| With ''2GB NVIDIA GeForce GT 525M Graphics Card with Optimus'' installing nvidia-current drivers from ''restricted drivers'' causes the loss of compositing. Moreover running nvidia-xconfig crashes X on the next reboot (fix it with {{{sudo rm /etc/X11/xorg.conf}}} and reboot). This happens because '''you need Bumblebee to make it works''', more explanations follow the suggested procedure. | With ''2GB NVIDIA GeForce GT 525M Graphics Card with Optimus'' installing nvidia-current drivers from ''restricted drivers'' causes the loss of compositing.

== Fix various glitches == '''The following fixes are needed to boot correctly after installation.''' Otherwise the laptop will freeze before login screen. For a first boot hit ''e'' on the first option while on grub screen and add the following commands to the boot sequence just after "quite splash". '''pcie_aspm=force acpi=noirq i915.semaphores=1''' To make it persistent add '''pcie_aspm=force acpi=noirq i915.semaphores=1''' to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub. Then run the following command: ||# update-grub|| And reboot. This fixes ACPI issues, lowers power consumption and 1-2 second regular freezes of your video card. |

* The HDMI is physically connected to the nVidia card -- by manually changing the xorg.conf, it is possible to start X on the nVidia card only, getting the HDMI video (at the cost of inactive main laptop screen and the Mini Displayport output).
