install in 1280x1024

Ton anglais c'est parfait.

In order to resolve this issue we need to understand what went wrong.
To do this we need, as a minimum, the output of lspci -vv and lspci -vvn as well as a copy of your /var/log/Xorg.0.log and your /etc/X11/xorg.conf.

Many thanks in advance for your cooperation.

also, /var/log/casper.log from the livecd-session is valuable.

I join the files :
- /etc/X11/xorg.conf (I removed "1280x1024" in the Display Depth 16 and
24 )
- /var/log/Xorg.0.log

and the results of
lspci -vv
lspci -vvn
lsmod

Thanks for all the information.

This is actually the opposite of the problem most people get. ;-)

Can you please attach your /var/log/Xorg.0.log and the error message you received when booting with the 1280 resolution? Normally X should be smart enough to detect that this resolution is too high, and not try it. The error message and Xorg.0.log will give us better information.

Stephane, could you please attach your /var/log/Xorg.0.log file when booting in this manner?
