I upgraded to the nvidia-drivers version 169.12. Now i cannot switch to TTY, after saying this in #gentoo on irc.freenode.net there seems to be a few with this issue.
No dmesg errors, no Xorg errors in the log. Happens if i start X from both a TTY and the GUI
Steps to Reproduce:
1.start X (both from TTY and GUI)
Black Screen, not able to do anything apart from Switch back to the GUI
Given the TTY login prompt
You can use nvidia-bug-report.sh to generate some information to e-mail over to

I experienced a similar problem, might well be related to this bug and happens with 169.12 but not with 100.14.19 (that's why I changed back to that version). I'll just attach the mail I sent to nvidia's bug address:

Someone from nvidia answered and told me they are aware of this problem and that it'll be fixed in the upcoming 173 release.
Do with this information whatever you want, I didn't think it was worth its own bug report, since upstream is aware of it already.
Thanks for letting us know of the outcome. For the record, there is a 173.08 beta ebuild in the portage tree. It is not supported (and far from perfect), but if you are experimenting with different driver versions it might be helpful at some point.
Happens again with:
0: /usr/bin/X(xf86SigHandler+0x6a) [0x48dc8a]
1: /lib/libc.so.6 [0x2b69aa28b430]
2: /usr/lib64/xorg/modules/drivers//nvidia_drv.so(_nv000754X+0x6a) [0x2b69ac8a010a]
Fatal server error:
Caught signal 11. Server aborting
Please reopen since it seems to be the same bug basically. I haven't tried the 177 drivers since they're still hardmasked because they're unsupported.
Please follow the instructions with the ebuild. That is to use the nvidia bug-report script and open a thread on nvnews.net so nVidia staff can investigate. As I do not have the driver source I am not in a position to help you.
