Hello,
After a failed attempt to install the manufacturer's nvidia driver,
my system (Fedora 19, with both Gnome and KDE, on a Lenovo ThinkPad
T430) does not reach the graphical login screen any more, but instead
ends up in a white screen with a frowning computer cartoon and the
message
"Oh no! Something has gone wrong. A problem occurred and the system
can't recover. Please contact a system administrator."
I can still do Ctrl-Alt-F2 to log into text mode. When I try
startx, I get an empty screen with white or black background and a
mouse cursor, extending over my two screens (laptop and external).
When I try startkde it says:
$DISPLAY is not set or cannot connect to X server.
The only error in /var/etc/X11.0.log is:
Failed to load module "nv" (module does not exist, 0)
In /var/log/messages, there are a bunch of lines like (I'm typing
by hand):
gnome-session[2658]: (gnome-shell:2949): Cogl-WARNING **:
./driver/gl/cogl-framebuffer-gl.c:561: GL error (1282): Invalid
operation
Could not find a solution on Google.
I already reinstalled a bunch of packages, including cogl, gdm,
gnome-shell, @kde-desktop, xorg-x11-drv-nouveau, kernel, but no change.
Any advice? Thanks!
Best,
Oliver
I remember running into this problem over time with Fedora 16,18 and
19 so did a fresh install using the standard nouveau driver, then
when the system was working, followed the instructions on the Fedora
page to install the nvidia driver.
Apart from a slightly smoother movement of windows and terminals, and
I usually have quite several open at once, I have seen no real
benefit from the nvidia video driver.
I believe nvidia has released helpful code to the nouveau devs but
have no knowledge on the benefits or other.

The major benefits from the Nvidia driver for me are working power
management and working vdpau, which lets me play 1080P video smoothly on
an old Intel core2 cpu. With the nouveau driver, my video card runs
about 30 degrees hotter, and HD video looks like crap. Of course, 3D
rendering is much much faster with the Nvidia driver, but I don't play
games.
