That error is not really something that could ever cause the system to freeze, as it simply means that we cannot find a dkms module (and therefore gpu-manager can't get information about it). It should be more of a debugging message than an actual error.
Something else is probably failing in the kernel. Can you attach your /var/log/gpu-manager.log , please? Also, please attach your /var/log/kern.0.log after reproducing the problem. ** Changed in: ubuntu-drivers-common (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1655348 Title: gpu-manager Error: can't open /lib/modules/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1655348/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
