Works fine, however the only problem exists: after I close laptop cover or after some time of inactivity Ubuntu suspends or hibernate (do not know). After I resume it, it starts to work but in 10-15 sec Ubuntu freezes and I forced to power-off. Tried many things mentioned here: - blacklist nouveau - install older kernel - 4.14.41 - update to newer - 4.18 or latest 5.3 kernel - switch to proprietary nvidia driver (was installed by default) - install `lightdm` instead of `gdm3` - dell software had run some recent firmware upgrade - etc Nothing work - it still freezes and it is impossible to work. The only suggestion I did not tried yet: install kubuntu and then original nvidia driver from manufacturer site. Do not know however if it affects warranty? ;) Any ideas how to solve, how to diagnose? Thanks!
