Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- 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/1800550 Title: Xorg freeze Status in xorg-server package in Ubuntu: Incomplete Bug description: Both during and after installation (meaning while running the USB iso and booting from HDD after) ubuntu will rapidly become unresponsive and eventually hang when my 4k monitor is plugged in. I have 2 monitors, a 1920x1080, and a 4k. Everything works absolutely perfectly if I only use the 1920 monitor (this is where I am working from right now) but the moment the other monitor is plugged in I get problems. When I cold boot into the system from the small 1920x1080 monitor and then plug in the 4k monitor, the screen on my smaller monitor will glitch before returning to normal a few seconds later, while the 4k monitor never displays an image. The OS begins to bog down, the mouse begins to lag and become less responsive. If I open the display manager I can see that ubuntu has properly detected the 4k monitor and has the correct default settings (resolution, refresh rate, etc.) but attempting to make any changes will result in an immediate crash/hang upon pressing the "apply" button. If I cold boot ubuntu with only the 4k monitor plugged in, I see purple splash screen and ubuntu logo screens (at the correct resolutions) but the monitor output stops and I see only a black screen before the login screen is reached. If I cold boot with both monitors plugged in I see the splash screen and logo, there is a brief moment where the small monitor glitches, and then I see only the magenta backdrop of the login screen but there are no UI elements, and This is only seen on the small monitor; the 4k monitor has once again lost input and turned black.
