Description Rémi Verschelde 2015-06-28 21:17:14 CEST
+++ This bug was initially created as a clone of Bug 15734 comment 39 +++

I tried to install Mageia 5 on my new laptop (UEFI) an ASUS N551J with two graphical cards (intel and nvidia). I have tried every option mentioned in the errata (hybrid graphics). I have tried the Live KDE 64 DVD and the classical 64 DVD. Nothing works. I am now 'doomed' to use Mint, that works at once, but I like Mageia much better (if it is installable).


Sometimes at boottime (LiveDVD) I get many nouveau errors and after a while I get a KDE desktop (intel detected?). I can than install it and after reboot I sometimes can configure a user and can log in into KDE. After a few seconds everything freezes. Poweroff and poweron and than it freezes already at boottime (blank screen or with nouveau errors with sometimes I see kernel panic).

Sometimes at boottime (LiveDVD) I get less nouveau errors and it freezes already (no KDE).

I tried boot options as suggested 'optimus' and/or 'rd.blacklist=nouveau rd.blacklist=nvidia xdriver=intel' â> No effect. Still nouveau errors at boottime and/or freezes.


Installation works until after reboot. Same problems as with the LiveDVD.
I tried the boot options, no effect. At the point of the installer to configure the graphics, it suggested 'Intel 810 and later' and not 'use intel only' as told in the errata. Even with Intel selected I get nouveau errors at boottime, with or without boot options.

It seems a problem like mentioned in the errata with the hybrid graphics (Intel+Nvidia), but the suggested options does not work.

Linux Mint 17.1:

No problem, works at once. No errors.

Same issues on my new laptop:

4th Gen Core Processor Integrated Graphics Controller
GeForce GTX 850M

Went back to Mageia 4, no issues there, as there never were.

Comment 3 Martin Whitaker 2015-06-28 23:08:01 CEST
A quick search found this:


My recollection is that using rd.blacklist didn't work for me, because the nouveau driver got loaded later in the boot sequence. You could try adding

  blacklist nouveau

to /etc/modprobe.conf on the installed system to see if that helps.

I see in Peter's log that he is also experiencing bug 16033, although that is probably not important at this stage.
Comment 4 Martin Whitaker 2015-06-28 23:58:49 CEST
Just done some experiments on my laptop, and I need both the boot option *and* the entry in /etc/modprobe.conf to prevent the nouveau module being loaded.

Furthermore, the required boot option is "rdblacklist=nouveau", not "rd.blacklist=nouveau".

Comment 5 Peter Woldering 2015-06-29 22:08:07 CEST
It is working now :-)

I use the boot options 'rdblacklist=nouveau nouveau.runpm=0 xdriver=intel'

nouveau.runpm=0 is a tip from doktor500, with this the LiveDVD/USB gives nouveau errors but I get at least at every boot a KDE desktop.

The same boot options I use for the installed system.
Right after install with the first boot I selected 'Safe Mode' and added 'blacklist nouveau' to /etc/modprobe.conf.

After this I get no errors and get a beautiful Mageia KDE desktop.

Thanks for all the help.

Comment 6 isadora 2015-07-04 16:38:20 CEST
Same here.
Installed Mageia 5 in a free partition, so i could leave Mageia 4 in place, in case of.

But, so far the abovementioned workaround worked.

I have the model from Asus called N550JK and I have the exact same problem.

My fix was to add blacklist=nouveau the kernel boot line.

Is there an ETA on this fix?

Before the release of Mageia 6?

Comment 12 Sébastien GUERIN 2018-02-16 14:09:43 CET
Same problem for me.
Adding kernel option nouveau.runpm=0 worked for me (seen here : https://bugzilla.redhat.com/show_bug.cgi?id=1525213)
Comment 13 Sébastien GUERIN 2018-03-19 15:36:22 CET
This bug is also discussed on launchpad:

They recommand kernel option nouveau.modeset=0.
It also works.
Comment 14 Sébastien GUERIN 2018-03-20 18:57:42 CET
Also discussed at bumblebee:

They recommand kernel option acpi_rev_override=5.
It also works... Don't know which option is the best.
