[K]Ubuntu on the Asus N73SV video issues – i915, Nouveau, Nvidia and Bumblebee

Well, after a month on using this Asus Laptop N73SV there are some issues with it.

The first one, and I’m not sure if it’s a driver issue or just a plain hardware issue is that the external connected monitor was working fine, and then started to have a blue tint and now it has a green tint. So first I wonder if the VGA cable or the monitor itself was bad, but replacing it by another same monitor brand and model  and different VGA cable, it has shown the same issues. So Ok, it’s a laptop issue that some HP owners are also having… Just search for HP an video tint… Removing the battery and power, waiting some time, and booting up with the external monitor, even the ASUS logo is tinted… So it’s not a K/Ubuntu issue. Solution? None so far. I have to try with a different monitor/and cable namely HDMI.

The second part of this post related with the video issues that I have is due to the fact that this N73SV has dual cards: an Intel i915 and NVidia GT540M. While trying to debug the above issue, I ended up with no desktop effects on KDE KDM by messing around with the desktop effects options… Whatever I did to enable them I was also greeted with the message that Effects couldn’t be enabled. So issue was related to the fact that the GLX libraries couldn’t be found/loaded… When running glxgears this error appear:

name of display: :0.0
Xlib: extension “GLX” missing on display “:0.0”.
Xlib: extension “GLX” missing on display “:0.0”.

The solution:
I’ve removed bumblebee and nvidia, which cleared the issue:

apt-get purge bumblebee
sudo apt-get purge nvidia*
apt-get install –reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
dpkg-reconfigure xserver-xorg
reboot

And after this I could enable  again Desktop effects but I was using the default Intel driver and the Nouveau driver.

Finally, I’ve installed again MrMee/Bumblebee, which by itself installed again the Nvidia drivers, and after that I could only boot into Recovery Mode, because a normal start wouldn’t give me the Kubuntu boot logo and at final boot stage I just had a black screen with an hanged computer…

This issue is due to the fact that the nouveau driver is/was enabled, and I had to disable it. I found no complete instructions for doing that, but these do work:

The nouveau driver needs to be disabled, by editing two files:

/etc/modprobe.d/blacklist.conf

Add at the end of this file the following line: blacklist nouveau

And then, the other file to edit it depends of your grub version. For Grub2 , there is the need to add the following to the file /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pci=nomsi nouveau.blacklist=1

And then run the command: update-grub2

On Grub1, just edit the menu.lst file and add the nouveau.blacklist=1 to yur booting kernel options, keeping in mind that after a kernel upgrade you need to blacklist the module again.

Booting up now with the Intel Driver and the Nvidia driver installed by Bumblebee should work.

  1. Dear friend,

    I also bought the N73sv, a great computer to work, super specs, a real desktop replacement. Few months ago I decided to leave Microsoft Windows behind and embrace the linux culture, of course I’m having a hard time getting it all together, but I cannot imagine myself going back.

    With the N73sv the installation process was rather complicated, pretty difficult to make it work, and most of the good things on this painful path happened thanks to you and your blog. I got the basic stuff working reading your “tutorials” and following your leads.

    I suppose I’m the regular visitor to your site, someone looking for answers, usually finding them, but with a passive approach to a pure and simple “thank you”… this time I decided to make a full stop and thank you, thank you for sharing your knowledge about ubuntu/linux on this great computer.

    I’m looking forward to follow your new leads and see if I can get the nvidia card working this time.

    best regards

    vasco
