Hi Ross, I am keen on getting a Lafité II so have a vested interest in this thread. I guess you have checked whether anything HERE is relevant? No specific info for Stretch on it unfortunately. Just wondering what desktop environment you are using and also which kernel?

Is everything else working ok? I would prefer to install LMDE as I like an easy way of running Debian Stable but I will run Testing if I have to.

Hi Miks,

im only really having two issues:
1. suspend to ram not resuming
2. power button not being detected (wtf?), no acpi events, key events or anything

when setting up the system you will need the firmware for the intel wireless card on a pen drive: think i got it here http://www.intel.com/support/wireless/wlan/sb/CS-034398.htm

i think the segfaulting vbetool is a red herring, the system is still up and running (can shell into it) but the screen is black but is the backlight is on

in other news, it boots from cold into XFCE4 about 4 seconds, weighs nothing and is very shiny, touchpad comes with two finger scroll out of the box and has "soft" left and right buttons as well as two finger right click

ive just tweaked the touchpad settings using synclient, now the soft buttons are gone and three fingered click acts like the middle button

Thanks for that. It may be worth installing a later kernel with better support for Skylake processors. I am not sure what the latest is for Stretch. Have you used smxi? You could run it to check what Liquorix kernel is available and try it to see if it fixes the suspend issue.

got suspend to ram working, these are the settings s2ram needs to use

s2ram --acpi_sleep 3 --vbe_mode

this is currently running against a 4.2 kernel

then it took me a day to work out how to make systemd use s2ram for suspend... im a sysV init guy really... guess that makes me old.

Just ordered it! I will be trying to get Linux Mint Debian Edition to work, which still uses sysvinit, not that I have anything against systemd, because I have not tried it yet. If LMDE doesn't work, I will install Debian Stretch with Cinnamon desktop.

Well, it was a painful wait of 5 weeks and 2 days, but it did arrive yesterday. I have mint debian edition running on it, after installing the 4.2 kernel and various firmware packages from Jessie backports. The main problem to fix is that hardware acceleration does not work, and I have drawn a blank on getting it working. Suspend works sometimes and resumes sometimes, probably related to the video problem. A debian 4.3 kernel looks a long way off as it is only in Experimental at the moment. This is what inxi says about the graphics:
mike@lafite ~ $ inxi -G
Graphics: Card: Intel Device 1916

Ubuntu 15.10 with kernel 4.2 works great including lightning fast suspend/resume because Ubuntu backported some skylake support from 4.3 .

So for now I would stick to Ubuntu if I were you. You can go Ubuntu Mate for example.

Thanks freechelmi, that's useful to know. Might try the mate version until I get LMDE working. Does the screen scaling work ok? What setting do you use?

My Lafité II wouldn't suspend with Ubuntu 15.10 until I upgraded the kernel to 4.3. Now suspend works but it still won't come back after the screen blanks, so I've had to set it not to turn off the display.

I tried Ubuntu Mate live but the wifi was not supported so tried and installed Mint 17.3. Everything seems to be working since installing 4.2.0-19-generic #23~14.04.1-Ubuntu SMP, so that kernel may sort out your issues. I suspect 4.3 is not quite ready for production use yet?
