<p>Is there another place to report this kind of issue? Didn't get
any feedback. Did I make mistakes in my mail? I already tried the
Ubuntu bug-tracker (see below) with no success.</p>
<p>Thank you,</p>

<p>My laptop (core m5-6y54) starts flickering after returning
from Suspend (to RAM) or other commands touching the video
driver (xrandr, powertop --calibrate, ...)</p>
<p>From kernel (tested with up to 5.7) I get the message:</p>

<p>but guys from Ubuntu seems not able to help (as it is an
upstream bug) !?<br>
</p>
<p>This happend not in older kernels, but these have the problem
not to go in power save states. So I think the fix of that </p>

<p>causes this regression. <br>
</p>
<p>Hope someone can help. For a laptop it is better to have
both - standby and power saving. Thank you.</p>
