@gianluca, If you are using the Linux kernel from Ubuntu 14.04, such as 3.13.0-{39,40,43}-generic, those DKMS packages should not affect your system. You can remove them by `sudo apt-get purge oem-audio-hda-daily-lts-quantal oem-wireless-bluetooth-intel-7260` if you think they are redundant. `uname -r` can check the kernel version.
BTW, `ubuntu-drivers devices` may also provide the helpful information. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315221 Title: 8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses connection/becomes unusable on Intel 7260 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
