Bug Description

I am trying to use the nouveau drivers on a recent (today) install of 18.04 on a 2.5yo laptop. Unfortunately the nvidia drivers don't work at all.

What I am finding is that the sluggishness of the display is comparable to the case when nouveau drivers are disabled. The only real difference is in the amount of noise coming from the fan because of a slightly reduced CPU load due to Xorg.

I don't even know where to start looking into this intelligently, but I would have expected that the drivers would have gotten to a usable state in the past 2 1/2 years since I last tried them on this machine.

Removing the nomodeset kernel parameter makes GDM snappier, but it then hangs on login (relevant portion of syslog attached).

Your kernel log in comment #2 is showing a lot of crashes in the nouveau kernel driver. The best and only remedies for that are:

(a) Install a newer kernel or just install a newer version of Ubuntu. Ubuntu 19.04: http://releases.ubuntu.com/19.04/ or kernel packages: https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

or

(b) Continue trying to get the Nvidia proprietary driver working, per bug 1830000.

Please undo the incomplete. The action that was asked for was performed in the comment #2.

Daniel van Vugt (vanvugt) wrote :

I think it's appropriate to stay Incomplete because this is essentially just a kernel bug, in the nouveau driver.

Option (b) above isn't directly relevant, but might be a workaround, even permanently. Any proper solution to this bug requires testing of option (a) in comment #4. So still incomplete.

The reason I ask this is that launchpad has an unfortunate approach to issue management (these two that you have been communicating in are a welcome change - thanks) where bugs go stale for years or are dropped due to lack of engagement from maintainers.

Daniel van Vugt (vanvugt) wrote :

Yes I am aware of the stale bug problem and have been on both ends.

But as the number of open bugs decreases (at least in some components), the problem should happen less:
