Title:
Ubuntu freezes after resume from suspend/hibernate in 10-15 sec
Status in linux package in Ubuntu:
Incomplete
Bug description:
Asked her as well: https://askubuntu.com/questions/1247968/ubuntu-
freezes-after-resume-from-suspend-hibernate-in-10-15-sec
Bought new laptop - [Dell
Latitude-5501][https://www.dell.com/ru/business/p/latitude-15-5501-laptop/pd]
with Ubuntu 18.04.4. 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!
