I haven't been able to make suspend/resume work on my MacBookPro10,1 since the jessie 3.16 kernel. I guess you are having better luck than me as it crashes on the resume - just when it switches to the resume'd kernel. I logged this bug on it https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=844788 I have been too scared to try my lightening ethernet adaptor with resume :-). I heard it always has to be present on boot up to be activated... Anyway for what it is worth you might be interested in this problem I found- I had to patch grub to "enable PCI bus mastering" on the graphics card to avoid a black screen. Still can't make resume work with Debian stretch kernel (I can run stretch on the old kernel fine though :-) As per NOTE: on top of https://wiki.debian.org/NvidiaGraphicsDrivers "...NOTE: For Apple systems, follow these steps first to prevent a black screen after installing the drivers: http://askubuntu.com/a/613573/134848"; * My notes are: Create grub script fragment file /etc/grub.d/01_enable_vga.conf containing literally cat << EOF setpci -s "00:01.0" 3e.b=8 setpci -s "01:00.0" 04.b=7 EOF Make it executable and install it into grub: sudo chmod 755 /etc/grub.d/01_enable_vga.conf sudo update-grub Reboot and check the values were set: setpci -s 00:01.0 3e.b setpci -s 01:00.0 04.b ______________________________________________ _______________________________________________ luv-main mailing list [email protected] https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
