Can't select 1920x1080 (monitor's native res)

Glad to see you are getting it going. Yes there is lots of confusing on the Nvidia and Ati. A lot I think is based on the distro it is installed on. Many vary a lot and can be confusing. The guide fairly good. I will point others to it asking for nvidia help.

Everything is going fine - except for a few things---

My first login with the newly installed nvidia-glx driver was fine - but for every one after that I was locked out of 1920x1080 and set to the lowest res possible (640x480).

So what did I do? I deleted every resolution setting except for 1920x1080, and now it is forced to use the monitor's native res.

Now the problem - Locking kubuntu out of every resolution except 1920x1080 broke the system settings->monitor and display application - and I now have a GAMMA PROBLEM, with no way to fix it (gamma is corrected in the same area).

I need to know how to use xorg.conf or some startup script to alter the gamma upon boot. I know there's an "xgamma" command but I have no idea how to use it or where to put it for it to be active on boot. Any ideas?



-if there is a way to remedy the problem by letting kubuntu access all the resolutions again, I'd rather go that way. For some reason kubuntu doesn't seem to natively support the 1920x1080 setting - or did the nvidia driver not set something in xorg.conf correctly? My display might not have been recognized as 16:9 (I don't know why)

To determine if its a driver issue with that very high resolution why don't you select 1600x900 to see if that has the same problem.

Results were....inconclusive with 1600x900.

I have found out that the nvidia config generated it's own backup file that is formatted somewhat differently (has modelines, but only 640x480 resolution is listed). I'm going to alter that one to see if I can get things to work correctly...

Success. With an entry of " Gamma 1.0 " under the "monitor" section, the gamma problems seem to have been fixed - for the moment. All resolutions except 1920x1080 are locked out.

I still don't think kubuntu is compatible with 1080p though. The monitor adjustment menu is "broken" again.

I don't think it's the driver, as it exhibited this same behavior of "braking" that menu when I added my 1920x1080 modeline with the "nv" driver (although I did not have to lock it out of every other resolution then)

Should I email whoever works with kubuntu/ubuntu about this? I mean, has anyone ever got 1920x1080@60hz (1080p) to work in Ubuntu with no menu/xorg.conf-torture problems? I know very few users actually use a 1080p display for their PC, so maybe they just didn't think to add support for it? SUSE didn't natively support 1080p either (although 16:10 resolutions were supported).

With SUSE, the menu was 'somewhat' broken, in that it listed the resolution as being 640x480 when it was actually at 1080p (kind of like hacking games to run in widescreen in windows)

When I tried FC6, 1080p appeared to work (but that was one of the only aspects of Zod that DID work)

My "broken menu" error message is as follows:

The module Monitor & Display could not be loaded


The diagnostics is:

Possible reasons:
An error occured during your last KDE upgrade leaving an orphaned control module
You have old third party modules lying around

Check these points carefully and try to remove the module mentioned in the error message.  If this fails, consider contacting your distributor or packager.

My xorg.conf configuration is as follows:

I don't know where this came from, it's leftover from the nvidia backup.

Actually, I don't think I like Ubuntu very much anyways - because getting anything that's not obtainable by "apt-get" to work is a nightmare.

Before blowing it away I would make copies of the config files. Good reference to use when trying other distros.

That's what the above post is for
