"Oh no! Something has gone wrong."

[Oliver Ruebenacker]

     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

  Really? That's so funny.

  Certainly it is the most useless error message I ever saw. It should at
least indicate form which direction the error came from. Maybe the author
of that piece of software felt it too embarrassing to reveal the source of
this message.

     Best,

  Found no reference of nv or nvidia in /boot/grub2/grub.conf. It also says
in that file not to edit it because it will be auto-generated.

  AFAICT, nvidia driver was never installed. Ran the installer a few times,
but it always failed. I had put a "blacklist nouveau" in
/etc/modprobe.d/blacklist.conf, but removed that long since.

     Best,

Take a look into /boot/grub2/grub.cfg, most probably the uninstaller
didn't restore the kernel boot parameters which has been placed in
order to get the nv driver to work. Looks like you'll have to do this
manually (= remove the nouveau blacklisting etc.).

One solution I dound with difficulty is that Alt+F4 (I think) kills
the "frowning computer" and (at least in my case) leaves you with a
working system. Surely something to be improved in the UI....

  My system boots again into KDE after this:

sudo yum groupinstall kde-desktop-environment
sudo systemctl enable --force kdm.service

  Now back to the original problem: how I can make KDE work with two
monitors again.

     Best,

And the first step, of course, is a more informative error message.

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.
