RH 7.3 + iiyama monitor = no X, why?

Big Finger · 08-09-2002, 03:04 AM

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.

ok, make use of log files, what does /var/log/XFree86.0.log complain about?

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.

I had the same problem a couple of weeks ago. I hadent connected a mouse to my computer and X wouldnt start. When i connected the mouse and rebooted it finally started!

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,
