I have 16.04LTS 64bit Desktop installed on my Dell Precision M4400 laptop which does use NVidia graphics card. I have an Acer 4K monitor and am running the 340 series NVidia Linux 64 driver.
This morning the system installed an update, which included the series 4 kernel. The system boots and enters the X Windows login screen. After authenticating the password the system logs in and then immediately "logs itself back out" returning to the signon screen. This occurs for normal user and guest accounts. Any suggestions for a workaround? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1525735 Title: X server fails to start under regular user in Xenial Status in xorg-server package in Ubuntu: Confirmed Bug description: The newest ISO image of Ubuntu GNOME Xenial Xerus does not launch the graphical installer on boot. Instead, it waits at the text-based login screen. I can log in using the default username of 'ubuntu-gnome' and start the X server with 'sudo startx.' Note that just 'startx' does not work; the command must be run as root. I am able to proceed with the installation as normal after starting X. After the system is fully installed, the problem persists. X can still be started manually after login.
