Re: [Emc-users] Unable to get Nvidia Graphic Card working with nvidia drivers .

[alex chiosso]

Hi to all.
Just an update.
I set the isolcpu=1.
I disabled the legacy USB support from the BIOS .
I finally remove the Nvidia drivers + the NOUVEAU drivers and reboot the
system.
After that the latency numbers are pretty good (I mean comparing with the
previous numbers) .
The base thread peak is less than 18000 and the servo thread peak is less
than 22000 with :
- The internet browser opened and Youtube video playing ;
- 3 glxgears sessions opened ;
- Libreoffice Draw opened ;
- File manager opened and searching files and moving windows on the screen.
All this running for a couple of hours.
Anyway this is not the best but should be ok.

Thans a lot for the help and support you gave me. :-)

Alex

Thank you Kirk for your detailed explanation I will try your tips.
My cpu is an Intel dual core so isolcpu=1 should be the right one .

How many cores?  If two, the isolcpus=1 is correct; if four, or one or...
it may not be.

I modified Kent's "07_rtai" script to find the pae kernels; someone else
(sorry, names
are in the script) went through and worked out different cores and what
worked well.
IIRC his/her comments are in the wiki page and in the 07_rtai script.

Just something to check; John.

(Thinking more this may not affect boot problems, but anyway...)

I have a very limited understanding of this, but here is my take on it. 
I think many LinuxCNC video issues are due to OpenGL, which is used for 
the Gremlin backplot application.

OpenGL is supposed to be a more direct interface to the video hardware. 
It is a library of functions that allow talking to the video hardware to 
create shapes and shading. Unfortunately, the manufacturers control the 
hardware, and they don't usually like to share their ... well anything 
but your money. So, we have to live with their closed drivers that don't 
cater to Linux, or try dodgy reverse engineered open drivers, or bypass 
the issue.

For LinuxCNC there are two options for OpenGL. The common one is:

libgl1-mesa-glx

which is an API that talks to video hardware (BTW it's a different 
Mesa). The other is:

libgl1-mesa-swx11

which is a software only version that doesn't talk to video hardware and 
is also much slower. One can try running GLXgears and if it crashes, 
switch to the swx11 version. To see which version is active, open 
Synaptic, type "libgl1" into the Quick Search box, and see which libgl1 
from above has the green box next to it. If you decide to change your 
active libgl1, Mark the inactive version and Apply. You should get a 
message indicating that some files will be uninstalled. This is because 
each version is mutually exclusive. Make note of the files you unloaded 
in case you have trouble putting things back the way they where.

Hopefully, someone that knows better will correct any above misinformation.

Re: [Emc-users] Unable to get Nvidia Graphic Card working with nvidia drivers .

[alex chiosso]

Thank you Eric.
Your observation may be correct .
The Nvidia driver installation is a big issue for many users that are not
using LCNC .
I will remove the drivers I've installed and I will go for the Vesa
solution.
The Gigabyte and ASRock mobo seems to be better than ASUS for LCNC.
And to have a separate graphic card it's not a solution anyway.
My BIOS do not have much parameters to be setup specifically to get a
better performance for real time .
I've made the isolcpu=1 modification but numbers are always pretty high
(6-65000 on both threads) but more stable as I can see.

Re: [Emc-users] Unable to get Nvidia Graphic Card working with nvidia drivers .

[Eric Keller]

Vesa worked fine.  The open source Nvidia drivers were not good for
latency.  You may wish to go with an interface that doesn't use 3d.  I
believe that the problem with the Nvidia system is that they want a
specific kernel layout and it doesn't work with the RTAI kernel, but I
can't be sure

Re: [Emc-users] Unable to get Nvidia Graphic Card working with nvidia drivers .

[alex chiosso]

Hi Eric .
Did you get good latency numbers with Vesa drivers.
My need is to get the best latency numbers is possible.
If it's better to use the Vesa drivers I will do that .
Nowadays the two biggest Graphic cards/chips manufacturers seems to be
Nvidia and ATI so why it is so hard to get this cards work with their
proprietary drivers ?
Maybe it is a stupid question but I remember that somewhere in the LCNC
documentation there is also the suggestion to use a graphic card instead of
a mother board integrated one. :- (
I used a ASUS mobo with a ASUS GPU thinking about a proper solution but
maybe I was wrong .

Re: [Emc-users] Unable to get Nvidia Graphic Card working with nvidia drivers .

[Eric Keller]

Last time I set up a lcnc system I had a lot of trouble with the Nvidia
drivers -- they wouldn't install.  I did go with Vesa.  I don't really
think it's a problem.

Re: [Emc-users] Unable to get Nvidia Graphic Card working with nvidia drivers .

[alex chiosso]

Hi Dave .
Actually seems that the NOUVEAU drivers are used as I can see into the
Xorg.0.log file I've attached .
Do you suggest to use the Vesa instead of Nouveau ?

Nvidia is a known problem see
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TroubleShooting#NVidia_and_ATI_graphics_cards
try those solutions and any other graphics card you have lying around

[Emc-users] Unable to get Nvidia Graphic Card working with nvidia drivers .

[alex chiosso]

Hi to all.
I've built a new desktop pc (honestly I bought the hw components a couple
of years ago) to use it for LCNC application hoping to get a good latency
numbers .
The mother board is an ASUS P5KPL SE ;
The Graphic Card is an ASUS EN8400GS 512MB based on the GeForce 8400GS chip
;
The Processor is an Intel Pentium E6500 Dual Core ;
The Ram is a 2GB DDR2 800Mhz ;
The HD is a Seagate Barracuda 7200.12 ;

I've installed LCNC using the pre-compiled version CD 2.6.1 with Debian
Wheezy .

After the installation done and the upgrade using the update manager I ran
the Latency test application to see the latency numbers and the test was
not good (I mean about 7 Max Jitter on both the threads) .

I've not modified the GRUB for ISOLCPU=1 yet .

But what I can see is that the Nvidia Card is not using the proprietary
drivers .

I tried few different ways using "solutions" from the net but there is no
way to get the Nviadia drivers to be loaded properly.

I post the files :
- Xorg.0.log.old that show some information on the Nvidia drivers loading
issue ;
- Xorg.0.log that show the information after a correct startup of the PC
without invoking the use of the Nvidia proprietary Drivers.

The last test I did was reinstalling the LCNC CD (so a clean of all the
Nvidia trials tests I did) and try this solution
 from the Official
Debian Wiki site .

The problem is that with the invoking of the Nvidia Drivers load procedure
I can't get the system booting completely and the display is showing a
blinking cursor.

Maybe the system stops when is loading (or trying to load) the Nvidia
Drivers .

The only way-out that I found is to remove (or rename) the file

/etc/X11/xorg.conf.d

and perform a system reboot.

As it's clear I'm not familiar with Linux to be able to solve this
issue so I'm asking your help.
