I just updated my Ubuntu Desktop from 19.04 to 19.10. Then I found gnome setting won't launch for me. The problem is the same as described in this post. GNOME Settings Won't Launch in Ubuntu 19.04
Command outputs are:
$ gnome-control-center --verbose Failed to register: Timeout was reached
$ journalctl -b |grep gnome-control-center .... gnome-control-center.desktop: nvc0_screen_create:1107 - Error allocating PGRAPH context for M2MF: -16 ... gnome-control-center.desktop: Failed to register: Timeout was reached
$ uname -a 5.3.0-18-generic #19-Ubuntu SMP Tue Oct 8 20:14:06 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
$ gnome-control-center --version gnome-control-center 3.34.1
I have reinstalled the package as suggested by google search, but it refuses to work. Any help is appreciated.
