Resolution/Aspect Ratio settings


I cannot for the life of me figure out how to get my new Suse 10.1 installation to recognize that my display has a 16:9 aspect ratio with a resolution of 1920x1080.

I downloaded updates from nvidia and got them installed, but they don't seem to do anything. I'm stuck at 1280x1024.

I'm really starting to lose patience with this OS.

Does anyone know how I can fix this?

Did you try running the "nvidia-settings" program and have it autodetect your monitor?

If it is done the same as it is done in FC, you will need to post your xorg.conf.

Where do you find that program? I know my way backwards and forwards around windows, but I'm totally new to linux. Please excuse my noobishness.

You should run sax2 from the command line:

ctrl + alt + backspace
sign in as root
type sax2
now you should be able to make adjustments: when sax comes up with a proposal straightaway (it should show a blueish screen) you should refuse to accept; then you can select the proper values.

Btw, you should have done this right after the driver was installed, so I can't guarantee the method is fireproof.

There was a menu for configuring upon installation, but 16:9 was not available, only 16:10.

Bring up a terminal and type nvidia-settings. Go to X Server Display Configuration. Look at the Resolutions available. There is also an auto resolution.

OK, I checked and those exact values aren't available from the menu.

If you really need these, I think the only option left is to set them manually by editing xorg.conf in the /etc/X11 directory. Have a look at it and try to determine whether it specifies any values over 1280x1024 or not.

Edit: I just see Quakeboy inserted a post while I was typing this up. I would say, try that one first, since it's more nvidia specific; mine is rather a generic approach and a last resort sort of thing.

Thanks, but it looks like I inadvertently screwed up my xorg.conf file, so now the GUI won't even start up. Unless anyone knows a way to restore it to its original form from GUI-less Linux (or from 64-bit windows), I'll have to nuke the linux partition and start over.

omg, you should never ever touch any crucial file without making a back-up first. Well, it's too late now.

I suggest your reboot and add any of these as an additional boot paramater:
single, 1, 3
Then you boot.
You'll end up in a terminal where you need to specify username ("root") and password (root password); next type sax2 and do your best to build a new xorg.conf.

So what would be the point of exploring your linux under Windows? Exploring is not correcting; and on top of that I'm pretty sure that it's either impossible to write from Windows to Linux or that it is going create only more trouble.

I smell disaster in the air.

Run sax2 like jay73 suggested. There is nothing you can do from a Microsoft boot.

One other option is to check to see if there are any xorg.conf backups in /etc/X11. But, really, if you're going to just do things at random, there's not a lot we can do for you.

1. See if you have gtf on your system. If not it should be available from your packet manager.

2. In this example I will generate a modline for 1440 X 900 @ 60

[fred@127 ~]$ gtf 1440 900 60

# 1440x900 @ 60.00 Hz (GTF) hsync: 55.92 kHz; pclk: 106.47 MHz
Modeline "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync

3. Insert the generated modline in the section similar to this:

Section "Monitor"
#HorizSync 31.5 - 100.0
#VertRefresh 56.0 - 75.0
Identifier "Monitor0"
VendorName "Unknown"
ModelName "Unknown"
ModeLine "1440x900_75" 136.8 1440 1536 1688 1936 900 901 904 940 -hsync +vsync
ModeLine "1440x900_60" 106.5 1440 1520 1672 1904 900 901 904 932 -hsync +vsync
Option "DPMS"
EndSection


4. Add your resolutions similar to this:

SubSection "Display"
Depth 24
Modes "1440x900_75"
EndSubSection

5. Save xorg.conf

restart xserver
