So what went wrong, exactly?

[Tom Horsley]

When I installed fedora 21 alpha a while back, I was able
to get my nvidia GTX 750 Ti to work fairly well with binary
drivers from rpmfusion.

I've just re-installed 21 from the workstation live iso,
and all I can get with a fresh install is the screen that
says "Oh no something has gone wrong!".

So X is working well enough to display that screen, but
it would be nice to know what has gone wrong (and, of
course, I have no useful log files since systemd has
hidden all info behind cryptic binary files now).

Any clues how to investigate this?

I had Nvidia cards in my earlier desktops running linux.
got very
frustrated with driver issues.. My latest desktop now has AMD Radeon
card, running opensource driver.

With X in F21 there's no /var/log/Xorg*log any more so to get the X log:
journalctl -b -u gdm

(you probably already know this).

Nine times out of ten when I got that message while using the nvidia
proprietary driver it turned out to be something wrong with the 3D
acceleration failing due to the bundled libGL.so.* not being loaded by
ldconfig for one reason or another. So check:
journalctl -b | grep accel
journalctl -b /usr/bin/gnome-session

right after you get the error message.

I hope that helps.

I am using gdm with the intel driver, and I don't have an
/var/log/Xorg.*.log; the X log is sent to the journal, maybe that's
specific to gdm?

It is specific to gdm:

Yep, but that only shows up *after* you actually have a working nvidia
driver installed, prior to that using vesa with horrible resolution
I got no Xorg.0.log (though I did get xorg junk in the journal).

Anyway, I've been investigating, and submitted this bug:

https://bugzilla.rpmfusion.org/show_bug.cgi?id=3451

Apparently the akmod-nvidia package I tried first didn't really
build the driver. When I tried the pre-built kmod-nvidia, I
at least get video of the proper resolution, but I appearently
don't get 3D support.
