Description Kyle Agronick 2018-06-17 15:58:45 UTC

There are a bunch issues I've experienced with Optimus on SuSE. I think the experience is much harder than it should be and there are a number of pitfalls for getting it set up.

nvidia-xconfig purports to set up a good x config for optimus but it makes one that starts the x server in an infinite loop

I had to overwrite /usr/lib64/xorg/modules/extensions/libglx.so with /usr/lib64/xorg/modules/extensions/nvidia/nvidia-libglx.so to get bumblebee working.

I had to use intel-virtual-output after installing Bumblebee to just use my laptop's HDMI output. This isn't really a bug but I don't think users should have to edit config files, and run commands every time they want to use HDMI.

Desktop locked up after unplugging monitor. Restarting desktop manager make X restart over and over again.

I made a video of some of these issues:

Right. (open)SUSE never really supported Optimus systems. Users had mixed results
with Bumblebee/suse-prime packages found on the openSUSE build service. It's still recommended to enable only one of both GPUs in the BIOS - if possible. In your
case probably NVIDIA, if HDMI is connected to this GPU.

Please be aware that libglx meanwhile is handled via update-alternatives mechanism. When installing NVIDIA driver RPMs on an Optimus system XOrg's libglx
is chosen for to be on the safe side ...

I think its something that should definitely be looked at because every laptop I've gotten for myself or for work the past few years has had optimus. All the pieces are there. Its just a matter of detecting it and putting it in place for the user. Especially since they're putting different outputs on different chips, being able to use HDMI shouldn't be a power user feature.

I agree, if Suse wants to be a bigger player and make linux a better platform and not being replaced again by Windows this functionality should work out of the box.

Sorry but the optimus tech is in the disrepair state and there is nothing much to be done.
