I am all for being part of the test group, and its great that they are
working towards fixing X. Is it in any way possible that there could be
ppa's made for the old intel drivers that make jaunty usable again for
release day ? That way , even if its not by default, users can be
directed to
Shipping the older driver version has got to be a serious thought, I
think - at the moment the user experience on one of the most common
embeded video chip sets will be 'Jaunty broke my system'.

I agree with Tom here. I have a G35 integrated chipset and found the
same problems as reported here with regards to abysmal performance in
compositing managers. In addition, switching to UXA simply does NOT
work. The server reports not being able to find modes for the screen
(see attached
On the other hand, using the backport referred to by Micheal brings only
small performance gains over the 2.6 driver on my hardware. (G35)

I agree, I installed Jaunty on my laptop, the good thing was that the
@Bartek: Absolute performance improvement is only one metric. The other
side of the coin is that the new driver either sucks 30% of CPU, or uses
an experimental graphics sub-system (UXA) that has problems all of its
own for some (most ?) people. Given there is no benefit to the newer

Since RC is already released and the issue is still there, I think
there is almost no chance of getting it fixed before the final release
!!!
So, I have reverted back to Intrepid and I am happy now !
Users having these intel chipsets should be strongly discouraged from
upgrading/installing
Apparently, you can revert to the old Intel Driver, which should fix the
problem:

Thanks Michael - I reverted to the old driver as indicated in your link,
got flawless performances, no apparent glitch, and it seems to be
stable. Maybe this driver should be made the default for Jaunty?

I strongly suggest this issue to be addressed, one way or the other.
Kubuntu has now reached RC status, and the user experience on Intel
chipsets is just the worst one could have on Kubuntu (Intel 945GM).
Without EXA or UXA performance is terrible or glitches appear. Enabling
EXA slightly speeds
Totally agree with Gnurou. You can't release a version that's known bad
without putting the workarounds in BY DEFAULT. However there might be
light at the end of the tunnel (or buffer, or pipe :-) )

Nope. UXA still freezes with 2.6.28-11. Still won't even give me a

Hi have the 'magic' line, to enable UXA. It does make a significant
difference but the performance is still sluggish. In comparison at least
to Fedora 11 Beta which is afaik using X server 1.6. I am trying to
work out the differences at the moment. Will write more when I have some
answers.

My X4500 is also still fairly sluggish compared to intrepid with
UXA/DRI2. Tried out Fedora 11 Beta for comparison which performed like
intrepid did. I'm not sure what the difference in their stack is or if
that bit of information is in anyway helpful. I am happy to reinstall it
and gather
@Rick Spencer
If the 'offical' stance is that unless you add the magic two lines (or one
line, or whatever the fix is) to Xorg's config file KDE will suck in Jaunuty,
this should be done *by the upgrade system*, otherwise the user experience will
be 'the upgrade broke my system'.

I also tried these options but they caused major visual corruption when
trying to enable a 2nd monitor using xrandr after logon.
I set up these options and I use an external 2nd monitor and it works ok, but
it does corrupt horribly
I am installing Mandriva 2009.1 rc2, and it gives me the option, Use EXA
in place of XAA ( Better performance for rendering and composite )
So that means EXA would be better? I dont know wgat UXA is, but Mandriva
has reputation off one off the best hardware support under Linux.

Not possible on my system.
UXA is not going to be enabled by default in Jaunty, since it is not stable.
In my case, I am experiencing frequent X freezes.
So, to stress the point, using UXA is out of question, atleast for now.
If this bug can't be fixed before the final release, I would suggest going

Well, both solutions are not satisfactory.

It's not like EXA is really an option as it makes working really slow.

Why is the importance of this bug not at high?

Everyone knows, that such chips are the most frequently used in notebooks.
