No video graphics accelaration on Intel / Nvidia GT410M

[venks]

Hi,
I just upgraded my laptop (Fujitsu Lifebook 531) from 13.04 to 13.10. The upgrade went rather fine but after that I cannot have my desktop effect running. I found out that the glx modules are not loading for intel graphics. I am not so bothered about using the nvidia graphics at the moment since I don't really play games.

The graphic acceleration was working previously with 13.04 but not any more. Here are some of the interesting stuff from /var/log/Xorg.0.log:

(II) "glx" will be loaded by default.
[   895.166] (WW) "xmir" is not to be loaded by default. Skipping.

So what should I do to make it work again. Any and all help are greatly appreciated.

What do you have for the "Composite" setting on the Advanced tab of the "Desktop Effects" option of System Settings.
Mine shows, under gl: 3.1, 2.0, 1.2 and xrender, and defaults to 2.0. I get vsync rates for Hires.
Try each of the ones your's shows.

Hi GreyGeek,
I have tried all those combination and it doesn't work. So as a test, I ran glxinfo in a terminal and this is what I got:

name of display: :0
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Error: couldn't find RGB GLX visual or fbconfig
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Error: couldn't find RGB GLX visual or fbconfig

Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".

So that gave me the clue, that glx or the 3D acceleration module is not loaded.

If you need more info, I would be happy to provide.

I took a better look at your OP and noticed this:

Module glx: vendor="NVIDIA Corporation"
[ 895.185] compiled for 4.0.2, module version = 1.0.0
[ 895.185] Module class: X.Org Server Extension
[ 895.185] (II) NVIDIA GLX Module 319.60 Wed Sep 25 14:24:11 PDT 201

The nouveau driver should be loaded. You can check by using a Konsole to do
lsmod | grep nouveau

Even if you blacklist nouveau in /etc/defaults/blacklist.conf and go so far as to remove the xserver-xorg-video-nouveau package the nouveau driver will be used because it is built into the kernel. Things would be easiest if you could open the BIOS and disable the Intel driver and enable the NVidia one. If you can't do that then check this post: http://www.kubuntuforums.net/showthr...l=1#post337627

Hi GreyGeek,
thanks for you input, I got it solved. The nouveau driver was not loaded (lsmod did not show a nouveau driver) but nvidia driver was loaded. So I used Muon package manager to remove them completely from the system. After that I restarted and now I can have my desktop acceleration (UI effects). But now I have another problem - my laptop seems to think that its attached to an external display so I get a wider desktop even there is none. I guess thats for another thread.

Use the "Display and Monitor" option in System Settings to adjust your monitor size and default output.
