My turn for screen resolution issues

mitchell7man · 06-01-2007, 10:43 PM

Hello, i opened the xorg.conf file, and added the resolution i wanted 1280x1024 but when i activate it the screen turns into a pile of squares. My video card does support it as in my windows partition it is running at the described resolution. Here is my xorg.conf file.

Did i add it correctly? all i did was add "1280x1024" to the modes sections. What else do i need to do etc? thanks in advance...

This may sound dumb and you may have tried it but try using the nvidia settings manager instead of the xorg file.

mitchell7man · 06-01-2007, 11:56 PM

What is / were do i get nvidia settings manager?

Verify the HorizSync and VertRefresh values - if you set them too low, you may not be able to get the maximum resolutions (but if you set them too high, you'll get a black screen!). Check your manual or the internet for the minimum and maximum refresh rates of your specific monitor.

davimint · 06-02-2007, 05:26 PM

Run this from within a x-enviroment

Code:

bash-3.1# nvidia-settings

It's a little tricky at first but ok after that.

Although I agree with "jay73" that the this part of the config looks a little off for 1280x1024

Code:

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 28.0 - 51.0
VertRefresh 43.0 - 60.0
Option "DPMS"
EndSection

let us know.

What do you mean by running it inside of a x environment? I don't have the problem as of now b/c i reinstalled the noob thing i do... but for the future i am still interested, as to how this all works out... also right now the resolution i have is the one i wanted, but it is at 74hz not 60hz as is recommended so I would still like to fix that, and again i am still a relative noob, i can get around, have found what i like in linux etc. but I don't know everything... as this post and thread reveal

but that's why I want to learn.... anyway to quit jabbering, apparently i still want to change the refresh rate, so what exactly do i need to do to do that?
BTW- What set me over the edge to reinstall was when i quit getting borders on my screen. Probably a beryl issue. - not just the screen resolution problem

mitchell7man,
I'm a newbie too, so I mostly learn by error, most of the time resulting in the same as i've reinstalled my system so many many times. Looking at your post count and if your not yanking my chain, here is what I meant.
I think the nvidia-settings command can be call outside of the x-environment as in the console without x11 running. But the reason that I stated it like I did was that it's a good & nice gui interface so I always use it while inside a gui environment. Now all that being said, there's another problem that comes to mind about the nvidia-settings manager. Since I use slackware and dabble in other distributions of linux i'm not sure how ubunta is installing the nvidia driver. The reason I said that was that the other day I installed debian and there was two ways to install nvidia driver so the nvidia-settings command may not even work.
Now, to explain about the HorizSync & VertRefresh rates your asking probably more than I know other than from what I've played with. What I meant by my statement was that they both looked on the low side, I think mine is set at HorizSync 31-50 and VertRefresh at 40-90 but again that depends on your monitor.

mitchell7man · 06-02-2007, 10:35 PM

Ok, thanks for the understanding

... I guess i will just have to look more into my monitor specs... its kind of cool that someone else understands the whole learning by trial and error, and ending up reinstalling anyway thanks...
