Bug #650
closedmatlab Xvfb error
0%
Description
pyace.py crashes on my machine. In order to get it to work, I have to disable the " co" option in apParam.py. Lines 482... become:
if os.path.isfile(rgbfile+".txt"):for rgbfile in filelist:
#hacked out -co option to xvfb
return " "
I only edited locally and have not committed. Moreover, I have had to hack all programs that require Xvfb on my machine. I am using Ubuntu version 9.10.

It is different on every distribution, I added code to check between Fedora and CentOS. See if you can add an automatic check to make it work.

I don't really know what the different options are trying to do. Below is the output from xvfb.log. Can you tell me what I should be trying?
Xvfb :2202 -once -ac -pn -screen 0 1200x1200x24 -fp /usr/share/fonts/X11/misc -co /usr/share/X11/rgb &Unrecognized option: -co Fatal server error: Unrecognized option: -co

The options do not matter so much except that on CentOS the rgbfile option is required or it crashes and on Fedora if the rgbfile option is provided it crashes. I do not know why, but I know this is the case, so we have a work around using the getXversion option.
It looks like the rgbfile may not be required anymore on CentOS and we can comment it out. I will test it and get back to you.

Okay, Scott here's how it should work.
The older version of the Xvfb command need a link to the rgbfile, so it can map the color white to '#ffffff', otherwise it has no clue what white is.
I included the the getXversion function to determine which version of X you are running and add the command or not depending on the version.
CentOS v5.2-v5.5 with X v1.1.1 and Fedora v7,v8 requires the rgb file
Fedora v9-v13 with X v1.8 does not have rgb file option
Can you send me the info you get from the command:
X -version
You will need to copy the apParam.py from the trunk to your branch checkout to test.

Your change to apParam.py didn't work for me. Below is the output from X -version:

Before reporting problems, check http://wiki.x.org
to make sure that you have the latest version.
BTW, when I tried to run pyace.py from the trunk, it failed with a completely different error. Is the trunk version running now?

I made another change and this one should work with your version of X. Also, now by default it assumes a new version of X.

That did it. It works now. Should I change status to closed now?

Next step is code review. Since you've tested it, it can be closed after the review.
