ok i should post all my problem... i installed with no apci option kubuntu 10.10, after i had win 7, kubuntu installed succesfully and then restart, but when it was starting show this problem... failed to get i915... so i read that i can enter kubuntu by doing in the start some changes linux /boot/vmlinuz... ro quiet splash to linux /boot/vmlinuz... ro nomodeset quiet splash... kubuntu load but no graphical enviroment... so there i am, i see everything like a console, i logged in and i tried sudo sh -c "echo blacklist intel_ips >> /etc/modeprobe.h/blacklist.conf" and i got this error sh: cannot create /etc/modeprobe/blacklis.conf : directory nonexistent i tried to rewrite it i thought i wrote it wrong, so i wrote it whitout space before the sh... sh-c"... and i get this sh: illegal option h... i couldn't put it onto black list =(.... (sorry again for the bad engish)

Blacklisting it don't solve the problem, it hides it.

My laptop still gets high temperatures, with windows 7 that doesn't happens

I've just successfully compiled and booted kernle 2.6.38-rc4. I was disappointed that the intel_ips / i915 symbols error message still appears at boot time.

HP Elitebook 8740w. Still can't run compiz.

I managed to get it work by applying the patch that can be found at
http://lists.freedesktop.org/archive...er/009017.html and then following the steps in http://blog.avirtualhome.com/2010/11...verick-kernel/ before starting the build of the kernel apply the patch and then build the kernel install the deb files and thats it. I am running this on KUbuntu 10.10 on a DELL Latitude E5510 and the kernel that I patched was Ubuntu-2.6.35-25.44 from the ubuntu git repository. So in the manual above when running the command git tag -l | sort -V I checked out the tag Ubuntu-2.6.35-25.44.

My dmesg after the fix:

I noticed that the start up time might be just a tiny bit longer.

Great, but a bit difficult for me Has your Ubuntu better graphics performance?

[UprightMan]

Apologies for what is probably an obvious question (I'm still learning the Linux ropes at the moment), but how do I apply the patch that 25an has shown us?

That error message each boot-up is eating away at my sanity and I'd very much like to correct it haha.

[de_Selby]

Thanks for that 25an! I've compiled a new kernel and it's working perfectly.

I've uploaded a deb of the kernel for anyone else to download so they don't have to go through the effort of compiling. The link is below:

I haven't used 4shared before, hopefully they don't have a limit on the no of downloads.
