When I install Gentoo on my Medion laptop with an nVidia GeForce 440 Go video chip, I can't get a completely working X configuration. If I try the "nv" driver my screen doesn't fill up (which may be resolved by a certain XF86Config somewhow). However, I don't want to use "nv", I want the "nvidia" driver. If I install that, the following occurs. When I use the built-in LCD panel, start X and logout again, the console is no longer visible. I can type in, e.g. reboot or start X again, but I see nothing at all. I do use framebuffer (vgafb, not rivafb); but disabling it does not help and again, I want to use framebuffer. However, if I boot from an attached monitor, things are OK; I can start X and return to the console without any problem. Reproducible: Always Steps to Reproduce: 1. Use nvidia 44.96 driver as provided by Gentoo (r3) 2. 3. Actual Results: See above Expected Results: See above Other info will follow later (I'm using a differnet machine right now). Also bug #29336 to me seems different from this one, although the solution may be comparable.

Can you try a variety of earlier / newer nvidia-kernel releases and see whether that would help to resolve the problem?
Let me add that I have been experiencing this problem for several months, and I of course dis a lot of searches in the Gentoo forum. For example, I took part in threads 102145 and 102960 and also posted this problem myself in thread 93131 but no one found a solution yet. Further, I had a 2.4 kernel before on this notebook and it exhibited the same problem. All 2.6.0-testxxx kernels had it as well. So I'm pretty convinced that it is a driver problem. Maybe a certain combination of driver parameters may solve this; I already tried setting "UseInt10Modules" which seemed a suitable candidate but to no avail. So maybe you should forward this problem to nVidia?
OK I did try a few other kernels the last couple of days: mm-sources gentoo-dev-sources No luck.
And even a 2.4.22 kernel (gentoo-sources)... Still the same.
OK an update to the latest driver (53.36) solves this problem.
