    force screen resolution?

    comp too old to mention, dualboot XP/kubuntu 9.10, 1GB ram, nVidia 6200 (185 driver) with generic screen.

    ever since the upgrade to 9.10 kubuntu changes my resolution upon system start just about every time i start up the computer. it chooses between two resolutions: 1280x1024 (the one i want) and 1024x768 (without any higher res available). when i get the lower resolution i have to restart the whole computer a few times until it recognises the higher resolution.
    how can i force a screen resolution? is there any parameter i can put into one of the configuration files or into grub? any way i can force screen resolution and refresh rates per program? (can't run Diablo 2 on kubuntu, screen shuts down).

    Re: force screen resolution?

    If you have an Nvidia driver do you have Nvidia XServer Settings in your menu? Does that not have the change of size you require? If you go >Xserver Display Configuration>(Display) Resolution.

    You make it "stick" by opening the Nvidia Xserver Settings from a Terminal with the instruction:
    kdesudo nvidia-settings

        Re: force screen resolution?

        thanks! why haven't i thought about that? i'll leave this thread open for a couple of days and see if it works or not. if it works i'll [SOLVED] it.
        still, something weird happened. as i clicked on "write configuration to xorg.conf" i got this message after which nvidia settings window crashed:
        Code:
        Failed to parse existing X config file '/etc/X11/xorg.conf'!

          if its a newer install there in not always an /etc/X11/xorg.conf file by default , if you create one (even blank) when you save w/ the nvidia-settings program it will save your config (kdesudo before the command)

            well, after one startup the resolution is still 1280x1024 but it doesn't say anything actually. i just checked nvidia x server settings and it went back to "defult", so the setting wasn't saved after the reboot. plus, i checked and there IS xorg.conf. this is all that is in the file:
            Code:
            Section "Screen"
	Identifier	"Default Screen"
	DefaultDepth	24
EndSection

Section "Module"
	Load	"glx"
EndSection

Section "Device"
	Identifier	"Default Device"
	Driver	"nvidia"
	Option	"NoLogo"	"True"
EndSection
            maybe it's a premission problem? maybe i should load the nvidia x server settings window through kdesudo? if so, what's the command / file name?

              yes you must run nvidia-settings as root if you plan to save it
              [code=run in konsole /run box] kdesudo nvidia-settings [/code]

                  Code:
                  have you created (as root) the xorg.conf file? that should remove your error. even if its blank (just be sure to open nvidia-setting first. then create the file and adjust then save)

                    i haven't created the file, the system created it when i installed it a few weeks ago. should i REALLY delete it and create it as root??

                      not if its already there...
                      perhaps this page will help you manually add the display res.

                        So far you have not posted an xorg.conf file that's going to force the resolution. It's always a pain to create xorg.conf files but not that difficult. You need to create a Monitor section in your xorg.conf file with a modeline for 1280x1024. These problems occur with old video cards or obscure monitors that don't report their capabilities properly to HAL. I had to hack mine again in 9.10 to get dual monitors working correctly.

                          this might be a bit more useful , its xorg.conf from my server, that does not have a monitor, so i had to manually add mode lines for resolution since after i upgraded to KK it doesn't want to display in 1024x768. Since i prefer a res of 1024x768 for my VNC use i had to manually set it,

                          sorry it does not contain a mode line for 1280x1024, but you would just have to add one to use it,

                          NOTE: this machine's video card is a Geforce2 MX (32mb ram i think) using the NVidia 96 driver.

                            Re: force screen resolution?

                            That's a lot more than you need and will probably cause you more grief if you don't know what you are doing. I'll start with the xorg.conf you pasted. To create a mode line use the command-line program cvt (/usr/bin/cvt). Look at the man page (very short) for a description. To create a mode line, you need the horizontal and vertical resolution plus the refresh rate. Typically for an LCD the value is 60hz. To create a mode line for an LCD panel capable of 1280x1024@60hz...

                            Code:
                            cvt -r 1280 1024 60
                            ...you need to copy the mode line to your xorg.conf file. You will need a few additional lines in your Monitor section in addition to the mode line. Look to sithlord's post or the man page for the additional lines. Add a Display subsection to the Screen section, add your mode line name (what is between the double quotes) and it should work.

                            Code:
                            Section "Monitor"
  ...
  Modeline "1280x1024"  <paste the output of the cvt command>
  ...
