Resolution problem in Ubuntu 9.10

[Raonaq]

I have a configuration of:

Intel Pentium Dual Core 2.40 Ghz cpu
Intel DG31PR desktop board
2 GB adata DDR2 (800 BUS) ram
NVIDIA Ge-Force 8400 GS NX84GS series PCI express

It's the first time i was installing a linux. First I collected an extra hdd for the installation. I used the entire drive for ubuntu 9.10 installation. It installed without any problem except the special features were turned off. It was said that the special features and animations would start only if their is a sufficient graphics processor. I picked up a solution and from the hardware drivers option, installed the nvidia graphics card. Problem started when i restarted my pc. The resolution automatically changed into 800 X 600 px. I changed it to 1280X1024 (which is highest for my monitor). But when i restarted again, it again became 800X600 px. And it becomes like this everytime i restart. I'm a novice in linux. So somebody help me out of this problem. The solution has to be easy, otherwise i won't understand.

You need to install the proprietary nVidia driver. You can find and download it from Welcome to NVIDIA - World Leader in Visual Computing Technologies. You will have to install it with the x-windows turned off, in console mode. On Red Hat systems this is runlevel 3. I don't remember which runlevel is needed for Ubuntu to do this. In any case, once you change the runlevel, you reboot, login, and install the driver from the text console. Then you change the runlevel back to the normal mode and reboot again.

AFAIK, Hardware Driver option installs Nvidia Proprietary driver only.
It looks like Ubuntu is not configuring your Monitor correctly and using wrong Resolutions and Refresh Rates. Have you checked Monitor section in Display settings?

In case it doesn't work, post contents of /etc/X11/xorg.conf file here.

Hello there.

I have a similar problem in the sense of Im setting a resolution of 1152 x 864, and when I reboot it's back to "good olde" 800x600px.

My graphics card is a PNY Geforce gt240 1024mb PCIe, which I have no idea how high a resolution it can go as I havent tested it under Windows. My monitor is a Iivama ProLite E430T (I know, horrible! ), but I do know that the monitor is capable of 1280 x 1024 @ 60Hz, which I have had working on Ubuntu and in Windows.

OS wise Im running Ubuntu 9.10 (originally it was 8.10 but had to do upgrade after upgrade just to get the nvida driver )

Now I must confess I do not know that much about Ubuntu. I did have a problem with this monitor pretty much doing the same thing (ie not selecting/getting the correct resolution) which was down to the xorg.conf file when I was using 8.10, but back then I was using a different computer. I have tried editing the xorg.conf file with my current problem and it has not changed it.

However, after a google searching for solutions, I have found out which files to read, and from what I can gather from the xorg.0.log that it is reading the xorg.conf fine, but near the end of that log, it is setting two resolutions:

(**) HID 062a:0000: (accel) set acceleration profile 0
(II) HID 062a:0000: initialized for relative axes.
(II) NVIDIA(0): Setting mode "800x600"
(II) NVIDIA(0): Setting mode "CRT-1:1152x864@1152x864+0+0"
(II) NVIDIA(0): Setting mode "800x600"
(II) NVIDIA(0): Setting mode "CRT-1:1152x864@1152x864+0+0"

Can anyone here help please?

Could you post the contents of xorg.conf file here?

Sure, but as Ive said: I dont think the problem is with the xorg.conf file, so I have included the xorg.0.log.

HorizSync 28.0 - 55.0
VertRefresh 43.0 - 72.0

Are above Refresh Rates supported by your Monitor? Check Monitor's Manual.

i made changes to the xorg.conf file, but can't change it. and also, i can't open the ubuntu display page where a message: "Your hardware do not support the display settings. Do you want to open your graphics driver configuration settings instead?".

Right, let me make one thing very clear: if my monitor doesnt support it I get a message on my screen saying out of sync and I cannot see a dam thing. The monitor is second hand and when I got it didnt have any instructions with it (as you would expect with second hand monitors) Since Im using that refresh rate I should imagine it is supported as I can still see everything and no sign of the message I get when it isnt supported.

Changed file to the above, rebooted, and no change whatsoever (as I expected). Not even showing the 1280x1024 in the options.

Might even have another tinker with that file but again I dont expect that to work either

Let me make one thing very clear to you too. Resolution depends on Refresh Rates only and if Refresh Rate range is too low, there is no way to achieve desired Resolutions. Lower range doesn't throw out of sync error message.

Most of old Monitors have Refresh Rates range around 30 - 71 HorizSync and 50 - 160 VertRefresh.
