Description Germano Massullo 2014-11-13 14:07:45 UTC 
Description of problem:
I tried to start Fedora 20 KDE spin, but after livecd boot I got an unexpected behaviour, identical to the screenshot of bugreport https://bugs.freedesktop.org/show_bug.cgi?id=84739 with the only difference that I started KDE instead of LXDE.
I tried to boot the livecd in basic video mode bug the result is the same.

# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

I am going to attach Xorg.0.log and dmesg of the following kernel boot options:
- "normal boot"
- nomodeset
- drm.debug=6

Comment 7 Chris Wilson 2014-11-13 14:17:33 UTC 
The problem in this case is that plasma-desktop dies after running out of memory (completely exhausts RAM + swap). I don't think there is a driver bug (unless you are sure it is a driver memory leak).
Comment 8 Germano Massullo 2014-11-13 14:24:24 UTC 
You are right. Indeed I tried to start LXDE and it starts flawlessly... I think we can close the bugreport
Comment 9 Chris Wilson 2014-11-13 14:32:20 UTC 
Feel free to reopen if you find anything suspicious in how KDE behaves.
