XFCE4 either crashes the computer, or has a black screen, or works.

I got a problem and I've no clue where to start debugging - I'm using lightdm and xfce4 and when I try to login, it shuts down and restarts. I disabled lightdm with systemctl and tried doing startx by myself, same thing, so it's probably not the dm. It only crashes around 80% of the time, other times it loads fine. Sometimes it doesn't even crash but just freezes, can't even switch TTYs.

I have a log of Xorg.0.log if it helps: http://ix.io/1KP0

Re: XFCE4 either crashes the computer, or has a black screen, or works.

[    77.210] (II) modeset(0): Refusing to try glamor on llvmpipe
[    77.257] (EE) modeset(0): glamor initialization failed

sounds not too good.

Is there any SIGILL in the journalctl for lightm (indicating alack of SSE2 problem)?

What is your graphics card?

/proc/cpuinfo says that sse2 is supported, if it helps the CPU is an Intel Atom N2600.
lshw says "Atom Processor D2xxx/N2xxx Integrated Graphics Controller".

How do I check for Sigill?

Re: XFCE4 either crashes the computer, or has a black screen, or works.

You would see a SSE2 releated error when exetuing 'journalctl -b0 -l' (for the process lightdm or one of the greeters).

'lshw' (package lshw) or 'lspci' (package pciutils) can show you the graphic card.

Do yo get a login prompt, i.e. lightdm?
Because if yes, then nothing is wrong with Xorg.
I usually test XFCE4, so I thinkg it's not a problem there

What are the contents of /var/log/lightdm/lightdm.log?

Is lightdm and lightdm-gtk-greeter installed?
