Initially, both the Intel integrated graphics and the Nvidia card will be active, consuming a lot of power, so you probably want to install bumblebee and bbswitch. With this laptop, the packages nvidia, bumblebee-git and bbswitch-git are working fine.
From the xps 15z, wiki page, it is reported that using the Intel card without any modifications can result in poor video performance. A quick fix that does not make things worse for the 14z is to edit
/boot/grub/menu.lst, and append the following to the
kernel /boot/vmlinuz... i915.semaphores=1
First try to install.
and see if the following command works successfully:
Normally it should.
Special trick for acpid
If you wish to use acpid for handling the event for plugging/unplugging the ac adapter, you should know that the script does not handle it properly. For some reason, acpi_listen does not report a second argument in AC|ACAD|ADP0 but ACPI0003:00. In
/etc/acpi/handler.sh, you can modify these lines:
ac_adapter) case "$2" in AC|ACAD|ADP0) ...
ac_adapter) case "$2" in AC|ACAD|ADP0|ACPI0003:00) ...
If this does not solve your problem, you should be able to see what event is triggered by plugging/unplugging the laptop using acpi_listen.
USB 3.0 has not been tested but should be working. The USB 3.0 driver in the Linux kernel is located in:
