LinuxQuestions.org - No direct rendering with Nvidia

No direct rendering with Nvidia

I am unable to get direct rendering to work with a Quadro FX 540 card and iH252 monitor. I use Ubuntu 12.04 and XFCE with lightdm.

I disabled my other monitor because I found something in a log file indicating that it was incapable of direct rendering, so I only have the one monitor to worry about.

I found this post about enabling DRI, but that didn't help.

I also added my user to the "use video devices" group, which I read was causing someone a problem, but that didn't help.

Here is my xorg.conf (generated by the nvidia tool, except for the dri stuff that I added):

I set the LIBGL_DEBUG environment variable, but there was no difference in output.

Also, just a note on my nvidia driver version, I was having serious problems with freezing because of video problems, so I downgraded the Nvidia drivers from the default 295.40 to 295.33, which seems to have solved that problem.

I would be grateful for any help!!

This suggests that you are using the Mesa GL library, not the nvidia one. What is the output of 'ldd /usr/bin/glxinfo'

Please post what exactly you have done to downgrade the driver (and also a reason why you have downgraded instead of upgrading to the latest version).

I was on the latest version, 295.40, because that is what Ubuntu packages, but I was having overflow problems that caused everything to freeze and forced a reboot. I'm sorry I don't have the link now, but I read that this was a known issue with that version of the proprietary drivers and it was recommended to downgrade to 295.33.

As for exactly what I did to downgrade...It wasn't a smooth process, even after 10 years of using Linux I still don't understand X or kernel modules well. I uninstalled the 295.40 drivers, then I had to blacklist nouveau and boot into text mode. From there I just ran the install script from Nvidia's site. (That makes it sound simple; in fact there were a lot of false starts and mistakes along the way.)

I'd remove your xorg, purge the nvidia drivers, then try the newer drivers. Probably 302.11 beta drivers from xorg-edgers rather than a manual install.

*blinks* Monitors dont do direct rendering, its the GPU. AFAIK the chip in the FX540 supports dual monitor direct rendering just fine...

The latest version is 295.53, so I would try that. Please also look for any errors during the build process and post them here.

I have a geforce 210 and my modules section looks like:

Code:

Section "Module"

    Load          "glx"

    Load          "extmod"

    Load          "record"

    Load          "dri2"

    Load          "dbe"

#Load  "dri"

EndSection

The nvidia driver setup program commented out the Load "dri" line.

Just for curiousity sake, what does the command

Code:

cat /var/log/Xorg.0.log|grep dri

return for you?

Right, see how it's linking against the libGL.so.1 in the mesa directory? What's the output of:

Code:

find /usr/lib/ -iname "libGL.so.1" -exec ls -latd {} \;

You guys are awesome! I upgraded to the 295.53 driver and direct rendering was immediately on. The output of glxgears was the same, but I can definitely tell a difference in rendering speed, not to mention less CPU usage.

In re the second monitor, it is entirely possible that I misunderstood something. I'm sure I read something like that -- and I had the same reaction, that I didn't think the monitor would make a difference -- but I probably didn't understand it properly. I turned it back on and it works fine.

In re the MESA GL drivers, I get the following output when running that command:

Code:

lrwxrwxrwx 1 root root 15 May 25 19:21 /usr/lib/libGL.so.1 -> libGL.so.295.53

Keep in mind that I had reinstalled the nvidia driver in the meantime, and in fact now that I check it, the client glx vendor string now says "NVIDIA Corporation". I did get an error during the build process: "unable to restore symbolic link /usr/lib/i386-linux-gnu/mesa/libGL.so.1 -> libGL.so.1.2 (File exists)" but I'm assuming that doesn't matter at this point.

Thank you so much for your help!
