Description Max Rible 2002-06-09 15:57:40 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020606

Description of problem:
Under Red Hat Linux 7.2, my system (1GHz Pentium Coppermine with 256MB RAM, 30GB
disk, Intel 82810E DC-133 Chipset Graphics Controller (rev 03) (prog-if 00
[VGA]) with 4MB RAM) was able to run in 1280x1024 mode with 16-bit color.  When
I upgraded to Red Hat 7.3, XFree86 failed to start, and I had to take the system
down to init 3 to turn off the flailing kdm and run Xconfigurator. 
Xconfigurator was able to get 1280x1024x8 or 1024x768x16 working, and if I lied
and said I had 8MB of video RAM instead of 4 I could bring up a fine-looking
1280x1024x16 screen with no working mouse or keyboard driver, but I couldn't get
1280x1024x16 back.

Version-Release number of selected component (if applicable):
"rpm -q XFree86" reports XFree86-4.2.0-8.

How reproducible:

Steps to Reproduce:
1. Install Red Hat Linux 7.2 on an i810 system with 4MB video RAM.
2. Run Xconfigurator, set to 1280x1024x16bit, 4MB RAM.
3. Upgrade to Red Hat Linux 7.3.

Actual Results:  When the system came up, kdm began flailing because XFree86 was
failing to start properly.

Expected Results:  The system should have come up in 1280x1024x16 mode.

Additional info:

I will attach my XFree86.0.log and XF86Config-4.

Are you using our kernel, or a self-compiled one?
Please attach the output of "uname -a" and "rpm -qa | grep kernel".

It appears from the log that your machine is not able to get AGP memory,
and that is causing it to fail.

This happens with kernel-2.4.18-3 (installed with 7.3) and kernel-2.4.18-4
(provided by up2date).  agpgart is apparently loaded, according to lsmod.  I
haven't changed the CMOS settings from the ones that worked under 7.2, but I'll

Comment 9 Mike A. Harris 2002-11-07 06:56:07 EST
Please try the latest developmental XFree86 CVS packages from

This should solve the problem you're having.  Setting bug state
to MODIFIED.  If the above package works as expected, please close
bug as RAWHIDE, or indicate that it is working now.  Otherwise
if the problem continues, please set to ASSIGNED.
Comment 10 Max Rible 2002-11-09 19:31:09 EST
I loaded up the packages as requested.  (Colormaps are now really freaky in
1280x1024x8bit, by the way.  emacs, bugzilla, and console all look okay when I'm
focused on them, evolution looks weird even when it has focus.)  Installation
(rpm -Uvh *.rpm) generated only one error message:
/var/tmp/rpm-tmp.99506: line 1: xftcache: command not found

The system still works in 1280x1024x8 (with the aforementioned colormap
freakiness) but fails to do so in 1280x1024x15 or 1280x1024x16.  I will attach
the files XF86Config.8bit and XFree86.0.log.8bit to show a successful X startup
and XF86Config.16bit and XFree86.0.log.16bit to show an unsuccessful one.

Comment 16 Max Rible 2002-11-30 18:18:33 EST
I have found a rather peculiar workaround.  I'm lying to the system about its

Last time I tried this stunt was under Red Hat 7.3, and it failed miserably, as
documented above.

Lying to Red Hat 8.0 is *much* more effective.  I've got antialiased fonts
running now, and the xft mozilla 1.2 running just fine.  I've got a system
uptime of 7 days without any odd behaviors.

It's not a fix, but at least it gets the job done.  I hope that sheds some light
on the matter.
Comment 17 Mike A. Harris 2004-01-10 10:41:58 EST
Red Hat Linux 7.x and 8.0 are no longer supported by Red Hat.  Please
upgrade to one of the following OS releases and see if you still
encounter this problem:

- Red Hat Linux 9
- Red Hat Enterprise Linux (version 3)
- Fedora Core 1

Ensure that your system then has all updates installed which have
been released by Red Hat since the initial release of the OS version
that you are using, and that you've rebooted your system into the
newest Red Hat kernel.  Also make sure that you are not running
any 3rd party kernel modules or video drivers.  If the problem still
exists in one of the above OS releases under these circumstances,
please read the i810 manpage, and see if any of the options it
describes might be relevant to the problem you are observing.  After
experimenting with any useful options, if the problem still exists,
please file a new bug report in bugzilla and attach all relevant
configuration details, etc. as in this report.  You may also want
to file a bug report upstream to XFree86.org in their bugzilla,
located at:  http://bugs.xfree86.org

Closing bug WONTFIX currently, as this OS release is no longer
supported, and it isn't known wether the problem occurs under
a supported OS release yet or not.
