hi,

I am using dual monitor configuration on Ubuntu 19.10 with Unity desktop. Everything is working correctly in this configuration:



but when I change it to this configuration:



I am having huge screen tearing and the desktop shows randomly large chunks of multiple frames (several frames mixed in the frame buffer). The screen is stable, though, no flickering, etc. The issues appear on both monitors.

I already applied this solution: https://github.com/bauca/graphics-switcher

My hardware is i7-8700k iGPU and 2x 1080p60 monitor.

Do you think a dedicated graphics card can solve this problem?

Possibly.

Which DDX is your GPU using now? Have you tried the other? The two are named modesetting, and intel. If using intel, there is an anti-tearing option that could help if not already applied. Read about it on https://learnubuntumate.weebly.com/s...-graphics.html

If this is of no help, ask the Intel driver developers via their mailing list. https://lists.freedesktop.org/mailma...info/intel-gfx

I had to manually set TearFree to make it work. Also worth mentioning it doesn't happen on Gnome, only with Unity.

how does this work, is it broken?

I suppose if it doesn't work for you there might be some minimum number of posts required before it is allowed.

Glad TearFree worked for you.
