Xorg 6.8 motif (mathematica) problem.

Silhouette · n00b Joined: 23 Aug 2002 Posts: 46

i recently changed over from xfree to xorg 6.8. everything went great. xcompmgr works, nvidia drivers work great and everything else works great. except for one kind of major thing. mathamatica doesn't work right. It displays everything fine, however when I use the scroll bar up it doesn't refresh the fonts right or something.

Here's a picture of what's happing: http://bitgoo.net/test/prob.png
I have tried adding the fonts, but to not much help. Here's the revelant parts of my xorg config and /etc/fonts/local.conf.

I also had some problems with mathematica after switching to xorg (missing libs and fonts).

I had to reemerge openmotif. openmotif compiled without problems, but for some reasons I don't know just installed the .a libraries not the .so's. I guess that's a specific problem of my installation, I solved it by installing the shared libraries by hand, after that mathematica started without problems.

Maybe that fixes your problem, too, since the screenshot looks like a problem in the GUI, which is motif-based in the case of mathematica.

Yhea,

I have been having some serious issues with Mathematica ever since I moved to Xorg. I am now recompiling openmotif like you were suggesting to see if it was the problem. I have been in contact with Wolfram and they have no idea why it is not working. So anyway, as far as Mathematica running slow, I will let you all know if this is the fix.....

Well, it did not work, I reemerged it and double checked to see if the motif was installed correctly. It looks as though it was. So, now I do not know what to do. My mathematica is still running slowly. Has any of you ever had this problem?

The funny thing is that reemerging openmotif helped in my case, although that's not logic. Of course Wolfram sells a static linked binary. But maybe something in xorg's configuration gets corrected by reemerging openmotif.

Anyway, at least my configuration works, so in the case reemerging openmotif doesn't help, we can compare configs.

Silhouette, did it work for you?

Well.

It did not work. I am not sure what configs I need to send to compare. I will include my XF86Config file, my font path enteries, and my XOrg.log file from the var directory.

I know this is long, but I just do not know what to include and what not to include. I am at witts end... Please help.

Oh and by the way, if you see anything else screewey, kindly let me know so that I might fix the system.

As far as the clues. The math command, or the kernel, looks as though it runs just fine. The GUI runs very slowly. When I resize the screen it draws slowly and it takes a long time for it to respond to typing and or focusing events.

Thanks in advance.

/etc/XF86Config ...

i just gave up on it. i went down to 6.7 to fix the problem. nothing is wrong now. although, no pretty drop shadows for me.

Not sure if this helps you guys at all?! After I changed to Xorg 6.8.0 I too had some issues with motif applications, and here is the related thread https://forums.gentoo.org/viewtopic.php?p=1579762.

Cheers,
Jens

Really what happens is a lot of sommunication with the Xserver. I ran strace on it and watched it when the cpu went to 100% utilization. That is the ticket. That is what is going on and why it is running slowly. I checked that other thread and all should be ok with my system as far as that thread goes. I was thinking that it was some kind of incompatability with mathematica and the installed version of motif.

It seems as though everything is statically linked.

Well...

I have been fighting this problem for some time now, should have been doing homework or something. Anyway, what I have found is that the problem is not related to glibc. It is deffinitly related to Xorg. I installed Xfree along side Xorg and glibc 2.2.5 along side my current version. Dangerous I know. Anyway, I tried each combination. When run in Xorg it fails to run right, but under both glibc versions it runs fine in XFree. So, I dont know what to say. I have no idea why it is so picky.

Looks like some more digging...

P.S. If anybody here is running xorg and mathematica and it runs can you send me your X config?

Hi!

At least I found out that mathematica doesn't work together with the new xorg composite extension. If I enable them mathematica looks for me like Silhouette's screenshot. As this extension is labeled experimental, and is currently of no use except for demonstrating that shadows and transparency is possible in X I simply turned it off in /etc/X11/xorg.conf.

Some other applications have problems with the composite extensions as well, for examples KDE's kuickshow.

Maybe you could also try to start Mathematica with

Thanks for that.

I will deffinitly be playing with this to see if I can get it to work.

What version of Xorg are you running?

prophecy · Tux's lil' helper Joined: 17 Nov 2003 Posts: 97

So, it now works. I do not really see the differences in your config vs my config but your works. Something subtle. I can not say thanks enough.

I upgraded yesterday to xorg 6.8.0-r2, still everything runs fine with the composite extensions disabled.

Could it be that the problems were caused by having both the "nvidia" driver and the "nv" driver in your config? I also don't see any significant differences except that (and the other resolution of course, whew 1920x1200 on a notebook, I'm impressed

)

Silhouette, could it be that you had the composite extensions enabled, when you had the problems under xorg? The mathematica window I got looked exactly like the one you posted in your first mail.

Seems strange that the couse would be both nv and nvidia defined. But no. Wait a min. I was doing some goofind around and the nv was added just before I gave up and tried your config. There is something fishy here.

I don't think you need both "nv" and "nvidia" in your /etc/X11/xorg.conf at the same time. If you have install nvidia-glx, then replace "nv" with "nvidia" and see what happens. Also, I thought you don't need the "DRI" section when you run nvidia!!!

yeah, i had composite enabled. that was probably it. is there any workaround yet (wolfram or other) that allows you to use composite and matematica?

BUMP.

I'm having a problem where if I try to plot anything remotely complicated, the cpu usage for X goes to 99% and stays there until I kill mathematica. I am using xorg 6.8.0-r3. In xfree it works, but since xfree has been removed from portage ( :roll:

), I would really like to get it working in xorg. Prophecy, is this similar to the kind of problems you were having before? Did you ever figure out what it was in your xorg.conf?

If it helps, I have an ati mobility radeon 9000. I don't have composite enabled.

If you are running xorg and your fonts doenst work and you tried everything else try uncommenting the following lines in xorg.conf
