Mario Costa: 1) Please provide the output of the following terminal command (not manually attach anything found): ls -la /var/crash
2) As per your Bug Description, you are using the non-default kernel parameter: radeon.runpm=0 Could you please advise to if this is required to use? Also, if you remove it, does the crash still happen? 3) As per the sticker of the monitor itself (not from the Bug Description, or the result of a terminal command), could you please provide the full monitor manufacturer and model? 4) How are you connecting the monitor to the computer, via DisplayPort- to-DisplayPort cable, DisplayPort-to-HDMI cable, dongle/adapter, etc.? 5) If you keep the external monitor disconnected from the computer on boot up, and after login then plug it in does this provide a WORKAROUND? 6) Does the crash only happen after coming up from a cold boot, only after resuming from suspend, etc.? ** Changed in: xorg (Ubuntu) Importance: Low => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1771539 Title: Xorg crash Status in xorg package in Ubuntu: Incomplete Bug description: When I try to use ubuntu with dual desktop display it crashes continuously, and entering into login mode. I cannot use dual display. To use an external monitor, I have to start the laptop with the computer closed. It seems to be related to the graphic card, maybe dual graphic card of the laptop.
