Public bug reported:
Binary package hint: xserver-xorg
Hi!, after upgrading from Ubuntu 8.04 to (today) Ubuntu 8.10 Beta, via
update_manager I got an useless Desktop, because GDM stops from appear,
instead the screen just flickers when it has too appear (GDM).
The culprit, I think, is xserver-xorg. I had configured my driver in
xorg.conf as "i810" but new 7.4 Xorg rejects it, it will give a lot of
errors complaining about it.
Problem is partially solved doing a dpkg-reconfigure xserver-xorg, but I
lose my Monitor modelines, needed to get 1024x768 (otherwise, from Xorg
autodetection, I only get 800x600).
If I use displayconfig-gtk, I can choose my monitor (AOC Spectrum 4V),
my video chipset (i180), and my desired resolution (1024x768). Problem
is that xorg.conf generated by it (displayconfig-gtk) is not accepted by
Xorg 7.4, because the keyboad, mouse and even the i810 driver
specified...
To sort my problem I have to copy the modelines generated by
displayconfig-gtk, then run dpkg-reconfigure xserver-xorg, copy the
modelines in the new xorg.conf and I got a useful Desktop again.
I mean, this is a big incompatibility problem between old xorg.conf and
new 7.4 Xorg. Because that, GDM didn't load in my case (just after the
upgrade) because it was using a 1024x768 that Xorg did not accepted at
the moment, instead of GDM it showed garbage and freezes.
I had to change to TTY1, stop GDM, kill X, and run "startx" to get my
Gnome Desktop (at 800x600), thing which was not so easy to figure it out
at first time...
Please, if you can improve Xorg support for i810 (which was extra fine
in Hardy), it would be greatly appreciated :)
Thank you!
