[ubuntu] How to fix low resolution with xorg.conf

http://ubuntuforums.org – I just got my dual screen set up in ubuntu using an nvidia GeForce 8400 GS video card. The nice thing is that it worked as an extended desktop right away. But the resolutions available are wrong. They are not as high as the monitor can go (1440x900), and they are not the right aspect ratio either. I didn't have any luck adding new modes with xrandr commands. It would refuse them as if my hardware wouldn't support modelines for higher res. Anyway, I'd rather achieve this by editing xorg.conf so the change will persist. I've tried about a dozen permutations of xorg.conf files based o (Hardware)

I have figured out how to set my resolutions via xrandr but how do I set them statically via xorg.conf so I don't have to keep readjusting my wallpaper and resolutions?I currently use these commands from xrandr.DVI-0 --output DVI-0 --mode 1600x900 --left-of VGA-0 VGA-0 --output VGA-0 --mode 1440x900 --right-of DVI-0

I have an TV screen which I would like to attach to my laptop with the right resolution. Just because this is basic stuff I searched and found a lot about the xorg.conf file, modelines and so on.

My Screen has a resolution of 1920 to 1080 pixels and I created this xorg.conf

But in the nvidia settings no trace of this resolution appears.

What is wrong about this? Any Ideas?

I guess I'm not a total beginner to Ubuntu, but when it comes to XORG I feel like I am.

I have two monitors, monitor 1 has a resolution of 1440x900, monitor 2 has a resolution of 1600x900.

Monitor isn't being detected 1 year 16 weeks ago

Hey guys i'm having a problem with my monitor.. I just installed ubuntu 11.10 and the monitor appears to be unknown with a resolution of 800x600.. When I install the discrete graphics card driver ATI the system reboots and now the monitor won't even turn up because of wrong refresh rates =\ My question is.. Is there a way to force a resolution without the xrandr commands?

Hello forum,

I have Kubuntu 9.10 running on a Dell Vostro 1720 with 17" display with a resolution of 1920x1200. The graphics card is a GeForce 9600M GS and I am using the nvidia driver for it. At 1920x1200 everything works really well, my problem is that I can't change to a lower resolution. I've tried adding new resolutions in xorg.conf,

I have previously change xorg.conf files to adjust my screen location, but I am stuck with 800x600 or 1024x800 and no other resolutions

lspci | grep vga detects the card but I do not get the resolutions that should be associated with the card.

I have been unable to adjust the video card on my xserver on 12.04.

Hello,

I was wondering if anyone could help me fix the resolution for my Samsung SyncMaster 941BW second monitor (along with my laptop monitor).

I've had the resolution working fine with previous versions of ubuntu (at 1440x900) but since I've updated, the xorg.conf file no longer provides the right resolutions. I had the orginal xorg.conf file, but somehow got rid of it.

Hi,

I've been trying to get my screen resolution to display correctly for the past few days. I've read many solutions but none have worked for me yet, so I thought I'd reach out for some help.

I have 2 acer monitors, both having a resolution of 1440x900 (specs http://www.newegg.com/Product/Produc...82E16824009235)

I have an nvidia GeForce 8400 GS graphics card.

Initially X does not use xorg.conf. So suppose I have a certain monitor installed with the system, then X will be set in accordance to that monitor.

If I change the monitor after a reboot, what problems will I face?...will X work properly? How does X handle this situation?
