Description of problem:
I tried to install Fedora 20 LXDE spin, but after livecd boot I got an unexpected behaviour as represented in the screenshot.
I tried to boot the livecd in basic video mode and I managed to install Fedora, even using a basic resoluzione of 640x480.
When I booted the just installed Fedora, I got again a similar behaviour like in the mentioned screenshot.
[*] 00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
[*]The package contains two xorg.0.log log files: one for the livecd session, one for the installed Fedora session

Hmm. The postinstall logs contain nomodeset on the kernel commandline, disabling the intel driver (both ddx and kernel). Do you see the same behaviour if you then remove that and replace it with drm.debug=6 from the grub entry when booting? Could you attach the Xorg.0.log and dmesg after doing so?

I get a black screen that shows only the mouse pointer.
