Description of problem:

I have a Thinkpad SL510, with ATI graphics card. Most other major distros with the vanilla open-source radeon driver is able to set the natural resolution, which is 1366x768. (Early or late during startup. For example, Ubuntu would usually present me with a 1024x768 splash screen, but after some flicker the resolution jumps to 1366x768. Fedora is able to get the right resolution just after I hit the entry in the bootloader.) However Mageia fails... Here is how it fails, quite a long tale.

In the bootloader screen I left the "resolution" menu untouched. Mageia boots and I see the splash screen, in resolution 1024x768. After a while the screen goes blank, and I'm dropped in the console, which says "entering non-interactive startup". I noticed that the resolution gets right, i.e. 1366x768. And when the pre-login setup appears (asking keyboard layout, time zone, etc.), the resolution goes to 1024x768. After I finish this, I can see the getty prompt "login: " for about two seconds, and this time the resolution is right. But immediately I'm taken into X, and the resolution is wrong again. I found "Monitor" in the GNOME menu, and was able to confirm that the resolution is 1024x768. I can change the resolution right here, but after that the panel layout looks funny as applets that are supposed to align to the right retained their previous absolute coordination.

It seems Mageia struggled many times to get the resolution right, but failed in the end. I'm a guru in debugging graphics related issues, but I'm willing to help to investigate the problem if guidance is offered.

Version-Release number of selected component (if applicable):
1 beta 2, the GNOME Live CD, though I believe other live / installation media would suffer from the same problem

How reproducible:
Every time Mageia boots.

Steps to Reproduce:
1. Have a Thinkpad SL510 ;) It's a natural assumption that some other types with ATI graphics card and widescreen monitor will also do, although I cannot name any.
2. Boot into the Live or installation media.
3. Observe the resolution.
4. You may need to reboot and observe several times to memorize what happens in which order ;)

What kind of ATI graphic card do you use?

It seems I have a similar problem with my 
Thinpad Edge13 with a ATI Mobility Radeon HD4225

The KDE-Live-Cd don't get the right solution (only 1024x768)
After the installation I can change to 1366x768
Wgen I stop the system I see some flicker with the last display

Do you need the same three infos from the system with the running proprietary driver?

I think the problem here is the EDID data is confusing X, so it defaults to 1024x768:

If you open as root:
drakx11

open Monitor, expand "Generic" and select "Flat Panel 1366x768", then log out -> log in, does it use the correct resolution? if so, please attach the new xorg.conf and Xorg.0.log (without restarting X again).

Comment 17 Anssi Hannula 2011-05-04 20:47:42 CEST 
The problem is known to me, and the correct fix for this issue is to rely on X.org autodetection instead of 1024x768 when EDID detection fails, at least on laptops.

I'll try to fix this as soon as I have some time.
Comment 18 Magnus Rasche 2011-05-04 20:55:44 CEST 
I must change both the monitor to "Flat Panel 1366x768" and the resolution to "1366x768".
After log out/in the resolution is ok :-)

Do you need xorg.conf and Xorg.0.log?
Comment 19 Ahmad Samir 2011-05-04 21:18:12 CEST 
No need, Anssi already acknowledged the bug, so he has all the needed info :)
