syslog shows kernel complaining about "Invalid ROM contents" on the Matrox video device...

15:59:02,506 ERR kernel:pci 0000:07:00.0: Invalid ROM contents

...but this is also seen in earlier releases of RHEL that didn't have this video problem.

This is a bug in the mga driver.  The vesa driver is what worked for you.

Can you test with the following updated package?

Xorg.0.log using driver xorg-x11-drv-mga-1.4.13-6.el6.i686.rpm

Hi Adam,
I loaded the i686 mga package on the system I managed to get installed using basic video mode and deleted the (minimal) xorg.conf that specified the vesa driver and restarted X and was unable to get anything to display.  The Xorg.0.log is attached.

Xorg.0.log with updated mga driver

The Xorg.0.log I attached earlier was with a hacked xorg.conf.  This attachment is the right one, after I had deleted the xorg.conf.

OK -- this is really weird...
After sitting idle for some time, the login screen was displayed but it goes black as soon as there is any input (mouse movement.)  Almost like a case of dyslexia with the screen saver.

Sigh, looks like the RANDR 1.2 feature isn't ready on those chips yet.  Easy enough to back out, but unpleasant.

If you use an xorg.conf like:

Section "Device"
    Identifier "mga"
    Driver "mga"
    Option "RANDR12" "off"
EndSection

do you get a working display?

Hi Adam,

With the xorg.conf you specified, when I kill the X server and it restarts, the Login screen displays fine.  But as soon as I log in there the signal is lost.

Okay, I think I know what this is.  Please try this new test driver (without the xorg.conf hack above):

Hi Adam,
It works!  I didn't do extensive testing but after starting X with the test driver and logging in the desktop is displayed correctly.
Thanks!
Don

Hi don,
As for xorg-x11-drv-mga-1.4.13-6.el6.test1.i686.rpm, in my environment, 
a panel is not displayed correctly. 
The icon of "Register System", "Network Conection", and ... are not displayed on a panel.
(See attached file: xorg-x11-drv-mga-1.4.13-6.el6.test1.i686-panel.png)

There is no problem in the driver of RHEL6.2. 
(See attached file: xorg-x11-drv-mga-1.4.13-3.el6.i686-panel.png)

Is a panel displayed correctly in your environment?

Hi Haruo,
The Sound and Network Manager applet icons are displayed on the panel, as expected, in RHEL6.3 snapshot4 (with both the vesa driver and the mga test driver) on my IBM 3650 M3.  Even if they aren't on your system I don't think that would be related to the mga driver.  I think it would be something from gnome, or possibly a difference in the hardware detected on the system.

Hi DOn,

Thank you for explaining it.
In my environment, an icon is displayed on a panel vesa-2.3.0-2.el6 and mga-1.4.13-3.el6. However, an icon is not displayed on a panel drv-mga-1.4.13-6.el6 and drv-mga-1.4.13-6.el6.test1. (See attached file: xorg-x11-drv-vesa-2.3.0-2.el6-panel.png)

I think that the issue as which an icon is not displayed on a panel is related to a mga driver.

In mga-1.4.13-6.el6 of RHEL6.3 snapshot4, although Network Manager applet icon is running, it is not displayed on a panel. Notification Area cannot be added to a panel.

I verified that RHEL6.3 RC (i686) contains the driver package with the fix and that video does work with that mga driver.
