Okay, that information is a lot more useful. I recently ran into this
myself on another machine with an Nvidia videocard in it -- and a kernel
update caused exactly these errors to appear and the grahpics failed to
start.
First, here's what I did that fixed the problem that I had:
- modify /etc/modprobe.d/i915-kms.conf to turn off kernel modesetting:
options i915 modeset=0
- modify /etc/modprobe.d/blacklist.conf to blacklist nouveau driver:
blacklist nouveau
What's going on is this: the newer kernels try to load the open-source
nouveau driver by default, which is capable of getting 3D to work with
older Nvidia cards that are difficult to support with the proprietary
drivers. Unfortunately this also involves turning on kernel mode mode
setting (KMS), and when this is active the "normal" 2D drivers such as
"vesa", "nv", etc, cannot load. The result is that if the nouveau
driver tries to load and doesn't work, nothing else will either.
The other thing to know is that this likely wasn't something you did --
i.e. I don't think this is a matter of missing files. Rather I think
this is due to a kernel update that tries one of the KMS drivers
(nouveau, raidion, Intel i915, etc), fails, and then none of the
"normal" X.org drivers can load, either.
