I'm experiencing the same issue. When using kernel 3.17 everything's fine but with kernel 3.18 or 3.19 the screen goes black intermittently but pretty often.
If I change the brightness of my screen I can see the black goes a bit brighter if that makes sense. Sometimes I can press the sleep button and it goes to sleep. However when it comes back it goes into the black screen soon enough and most of the time the sleep button doesn't react anymore. One other thing I managed to nailed down is when I used a secondary monitor instead of my laptop one, nothing goes wrong. Hope this helps.

At least I could solve this. Since that time it occurs from time to time, that the screen freezes no matter which application I am just running. The only way out is to press the power bottom and to restart the computer. ubuntu-bug linux shows: ProblemType: Bug ApportVersion: 2.14.1-0ubuntu3.12 Architecture: amd64 CurrentDesktop: X-Cinnamon Date: Fri Aug 28 12:07:10 2015 Dependencies: adduser 3.113+nmu3ubuntu3 apt-utils 1.0.1ubuntu2.10 base-passwd 3.5.33 busybox-initramfs 1:1.21.0-1ubuntu1 coreutils 8.21-1ubuntu5.1 cpio 2.11+dfsg-1ubuntu1.1 dbus 1.6.18-0ubuntu4.3 debconf 1.5.51ubuntu2 debconf-i18n 1.5.51ubuntu2 debianutils 4.4 dmsetup 2:1.02.77-6ubuntu2 dpkg 1.17.5ubuntu5.4 [modified: sbin/start-stop-daemon] e2fslibs 1.42.9-3ubuntu1.2 e2fsprogs 1.42.9-3ubuntu1.2 findutils 4.4.2-7 gcc-4.8-base 4.8.4-2ubuntu1~14.04 gcc-4.9-base 4.9.1-0ubuntu1 gettext-base 0.18.3.1-1ubuntu3 grub-common 2.02~beta2-9ubuntu1.3 grub-gfxpayload-lists 0.6 grub-pc 2.02~beta2-9ubuntu1.3 grub-pc-bin 2.02~beta2-9ubuntu1.3 grub2-common 2.02~beta2-9ubuntu1.3 ifupdown 0.7.47.2ubuntu4.1 initramfs-tools 0.103ubuntu4.2 initramfs-tools-bin 0.103ubuntu4.2 initscripts 2.88dsf-41ubuntu6.2 insserv 1.14.0-5ubuntu2 iproute2 3.12.0-2ubuntu1 isc-dhcp-client 4.2.4-7ubuntu12.3 isc-dhcp-common 4.2.4-7ubuntu12.3 klibc-utils 2.0.3-0ubuntu1 kmod 15-0ubuntu6 libacl1 2.2.52-1 libapparmor1 2.8.95~2430-0ubuntu5.3 libapt-inst1.5 1.0.1ubuntu2.10 libapt-pkg4.12 1.0.1ubuntu2.10 libasprintf0c2 0.18.3.1-1ubuntu3 libattr1 1:2.4.47-1ubuntu1 libaudit-common 1:2.3.2-2ubuntu1 libaudit1 1:2.3.2-2ubuntu1 libblkid1 2.20.1-5.1ubuntu20.6 libbz2-1.0 1.0.6-5 libc6 2.19-0ubuntu6.6 libcap2 1:2.24-0ubuntu2 libcgmanager0 0.24-0ubuntu7.3 libcomerr2 1.42.9-3ubuntu1.2 libdb5.3 5.3.28-3ubuntu3 libdbus-1-3 1.6.18-0ubuntu4.3 libdebconfclient0 0.187ubuntu1 libdevmapper1.02.1 2:1.02.77-6ubuntu2 libdrm2 2.4.60-2~ubuntu14.04.1 libexpat1 2.1.0-4ubuntu1 libfreetype6 2.5.2-1ubuntu2.4 libfuse2 2.9.2-4ubuntu4.14.04.1 libgcc1 1:4.9.1-0ubuntu1 libgpm2 1.20.4-6.1 libjson-c2 0.11-3ubuntu1.2 libjson0 0.11-3ubuntu1.2 libklibc 2.0.3-0ubuntu1 libkmod2 15-0ubuntu6 liblocale-gettext-perl 1.05-7build3 liblzma5 5.1.1alpha+20120614-2ubuntu2 libmount1 2.20.1-5.1ubuntu20.6 libncurses5 5.9+20140118-1ubuntu1 libncursesw5 5.9+20140118-1ubuntu1 libnih-dbus1 1.0.3-4ubuntu25 libnih1 1.0.3-4ubuntu25 libpam-modules 1.1.8-1ubuntu2 libpam-modules-bin 1.1.8-1ubuntu2 libpam-runtime 1.1.8-1ubuntu2 libpam-systemd 204-5ubuntu20.13 libpam0g 1.1.8-1ubuntu2 libpcre3 1:8.31-2ubuntu2.1 libplymouth2 0.8.8-0ubuntu17.1 libpng12-0 1.2.50-1ubuntu2 libprocps3 1:3.3.9-1ubuntu2.2 libselinux1 2.2.2-1ubuntu0.1 libsemanage-common 2.2-1 libsemanage1 2.2-1 libsepol1 2.2-1ubuntu0.1 libslang2 2.2.4-15ubuntu1 libss2 1.42.9-3ubuntu1.2 libstdc++6 4.8.4-2ubuntu1~14.04 libsystemd-daemon0 204-5ubuntu20.13 libsystemd-login0 204-5ubuntu20.13 libtext-charwidth-perl 0.04-7build3 libtext-iconv-perl 1.7-5build2 libtext-wrapi18n-perl 0.06-7 libtinfo5 5.9+20140118-1ubuntu1 libudev1 204-5ubuntu20.13 libustr-1.0-1 1.0.4-3ubuntu2 libuuid1 2.20.1-5.1ubuntu20.6 libxtables10 1.4.21-1ubuntu1 lsb-base 4.1+Debian11ubuntu6mint1 [origin: linuxmint] makedev 2.3.1-93ubuntu1 module-init-tools 15-0ubuntu6 mount 2.20.1-5.1ubuntu20.6 mountall 2.53 multiarch-support 2.19-0ubuntu6.6 netbase 5.2 os-prober 1.63ubuntu1 passwd 1:4.1.5.1-1ubuntu9.1 perl-base 5.18.2-2ubuntu1 plymouth 0.8.8-0ubuntu17.1 plymouth-theme-ubuntu-text 0.8.8-0ubuntu17.1 procps 1:3.3.9-1ubuntu2.2 psmisc 22.20-1ubuntu2 sensible-utils 0.0.9 systemd-services 204-5ubuntu20.13 sysv-rc 2.88dsf-41ubuntu6.2 sysvinit-utils 2.88dsf-41ubuntu6.2 tar 1.27.1-1 tzdata 2015f-0ubuntu0.14.04 ucf 3.0027+nmu1 udev 204-5ubuntu20.13 upstart 1.12.1-0ubuntu4.2 util-linux 2.20.1-5.1ubuntu20.6 uuid-runtime 2.20.1-5.1ubuntu20.6 zlib1g 1:1.2.8.dfsg-1ubuntu1 DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2015-06-21 (67 days ago) InstallationMedia: Linux Mint 17.2 "Rafaela" -
