Xorg.0.log with std graphic card

I though I'd already reported that one but it looks like I did so only through mail

Can you attach your /root/drakx/report.bug.xz please?

There's no /root/drakx/report.bug.xz, do i have to create it manually?

No, it's created by the installer at the end of installation.
So this is not a classical installation?

Ok, i thougt it's generated in case of an error, e.g. if the X-Server doesn't start. The attached one is from an KDE-Installation with no online updates.

Either this bug has an easy fix (Thierry? Thomas?), or it will have to be fixed for Mageia 6 I guess, we're really close to the final release.

I think the problem is in the generated xorg.conf (/tmp/Xconf) in stage2. I've created an "Usb Install", and unsquashed the mdkinst.sqfs and changed some options of the configfile. It seems to me, that the X-Server breaks at the "Depth"-Configurations in the xorg.conf file, commenting them out makes the X-Server start as expected.

Another workaround: setting the depth in the grub.cfg to 32 makes the X-Server start with the default mdkinst.sqfs

The next workaround, without altering anything on the DVD:

Edit the grub section "Start Mageia 5 (Cauldron) Install", insert 

set gfxpayload=1024x768x32

before the kernel/linux-line (screenshot attached), works with both cirrus and std graphic card

It's strange that fb fails with 24bpp...

(==) Depth 24 pixmap format is 32 bpp
(EE) FBDEV(0): FBIOPUT_VSCREENINFO succeeded but modified mode
(EE) FBDEV(0): mode initialization failed
(EE) Fatal server error:
(EE) AddScreen/ScreenInit failed for driver 0

Summary: M5RC qemu efimode: DVD installer does not start X-Server => M5RC qemu efimode: DVD installer does not start X-Server (unless explicitly choosing 32bpp)

The above workaround works only with -vga std, for the cirrus card you have to reduce the resolution to 800x600x32

No problem with MGA5 final (Mageia-5-x86_64-DVD.iso) anymore, this bug can be closed, i think. Thank you.

thanks
