std-out/stderr log from 'startx' with Matrox driver (1.55 KB, text/plain)

Description R P Herrold 2007-12-08 20:21:51 UTC
Description of problem:

I now get an X configuration which works as root, but not as non-root, similar
to that reported in bug: 238508;  the error occurs with both the i810 driver
which is the onboard Intel 965 chipset, which seems to call for the i810 driver.  

This is a regression in function from the setup shipped in RHEL 5

I tried using an add in PCI Matrox card, to see if it was 810 driver specific
(which seems to be mentioned in several s-c-d bugs)., but the issue persists
when starting X as non-root with a configuration file made by s-c-d

I will attach trace if you wish

I can build and install s-c-d from rawhide if you wish; alternatively a test
candidate is file for me to rebuild from SRPM as well.

The unit in our stable with this issue is unit: 231

Strangely it all worked without an /etc/X11/xorg.conf  pre-RHEL 5.1, with the
5.0 product

errors and warnings in that file are as follows:

[herrold@dhcp-231 log]$ grep WW Xorg.0.log
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(WW) VESA(0): Failed to set up write-combining range (0xd0000000,0x400000)
(WW) <default pointer>: No Device specified, looking for one...
[herrold@dhcp-231 log]$ grep EE Xorg.0.log
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
[herrold@dhcp-231 log]$ 238508 

Version-Release number of selected component (if applicable):

system-config-display-1.0.48-2

How reproducible:

remove old /etc/Xqq/xorg.conf file
run s-c-d
try to startx as non-root

Steps to Reproduce:

as above 

Actual results:

-- X starts as root, and not as non-root.

Expected results:

startx should work for all users after re-running s-c-d

Created attachment 282091 [details]
std-out/stderr log from 'startx' with Matrox driver

note the 

(WW) MGA(0): Failed to set up write-combining range

messages -- these are present with the i810 driver as well

Comment 2 Matěj Cepl 2007-12-13 23:24:10 UTC
We could probably use whole logs, not only greps through them. Please attach
your X server config file (/etc/X11/xorg.conf) and X server log file
(/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Comment 3 Matěj Cepl 2008-01-17 12:25:21 UTC

Comment 4 R P Herrold 2008-04-08 18:03:20 UTC
I am suppy -- the email requesting update was missied -- I will attend to this
as soon as I can set up a test environment - please give me 2 weeks.

thanks

Comment 5 Matěj Cepl 2008-04-09 11:15:55 UTC
Request granted :-)

Comment 6 R P Herrold 2008-05-12 19:44:13 UTC
setting test unit up today

Comment 7 R P Herrold 2008-05-27 14:50:18 UTC
needed hardware left my control -- cannot test further -- sorry

I cannot close this bug with my bugzilla permissions, even though I was the
original reporter -- please do so for me

thank you
