[Fwd: Re: Java crashes X server]

[Hans D. <han...@we...>]

Hi!

I just tested my freshly compiled X server, and now java suddenly works 
without a hitch on both X server.
I compiled using the latest gentoo 4.3.0-r5 sources with all the normal 
gentoo patches + your prefbusid3 patch.

Well.. now it works, but I don't really know why.. The fresh compile 
might have done it, or maybe one of the gentoo
patches for the XServer might have done it.

I still experience the second bug I described in my previous mail (kde 
desktop1 dying when killing the other X server), so the
bugs were obviously not connected.

Hi!

Good to know I'm not on my own ;)
What I have done so far:

1. I have tried to use a different jdk (sun-jdk1.4.2 and 
blackdown-1.4.1) both have the same problem.
2. I have tried a different X server binary that Svetoslav Slavtchev 
made available to me. This one was specifically
compiled on Gentoo, but it still didn't change a thing.
3. I have also compiled my own X server with your prefbusid3 patch, but 
I haven't tested it yet. I doubt it will change anything.

What I still can tell you from memory is this:

I used kernel 2.6.0 and I also 2.6.1 without ruby, and with only one 
Xserver, and java worked fine. I got started
playing with ruby, and got it working at kernel 2.6.2, and I already 
then had the java crashes.

There is also one more bug that might have something to do with this:
- My primary card is an Ati Radeon 9800Pro AGP. I use it in a dual-head 
setup (no xinerama). I have a KDE desktop on each monitor.
- My secondary card is is an Ati Radeon 7500 all-in-wonder PCI, I run 
Gnome on my Television with it.
The bug is, that whenever I log out of my gnome session on the tv, my 
Primary Monitor (kde desktop1) dies. This also happens
whenever I shut down my tv-xserver. The second monitor will stay on, and 
the kde session on it will continue fine. This is really wierd,
since both kde sessions are running on the same primary-xserver in 
dualhead-mode..

Well.. I only have very little C experince myself (I'm a java guy), so 
I'm afraid I won't be able to help with the C-debugging,
but I'll gladly help with any tests you might still come up with. I'll 
still try different kernel and x server combinations to try to
isolate the problems..
