Adjust the screen position / size, nvidia, fedora 10
 

Fedora 10 KDE

How can I adjust the screen position a little to the left?

I have a KVM and the other pc is just fine.

I'm running NVidia 5300. My settings only allow for rotation and resolution.

The KDE info center shows I have a NV34 5200 card, but doesn't show what driver is being used for it.

Doesn't your monitor handle this, and not your graphics card?

If what I want to do is not possible in Linux, pls just say so.

Yes, actually it does. Can't remember the last time I saw one that didn't.

As a matter of fact, it's not possible in Linux... or Windows, OS-X, OS/2, MS-DOS, CP/M, Unix, or any other OS I've used. The size/position controls are on the monitor.

Windows does
 

I've been able to adjust the video position in windows for 10 years or more... A quick GIS found this. http://webpages.charter.net/lhaas994...ion%20size.JPG

I'm guessing linux drivers are not capable of this.... yet....?

Does anyone know about this?

For those who replied, pls read again: I have a KVM (multiple computers on one monitor).

Must be an nVidia thing. If you're not sure what driver you have, it's probably the "generic" driver. nVidia does supply advanced drivers for their cards/chips to run on Linux. Go here for the free download.

The nvidia installer
 

Thanks I'll try that.

The following assumption: we're talking about the X server (graphics), not a console (text mode).

I'm sure you can do it. I did it once but I can't remember the videocard (nVidia or Matrox) and monitor (probably an Iiyama) that I used then.

What I remember:
you need to use a modeline for the resolution that you use. Next you can finetune the horizontal timing parameters. Do this with care and in small steps.

Maybe http://www.arachnoid.com/modelines/ can be off help.

Note that you might have to switch 'edid' off so the driver ignores that monitor information; see the man page for the X-server configuration.

Generally, if you've installed the nvidia drivers (see www.rpmfusion.org for how to set up the repo, then install the relevant kmod-nvidia with whichever package installer you prefer), the issue will be solved by setting the refresh rate correctly.

I know for example, that for my displays, it insists on defaulting to 60hz, and this will be about 5mm too far right. When I set it to 75, it's fine.

Note that to save the settings, you will need to run nvidia-settings as root, so open a terminal, "su -" and enter root's password, then "nvidia-settings".

Note that you probably need to reboot between installing the package and running the setup.

You're right that refresh rates can be the cause and the easiest solution, but ...

I had a dual boot system (WinXP and Slackware). The position would be OK in Windows and not in Slackware and vice versa (at the same vertical refresh rate). Setting up and configuring a modeline in Slackware solved that issue.

Conclusion: refresh rate is not the main cause but the 'default' settings (or the calculations) that are used by a driver for that refresh rate are.

Thanks for the info.

I used the monitor adjustment for linux, then corrected XP with the driver controls.

This is the easiest solution, I'd still like to see more control in Linux :)

I realize this thread is quite old, but the solution that solved the issue for the OP was, IMO, unsatisfactory so I wanted to post (or quote) the solution that worked for me.

I had the exact issue as the OP: KVM switching between 2 PCs, but 1 had Mint 10 installed and the other Debian 6 stable. The Debian PC had the screen displaced to the left, while the Ubuntu machine was unaffected.

Editing the modeline (which I had in there anyway in order to select the monitor's correct resolution/refresh rate) in xorg.conf is what solved this.

So a delayed thanks to Wim Sturkenboom for providing the link.

:)

And a delayed it's a pleasure for the thanks ;)
