Red Hat Bugzilla – Bug 1588
Kern3l 2.2 Frame Buffering vs. Netscape
Last modified: 2008-05-01 11:37:49 EDT
I upgraded a 5.2 RedHat install to the new 2.2 Kernel. I
enabled frame buffering for a S3 Trio 3d (86C366) video
chip. Everything works wonderful. The kernel is fast, and
X-Windows rocks when run through this new feature.
Unfortunately, there is a bug.
When I run netscape, then run a Java applet, Netscape
crashes. I installed another video card and turned off
frame buffering, and it works, so I am pretty certain that
it is something to do with frame buffering and Netscape's
Has anyone approached this problem? It will sure to be a big issue
DKL, I have about 2500 installs that need this to work. Have you
I haven't been able to duplicate it here. Is there a specific
web site you can point me to that causes it to die?
I can get it to crash by selecting the Java console from the netscape
menu's. [Communicator->tools->Java Console] I just upgraded to kernel
2.2.5, and I am using Communicator 4.5. I used the instructions at
www.uno.edu/~adamico/banshee to setup for Frame Buffering, and the
for the kernel 2.2.5 install. The machine I have been working with is
an IBM 300GL. The video chipset is the S3 Trio 3D (86C366), which
explains why I am trying to do frame buffering, i.e., no suitable
X-Window drivers I know of.
Everything else seems to work flawlessly using frame buffer. It seems
to only affect Java within netscape. When I installed another video
card, and turned off frame buffering, it worked fine even with the
same kernel image.
I can not remember if I tried this on a different machine. If you
like, I can give it a try on a different piece of hardware.
I tried this on an Acer box with a different chip. Running off of a
normal X-Window driver, it worked. With Frame Buffering, everything
worked until Netscape called a Java function.
I've been told that Caldera has promised to find a solution for us.
I'll keep you updated.
Thanks -- Bob
How many bpp are you running at?
Also, are you running XF86_Xvfb on top of the frame
buffer, or with a standard server?
I am running something called XF68_FBDev I downloaded from
www.uno.edu/~adamico/banshee. I am using "VGA=791" in my lilo prompt,
which is indicated in www.uno.edu/~adamico/banshee/files/vesafb.txt to
be 65,536 colors at 1024x768. Do me a favor, and send me a copy of
your driver and XF86Config file, for it might be wise to rule out
problems with the code I am using. Also, what version of Netscape are
you using? I am using version 4.5 downloaded from the Netscape web
site for the 2.0 kernel; there is none for the 2.2 kernel.
What I've been testing on is the following:
Matrox Millenium using matroxfb
XF86_FBDev from the 18.104.22.168 release
Netscape 4.51 (glibc-2.0 version)
Are you using the glibc or libc5 version of Netscape?
(Running ldd on it will tell you; if a libc.so.5 shows
up at all, it's the libc5 version.)
Also, are you running with a font server or with a local
font path? If so, what is the font path set to?
