Forgot to mention: the "Additional drivers" does not list any nvidia driver at all, mirroring what lspci does (no listing either). The ubuntu 16.04 system as a whole ignores the nvidia card of this macbook pro 11,1 laptop.

An nvidia card, which was both recognized in Ubuntu 14.04 with kernels 3.13.*, and worked well using the provided drivers under "Additional drivers". 2. An intel integrated card, which was not in use under Ubuntu 14.04, but which now, under ubuntu 16.04, is the only card in use. The 'lspci' command states: 00:02.0 VGA compatible controller [0300]: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a2e] (rev 09) ... and there is no trace at all of the nvidia card under lspci. dmesg shows one crytic message, perhaps indicating that the nvidia card could not be recognized: [ 0.190838] pci 0000:00:02.0: Video device with shadowed ROM dmesg lists a number of "failed" entries, such as: [ 11.791463] usb 1-3: hub failed to enable device, error -62 [ 24.891009] wl: module verification failed: signature and/or required key missing - tainting kernel ... and also: [ 0.190096] pci 0000:06:00.0: BAR 15: no space for [mem size 0x00200000 64bit pref] [ 0.190098] pci 0000:06:00.0: BAR 15: failed to assign [mem size 0x00200000 64bit pref] [ 0.190099] pci 0000:06:04.0: BAR 14: no space for [mem size 0x00200000] [ 0.190100] pci 0000:06:04.0: BAR 14: failed to assign [mem size 0x00200000] [ 0.190102] pci 0000:06:04.0: BAR 15: no space for [mem size 0x00200000 64bit pref] [ 0.190103] pci 0000:06:04.0: BAR 15: failed to assign [mem size 0x00200000 64bit pref] [ 0.190104] pci 0000:06:06.0: BAR 14: no space for [mem size 0x00200000] [ 0.190105] pci 0000:06:06.0: BAR 14: failed to assign [mem size 0x00200000] [ 0.190107] pci 0000:06:06.0: BAR 15: no space for [mem size 0x00200000 64bit pref] [ 0.190108] pci 0000:06:06.0: BAR 15: failed to assign [mem size 0x00200000 64bit pref] [ 0.190109] pci 0000:06:00.0: BAR 13: no space for [io size 0x1000] [ 0.190110] pci 0000:06:00.0: BAR 13: failed to assign [io size 0x1000] [ 0.190111] pci 0000:06:04.0: BAR 13: no space for [io size 0x1000] [ 0.190112] pci 0000:06:04.0: BAR 13: failed to assign [io size 0x1000] [ 0.190113] pci 0000:06:06.0: BAR 13: no space for [io size 0x1000] [ 0.190114] pci 0000:06:06.0: BAR 13: failed to assign [io size 0x1000] [ 0.190116] pci 0000:06:06.0: BAR 14: no space for [mem size 0x00200000] [ 0.190117] pci 0000:06:06.0: BAR 14: failed to assign [mem size 0x00200000] [ 0.190119] pci 0000:06:06.0: BAR 15: no space for [mem size 0x00200000 64bit pref] [ 0.190120] pci 0000:06:06.0: BAR 15: failed to assign [mem size 0x00200000 64bit pref] [ 0.190121] pci 0000:06:06.0: BAR 13: no space for [io size 0x1000] [ 0.190122] pci 0000:06:06.0: BAR 13: failed to assign [io size 0x1000] [ 0.190124] pci 0000:06:04.0: BAR 14: no space for [mem size 0x00200000] [ 0.190125] pci 0000:06:04.0: BAR 14: failed to assign [mem size 0x00200000] [ 0.190126] pci 0000:06:04.0: BAR 15: no space for [mem size 0x00200000 64bit pref] [ 0.190127] pci 0000:06:04.0: BAR 15: failed to assign [mem size 0x00200000 64bit pref] [ 0.190129] pci 0000:06:04.0: BAR 13: no space for [io size 0x1000] [ 0.190130] pci 0000:06:04.0: BAR 13: failed to assign [io size 0x1000] [ 0.190131] pci 0000:06:00.0: BAR 15: no space for [mem size 0x00200000 64bit pref] [ 0.190132] pci 0000:06:00.0: BAR 15: failed to assign [mem size 0x00200000 64bit pref] [ 0.190133] pci 0000:06:00.0: BAR 13: no space for [io size 0x1000] [ 0.190134] pci 0000:06:00.0: BAR 13: failed to assign [io size 0x1000] Please let me know what further information I could provide to facilitate addressing these issues.
