I can see bug 1861609 happening in XorgLogOld.txt, but also you seem to have a few vbox-related kernel crashes. Overall I think this is bug 1861609 which seems to be common on VirtualBox. The matter of two instances of startup programs is a separate issue, perhaps a lightdm bug. ** This bug has been marked a duplicate of bug 1861609 Xorg crashed with assertion failure (usually in a VM) at [privates.h:121/122: dixGetPrivateAddr: Assertion `key->initialized' failed] and call stack comes from DRIMoveBuffersHelper -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2040037 Title: Xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2040037/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
