Ubuntu 18.04 marked the transition to a new, more granular, packaging of the NVIDIA drivers, which, unfortunately, combined with a change in logind, and with the previous migration from Lightdm to Gdm3, caused (Intel+NVIDIA) hybrid laptops to stop working the way they used to in Ubuntu 16.xx and older.

The following are the main issues experienced by our users:

  • An increase in power consumption when using the power saving profile (i.e. when the discrete GPU is off).
  • The inability to switch between power profiles on log out (thus requiring a reboot).

We have backported a commit to solve the problem with logind, and I have worked on a few changes in gpu-manager, and in the other key components, to improve the experience when using Gdm3.

NOTE: fixes for Lightdm, and for SDDM still need some work, and will be made available in the next update.

Both issues should be fixed in Ubuntu 18.10, and I have backported my work to Ubuntu 18.04, which is now available for testing.

If you run Ubuntu 18.04, own a hybrid laptop with an Intel and an NVIDIA GPU (supported by the 390 NVIDIA driver),  we would love to get your feedback on the updates in Ubuntu 18.04.

If you are interested, head over to the bug report, follow the instructions at the end of the bug description, and let us know about your experience.

In this Ubuntu release cycle I worked, among other things, on improving user experience with hybrid systems and proprietary graphics drivers. The aim was to make it easier to enable the discrete card when in need of better performance i.e. when the integrated card wouldn’t be enough.

In 13.10 I focused mainly on enablement, making sure that by installing one extra package together with the driver, users would end up with a fully working system with no additional configuration required on their end.

As for 12.04.3, I backported my work from 13.10 and I also made sure that Jockey (the restricted drivers manager in Precise) detects systems with hybrid graphics, recommends the correct driver – hiding any drivers which may support the card but not in a hybrid graphics context – and installs the extra package when users decide to enable the discrete card. The installation process is very straightforward, however, if you’re still using the old kernel/X stack, Jockey won’t show any drivers. The backported stack from Raring (which comes by default with 12.04.3) is required.

There are some known issues, which will be fixed in a near future.

If you would like to try this work on your system, you can find the instructions here.

As you might already know, this release cycle we’re providing updated proprietary graphics drivers using the -updates flavours of our driver packages (e.g. nvidia-current-updates, fglrx-updates). These updates are optional and, if you don’t want to run the risk of dealing with regressions, you may want to keep using the non-updates flavours (e.g. nvidia-current, fglrx, etc.).

If you’d like to help us test the new drivers, we have 2 updates available:

Nvidia’s (nvidia-current-updates) 285.05.09 and AMD’s fglrx 11.11 release

Please leave your feedback in the bug reports so that the SRU team can promote the drivers (currently in the oneiric-proposed repository) to regular distro updates.

NOTE: you might also want to keep an eye on this twitter page for more updates.
