I got this problem too after upgrading to 18.04 on 09/19/2018. Whenever system settings is launched, the default first tab is wireless settings and it froze.
Meanwhile, syslog had print out below: Sep 19 14:16:00 localhost gnome-shell[1901]: message repeated 11 times: [ driver/gl/cogl-framebuffer-gl.c:1186: GL error (1286): Invalid framebuffer operation] Sep 19 14:16:11 localhost gnome-shell[2771]: JS ERROR: Exception in callback for signal: set-cursor-location: TypeError: this._currentWindow is null#012_setCurrentRect@resource:///org/gnome/shell/ui/keyboard.js:536:13#012wrapper@resource:///org/gnome/gjs/modules/_legacy.js:82:22#012_init/<@resource:///org/gnome/shell/ui/keyboard.js:512:13#012_emit@resource:///org/gnome/gjs/modules/signals.js:128:27#012_initPanelService/<@resource:///org/gnome/shell/misc/ibusManager.js:120:17 Sep 19 14:16:11 localhost /usr/lib/gdm3/gdm-x-session[2623]: (II) NVIDIA(GPU-0): Display (Lenovo Group Limited (DFP-0)) does not support NVIDIA Sep 19 14:16:11 localhost /usr/lib/gdm3/gdm-x-session[2623]: (II) NVIDIA(GPU-0): 3D Vision stereo.
