Description Florian Knell 2005-06-17 05:04:57 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; de-DE; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Description of problem:
The Installer is not able to display an correct screen after probing the hardware.
If i use DVI-input the monitor screen turns to black and the osd said i should check the frequencies, cause they are out of range.
I could reproduce the problem with an 19" CRT and the LCD form above with analog input. But in this case the screen turn not into black and i see interferences like white vertical bars, some flick flack and so one...

I installed the system in text mode and tried to configure the X-server manually later. After a few hours i gave up with the same results which i descripted above.

If necessary i would post logfiles or xorg.conf.

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


How reproducible:
Always

Steps to Reproduce:
Running Installer from CD with Matrox G550 graphics adapter or try to run xserver after installing the system in text mode.

Additional info:

Matrox G550 dvi and analog output
Iiyama ProLite 431s TFT with dvi and analog in
Videseven 19" CRT monitor
Comment 1 Mike A. Harris 2005-06-17 12:45:08 EDT
The "mga" driver does not support DVI officially.  It contains only
experimental code which Matrox never completed into a stable workable
state.

After using analog cable instead, please reproduce the problem and
attach your X server log and config file using the link below.  There
are numerous problems with mga support currently, so this is likely
a duplicate.  Once we have your details, we can determine if it is
the same issue already reported, or a new issue.

TIA

I tried at first the analog output, because i had that dvi problems with every
linux distribution i installed. The difference between them and the fc4
installer was analog works fine and dvi works after installing the mga-driver
from Matrox. 

Frusted of my results i recoverd the old installation. I could run the installer
and could attach the X server log, but not before tomorow. Hope thats okay.

I'm not able to copy the X server log. After starting the X Server the complete
commandline output turned to character salad. This happend on every terminal.

I made some bad screenshots with my mobile cam, if it's hopefull i will attach them.
Comment 5 Mike A. Harris 2005-06-23 15:13:25 EDT
This problem is believed to possibly be a duplicate of libvgahw.  Please
read bug #161242 and test the libvgahw.a module that is available at
the following URL:

    ftp://people.redhat.com/mharris/libvgahw.a

Make a backup copy of the original libvgahw.a module prior to replacing it
with the one from above.  Once you've replaced it, restart the X server or
reboot the system.  After doing this, please indicate if there is any change
in the problem.  You may wish to CC yourself on bug #161242 as well, assuming
this does turn out to be a duplicate.

Also, please attach your X server log from /var/log and your X server config
file /etc/X11/xorg.conf to all X related bug reports, as this makes it
easier for developers to perform a diagnosis.  You can get the logs by
setting "initdefault" to 3 in /etc/inittab and running "init 3", then
using "startx" to start the X server.  If the machine crashes or display
is corrupted, reboot, and backup the logs after rebooting *before*
starting X again.  Attach those to the report.


Thanks in advance.
Comment 6 Florian Knell 2005-06-23 17:19:48 EDT
It's definitively an dublicate of bug #161242.

During the start up of the installer imho it is not possible to replace the
libvgahw and there is also no way to get an copy of the x server log and config.

I recoverd my old OS because i need my box for daily working.
