I have a Lenovo 460 with Ubuntu 11.04 on the machine. I am having similar issues where I am unable to boot into the new kernel, unless I am plugged in to the AC power adapter I have no issues booting into the OS. I have installed the latest graphics driver from AMD for my ATI switchable graphics.. Following this line-up to get the driver to properly install I had to Install the prerequisite packages:
$ sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases If you are using the x86_64 architecture (64 bit), be sure to install "ia32-libs" on your machine, if you do not it will not function $ sudo apt-get install ia32-libs Download the latest Catalyst package. This package contains both the 32-bit and 64-bit driver. Current Version is 11.6 $ cd ~/; mkdir catalyst11.6; cd catalyst11.6/ $ wget http://www2.ati.com/drivers/linux/ati-driver-installer-11-6-x86.x86_64.run $ chmod +x ati-driver-installer-11-6-x86.x86_64.run Create .deb packages. $ sudo sh ./ati-driver-installer-11-6-x86.x86_64.run --buildpkg Ubuntu/natty Install .debs. $ sudo dpkg -i fglrx*.deb Generate a new /etc/X11/xorg.conf file Create the ATI version of the Xorg.conf file. This is a Generic Configuration... This works great for my machine which is a Lenovo Y460 $ sudo aticonfig --initial -f After just reboot your machine After following this proceedure I am still unable to start Ubuntu without having to be plugged into the wall... I hope the fix will come soon... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/775950 Title: fixing recursive fault but reboot is needed! upon boot (always reproducible on battery only, but sometimes on AC too) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/775950/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
