Hi guys, I need to fix an issue that I have on my Debian Jessie 8.6 installation. I'm using a nVidia Optimus card and I already installed Bumblebee as per Debian Wiki[1] and Bumbleblee Project.
[1] - https://wiki.debian.org/Bumblebee [2] - https://github.com/Bumblebee-Project/Bumblebee/wiki/Troubleshooting You can see that I have 2 video cards: ederson@Inspiron-14R-5437:~$ lspci -vnn | grep '\''[030[02]\]' 00:02.0 VGA compatible controller [0300]: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16] (rev 09) (prog-if 00 [VGA controller]) 08:00.0 3D controller [0302]: NVIDIA Corporation GK107M [GeForce GT 750M] [10de:0fe4] (rev ff) (prog-if ff) ederson@Inspiron-14R-5437:~$ I am facing issues when I hibernate the computer. When I try to get it back again, I got a black screen and the CapLock _does not_ work. I was reaseaching on Debian Wiki [3] and I see there is a note about "Fixing corrupted video on resume" [3] - https://wiki.debian.org/Suspend "A very common issue found after the computer resumes is corrupted video (or black screen, or no LCD backlight). The first step is to check whether the system is still running, which can be simply done by pressing the Capslock button and check whether the Capslock LED is changing accordingly. If the system is still running, in most cases we need to add a video quirk for your video card. Debian now has kernel mode setting (KMS) enabled by default for most Intel, nVidia and ATI video cards. But pm-utils' video quirk does support KMS yet. So in most cases you should try disabling KMS first. The detail steps for your specific video card can be found on the KernelModesetting page. After disabled KMS, if the video after resume still corrupts, you can try to suspend the system by using some video quirks. Read the manpage of the pm-suspend program for a very detail explanation of all the quirks available, and try the combinations of them from commandline. If you successfully find one combination of quirks that works for your system, you can add them into /usr/lib/pm-utils/video-quirks to make them permanent. At the same time, please help to file a bug against the pm-utils package with a patch about your changes so it can benefit the mass. A common issue found on systems upgrading from old versions of Debian is the enabling of quirk-s3-bios freezes the system during suspend. If your system freezes during suspend, check the pm-suspend.log carefully after enabled debugging and make sure quirk-s3-bios is not used." There is a link on this topic and it goes to KernelModesetting page [4], but I was not able to set the configs on my machine and get hibernate option work as it should be.
