42.2 and Optimus Technology

English Hardware
1

Hi,

Have installed 42.2 and wanted to put my intel/nvidia card with optimus technology working only with nvidia gpu all the time and switch it to intel in nvidia settings like i was able to do on Mint. Is it also possible on 42.2?

I only have Primus and bumblebee installed but intel and nvidia drivers are not installed yet. Don’t want to crash the whole system.

Any suggestions/help?

Thanks

Bumblebee will only allow to run selected applications on nvidia though, the desktop will still run on the intel chip (unless you hack some system files…).

You might want to have a look at prime too:

And you don’t have to install an intel driver, that’s there by default anyway… :wink:

Unfortunately, contrary to 42.1, prime is not yet working with 42.2 and KDE, at least on my Optimus laptop.

I have tried Knurpht’s suse-prime repository for 42.2
and get greeter errors when trying to logout then in order to switch to prime-selected Nvidia graphics.

With the suse-prime-alt version of Tumbleweed, which now has disappeared from the repositories, I could log out of KDE after ‘prime-select nvidia’,
but the X-server won’t start.
In dmesg I then find an error:

Qt bearer thread [18243] : segfault at 9 ip ....... error 4 in libQt5DBus.so.5.6.1

kopstukken had tried prime with Leap 42.2 RC1 and KDE without success, as he described here,
but when he changed to Gnome, everything seemed to work fine.

With bbswitch installed I am able to switch off the Nvidia card to reduce power consumption when using Intel graphics.
