"The first impression I got post-installation was that
it was slow when desktop effects are turned on. After some trivial
googling, we find that Jaunty's issues with Intel graphics chipsets
are well-documented. The Jaunty Intel Graphics Performance Guide
Howto documents how to get over this, albeit in a pretty
non-standard way. The recommended 2.6.30 kernel to be installed
isn't available from any ready Jaunty backport PPA repo, so that
was downloaded separately and installed using dpkg -i. An
additional experimental PPA has to be added to take advantage of
recent X improvements. The default acceleration method enabled EXA
is practically useless for us if we want to turn on desktop efects.
This necessitates a switch to the newer (and less stable) UXA.
Fortunately, this switch has worked well for us, for the most part.
"Even then, some niggling issues persists. KDE's Plasma would
crash every now and then. And when it doesn't crash, some other
weird issues would crop up, such as all text on my panels
disappearing after about 12 hours of uptime. Fortunately,
restarting plasma-desktop is trivial so this is just a minor
irritant. Still, one wonders how would a user who does not know how
to restart Plasma would take this."
