After downloading/ burning the ISO the install went smoothly once I put back in order the boot menu… I have a second hard drive a m-sata drive but most Linux/BSD installers do _NOT_ like to boot on second disk first… (by default)
Wifi issue
Once partitions are crypted, installation is made, after reboot everythink was working by default. However I had to put back on its base the laptop so the default ethernet connection goes on and then I could set up wifi connections… a bit painful but not really difficult to perform.
Xorg customisation
On XFCE, the basic DE on Qubes OS R3.2 the tracknav of my thinkpad were not automagically configured as on Debian/Ubuntu. So in my [personal] VM I launched Firefox, got to this page then copy pasted the /etc/X11/xorg.conf.d/20-thinkpad.conf content into /home/user/test, then copy this file back to dom0 ( the admin VM):
qvm-run --pass-io personal 'cat /home/user/test' > ~/test
Then modify Xorg files with:
sudo su cat /home/warnaud/test > /etc/X11/xorg.conf.d/20-thinkpad.conf
copy/pasting between VM to dom0 is a bit of a pain
