can't open after fixing smi issues

I did what the fixing smi issues page told me to, and while my latency issues are now fixed, emc2 does not open anymore. any ideas?
the formatting on this may be a little odd...it had to go through a lot to get here. my cnc computer stays away from things like the internet...

It looks like something is wrong with your libXrender library. This is where things went south for you:

X Error of failed request: BadLength (poly request too large or internal Xlib length error)

Searching for the string "poly request too large or internal Xlib length error" turns up this:

www.nvnews.net/vbulletin/showthread.php?t=168919

which leads here:

bugs.freedesktop.org/show_bug.cgi?id=9526

Then again you can't believe everything you read on the web. Until you get things to work who knows? But it is where I'd focus.

Yours is going to be different than mine but similar because I don't run Ubuntu but I know how it works a little

locate libXrender.so
/usr/lib/libXrender.so
/usr/lib/libXrender.so.1
/usr/lib/libXrender.so.1.3.0

dlocate -S /usr/lib/libXrender.so.1.3.0
libxrender1: /usr/lib/libXrender.so.1.3.0

dpkg --status libxrender1

apt-get update

apt-get install libxrender1

Or run a program called synaptic and it may tell you a bit more about what you're about to do.

I know everyone around here says don't upgrade anything but sometimes maybe you have to break the rules a little? As always before doing anything drastic try to get a second opinion. But it already doesn't work now and what I suggest shouldn't hurt it that much more. Good luck!

I did what the fixing smi issues page told me to, and while my latency issues are now fixed,

Have you tried to undo the changes you made and test again?

Hi

From the errors, sounds like pfred1 should be on the right track.
It is very strange that the SMI fix should give rise to this however, presuming that you have opened Axis without problem previously.

If you comment out loading the SMI module, does everything load without error again?

One thing that occurs from the error messages, is to try changing the line
DISPLAY=axis
in your INI file to
DISPLAY=tkemc (or xemc)
just to see if the calls initiating this error are GL related

I have spent a bit of time with the SMI module and trying to get it to work on other Intel chipsets recently.
(www.linuxcnc.org/index.php/english/compo...=18&id=18365&limit=6)

Could you do a lspci -vv from a terminal and post the print please.
I would be very interested in exactly which version of the Intel 82801 or ICH* chipset you have, in case this sort of problem comes up again.

regards

I've read a bit more about SMI and ran across some information that may or may not apply here. Apparently Intel didn't simply invent SMI just to drive us nuts. In some cases SMI actually serves a purpose, and this might be one of those rare cases. Which leads me to think that changing the video adapter might make this not one of those cases.

Sometimes it is a lot easier to plug in a video card than it is to mess around with loads of software, if you happen to have one kicking around.

Although there is no guarantee that will help any, and that might not be the end of it either. The cure might be a combination of software and hardware remedies. There are a lot of interactions going on that have to mesh in order for things to just work.

Other software to look at is X Window itself, version, and drivers it is using. The kernel has its fingers in the video system too. There aren't any guarantees anything will work though. But I still see a few avenues to pursue before declaring this cause lost.

OKAY. i'm back. it really sucks when you have to go to school and don't have enough space for your cnc machine so you have to take a two-month-long break from fixing it...

i don't have another video card lying around, sadly enough, otherwise i would give that a shot.

i tried commenting out the changes i made, to no avail. i'm also running into the issue that i can't run updates on that computer because it has no internet connection... it seems i chose to buy a wireless adapter that doesn't get along well with 10.04. which is too bad, it worked flawlessly on this computer with 11.10. but it seems that i need internet to download the things needed to get my adapter to work, and even then they don't always work...

honestly i think it might be easiest for me to just start again from scratch...i don't have much on it, and nothing important. i got it to work before, back when i was dualbooting with xp. it should work again, just without xp, if i just do a clean reformat and reinstall... but that'll be my last resort plan. i'll try everything i feel is within my capabilities first.

oh yeah, and i wasn't quite sure what i was supposed to be looking for with the display=tkemc/xemc change, but i tried them both and emc still refused to open. i have the errors that showed up if you want them but i'm pretty sure they're the same except with the display= changed.

okay this is really weird but i looked again at the errors i was getting when i switched to display=tkemc and display=tkxemc just to be sure they were the same errors i posted originally...they're not. so i went back downstairs to look at it again...tried to open emc...yep, i'm not getting the "X Error of failed request: BadLength (poly request too large or internal Xlib length error)" anymore, now it's something that seems a lot more directly related to my messing around with rtai modules. i added the smi module to rtapi.conf again and retried, and this is the error i got.

It took some doing but I've my garage hard wired for Internet access. Linux is as you're finding out much less fun disconnected. I've had spotty results with wi-fi. No one comes right out and says it but Internet connectivity is almost a prerequisite for getting this stuff to work. Technically you don't need it, but it is an awful lot more work going that route. Isn't this stuff already hard enough?

Hi

Rather difficult to assist because you have posted the errors but not the files which caused them.

2 things could be causing

/etc/emc2/rtapi.conf: line 21: : command not found

which appears to be the root of your errors

One is that you haven't edited the rtapi.conf as per wiki.linuxcnc.org/cgi-bin/wiki.pl?FixingSMIIssues

Most common mistake omitting the smi module from either MODULES or MODPATH lines.
Or just could be a mis-spelling or typo somewhere, or using a Windoze editor and filling the file with CR/LF pairs etc

The other could simply be that linuxcnc exited last in an error state and did not properly unload rtai
Trying to re-start it without a re-boot will produce all sorts of strange rt module errors, because some of them are still loaded.

If neither of above, you will need to post a zip of your rtapi.conf, .ini .hal files etc so we can look at them.

Your chipset ICH7_01 is one specified in the smi module, so should work OK.
Would however appear prudent to get your system back working, albeit with SMI spikes, and go from there initially.

regards
