Okay..so I've posted a similar question before but the situation is a little different now. I'm running Kubuntu 11.10 and I can't get KDE to save my default display resolution once I've changed it in K.
I'm running an older IBM Thinkpad T30 and my ATI Radeon Mobility 7500 is no longer supported by the proprietary ATI linux driver (so I left it to the default driver..did not try installing ATI one).
I've done a little reading up and I know by default Oneiric Ocelot (11.10) does not have an Xorg.conf file but I can't figure out how to generate one. Or where to copy it to.
See this to generate an xorg.conf file for K/Ubuntu: http://askubuntu.com/questions/4662/...figure-x-there
You can then edit the xorg.conf to your needs.
You can also try using xrandr: https://wiki.ubuntu.com/X/Config/Resolution
You can also try looking into and editing the files located in /etc/X11/xorg.conf.d/. The newer versions of Xorg use those files as well.
I know that this seems more complicated than it used to be when you just had to know about the xorg.conf file. Things are supposed to work automatically nowadays. However, things get more complicated when automatic configuration fails.
if I'm in recovery mode do I need to specify root (via 'sudo') or is this the default?
When you boot into recovery mode and drop to the root shell you are root. Therefore you do not need to use sudo.
In my last post I suggested looking at the files in the /etc/X11/xorg.conf.d/ directory. However, on my
Lubuntu 11.10 system I do not even have a /xorg.conf.d/ directory in the /etc/X11/ directory. It seems that this directory is no longer used as far as I can see. I assume this is also true on Kubuntu and Ubuntu as well as on my Lubuntu.
As I suggested in my last post, you can also try using xrandr to set the proper resolution: https://wiki.ubuntu.com/X/Config/Resolution
I am not very familiar with the KDE desktop. There must be some settings that you can adjust in KDE to set the proper resolution. How exactly have you tried setting the proper resolution on Kubuntu 11.10?
it's not a matter of setting my desktop resolution during my session in K
it's a matter of trying to get K to store this new resolution as my default
for each and every subsequent session.
there is an option within the control panel to save as default but this is
just a ruse as the display reverts to maximum resolution on the next session
This is the problem with all of this automatic (i.e., no xorg.conf needed) configuration. When it works, as it usually does with most graphics cards, it is great. However, when it does not work it can be difficult to override the automatic configuration to set things up the way you want them.
Have you managed to create an xorg.conf file while in recovery mode at all?
If you are still having trouble doing this, try booting to recovery mode and run X -configure. Then reboot to the desktop and run:
sudo cp /root/xorg.conf.new /etc/X11/xorg.conf
to copy the new xorg.conf to the /etc/X11/ directory. Then edit the xorg.conf file to your needs. Then reboot into (hopefully) your desired resolution.
If you have a known good xorg.conf file saved somewhere from a previous Ubuntu install, you could just use that and it would likely work. Or if you can find one on the internet somewhere, just use that and edit it to your needs.
Have you tried using xrandr as in the tutorial that I linked to? I'm not sure what else I can suggest.

If any of that effects the grub menu in anyway you have some very large problems indeed.
There is no mention of "update-grub" (a harmless command), "grub-install /dev/sdx" which could cause problems if you don't know the address of your drive. Nope, I don't think it will bother grub.
dpkg-reconfigure -a should make sure that the basic system is within the default rules for that system as seen by the package management tools. Basically are they installed right and some basic configuration.
It is just one of the dpkg commands that I use on package management problems. I like to run it early to see if it works. It has fixed things I didn't think it should. Unfortunately I doubt it will here but it will not hurt any thing.
Okay.. so I ran 'apt-get update' and 'apt-get upgrade' the system located and installed updates. I successfully rebooted, went into recovery mode and went through the same process as before and still got the same error..
