[drm:intel_pipe_update_start [i915]] *ERROR* Potential atomic update failure on pipe A

Maybe the solution to get rid of the above dmesg log spamming could be mentioned? You just add `options i915 enable_psr=0` to the file `/etc/modprobe.d/i915.conf`. Bjourne (talk) 17:04, 19 August 2016 (UTC)

DRI3 confusion

I've seen in the forum people ask from time to time how to enable DRI3 on their system.

As stated many times there, DRI3 should be on for most (if not all) of them. But people keep telling them to check

cat /var/log/Xorg.0.log | grep DRI

which shows up this message:

GLX: Initialized DRI2 GL provider for screen 0

which is *not accurate*.

If you run this command instead:

LC_ALL=C LIBGL_DEBUG=verbose glxinfo | grep DRI

you might stump with this other message:

libGL: Using DRI3 for screen 0

which proves you are using DRI3 even though X11 doesn't reply with the correct information.

The command was adapted from xorg mailing list.

So, it think adding this information in the page could be of major interest. What do you think?

Guide for screen scaling with external displays via xrandr?

I tried to find instructions for scaling the display resolution without stretching on this wiki page, but the section only says that it's not implemented in the Intel drivers yet. However, this stackexchange thread has a workaround using an xrandr transform matrix. Should this be added to the wiki page?

Screen flickering

Intel's power saving features might lead to flickering on some devices visible in the desktop, login manager and even in the konsole. Add the kernel parameter intel_idle.max_cstate=1 and reboot.

Driver issues on 11th Gen CPU

I've just left a comment in Talk:Dell_XPS_13_(9310)#Video drivers about issues with modesetting drivers on the new XPS 13. The issue appears when using modesetting drivers and is resolved when installing the xf86-video-intel package, which seems to go against most of the advice in this Wiki and the internet at large. The issue is not simple to describe, so I will just copy-paste what I've written on the other page: "some weird jittery behaviour in the rendering of text. For example, when attempting to type '' in a browser address field the text rendering would suddenly jump back by 1/2 strokes (I'm typing 'ch', the 'c' appears shortly but the screen immediately refreshes to only show 'wiki.a') and refuse to update for maybe a second. It would then catch up if I kept typing." Is this a known issue with 11th Gen Intel CPUs? The model I have has an i7-1165G7, which includes the new Intel Iris Xe Graphics.
