I managed to remove "libcuda" and every package that was depending on ...snapd...mount by modifying "/var/lib/dpkg/info/[the package].prerm" and putting "exit 0" right after the shebang. I removed nvidia, tried reinstalling different versions and configuring in different ways 4 times... and it didn't work(can login but no window frame). Tried to install nouveau instead and still no window frame. Tried reinstalling ubuntu-desktop, unity, compiz... still no luck. unity/compiz --replace. -- no luck.
I will try to uninstall nouveau and attempt Matteo's solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589006 Title: Failed unmounting Mount unit for nvidia support in snappy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1589006/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
