Description Jeff Litvak 2004-09-08 15:22:00 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3)

Description of problem:
After updating to the latest kernel, X server fails to load. Automatic
configuration correctly finds that I have an Intel 810 video chip, but
fails with the error message "No Screens Found."

Works fine under all previous versions of the kernel.

I'm running an HP Pavilian 502N with a Compaq MV920 monitor, 1920
resolution with thousands of colors.

Version-Release number of selected component (if applicable):
kernel 2.4.21-20.EL

How reproducible:

Steps to Reproduce:
1. Boot the machine to the 2.4.21.-20.EL kernel.

Actual Results:  Error message appears that X Server cannot be
started. I'm then prompted to look at the error results and to
automatically reconfigure the X server. Though the reconfiguration
utility correctly finds my video chip, it fails to start X, showing
the error message "No screens found."

Expected Results:  Would like to have X started automatically when
machine is booted

Additional info:

I've saved the log files when the error occurs. Let me know and I'll
send them to you separately.

Reassigning to kernel component, as that's what changed.

Comment 5 Neil Horman 2004-09-14 13:11:02 UTC
The first thing in my mind to check would be the existance of
/dev/agpgart.  From the error message in the log it looks as if the
first problem you hit is that it cant find that device interface.

If /dev/agpgart doesn't exist, or exists with the wrong major and
minor numbers, try running:

mknod /dev/agpgart c 10 175

Then try starting X again.

Comment 6 Mike A. Harris 2004-09-14 13:41:01 UTC
Try rebooting the machine, then starting up X with "startx", and
assuming it fails, attach /var/log/messages from boot time onward
using bugzilla file attach.


Comment 7 Jeff Litvak 2004-09-14 15:17:46 UTC
I restarted the machine and attempted to run the mknod command. It
failed, showing a message indicated that the agpgart device already
existed. I was able to see it when I built a listing of /dev.

I'm nervous about trying to delete it, as I don't want to farkle my
ability to start X using earlier versions of the kernel.

Messages file generated after trying to manually run startx

Here is the messages file that was generated when I booted to the new kernel
and attempted to run startx. Hope it's of help to you in figuring out this

Comment 9 Kostas Georgiou 2004-09-24 13:10:06 UTC
One of my users has the same problem "agpgart fails to load with: No
such device". Going back the previous kernel fixes the problem. 
Any agpgart changes in 2.4.21-20.EL ?

Comment 10 Kostas Georgiou 2004-09-24 13:16:23 UTC
Ah duplicate of bug# 131907

Comment 11 Mike A. Harris 2004-09-24 13:55:12 UTC
Indeed, bug #131907 does appear to be the cause of the problem.
I'll close this bug as a duplicate of that bug, and we can track
future updates to the issue in the master duplicate.

Thanks for pointing out the real problem.

A fix for this problem has just been committed to the RHEL3 U4
patch pool this evening (in kernel version 2.4.21-22.EL).
