7.04 Beta: X Config Failure at Installation

Thank you for your bug report.

ytene:
Please attach these files:
/etc/X11/xorg.conf
/var/log/Xorg.0.log

It might also be interesting to see the output of:
xresprobe nv
too

Hi Brian and Sitsofe,

Please accept my apologies for taking so long to respond to you. Today I made another attempt at a clean installation of 7.04 but I got the same result. [At least it is consistent]. I have a variety of files to offer you by way of attachments - I hope that I can append more than one at a time. Here is a quick explanation of the files I am sending you, file name by file name...

xorg.conf.orig - this is the xorg.conf file that is created by the installer
Xorg.0.log - this is the log file generated from the above config file
xorg.conf.test - this is my hacked version of the file, including the extra parameters which have worked before
Xorg.0.log.old - this is the log file generated when running my hacked config file, complete with extra errors
xresprobe.txt - this is the output from the "xresprobe nv" command that you asked me to try...

I hope that all the above help. That you again for being kind enough to look at this for me...

Regards,

C

Footnote -

When I checked the contents of Xorg.0.log I saw the error messages relating to the resolution stanzas I had added and the "unknown mode" that is listed as either the reason for the failure or a symptom of my careless tweaking of the file. I'm guessing that this means that either xorg.conf is incomplete, or that there is another file that may need adjusting. Without making any more changes, I'll continue to trawl around and see what I can find.

Once again, I really appreciate your kind assistance here. Please don't hesitate to let me know if there is more information that you need.

Thanks and Regards,

C

Duh!!

I'm sorry guys, I forgot to mention one more important thing. The original posting was made after using 7.04 Beta from the CD image. All the above files and data - ie the posts in response to your information request, come from installing from the production release of 7.04, AMD64 chipset, and from the DVD rather than the CD iso. In fairness I don't suppose the DVD/CD piece makes much difference, but perhaps the switch to the production codebase might be more important.

Hi ytene,

Thanks for the detailed bug report! It looks fairly clear that this is another case of bug 3731, based on seeing the "Generic Monitor" in your xorg.conf. The xresprobe.txt is also empty of content. I've found this could happen for a few reasons: I suspect ddcprobe (which xresprobe depends on) sometimes fails to work - you could check by trying to run it and see if it segfaults. Another reason this can happen is if for whatever reason your monitor does not provide EDID information for whatever reason, or if your graphics card or its driver does not carry it through.

While there have been a number of simpler workarounds suggested, the only one that seems to work reliably is what you did - manually hack the xorg.conf file. One thing to be sure is to check the refresh rates listed for your monitor are correct according to your documentation (sometimes the detection mechanism detects them incorrectly.) On a positive note, 3731 is my #1 priority bug, and I'm very hopeful we can get a solution to it for gutsy.

Hi Bryce,

My experience differs to "the only one that seems to work reliably is what
you did - manually hack the
xorg.conf file". The best I ever achieved is a locked in proper resolution
and refresh rate but one easily broken when I tried to install 3d drivers.
Having a barely working system is like driving a car on a flat tyre, it can
be done but isn't acceptable as an end result for average use.

You wrote "On a positive note, 3731 is my #1 priority bug, and I'm very
hopeful we can get a solution to it for gutsy." This is good to hear
as 7.04is the worst release of Ubuntu I have so far used - because of
this bug
which seems worse than previously.

Let me know when you have a solution you want tested. A proper download and
not some hack. I can hardly recommend Ubuntu and then give detailed
instructions on how to use the command line and modify xorg - my friends
would not waste their time on such a broken software and rightly so.

Without a proper fully functioning screen resolution and refresh rate, a
person can't even begin to use Ubuntu.

All the best Bryce,

Chris

I agree. My friends are not very enthousiastic about this bug.
I was lucky I guess. The screen started at 800 x 600 which is just large
enough if you move the top and bottom bar to the left and right side of
the screen. So I could do the installation. After that I used the
xresprobe trick, simply by using the package manager. Problem solved. I
understand it doesn't work on every system and don't know an other
trick. I'm not really an expert.
Good luck

Oh yes, forgot to tell.
Yesterday evening I installed Kubuntu 7.04 on a friends PC with hi-res
CRT 1600 x 1200, 500 MHz processor and 256 M memory. We used the text
mode for installing and it worked very nice. Earlier attempts with
Ubuntu 7.04 failed. Again, I don't understand why.
