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. ** Summary changed: - XOrg crashes/bugs on Dual GPU 20.04 / 21.04 + Crashes/bugs on Dual GPU 20.04 / 21.04 ** Package changed: xorg (Ubuntu) => xfce4-session (Ubuntu) ** Also affects: marco (Ubuntu) Importance: Undecided Status: New ** Summary changed: - Crashes/bugs on Dual GPU 20.04 / 21.04 + Crashes/bugs with dual GPUs when using Nvidia-470 -- 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/1942314 Title: Crashes/bugs with dual GPUs when using Nvidia-470 Status in marco package in Ubuntu: New Status in xfce4-session package in Ubuntu: New Bug description: Install 20.04 or 21.04, install the proprietary drivers.
