| darkxst | I played with the KMS modesetting in the new nvidia drivers today, couldn't get plymouth to work, but it should in theory since I got a DRM DUMB BUFFER working after boot | 10:38 |
|---|---|---|
| darkxst | and non-root Xorg seems happy enough but mutter segfaults creating the cogl framebuffer | 10:39 |
| mamarley | It doesn't support fbdev, which is probably why Plymouth doesn't work? | 10:39 |
| darkxst | mamarley, plymouth doesnt use fbdev | 10:39 |
| mamarley | Ah, OK. I don't use Plymouth, so I was only guessing. | 10:40 |
| darkxst | but apart from that, the ABI verison of the drm module is causing problems (i.e. there is a modprobe ndivia_drm modeset=1, that fails) | 10:40 |
| darkxst | and also (probably unrelated) nvidia-persistanced is broken on my system due to user permissions, it seems to think that the nvidia-persistentd user is ID 133, when in acutal fact its 151 or something | 10:40 |
| mamarley | Sounds like your installation is screwed up somehow. | 10:41 |
| ricotz | darkxst, just for completeness you are using the 364 ppa packages, not installed it yourself? | 10:41 |
| darkxst | ricotz, yes ppa packages | 10:42 |
| darkxst | systemd-udev calls "modprobe nvidia_drm", but locally only "modprobe nvidia_364_drm" works | 10:44 |
| darkxst | I hacked around that with symlinks (and copying modules into initramfs) was able to get to the point of running and also (probably unrelated) nvidia-persistanced is broken on my system due to user permissions, it seems to think that the nvidia-persistentd user is ID 133, when in acutal fact its 151 or something | 10:45 |
| darkxst | bad paste | 10:45 |
| darkxst | running https://github.com/dvdhrm/docs/tree/master/drm-howto | 10:45 |
| darkxst | that works (and is almost identical to how plymouth works) | 10:45 |
| darkxst | plymouth passed the drmGetCap call (same as example above) | 10:50 |
| darkxst | but then failed trying to setup the connectors and/or crtc's | 10:50 |
| darkxst | anyway I will play around more with the plymouth side of things after beta-2, but can you guys look at loading the nvidia-drm into initramfs and fixing the modprobe error? | 10:58 |
| darkxst | this: Mar 23 10:41:07 duhast systemd-udevd[475]: Process '/sbin/modprobe nvidia-drm modeset=1' failed with exit code 1. | 11:05 |
| mamarley | tseliot: ^ | 11:39 |
| tseliot | darkxst: where did you see that modprobe nvidia_drm modeset=1 fails? | 11:49 |
| darkxst | tseliot, with 364 drivers and kernel param nvidia-drm.modeset=1 | 11:51 |
| darkxst | but I also get the same if I rmmod and the try to modprobe | 11:51 |
| tseliot | darkxst: it works fine here (on 16.04) | 11:52 |
| tseliot | even if I modprobe manually | 11:52 |
| tseliot | darkxst: what's the error when you modprobe the module? | 11:53 |
| darkxst | tseliot, I can't try again right now, but pretty sure it was "can't find nvidia_drm module" or similar | 11:54 |
| darkxst | then It work with `modprobe nvidia_364_drm` | 11:55 |
| tseliot | darkxst: ok, I can see that the alias for nvidia-drm is missing | 11:55 |
| tseliot | that should be the problem | 11:55 |
| tseliot | (nvidia-modeset has an alias) | 11:55 |
| darkxst | tseliot, then they need to be in the initramfs | 11:55 |
| tseliot | darkxst: yes, the aliases will be there. All but nvidia-drm are | 11:56 |
| tseliot | I'll fix that | 11:56 |
| darkxst | tseliot, no the modules, so plymouth can get them | 11:56 |
| tseliot | I'm not sure why things work here though | 11:56 |
| tseliot | darkxst: we don't do that in Ubuntu. You can add them manually if you like | 11:57 |
| tseliot | tjaalton: ^ do we do that with intel? | 11:58 |
| darkxst | tseliot, I think all the other drm drivers are in the initramfs | 11:59 |
| tseliot | (I could be wrong) | 11:59 |
| darkxst | nvidia-drm isn't because its like a day old | 11:59 |
| tjaalton | yep | 11:59 |
| tseliot | oh, ok then | 11:59 |
| tseliot | I'll fix that up | 11:59 |
| darkxst | tseliot, ok, thanks! | 12:02 |
| ricotz | tseliot, watch out for hyphen vs underscore | 12:03 |
| tseliot | ricotz: yes, I know | 12:07 |
| ricotz | tseliot, what I meant is "alias nvidia-modeset $(PKG_module)-modeset" or "alias nvidia-modeset $(PKG_module)_modeset" ? | 12:10 |
| ricotz | so the existing hyphens seem wrong :\ | 12:12 |
| tseliot | ricotz: I see what you mean. I really don't remember why things are the way they are (it's been a while). I can certainly look into that | 14:35 |
| tjaalton | scr | 18:13 |
| tjaalton | bah | 18:13 |
