nvidia drivers?

bocochoco · 10-02-2007, 09:07 PM

I dont know if I've installed them properly... I think that I did though.

Code:

sudo killall gdm
sudo aptitude update && sudo aptitude install nvidia-glx
sudo nvidia-xconfig

that is what I used to install the drivers. They seem to be working fine. However, I can't get my monitor into its native resolution of 1680x1050. I tried changing the xorg.conf file and reloading the X server, but it doesnt work. My xorg.conf is below.

Code:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 1.0  (buildmeister@builder26)  Thu Nov  9 17:55:59 PST 2006

Any ideas on what I did wrong, or how to make it work properly?

Thanks a lot

You aren't using the "nvidia" driver.

Code:

Section "Device"
    Identifier     "nVidia Corporation G70 [GeForce 7600 GT]"

    Driver         "nv"
EndSection

Also, the resolution you mentioned seems like a bit of an oddball. You may need to use the gtf program to generate a custom mode line.

Example (use the values from entering in the command yourself)

Code:

gtf 1680 1050 60 -x
  # 1680x1050 @ 56.00 Hz (GTF) hsync: 60.70 kHz; pclk: 135.98 MHz
  Modeline "1680x1050_56.00"  135.98  1680 1784 1960 2240  1050 1051 1054 1084  -HSync +Vsync

Change the lines to:

Code:

  # 1680x1050 @ 56.00 Hz (GTF) hsync: 60.70 kHz; pclk: 135.98 MHz
  Modeline "1680x1050_56"  135.98  1680 1784 1960 2240  1050 1051 1054 1084  -HSync +Vsync

And add them to the Monitor section:

Code:

Section "Monitor"
    Identifier     "Generic Monitor"
    HorizSync       28.0 - 51.0
    VertRefresh     43.0 - 60.0
    Option         "DPMS"
    # 1680x1050 @ 56.00 Hz (GTF) hsync: 60.70 kHz; pclk: 135.98 MHz
    Modeline "1680x1050_56"  135.98  1680 1784 1960 2240  1050 1051 1054 1084  -HSync +Vsync
EndSection

Then edit your modes:

Code:

Section "Screen"
    Identifier     "Default Screen"
    Device         "nVidia Corporation G70 [GeForce 7600 GT]"
    Monitor        "Generic Monitor"
    DefaultDepth    24
    SubSection     "Display"
        Depth       1
        Modes      "1680x1050_56" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       4
        Modes      "1680x1050_56" "1024x768" "800x600" "640x480"
    EndSubSection
    ...

The gtf program comes with the X11 installation. Please read the gtf and xorg.conf manpages for more details.
It would also be a good idea to look at your xorg.log. There may be error messages (they start with (EE) ) indicated when the server tries out the 1680x1050 resolution.

Despite the fact that the 'Driver' line in the config file still read 'nv' , would one of you two please tell me which driver this procedure actually 'Apt-got'? Did it actually install the real 'nvidia' driver and simply neglect to change the Driver line?
If so, Is this the {best|worst|right|only} way to install the real 'nvidia' driver on Ubuntu?

Thanks.

Actually... it did change the driver to nvidia. Someone, somewhere suggested to change it to nv. What is all that modeline stuffs? And 1680x1050 is a standard 16:10 widescreen resolution. The monitor I have is http://www.sceptre.com/Products/LCD/...x20wg_Naga.htm

jschiwal · 10-03-2007, 06:34 AM

When I installed SuSE 10.0 on my Laptop with a 1280x800 screen, I had to use gtf. Starting with 10.1, my LCD laptop monitor was supported. Try it out first without a custom modeline. If it doesn't work and the xorg.log indicates that that resolution was rejected, then you can try it with a custom modeline.

hairysocks · 10-03-2007, 07:20 AM

You haven't mentioned which nvidia card you are using. I have a GForce 2, and I had to use the nvidia-legacy driver rather than the nvidia driver.

..'Modelines' are pre-calculated resolutions that the X server can/will try to use to drive your monitor.

The Modeline contains all the necessary data for you X server to send a signal to the monitor that the monitor will actually 'like'.

I could be slightly wrong here, but: I *think* they are most useful for creating "weird" resolutions and/or odd aspect ratios.
Personally, Ihave never used a Modeline in any of my configurations. I have always used the 'regular' method of eg., Modes "1024x768" "..blah" ".blah" and let the monitor sort out its own H and V sync/scan rates.

I have two GeForce 7600GT in SLI in my box. WIth the Driver "nv" setting glxgears gives me ~11k fps. I tried adding "1680x1050" to the Modes section under each color depth level but it didn't let me change to it. In the past I got it to work somehow, but this was before it was xorg.conf.. now things seem different. I am most surprised that ubuntu doesn't have some sort of built in thing to let me set the resolution. There is a thing listed under system preferences "Change Screen Resolution" but it only goes up to 1024x768. What is this gtf thingie you are talking about?

Tell me something, as I also have an SLI board, though I don't plan to use SLI "mode" but rather two cards separately:

Are you running the two cards in bridged SLI mode under Linux? Or have you NOT got them bridged..?

If bridged, could you post your output of 'lspci' from a root console? I'm curious. Thanks!

And -- you ARE running Ubuntu, yes?

bocochoco · 10-03-2007, 11:50 AM

Yes, I am running ubuntu 7.04. The two cards are bridged together and work properly in SLI under windows. I am trying to get it to work this way under linux if possible. I am at work right now, so I will post the output of lspci when I get home tonight.

GrapefruiTgirl · 10-03-2007, 11:58 AM

Ok great, thanks. I am curious because I don't know if/what/how anything exists or implemented for using actual SLI bridged mode with Linux. I just plain don't know.

And, gtf is a tool used to generate modelines for the desired resolution.
