled via ACPI,
modesetting). I have three monitors attached (one built-in HiDPI screen, two
external ones). I have been able to track down the screen flicker to using
--scale 0.75x0.75 on eDP-1 (the internal screen) via xrandr (I need to apply
some screen-specific scaling due to the two external screens being normal DPI
and the internal one being HiDPI).
I am using Arch Linux and hit the issue on both the regular Kernel 4.11.2 and
the LTS Kernel 4.9.30.
$ uname -a
Linux vega 4.11.2-1-ARCH #1 SMP PREEMPT Mon May 22 06:53:49 CEST 2017 x86_64
GNU/Linux
Linux distribution: Arch Linux (x86_64)
Machine or mother board model: Lenovo ThinkPad T470p (i7-7820HQ)
Display connector: 1x eDP (2560x1440 internal 14" screen) 2x DP (2560x1440
external 25" screens connected via Lenovo Ultra Dock)
Video recording of flicker: <a href="https://goo.gl/photos/E1aspC36Zs967sUV6">https://goo.gl/photos/E1aspC36Zs967sUV6</a>
dmesg output and Xorg log attached.
xrandr command line:
-- 8< --
/usr/bin/xrandr -d :0.0 --output DP-3-2 --mode 2560x1440 --pos 0x0 --rotate
normal --primary --output DP-3-1 --mode 2560x1440 --pos 2560x0 --rotate normal
--output eDP-1 --mode 2560x1440 --pos 5120x774 --rotate normal --scale
0.75x0.75
-- 8< --
Please let me know if you need any further details.
Thanks,
Thilo</pre>
