<div> </div>
<div class="signature">I have recently updated my Lenovo T440p with a dual graphics card (Intel Core + GeForce GT 730M) to OpenSUSE Leap 15.1. Since then, the external screen (connected either via VGA, DVI, HDMI, or DisplayPort) has a vertically stretched output which jumps horizontally in high frequency. Whenever touching any settings for the built in display (e.g. by gnome-control-center), also this screen starts incorrect display. Sometimes, however, also the external screen works as expected.</div>

<div class="signature">Installed driver version is (only 2D installed):</div>
<div class="signature">xf86-video-nouveau: 1.0.15-lp151.4.1</div>
<div class="signature">libvdpau_nouveau: 18.3.2-lp151.22.4</div>
<div class="signature">libdrm_nouveau2: 2.4.97-lp151.1.1</div>
<div class="signature"> </div>
<div class="signature">I have followed your instructions on the TroubleShooting page, No signs for NVIDIA drivers running, everything appears to be okay. Minimal xorg.conf did not work, screenshots are okay.Unfortunately, I failed in installing the most recent nouveau version (neither /lib/modules/4.12.14-lp151.28.4-default/source nor /lib/modules/4.12.14-lp151.28.4-default/build are present on my computer even though I have installed the Kernel sources). The installed version is still quite new, isn't it?</div>
<div class="signature"> </div>
<div class="signature">I suspect that I might have the issue you describe under "Blank monitor, flicker, snow, or other random live image corruption". I would like to make sure, however. And since you warn with regards to potential permanent damage, I would like to make sure, first.</div>
<div class="signature">Can you confirm that it should be this issue? Or are there any other things I should try first?</div>
