Gnome - oh no! Something has gone wrong

Johnburrell · 2014-07-16 22:07:03

I installed xorg successfully. I installed xinit, twm and xterm and when I type startx I get the 3 windows okay. I thought everything looked good so I installed gnome.

I created a .xinitrc which contains:

exec dbus-launch --exit-with-session gnome-session

but when I type startx I get the dreaded oh no!

Can anyone give me a clue as to where to start looking. I don't see anything obvious in /var/log/Xorg.0.log

I installed nvidia which is obviously working okay because xorg runs as it should.

Is it a hardware acceleration problem? If gnome finds no acceleration, it doesn't start and gives this message - is that correct?

TIA

Not an Installation issue, moving to NC...

Have you tried using just "exec gnome-session"?

You also can consider installing GDM https://wiki.archlinux.org/index.php/Gdm by
# pacman -S gdm
which is an easier way to start Gnome. After installing, enable the service
# systemctl enable gdm
and reboot. Gnome should start automatically after that.

By the way, how did you install Gnome? Via package gnome, gnome-shell, gnome-extras?

I opened an x window and typed exec gnome-session

I get these messages:

Xlib: extension "GLX" missing on display ":0"

gnome-session-check-accelerated: Helper exited with code 256

Here is part of the Xorg.0.log

Why does it load the Nvidia module and GLX but then unload it?

I can post the entire Xorg.0.log if requested

Bit more info available:

I added the minimal config file suggested in the nvidia wiki to /etc/X11/xorg.conf.d/

When I try and start xorg it fails with failure to find screens.

This is the tail of Xorg.0.log that results:

Can anyone interpret "Screen(s) found, but none have a usable configuration"?

What do I have to do to give the screen (it's a laptop) a usable configuration?

Thanks

Bit more research tells me that my laptop has a hybrid gpu.

lspci gives:

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
Subsystem: Micro-Star International Co., Ltd. [MSI] Device 1106
Kernel driver in use: i915
--
01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 870M] (rev a1)
Subsystem: Micro-Star International Co., Ltd. [MSI] Device 1106
Kernel driver in use: nvidia

So I suppose xorg uses the i915 driver by default. I assume this doesn't have the acceleration required by Gnome.

So the next question is : how do I force xorg to use the nvidia driver? When I try and do that via the 20-nvidia.conf file, it gives me the no screens found message, mentioned above.

Any suggestions anyone? (potentially helpful ones, rather than 'give up' ;-) )
