 |
|
Hello all, I'm having a strange problem when trying to use nouveau drivers for my NVidia card.
First of all, after enabling the nouveau support in the kernel I started getting the "waiting for uevents to be processed" behavior (https://forums.gentoo.org/viewtopic-t-955618-highlight-waiting+uevents+processed.html). Escaping out of it with Ctrl-C, I startx, but get a flickering screen. The X server is working and displaying keyboard actions but the flickering slows things down greatly. The Xorg logs do not contain error lines, but the lines

| Do you have several graphics chips connected to your system? What does "lspci -k" say? |

Through out keyboard and mouse and insert evdev in this line
| Code: | | INPUT_DEVICES="evdev" |
of your make.conf, if you haven't already.
For this case, recompile your world with -DuvaN options.
Just a shot in the dark, cause the syntax of your xorg.conf.d/10-main.conf
Much success, Andy.

Not sure if you're still running into this issue, but this may help the next person looking for info on this error.
I ran into this when I was trying to have nouveau and nvidia proprietary coexist but use nouveau exclusively (compiled nouveau as a module and prevented nvidia from being loaded via /etc/modules.d or /etc/modules-load.d)
Everything ran cool with Xorg but I was seeing that "removing GPU device error" along with a lot of fuss coming from journalctl and syslog about the nvidia module trying to load while nouveau had already registered the card.
What I observed was Xorg listening to udev constantly add and remove the nvidia GPU, this was confirmed by the spam coming from 'udevadm monitor.'
Later I learned that the nvidia-drivers package installs a udev rule in /lib/udev/rules.d/99-nvidia.rules that was causing this constant add/removal in udev.
Commenting out the rules in that file stopped the spam and Xorg mesasges for me. When I want to use nvidia I'll probably add those back.
With that said, I don't know what the context of your install is like (all I know is you're trying to use nouveau) but I was experiencing this issue and that was how I solved it.
Hope this provides some help to some without having to dig like I did (although you should, its good for you  )
