After having the same issue I have done a clean new install. The new kernel version is 4.12.14, as you suspected. In OpenSUSE, I suspect it was version 3.16.7. Unfortunately, I cannot find out anymore which nouveau version I have used before. I have a file backup of the old installation. Can I find out which nouveau version I had before?</div> <div> </div> <div>During all my attempts, I have also installed Ubuntu 18.04.2 with the same strange behaviour. I guess this was the 4.18 kernel version?</div> <div>Do you know which distrubtion already uses a 5.0 kernel? I will try a live system, then.</div> <div> </div> <div>I have a docking station with 4 monitor ports: VGA, DVI, HDMI, Displayport. And my laptop has VGA and Mini-Displayport. My monitor (Fujitsu P24W-7 LED) has VGA, DVI, HDMI, and Displayport.</div> <div>I have tried DVI->DVI and DisplayPort->HDMI cable on the docking station (I don't hav. In one of my attempts, I have connected the screen via analog VGA cable directly to the computer. The same effect resulted. Thus, I believe the docking station and digital connection to the monitor are not part of the problem.</div> <div> </div> <div>Best regards</div> <div>Harald</div> <div> </div> <div>PS: I guess sending to the mailing list and omitting your personal mail address is correct, right?</div> <div> <div> <div> <div style="margin: 10.0px 5.0px 5.0px 10.0px;padding: 10.0px 0 10.0px 10.0px;border-left: 2.0px solid rgb(195,217,229);"> <div style="margin: 0 0 10.0px 0;"><b>Gesendet:</b> Dienstag, 18.

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.<br/> ><br/> > Installed driver version is (only 2D installed):<br/> > xf86-video-nouveau: 1.0.15-lp151.4.1<br/> > libvdpau_nouveau: 18.3.2-lp151.22.4<br/> > libdrm_nouveau2: 2.4.97-lp151.1.1<br/> ><br/> > I have followed your instructions on the TroubleShooting page, No signs for NVIDIA drivers running, everything appears to be okay.
