| howarth | Is anyone having any luck with installing the non-free nvidia drivers on Cosmic with a GTX 680? | 12:06 |
|---|---|---|
| howarth | Closest I have gotten is getting the stock nvidia-driver-390 to install but it still produces a black screen instead of the gdm | 12:06 |
| howarth | No obvious errors in the system log or X11.org.log | 12:07 |
| howarth | but I did notice that, unlike the System76 xenial nvidia installation, cosmis is loading both the nvidia and nouveau drivers | 12:08 |
| howarth | unless I am confused, cosmic uses nouveau for gdm but nvidia for the actual X11 session | 12:09 |
| howarth | which seems like it is just asking for trouble | 12:09 |
| gpunk | you need to uninstall nouveau/blacklist it | 12:31 |
| gpunk | buht it should be done by the nvidia installation | 12:32 |
| howarth | if you have the nvidia drivers installed successfully, do you have any blacklisting added by the the packages? | 13:21 |
| howarth | The System76 driver packages for xenial (they roll their own) use | 13:21 |
| howarth | blacklist nouveau | 13:22 |
| howarth | blacklist lbm-nouveau | 13:22 |
| howarth | blacklist nvidia-current | 13:22 |
| howarth | blacklist nvidia-173 | 13:22 |
| howarth | blacklist nvidia-96 | 13:22 |
| howarth | blacklist nvidia-current-updates | 13:22 |
| howarth | options nvidia_384_drm modeset=0 | 13:23 |
| howarth | is used in modprobes.d on System76 but the current nvidia packages seem to install a nouveau drm instead | 13:24 |
| howarth | I was also puzzled by the fact that the current nvidia packaging installed for 390 by cosmic apparently hasn't seen an update since August | 13:26 |
| howarth | which makes you wonder how seriously it is really being worked on | 13:27 |
| gpunk | for me it works just fine, gtx860m | 13:27 |
| howarth | did you install from a ppa or from the Software Update control panel proprietary driver tab? | 13:28 |
| howarth | there seems to be several alternative sources for the graphics drivers | 13:29 |
| gpunk | manually with apt , from ubuntu repo | 13:29 |
| howarth | the ones installed from Software Update actually required a hack to fully install | 13:29 |
| gpunk | but bumblebee didnt work, for info | 13:30 |
| howarth | so ppa:graphics-drivers/ppa? | 13:30 |
| howarth | if so what does your blacklisting for using nvidia look like? | 13:31 |
| gpunk | not ppa , but ubuntu repo | 13:31 |
| howarth | so with 'sudo ubuntu-drivers autoinstall'? | 13:32 |
| howarth | It is really hard to pin down which approach is currently even viable to try to debug further | 13:33 |
| gpunk | /etc/modprobe.d/nvidia-installer-disable-nouveau.conf:blacklist nouveau | 13:33 |
| howarth | and I assume you added no ppa's at all to install the nvidia drivers, right? | 13:35 |
| gpunk | yes | 13:35 |
| howarth | so what command did you use to install the working nvidia driver? | 13:36 |
| howarth | ie did you use the metapackage 'sudo apt-get install nvidia-driver-390'? | 13:38 |
| howarth | The Software Update control panel claims that the 390 driver is tested so I assume that is want I want to be debugging on cosmic | 13:39 |
| howarth | FYI, this on a 2008 MacPro with a EVGA FTX 680 flashed with the Mac ROMs. | 13:40 |
| howarth | Windows has no issue nor does nouveau under cosmic | 13:40 |
| gpunk | apt install nvidia-driver-390 nvidia-dkms-390 | 13:41 |
| howarth | but so far every combo that I have tried goes to completely black screen (as in backlighting off) whenever it gets past the Ubuntu splash screen | 13:41 |
| howarth | so it appears to be puking on gdm | 13:41 |
| howarth | no crashes in the syslog though | 13:41 |
| howarth | okay, I'll try your recipe tonight | 13:42 |
| gpunk | and remember to blacklist nouveau | 13:42 |
| howarth | one thing I am a bit unclear on is when the blacklisting takes effect | 13:43 |
| howarth | the boot is done entirely from a kernel image file | 13:43 |
| howarth | so do that blacklisting inhibit the bundling of nouveau into the kernel image or just its loading? | 13:44 |
| gpunk | while loadig modules it skips it | 13:45 |
| gpunk | and modules dont get bounded into kernel | 13:45 |
| gpunk | some of them are put in the initramfs thingy | 13:46 |
| howarth | According to https://superuser.com/questions/577307/how-to-get-a-list-of-active-drivers-that-are-statically-built-into-the-linux-ker one can check for the bundled modules | 13:47 |
| howarth | it would be interesting to know if on your machine the built kernel even has nouveau | 13:47 |
| howarth | I was wondering if that could be part of my issues | 13:48 |
| gpunk | those are the drivers , loadable drivers are modules | 13:48 |
| gpunk | no it doesnt , nouveau is a Module-driver not a driver-compiled-in-the-kernel | 13:48 |
| gpunk | you cannot have a driver compiled in AND loadable module | 13:49 |
| gpunk | for the same purpose | 13:50 |
| howarth | I haven't down kernel builds for awhile and ubuntu is pretty opaque on what it is doing | 13:50 |
| gpunk | well what i am telling you universal, nothing to do with ubuntu | 13:51 |
| gpunk | is* | 13:51 |
| howarth | okay, so the image only has a fbdev I guess until the boot load the actual modules from the system disk | 13:52 |
| howarth | I can't find the url at the moment but I swear I read somewhere a blurb about bionic/cosmic nvidia using nouveau for gdm | 13:53 |
| gpunk | nope dont worry :) | 13:54 |
| howarth | I've been trying stuff like https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-18-10-cosmic-cuttlefish-linux | 13:56 |
| howarth | which is weird that they keep updating that page yet never mentioning blacklisting at all | 13:57 |
| howarth | and the page was updated yesterday | 13:57 |
| gpunk | yes, as i said before, it should be automatic, but your case, you already tryed "things" | 13:58 |
| gpunk | oh, in thzt page, i just read it, THEY mention disabling nouveau too | 13:59 |
| gpunk | when you do stuff manually | 14:00 |
| howarth | well this card has two DVIs, a display port and HDMI so I have suspected that nouveau is shifting the nvidia driver onto another display port | 14:01 |
| gpunk | niet | 14:01 |
| howarth | I probsbly should also try a clean install of cosmic to test this as I am using an apt-get upgraded version of cosmic from bionic | 14:05 |
