Linux Mint 18 suspend issue
linux mint;suspend
I've solved this issue by installing new linux kernel 4.5.2-040502-generic following this guidelines:https://askubuntu.com/questions/761758/ubuntu-16-04-lts-cannot-suspend-fails-on-suspendinghttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574125/comments/26Install new kernel (4.5.2):cd /tmpwget \kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.2-wily/linux-headers-4.5.2-040502_4.5.2-040502.201604200335_all.deb \kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.2-wily/linux-headers-4.5.2-040502-generic_4.5.2-040502.201604200335_amd64.deb \kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.2-wily/linux-image-4.5.2-040502-generic_4.5.2-040502.201604200335_amd64.debsudo dpkg -i linux-headers-4.5*.deb linux-image-4.5*.debReboot your system and try if suspend works.In case something goes wrong with new kernel (4.5.2) reboot your computer and select Advanced options for Linux Mint 18 Cinnamon 64-bit in boot menu, then select your old kernel (4.4.0-21).
