Re: [LUG] TFT Monitor problem

Er... I typed in the xorgconfig bit and changed some bits, got out of it and tried startx, screen blanked and it went back to the command line and gave a load of technical stuff I didn't understand. When I reset the computer it just booted into the command line and asked me to log on. Is there any way of re-installing SuSE to try again? I'm sorry if this is getting tiresome but I know practically nothing about Linux so it could take a while to fix this.

AFAIK Suse 10.0 uses X.org 6.8.2 not XF86.

Now that would make sense - it would explain why Suse didn't select the right settings for this monitor originally.

In which case, xf86config is the WRONG program to call, sorry. Adam, you need to call the xorg version: xorgconfig (intuitively enough).

That said I believe the config file isn't that much different. Others here will jump all over me if I'm
wrong
about the latter.

The config file does change from XF86 to X.org but it appeared to be more of an upgrade rather than a rewrite when I had to transition from xf86 to xorg.

man xorgconfig says:
Note that the default name used by xorgconfig for the xorg.conf file is system-dependent. For instance, on some systems, xorg.conf-4 is used, and on OS/2, XConfig is used.

I'm using:
/etc/X11/xorg.conf
(but haven't deleted my old /etc/X11/XF86Config yet)

One test you could do:

$ ls -l /etc/X11/X
That's a symlink to either /usr/bin/X11/Xorg or /usr/bin/X11/XFree86

It's a good while since I used a SuSE distro but I always found their "sax2"
a useful tool when setting up the monitor. Hopefully they still use it.

First login to XP and check which display settings it uses and note down
anything you think important especially the H-sync and V-sync frequencies.
Also look at the monitor specs if you have the handbook for it.

Then shutdown/reboot and fire up SuSE.
At the command line login as root and then type
       sax2
and press the return/enter key.
If sax2 starts up then somewhere in the dialogs you should be able to set
the H-sync and V-sync frequencies. Use the ones you obtained from the XP.
Or try H-sync at 81Khz and V-sync at 75Hz (I believe these are the
frequencies for a "standard" TFT.)

You should be able to test your setup from sax2 and if it doesn't work press
the appropriate key (ESC ?) to get back to the dialog and try again with
different settings. NB I'm not sure about TFT monitors but I know you can
destroy a CTR monitor if you get things like picture breakup, strange noises
etc. In that event QUICKLY use the appropriate key to abort the test.
If you find a setting that works OK use the option to SAVE and QUIT.

The safest thing to do at this stage is reboot unless you definitely know how to
start X. So at the command line type
      shutdown -r now
The machine will shut the system down properly and then reboot
(that's what -r means).

Hopefully you should now be able to get to the login GUI when you fire
up SuSE.

If there ain't no sax2 then Google around to see what tool SuSE are
using for monitor setup and test. Rest assured SuSE is a popular distro
and you should be able to find lots of info about it. And don't forget the
SuSE manual (there used to be a readable copy on the SuSE website)
also the SuSE forums on their website.

Hope this is of some help.

Keith
