Tried booting the system with linux-image-4.4.0-154-generic. X works on this kernel. Tried booting the system with linux-image-4.15.0-47-generic. X works on this kernel.
Presumably there is some bad interaction between the nvidia module and 4.15.0-55-generic. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1838192 Title: X server segfaults immediately at startup Status in xorg package in Ubuntu: New Bug description: This system was working perfectly 3 months ago. I turned it off and left it off until yesterday. When I came back to it and turned it on, it worked initially but then the nvidia video card (nvidia GeForce GT 630) decided to die. I replaced the video card with an nvidia GeForce GT 710 and hit this issue. The machine also has integrated Intel graphics which I am not using. The system boots fine, I see BIOS boot messages and linux kernel messages until X tries to start. After it does that, nothing is displayed on screen. If I try to switch to another VT with <c><a><F2> for example, I get no output then either.

I am using the nvidia drivers and they seem not to be loading for some reason. I need to use them for vdpau support.
