Lots of people (including me) have been experiencing issues trying to connect to their yahoo messenger account via pidgin. The reason for this issues seem to be that Yahoo are updating their servers and are using a new authentication system?
Thankfully i found a workaround
So Ubuntu Intrepid Ibex turned out to be a bad experience on my dell m1330. Many things that worked out of the box with Hardy heron got broken on Ibex. Things like Finger print reader, bluetooth, Graphic Display, Audio, all had one problem or the other. I was able to walk around most of the issues, although some were just unfix-able (like the screen corruption that i get when i enable compositing metacity or compiz) could not be fixed.
When Jaunty alpha6 was announced with many folks on identica claiming it to be very stable i decided to make the switch. I have since been running Ubuntu jaunty jackalope on my laptop. People say that the grass on the other side is always greener,well that was how running jaunty on my dell m1330 turned out. It wasn’t perfect and although i noticed many improvements from intrepid ibex like faster boot, better notification system, better support for suspense and hibernation, they were also some huge show spoiler like the Intel graphic regression which seem to affect the Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) graphic chipset the most, causing the system to hard freeze requiring me to have to manually power down the machine. This issue got really bad that i had to downgrade to ubuntu hardy heron (which ran perfectly on my system) while i waited for walk rounds to the problem.
