Resolution problem with nvidia driver.

[myme]

I'm experiencing a problem with the screen resolution while running the nvidia driver. Currently I have the 185 beta driver installed. I had the same problems with the stable one, but wanted to check if the problem persisted with the beta driver.

The problem is basically that the screen seems to be 'zoomed' in a way towards the center, meaning the edges of the screen are not displayed (including panels). When I delete/rename my xorg.conf file and start gdm without it, the screen is OK, but then the vesa driver is used and not the nvidia driver. I need to be using the nvidia driver for development reasons.

The monitor model is ViewSonic VX2435wm 24".

Check if your monitor supports 1920x1200, if it doesn't change

Modes "1920x1200" "1680x1050" "1440x900" "1280x960"
to

Modes "1680x1050" "1440x900" "1280x960"
in the 2nd last line

It supports 1920x1200... That's also the resolution it has when not running the nvidia driver.

[miegiel]

I've got no experience with the nvidia drivers, sorry. The only thin I can think of is changing to a lower resolution and putting it back to 1920x1200 again. Did you check your monitor OSD menu to see what resolution it's using and if it's the same as the resolution set in ubuntu?

[andrea000]

have you tried envyng to install your driver it should tell
you what driver is recommended for your card.Then go to nvidia
x sever setting and set the resolution and save it back to
your xorg file.

hi, iv been looking through the forums and cant find anywhere better to post this issue, and would rather not create a whole new thread as im sure there are plenty on dual monitor resolution issues out there, just none of them seem to address my issue.

im runing ubuntu 8.10 on my desktop
graphics card is the 250GTS from Nvidia.
have 2 polyview 17" monitors. one VGA, the other DMI both plugged into graphics card

now i installed the drivers and that was all working fine.
set up the 2nd monitor and had the issue of the VGA only running at 1024x768 natively, however as in windows 7 i was running both monitors at 1280x1024 i know it is capable of that resolution.

my question is A) how do i get it to run this?
and B) what information do i need to provide. have not used ubuntu in months and so am very rusty on commands.

so what commands will i need to run to give print out of the resolution setup?

cheers.

usually you print all the available resolutions by doing the foll: at the command prompt...

$ xrandr

if the resolution, 1280x1024 is listed, do

$xrandr -s 1280x1024


this should work...

if it does not, go to system > administration > nvidia x server settings
you can change the resolution there...

hope it works..! cheers!! :-)

[Cain67]

not to sound to retarded, but it didnt work.
iv run the Nvidia x server settings, and it gives odd options for the VGA monitor.

CRT-0 resolutions : 1360x768, 1152x864, 1028x768
however the CM0 CMC 17" AD resolution supports the 1280x1024 im looking for

the monitors both run 1280x1024 in windows 7 with no issues.

that there is the xorg.conf file, and has more info on the graphics card.
had a similar problem in windows xp, and never managed to fix it.
is there anyway to force a resolution on the monitor???

further help will be greatly appreciated
cheers
