Feedback on the HP ZBook 14 G2 - ChicletW

Asked by Peter Mansvelder

I have recently purchased 4 HP Zbook 15G2 machines, and after some troubles, managed to install Ubuntu 14.04 on it. I encountered the following issues:
- The machine was delivered with 1 1TB harddrive (HGST Travelstar 7K1000), visible as /dev/sda, and 1 256GB SSD (SanDisk SD6PP4M-256G-1006), visible as /dev/sdb. I wanted to install the OS on the SSD, and with the standard Ubuntu 14.04 installer I managed to do so, but after installing and rebooting the system kept booting in PXE mode, and even after manually choosing the SSD as the boot device, it refused to load the OS. I finally succeeded by first removing the harddrive (relatively easy on this machine), and then installing the OS. The ssd was still visible as /dev/sdb all through this process. After reinstalling the harddrive, it was visible as /dev/sda, and I could manually format it and make it usable.
- The video card was recognized as a nvidia card:
01:00.0 VGA compatible controller: NVIDIA Corporation GK208GLM [Quadro K610M] (rev a1)
01:00.1 Audio device: NVIDIA Corporation Device 0e0f (rev a1)
It was initially driven by the nouveau driver, but that refused to work with external displays: only 1 external monitor on the VGA connection was recognized, all the other ports (DisplayPort), DVI by using the HP Dock were not. I sometimes got a monitor to start up after rebooting, but then the driver crashed while logging in. Also, after the initial install, the resolution was reduced to 800x600, but after updating that was fixed.
When I installed the nvidia drivers (nvidia-346) using the control panel, all monitors were correctly recognized.
- The 4G modem: this was not recognized, but visible as an HP device with lsusb:
Bus 003 Device 003: ID 03f0:581d Hewlett-Packard
After some googling, I found that issuing the following commands made it work:
modprobe qcserial
echo '03f0 581d' > /sys/bus/usb-serial/drivers/generic/new_id
service modemmanager restart

Just thought I'd like to share this information for future users.

Friendly greetings,
Peter Mansvelder

For the installation issue, you might need to select "Something else" to do manual partitioning. Install the grub on sda, "/" on sdb (in the very beginning of your case), it's nice to know that you have solved this issue, and thanks for sharing these notes.

Can you help with this problem?
