Blank screen after xserver autoconfiguration - incorrect monitor settings

[Krzysztof Lichota]

I have tried installing Kubuntu Breezy preview (daily build 20050902).
Xorg version in it is: 6.8.2-56.
My graphics card is Nvidia Geforce FX 5200.
Monitor is Sony CPD-E400E.

During installation I was presented with resolutions up to 1024x768, so I chose manually also 1280x1024.
It works fine on Suse with refresh rate 88Hz, so it is supported by monitor.

After booting, xserver started but the screen was blank. I could switch to text consoles, but switching to vt7
always gave me blank screen and monitor entered power saving mode.

I run dpkg-reconfigure xserver-xorg and this time chose resolutions up to 1024x768 and then it started OK, but
the refresh rate was only 75Hz.

Xorg log from failed start

This is log from failed attempt to start - probably, I might have overwritten
it during reconfiguration and following restart of Xserver.

This is log from last start of Xserver (successful).

This is xserver config for failed start.

This is Xserver config which worked.

If you run sudo dpkg-reconfigure -phigh xserver-xorg, and allow autodetection of
your monitor, is everything okay then? I think this is yet another
broken-CD-generation bug (no xresprobe).

I have run the above command:
1. Text screen during reconfiguration was garbled.
2. It didn't ask me about autodetection of monitor, I got first screen - choosing video
driver ("nv" was chosen by default, so I left it that way), then screen with resolutions - it
was garbled but I am pretty sure 1024x768 was the highest resolution marked).
3. After starting kdm back I have resolution 1024x768 at 60Hz. So it is still not OK.

do you have the xresprobe package installed? try dpkg -l xresprobe. also dpkg
-l discover1 discover1-data.

xresprobe is not installed, neither is discover*.

That's the problem. These packages are needed for autoconfiguration. They are
installed by default when installing Ubuntu, though it is possible that the
daily build you tried was buggy.

Try the preview:

and reopen this bug if you still have a problem.
