Monitor parameter change locks up system


Help

I installed the SUSIE 10.0 DVD (downloaded from the web site 18 Feb 2006), applied all updates using YAST,

The problem I have is simple. When I logged into the user account, the entire screen image was shifted to the right by 3 cm. (1 inch), and there was a constant annoying discomfort causing flicker on the screen. Resolution was 1024 by 768, on a recognized 19 inch Samsung monitor.

I wanted to reduce the sweep times to something that would be more reasonable to stop the flicker, so I dropped the horiz freq from 30 - 85 to 30 - 70, hoping it would centre the image and stop the flicker. I adjusted the value, and it saved it. Then I lost the image, the monitor turned itself off, and the keyboard locked up (no key worked, as demonstrated by the leds).

Without the changes, I tried to run Frozen-Bubble (a child game for my daughter, and the system immediately froze, as the monitor locked up).

Right now, I can boot, but when I log in, the system is lost. Both keyboard and monitor lock up. I cannot even get into reboot.

In the emergency restart mode, I can log in as root. But what do I do after that.

What, short of a re-install, can I do to recover?

It seems that you need to configure again the X Window System (the GUI that Linux uses). In order to do that you need to know the hardware specifications of your Monitor (horiz and vert freq), the resolutions supported and the maximum dimensions of the display. You also need the specs of your graphic card. In case you have an Nvidia or ATI graphic card you need to install the proprietary drivers. Also I don't think is a good idea changing the horiz frequency, this could damage your monitor!.

Once you have all this info, login as root and type:

sax2

this is the program of SuSE to configure the X server. Follow the instructions and pick the appropiate for your system.

Xwindows system problem

I already know I have to reconfigure the system, I was asking users who may have done it, to indicate to me, how to do it or with which module to start.

In the worst case, I can reinstall from DVD. If I do that, I will not lose anything except some download time taken up by YAST.

Thanks for the reply

You don't need to reinstall. If you can access the console and login as root, it means that the installation went properly except the X Server.

So when you boot with the failsafe mode, log in as root and then type
Quote:
sax2
and follow the instructions.

I suspect that your problem is related with the driver that is used for your graphic card. In case you can't find a specific driver use vesa. This driver will work until you find the right one for your graphic card.

To follow up. sax2 fails. I get the ascii propeller and then the monitor turns off, as does the keyboard. Both die.

There is nothing wrong with the bios, and since the system is a 2 hard disk system, where the 2ndry one is core4, I can boot from core4 without any problem.

I want to evaluate SUSIE, and so far, my evaluation is mixed. Should I wait a few months for it to have a proper keyboard and gui support?

I would still like to try one more thing before I go the reinstall route. Please recommend an action.

Victorh, I am sure you have a non-english keyboard on the system. What did you have to do, if anything, to get it recognized?

Well Leslie sometimes sax2 refuse to cooperate, this is too sad. I think it has some bugs, hope they fix it for SuSE 10.1.

One thing you can try is edit manually the configuration file for Xorg, you can do this with any file editor, I use vim, but the following can be applied to other editors:

1. Log in as root.
2. Edit the file xorg.conf. Type:
Quote:
vim /etc/X11/xorg.conf
3. To change the layout of your keyboard, Find the following section
Quote:
Section "Input Device"
Identifier "Keyboard1"
Driver "kbd"
Option "XkbRules" "xfree86"
Option "Xkbmodel" "pc105"
Option "Xkblayout" "es"
End Section
Then type "i" so you enter in insert mode in vim.
In the line of Xkblayout change the appropriate one for you. In my case "es" is for an Spanish Keyboard.
The other options may vary for you, you can also change them
4. If you want to verify the specs of your monitor go to the following section:
Quote:
Section "Monitor"
Identifier "Monitor0"
DisplaySize 352 2164
HorizSync 30-96
VertRefresh 50-160
Option "DPMS"
....
End Section
Note. Put the rigth values for your Monitor.
5. If you want to try to change the graphic driver. go to the following section
Quote:
Section "Device"
Identifier "ATI Graphcis Adapter"
Driver "fglrx"
.....
Note. Put the adequate driver. As I mentioned before you can put "vesa" to verify if this is the problem. You can change it later

Once you've done the modifications, type ":wq" to save the file.
If you're not sure about doing some modifications, you can make a backup of this file before editing it.

As you'll se you have plenty of options to configure the X Window System through the file xorg.conf.

Hope this helps.

Muchos Gracias.

Jo comprendo mucho espagnole. My language is english, but I deal a lot in French.

I am familiar with VI, and have access to an AIX system. Our ERP software runs on AIX with Informix database.

I will try the edit of the xorg.conf file. I did it earlier today to reset it to what I thought was default values.

One more try with your help.

I had to use the vesa driver, and I took the extra wide parameters for width that was in your config file. The system has come up in the proper mode, and with the proper resolution.

I am now trying the keyboard. I somehow think that the Canada French Multilingual is not the right one. The menus say it is, but the output is the France azewrty.

I most certainly appreciate your help. Without the clues you provided, I would be onto my other choice (Core5, due out Monday).

Leslie, de nada...

I'm glad that you have your GUI up and running. Although you have some details so you can cover all the bases.

If you want a better perfomance of the X System you need to put the adequate driver for your graphic card. Now that you have a GUI you can use Google to find the rigth one. Use the following command (as root) to check your graphic card:

Quote:
# lspci
As for your keyboard, I'm afraid that I don't have the knowledge of what keyboard map you need. I guess that, as everything in Linux you'll need to try some. Hopefully somebody will give you a clearer answer.

I'm sure you'll find SuSE very enjoyable, just try it and find if it suits your needs.

I'm aware of the imminent release of Fecora Core 5, I'll also install it as soon as I can download it!. It's another of my favorites distros. Also we are waiting the release of SuSE 10.1 in the next month. This is one the features that I like most of Linux, it's always evolving. That's nice...
