[opensuse-xorg] Manually configure screen resolution
Hi I have just installed 11.3 and am having a problem with the graphics resolution. My screen is actually a TV which does not report its characteristics (1280x720@60Hz). X automatically configures itself to 768x576@50Hz and the screen scales this in such a way as to shift the top, bottom and left side off the physical screen. The installation is fine when attached to a 'normal' monitor (X correctly autoconfigures 1024x768@60Hz). The TV screen functions correctly under 11.2. I tried copy the relevant lines from my old, functional xorg.conf into the new one - but there is no xorg.conf and the use of the files in xorg.conf.d is opaque without adequate documentation. I tried running sax2 to create a xorg.conf file, only to discover that the utility doesn't seem to exist any more. Can anyone tell me how to manually configure X for the required resolution - what information needs to go into which files now there's no central xorg.conf?

You're in a big club. :-(

Which connection type are you using? Maybe switching cable types will permit correct detection. What size is your TV?

/etc/X11/xorg.conf is an optional file. You tried your 11.2 xorg.conf and it didn't work?
the use of the files in xorg.conf.d is opaque without adequate documentation.
For sure. Each of the skeleton files there is supposed to allow you to incorporate sections of what used to need to be in xorg.conf. What you may need is a modeline and/or a PreferredMode.

'X -configure' will create a skeleton xorg.conf.new(?) that you can build upon.
Can anyone tell me how to manually configure X for the required resolution - what information needs to go into which files now there's no central xorg.conf?
Much more help than above requires knowledge of your video chip and preferred video driver, may require nomodeset on your cmdline, and possibly a rebuild of your initrd to disable KMS. I've been running Factory on 7 machines for several release periods. I expect not to install 11.3 on any of my regular systems due to the alpha/beta reality states of KMS & Xorg that are incorporated into 11.3. I'm currently planning an upgrade of my main box from 11.0 to 11.2. Did you really need to "upgrade" from 11.2? Given the time of day and day of week, I suggest inquiring also on the xorg list if you hope results in relatively timely manner: http://lists.freedesktop.org/mailman/listinfo/xorg -- "The wise are known for their understanding, and pleasant words are persuasive."

Doing both of those has fixed the problem - thank you muchly. Dylan -- “ ‘... but there is so much else behind what I say.
