<pre><span class="quote">> Reporter, please comment to question raised by DK.</span >
Sorry for the late response!
<span class="quote">> To be sure, the command line option you are using is "i915.enable_psr=1" right ? </span >
Correct, as you can see in dmesg boot option is "i915.enable_psr=1".
<span class="quote">> When do you start seeing the flip time outs? login screen? or are you running any tests?</span >
In my case there is no login screen, because autologin is enabled in Gnome
settings. I run test described in item 2:

<span class="quote">> What happens if you keep the screen busy? like playing a video or let's say keep moving the cursor?</span >
Can't tell for sure, because I wasn't able to use Wayland session long enough
due to issues with Gnome's integrated onscreen keyboard, and lack of other
Wayland-compatible onscreen keyboards. As far I remember issue does not happen,
but maybe because I didn't test long enough.</pre>
