Can confirm now that simply unplugging the USB powered hub and rebooting fixes the Nautilus 1 pixel font problem. Another problem where the built-in display was black and only the TV got wallpaper was also fixed. Plugging the USB hub in after boot did not break Nautilus fonts.
On the hub are: 1) UPS battery status monitor 2) Smartphone 3) Blue tooth ear buds 4) Laser Printer 5) Couple of spare cables -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1506704 Title: Thin font, nautilus doesn't integrate with Unity. Status in gnome-settings-daemon package in Ubuntu: Confirmed Bug description: It happens frequently (around 1/2 of the time) that when I boot the computer, font lines are only one pixel thick. This concerns watch in the sys-tray, all item in the menu of all applications, as well as all fonts in Nautilus. When this happens. Nautilus doesn't display menu in the Unity menu bar, but displays an additional button showing three horizontal lines for bringing up the menu. This problem has been with me for years, although sometimes disappears for months at a time when I run sudo apt-get update. This time it re- emerged after upgrading to 15.10 beta (Wily). It happens usually on power-up, and disappears after system restart. (To appear again on the next power-up).
