Default Login Screen Resolution issues

Hi,

my uprade from LTS 6.06 to LTS 8.04 went fine. Congratulations to the
update-team!

But: My login screen has the wrong resolution (this is not a big issue).

This is the relevant part of my xorg.conf (1280x1024 is the correct
resolution):

--8<---------------cut here---------------start------------->8---
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies, Inc. Radeon 9600 SE (RV350 AQ)"
Monitor "B101715"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 8
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 15
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
--8<---------------cut here---------------end--------------->8---

I have also tried rebooting with everything below "1280x1024" deleted
from xorg.conf. The login screen still displays incorrectly.

Any ideas?

TIA

Patrick

this may sound a silly question but when you boot is you monitor on or
switched to another computer i run 3 machines if the linux (ubuntu )
is not switched through to the monitor it boots with a resolution of
800 x 600
if your monitor is of the older CRT type it may be it does not switch
in in time for Ubuntu to get the capability of the monitor.

Thanks for your feedback Mike!

I do not think this is the problem, because the login screen was
dislayed with the correct resolution with Ubuntu 6.06 (before the
upgrade). The monitor is a TFT (Belinea model 101715).

Cheers,

Patrick

What if you tried removing all the old cruft from your xorg.conf and
test the fancy new autodetection? Make a backup of your
/etc/X11/xorg.conf file and run the command:

sudo dpkg-reconfigure xserver-xorg

(That should make it's own backup before changing anything, but why
trust automation when you can do it yourself.)

Err, make that:

sudo dpkg-reconfigure -phigh xserver-xorg

Either way works, but the -phigh will put you through less questions.

Something to add to this:
You can change the level of questions that the reconfigure process asks.
run "sudo dpkg-reconfigure debconf"

You can set the importance level to "low", where it will ask you about
every detail when you (re)configure anything in the future (xorg?). I
believe the default is "high", which causes dpkg to ask you only
high-importance questions.

If you set it to "low" importance, when you reconfigure xorg, it'll
ask you some more specific questions, which may or may not help you
solve your problem.

Thanks for the feedback Rashkae! I will give this a try on the weekend.

Cheers,

Again, thanks for your feedback.

I tried your solution (with and without the extra options "-phigh"),
restarted the xserver, and the _login-screen_ still has the incorrect
resolution. The display resolution is fine during a normal gnome
session.

After reconfiguring my xorg.conf looks like this:

--8<---------------cut here---------------start------------->8---
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "de"
Option "XkbVariant" "nodeadkeys"
EndSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Emulate3Buttons" "true"
EndSection

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
EndSection
--8<---------------cut here---------------end--------------->8---

Any other ideas?

TIA

Patrick

Hello,

what helped me was to add the following subsection to the screen section
Section Screen
...
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600"
EndSubSection
...
EndSection

The *first* mode is the one used by gdm

Don't forget to save a backup copy of xorg.conf in case the system
refuses to start!

cd /etc/X11/
sudo cp xorg.conf xorg.conf.working_backup
before starting the editing

and
cd /etc/X11/
sudo mv xorg.conf.working_backup xorg.conf

if something bad happens :-)

Cheers,

Michele
