problem still persists. I need to use an older kernel to get full nouveau support for my graphics card.
There's zero evidence in there of drm or nouveau being loaded at all, I suspect something has happened to your install. If you exit X, and try "modprobe -r nouveau; modprobe nouveau modeset=1" from the console, do things come up? I also notice "nvidia" in the module list in lspci output.. Which means you'll need a "modprobe -r nvidia" too. Make sure you've uninstalled the NVIDIA binary driver too, and removed anything in /etc/modprobe.d/ that might blacklist nouveau. you're right! Thanks a lot. Now how do I add the driver to load automagically with the new kernel? I took a look at the grub.conf file and the various entries seem to match as far as args. I suspect if you do the following, it *should* work: - uninstall the binary driver - remove the modprobe.d stuff - load nouveau as mentioned above - run 'dracut -f' I found an errant file in /usr/lib/modprobe.d/ that the nvidia installer placed there that disabled the nouveau driver (as opposed to /etc/modprobe.d). removing that file and following your instructions above allowed everything to work as expected. Thanks again!! :) |
