Resolution with Syncmaster 940BW
I can't seem to get my Samsung SyncMaster 940BW to get proper resolutions (1440*900). My current max is 1024*768. I can't figure out how to adjust it from the already installed programs, and my searches haven't given me any hints either.
I'm running Ubuntu 6.06. Thanks, Sherwood |
Which video card are you using?
Either the monitor is not recognized in which case conservative settings are specified for the horizontal sync and vertical refresh or the video card driver needs a bit of configuring. For the first issue, you can check horizsync and vertrefresh in the config file against the specs of your monitor. I could only find 81 kHz as the max horizsync and 75 Hz as the max vertrefresh. Please post the sections device, monitor and screen of your X configuration file (usually located in /etc/X11 or similar) if you need more help. |
Hmm, I couldn't make much of that out (first week of linux use), so I might need a bit of help decoding that.
Sorry about missing the graphics card bit, just slipped my mind. I run an MSI GeForce 4Ti 4200 8x I thought I'd take a shot at reinstalling the drivers and see how that went, problem is I'm still not familiar with alot of terminal commands, and execution, and apparently I need to do the following: Quote:
a) I don't know HOW to do those things b) I'm not sure I feel safe enough doing those things even if I had the command line knowledge. So I could use a hand puzzling through, and isolate and limit risks. Thanks again, Sherwood |
Please post the sections as asked for in my previous post and we will help you decode it and advise on the changes. From there we will take it further. It might not be necessary to (re-)install drivers.
If you insist on 'shuttting down the X server', the following can do it. Some notes first. You're going to modify the file 'inittab' and you need root permissions for that. In ubuntu this is achieved by prceedinbg a command with the word 'sudo'. Further I'm only familiar with vi, so I have to push that down your throat. You might want to use nano or pico that might be less powerfull but more user friendly. All stuff is case sensitive (quite common in the unix world), so make sure that <capslock> is off. Further I use the notation like <ctrl>. These are special keys (in this case the control key).
before doing the last step above, verify that your lines now look like Code:
#id:3:initdefault: Do the rest of your business and restore the original inittab afterwards.
before doing the last step above, verify that your lines now look like Code:
id:3:initdefault: Some notes on vi: vi can run in two modes, a command mode and an edit mode. When you start it, it will be in command mode. You can always get back to command mode by pressing <ESC>. To go to edit mode, you can press e.g. 'i' for insert, 'o' to start a new line after the current one, 'O' to start a new line before the current one and 'R' to replace a number of characters. As said, <ESC> will take you back to command mode. The official keys to navigate though a file (in command mode) are 'h','j','k' and 'l' but most of the times the cursor keys will also work. When in command mode, you can press ':' (colon). You're taken to the bottom of the screen where you can enter other commands (like 'wq'). 'w' will write, 'q' will quit, 'q!' (q followed by exclamation mark) will quit without saving the changes since the last write. |
Alright, as I stated before, I wasn't clear on what you were telling me to do in the initial X config situation.
I've investigated that, and found a negative on the config file. According to my sources (read: I used google) it should be "/etc/X11/XF86Config" but that file doesn't exist, only the directory "/etc/X11/" If you could give me a hand figuring out where that config file would be, I'd be glad to tell you the contents of the Devince, Monitor and Screen sections of it. I'll try and hold off on the driver install until after I try and get this running. |
There are two 'systems'. Older ubuntu versions use XF86Config-4.
If there is not something called XF86....conf, check for a file called xorg.conf . In both case, the files should be in /etc/X11; so analyse the contents of that directory. |

There are all three Device, Monitor, and Screen respectively. It was the xorg file, thank you for letting me know that. |
As far as I can see, there are a few things that need to change.
If HorizSync is not correct (too low), the system will not be able to use the max resolutions. Code:
HorizSync 28-81 Your system uses a default depth of 24, so add the required resolutions in that subsection. Code:
SubSection "Display" The used nv driver (see section device) is a generic driver for nvidia cards. It is possible that the generic driver does not support 1440x900 and that the above advised changes will not have an effect because of that. If you're happy with the options of this driver, you don't have to change it. Although I'm not familiar with your card, I think that the 'official' nVidia drivers support your card as well (if not, they will tell you when you install the drivers). Installing the drivers might be tricky on Ubuntu as certain files are needed and I'm not sure if they are supplied with Ubuntu. You might have to get them seperately (can't help you with that). I further suggest that you check out the ubuntu forum for posts regarding nvidia. You might find some usefull advise there as well. Good luck |
