[ltp] X11 is slugish

[Harry Mangalam]

This is a reported 'feature' with laptops, especially with thinkpads (see
the apmd discussion list).  I hadn't heard that it had such a good
correlation with anything before tho.  Interesting.  I'll try this asap and
post my results here.  I suapect that it does have something to do with the
apm settings/handling tho.. - Battery Power at startup -> reduced clock
speed to conserve power.  Theoretically, it should switch back and forth,
but it may be that the clock can't be throttled once it's booted up.

I have noticed related wocko-ness tho - if I shut the case with power
connected, the Xserver goes berserk (looks like a solar flare melted the
screen), but it works fine if I disconnect the power before closing the
lid.  I've seen this reported elsewhere (here?), but no real patches as far
as I've been able to tell.

First time it happened, I was completely bummed out, but a reboot took care
of it; unlike some postings to the apmd list, it once set to a clock speed,
it doesn;t seem to change after a 'sleep' and since I only reboot about
once every coupla months, it's not a big deal anymore...
