How did you install the nvidia drivers? The ones packaged by Mageia, or the ones provided by nvidia?

Comment 4 Christian C 2016-09-27 15:59:06 CEST

I used drakconf that propose to install the Mageia nvidia packages.
See /var/log/messages in attachment 8448 [details] https://bugs.mageia.org/attachment.cgi?id=8448

Thierry, it looks like the drakx code to prefer prebuilt kmods now bites us since we dont have prebuilt proprietary drivers anymore...

From the log:
drakx11[24329]: those kernel module packages can be installed: dkms-nvidia340 nvidia340-kernel-3.19.8-desktop-3.mga5 dkms-nvidia340 dkms-nvidia340 nvidia340-kernel-4.1.12-desktop-1.mga5 nvidia340-kernel-4.1.13-desktop-2.mga5 dkms-nvidia340 dkms-nvidia340 dkms-nvidia340 nvidia340-kernel-4.1.12-desktop-1.mga5 nvidia340-kernel-4.1.13-desktop-2.mga5 dkms-nvidia340 


Then it goes ahead and pulls in / "downgrades to ancient release kernel" with matching kmods:
[RPM][24353]: install kernel-desktop-3.19.8-3.mga5-1-1.mga5.x86_64: success
[RPM][24353]: install nvidia340-kernel-3.19.8-desktop-3.mga5-340.76-27.mga5.nonfree.x86_64: success


even if the user had newer kernels:
bootloader-config[24455]: current labels: linux-nonfb failsafe desktop 4.1.12-1.mga5 desktop 4.1.13-2.mga5 linux desktop 4.4.13-1.mga5 desktop 4.4.16-1.mga5


and poof...

So regardless of whether drakx got fixed, this cannot happen in Mageia 6 or later.

Mageia 5 has officially reached its End of Life on December 31st, 2017 https://blog.mageia.org/en/2017/11/07/mageia-5-eol-postponed/
It only continued to get important security updates since then, but non-security bugs have no chance of still getting fixed.

Closing as OLD
