Cannot set screen resolution [solved]

[banjo]

I am trying to use the MCC to set the screen resolution on my monitor.

 

I ran the MCC, went to Hardware => Change your screen resolution

 

The program waited for a few seconds and then popped up a Warning

dialog that said "This program has exited abnormally".

 

No error messages.

 

Anybody know the name of the program so that I can run it in a

terminal and see what errors are coming out? Or perhaps where

the error messages might be saved? I have no idea why this quit

working. None of the hardware has changed since I installed the

system two years ago.

 

Mandy 9.1 Nvidia graphics card & drivers.

 

Thanx in advance

Hi Banjo.

I think you need to reinstall your Video driver, it has probably s**t itself.

It could be a sign that your video card is on the way out and done something funny with the driver thus corrupting it.

Maybe just a driver reinstall will fix things though.

 

Cheers. John

John,

 

Thanks for the info. As a matter of fact, I just remembered that we did upgrade

the Nvidia driver a few months ago to get a program to work. I wonder if there

is now some incompatibility with the MCC.

 

Maybe we need yet another upgrade. I will look into it.

 

Anybody know what program the MCC runs to do this work?

I really don't like wizards. They make everything "invisible",

which is fine until it no longer works.

It runs XFdrake, which edits /etc/X11/XF86Config-4 (on your version of MDK).

adamw,

 

Thanks for the info.

 

I am familiar with the file, but not the program.

I will see if I can trouble-shoot it. Perhaps the file itself is

not precisely correct (although the X system is running fine)

Edit: OK here is where it gets weird. I made a backup copy of

XF86Config-4 just to cya (in case I really screw things up)

and cd to /etc/X11 and run XFdrake as root.

 

It runs fine.

 

Go figure.

OK this just keeps getting weirder.

 

I went back to the MCC again to see if I could run the program

from there (after a few reboots.... unrelated) and I ran the program

labeled "Change your screen resolution" and it just crashed.

 

Then, as I was about to quit, I noticed that an icon for XFdrake

sits right next to it. So I ran that, and it works........ and it lets me

set the screen resolution. That, obviously, is the same program that

I have been running from the command line.

 

Now I am wondering what that other program is and what it

is for and why it crashes.... and why there are two of them there

that do the same thing. But I guess it isn't really important because

the XFdrake seems to work and do what I need.

 

Thanks to all the fine (patient) people on this board for helping

me figure this one out.

Oh, I think that is probably for doing resolution changes _on the fly_ (i.e. without starting X). I don't remember that functionality was already around in 9.1, though...
