Description Peter Eszlari 2017-12-15 01:31:00 UTC
Live system like this one from SUSE ("Krypton") do not include the nouveau mesa driver, because the driver can be unstable. They fall back to llvmpipe, which is in combination with a UHD screen unusable slow. I think in this case, composting should be disabled automatically.

Distro issue.
Comment 2 Peter Eszlari 2017-12-15 23:26:36 UTC
How is it a distro issue, when there's no stable driver?

Other distros include the driver.
