 Posted: Mon Jun 19, 2017 9:12 pm Post subject: NVIDIA Optimus fails after revdep-rebuild |
 |
|
Hello,
I had NVIDIA Optimus working without issues, then (because of ABI changes) I did the suggested revdep-rebuild
| Code: | | revdep-rebuild --library 'libstdc++.so.6 -- --exclude gcc' |
and after that, it did not work anymore (more exactly, I don't get the graphic SDDM login stuff anymore, but only a text based login, and "/etc/init.d/xdm status" returns "crashed").
The same symptoms are described here. The eclean-solution proposed did not help. What I have not tried is switching "eselect opengl" to xorg-x11 and running another revdep-rebuild (300 packets!), but from gentoo IRC chat, people have suggested no to try it (mainly because that solution is too old).
Things I've tried and infos:
- It does not look like the emerging might have overwritten important config flies (at least, I can not see any candidates that don't have CONFIG_PROTECT).
- I rebuilt the kernel and then the nvidia-drivers without success.
- Xorg.0.log
- dmesg
- The PCI bus ID matches the one from "lspci -k" , so it's correct.
Can someone please help?

How are you running your programs? Does optirun or anything else produce output? Are you in the bumblebee group?

| I don't have an optirun command. I use modesetting, like described in the NVIDIA/Optimus wiki page, not bumblebee. |

I found out that I had xorg-server 1.19.3 installed, and the NVIDIA/Optimus wiki page recommends a more simplified version of xorg.conf. I changed xorg.conf and it worked.
Lesson: When something on your Gentoo system does not work read the full article about the topic carefully (even stuff that looks like it would never change or would not matter) and check carefully that your system still complies with everything. No criticism about Gentoo, it just seems to be a practical rule.
One open question: The whole thing worked before the revdep-rebuild, which means that my xorg-server version might have changed by the revdep-rebuild. Can revdep-rebuild - under some circumstances - emerge newer versions of packages, even though you didn't do an "emerge --sync"? |

[url]I've written an article on how to configure bumblebee on gentoo linux on my website and I'm constantly updating it (hopefully will add it to the gentoo wiki once I confirm it's 100% working), you may want to check it out:
https://www.dotslashlinux.com/2017/06/04/setting-up-bumblebee-on-gentoo-linux/
A couple of users have found it helpful, give it a shot and tell me what went wrong 
Good Luck
