monitor not being detected

[elmerstudd]

My display is stuck on 640x480 resolution and I would love to be able to switch it to the larger resolution that I can handle in Windows and could handle in a previous install of Kubuntu.

My monitor is an Acer AL2216W
I installed the 180.44 Nvidia driver for my Geforce GTS 250 video card. Nvidia X Server Settings recognizes both the card and the driver.
Under "Display Configuration" it says my display model is "DFP-0 on GPU-0" which means nothing to me and there are no other options available to be selected.

Previously I have used envyng to get drivers, but this time Kubuntu's "Hardware Drivers" seemed to properly install 180.44 so I used it instead.

How might I be able to fix this? I appreciate any help in advance.

[EDIT] While trying to install, errors occured until I turned safe graphics on for the installation. If that is related I hope it inspires a solution.

Well, yes.

You may want to make some trivial change from the Nvidia Control Panel (whatever it is called), and save it. Then have a normal reboot.

If this doesn't fix it, you can try now to run the "fix graphics" option when you boot in Rescue Mode.

Hopefully the one or the other will fix things.

Re: monitor not being detected

yeah, enter:

sudo nvidia-settings

in the konsole, and change the resolution. See if that helps.

Yeah, I had to do that. Otherwise, when you try to save your settings to xorg.conf, it won't work, because the app doesn't have permission to change a system config file.

Isn't there some way one can set up a menu icon to run an app with "sudo" automagically? I realize I'd still have to put in my password, but I'm tired of always having to open a terminal window to make any changes to the display settings. I've tried editing the command on the K menu to invoke "sudo nvidia-settings" instead of plain "nvidia-settings," but it doesn't work. The Nvidia control panel never launches.

Yep, you drag the menu entry to the plasma background, so now you have an icon. Tou right click on it, "Icon Settings -> Application -> Command", and add sudo. This will only work for the idon on the desktop, but it's better than nothing. If it doesn't work fine, you can go to Advanced and make it run on a terminal, so you can see error messages ...

Re: monitor not being detected

I was going to post to create a .desktop file...same basic solution...I'm thinking that sudo should be changed to kdesudo, to be safe though. I should have stated that in the original post, but mis-typed it.

Re: monitor not being detected

Yes, yes, it should be kdesudo! And yes, it is the same solution but I always prefer the easy way, especially when recommending things in a Forum (otherwise, it looks like we are in the stone age as compared to other operating systems )
