I have a new installation of Debian 8 and the KDE Desktop that isn't
working. As the system boots it asks for user and password then as the
KDE startup icons appear in a box in the middle it always locks up once
the third one appears.
I have additional memory on order but presently the system has just 1GB
of RAM. Is this the likely source of my problem?
1G should be enough to get by on. Tell us more about your hardware, the
gfxchip in particular, but also CPU and chipset. lspci will give a summary if
you do Ctrl-Alt-F2 and login before it "locks up".
