[ltp] Jaunty on Thinkpad R51

[Lucas Bxxx]

Hi,

sorry for taking so long to respond. Thanks for all the help.

I checked my Xorg.log and both the RENDER extension and the open
source radeon driver seem to load perfectly. The fglrx driver did not
work, I read somewhere that they removed support for my card in some
earlier version. The old versions will not work with my X.org version.

Maybe I'm expecting too much from Ubuntu. Windows XP was significantly
faster, but that might be just because the ATI drivers are that slow
on Linux and X.org itself is usually slower than the Windows stuff. So
it might be that what I'm experiencing is not unusual, but I still
wonder why X.org is by far the most active program on my processor
(when browsing with firefox for some hours, Xorg used 200 minutes of
cpu time, while firefox, usually pretty cpu heavy itself, is at 40
minutes). Displaying top keeps a nice cpu usage of 20% :). So, if
noone will have another idea during the week I will have to switch
back to Windows XP.

Greets, Lucas

PS: Actually I can even watch movies on this thing. Only some basic
gui elements like scrolling are really slow. X.org/GTK at its best?
