Resolution trouble

BopNiblets · 23-01-2010 03:46PM #1

Blargh, just booted into Mint there and my resolution popped back down to 640x480 from 1680x1050.
I checked the nvidia settings (Geforce 8800GTS, was working fine) and the resolution options were limited, not even 800x600.

Here's what I did:
-checked synaptic and saw xorg upgrade, marked all of them and upgraded, no problems
-dropped out into terminal and tried sudo dpkg reconfigure xserver-xorg (which I just discovered doesn't work in later Ubuntu versions and Mint obviously, d'oh)
It didn't actually do anything when I tried that but when I rebooted into recovery mode it came up, but then I couldn't get past the use default configuration, pressing OK would do nothing and only option was to go into low graphics mode.

Now, strangely when I booted into Windows 7, my res was down to 1024x768, but I was able to change that back to 1680x1050 easily.
So I'm thinking maybe the problem is with my gfx card or monitor, although neither are that old.
Also strangely, when I booted Mint off my LiveUSB it also went straight to low graphics mode, ze plot thickens.

Edit: here's my xorg.conf, looks pretty sparse

Try this:

nvidia-xconfig --mode=1680x1050

apt-get install nvidia-xconfig /*if it's not installed already(unlikely)*/

Make sure the xorg.conf file in /etc/X11 updated correctly, then just restart Xorg.
killall Xorg should do the trick.

Did you also happen to do a kernel upgrade? And did you manually install the nvidia driver? if so, the version of the nvidia driver may not be compatible with your current kernel, and you'll need to either upgrade nvidia drivers or boot off the older kernel.

Oh I forgot I tried deactivating and reactivating the nvidia drivers, v185 is the latest I get, and yes I think there was a kernel upgrade when I marked all upgrades in synaptic, thought it wouldn't hurt!

I'll try that stuff, thanks gents.

Edit: ok new xorg.conf, but still no resolution change or option to change after the killall Xorg command.

Check your /var/log/Xorg.0.log for errors (grep for EE) - I'd bet the nvidia kernel module isn't compatible with your new kernel - remember that the packages come from two different sets of people, so sometimes the nvidia drivers can lag behind the kernel (if the kernel release was very recent)

Try booting into the older kernel to see if the resolution looks ok there.

It doesn't, I booted into it, it went into the reconfigure setup, said it created a new configuration and to reboot, I did that and no change in resolution, bah.

Could it be my gfx card or monitor? Booted from Ubuntu 9.04 disc and it just went straight to low graphics mode, that's got to be a bad sign, right?
But it's ok in W7, confusing!

If your graphics card has a socket for extra power and it is not getting that power it will reconfigure itself ........ or at least that was my experience when I disturbed the supplementary power cable ......

Still stumped on this, tried the ubuntuforums but navigating other peoples troubles with different hardware than mine is confusing

Ubuntu/Mint from LiveCD/LiveUSB/installed, just won't detect that my graphics card or monitor supports 1680x1050, it sees that it's a GeForce 8800GTS, has the drivers installed and activated
I'm able to play MW2 and stuff in W7 so the gfx card is working, I have tried configuring my xorg.conf file, even tried the xrandr command but no go, just what the crap is going on?

Here's a bit of my /var/log/Xorg.0.log that could be relevant (??)

(WW) NVIDIA(0): No valid modes for "1680x1050"; removing.

This is the low graphics error I get when I boot from CD/USB:

Have you tried using the nvidia-settings utility?

Of course! First place I went to, resolution options are:
640x480
320x240

None of the reset or Detect Display buttons do anything that I can see, I can put a pan resolution in Advanced but then I'm panning across a 1680x1050 display in a little 640x480 window.
