RH 7.3 + iiyama monitor = no X, why?


I still cannot identify clearly the problem, so any suggestion is welcome.
Newly installed RH 7.3, iiyama CRT monitor HM903DT, + Leadtek GF4200. During installation anaconda had a real difficulty to detect my monitor, finilly resolving to generic. Upon customizing I choose the closest model of iiyama and... now I have no grafi interface, X does not start, the screen is blinking and I see in text mode "login", blinking.
What should I blame: me, RH, iiyama or Leadtek?
FYI: it works under W2k but no way to see the POST screen, it takes about 5-8 sec to find an appropriate frequency, HF - 0, VF can be 500-1000 (according to selftest of iiyama).
Thx,
BF

Make sure that in /etc/X11/XF86Config-4 that the HorizSync and VertRefresh are set as follows. I don't know where you got "HF - 0, VF can be 500-1000", but I'm supprosed you didn't blow your monitor.

HorizSync 30-130
VertRefresh 50-200

IME, it's not a wrong monitor selection. It's a wrong video selection. Especially true for certain distros.

Let me guess. You have a GF2MX or better card? If so, at next install, try X 4.1.0 WITHOUT 3D acceleration, and then you WILL be presented a test button. If it checks out...

Actually I have Leadtek 250LE MyVIVO (64Mo).
>try X 4.1.0 WITHOUT 3D acceleration,
I ran trough the install process and actually "tested" my config, it passed through... until reboot. How can I try "X 4.1.0 WITHOUT 3D acceleration"? When I select Video adapter or...
Tnx,
BF

"at next install" makes sense?

There's a button on the right-most. It's Advanced/custom.

Nothing, I reinstalled RH with Generic monitor, and now I don't know what to do next, since if I modify etc/X11/XF86Config-4 in a wrong way, I'll have to reinstall it all again... How can I try some other monitor without getting to the same result? I tried A902MT-v (it's EXACTLY the same model as my HM903DT) - no way :-(
Tnx,
BF

Do you know exact spects for your monitor - Vertical refresh and Horizontal Sync? If you do, during OS install you can specify these values when installation gets to the X configuration part.

1280 1024 at 85Hz is recommended, 1600 1200 at 85Hz is possible max, but I tested it at 1024 786 at 60Hz (default) and it did not actually work upon reboot.
Tnx

Just run setup from the commandline and mess around.

When the gui tools mess up, I'm a big fan of using /usr/X11/bin/xf86config, the command line utility. I just checked the ranges for your monitor, took a minute to find a site in english, Here it is.

Here's the ranges to give X:

Horizontal Frequency: 30-130KHz
Vertical Frequency: 50-160Hz

Cheers,

Finegan
