Hi, Read on to see how to make it work :). Today I did an upgrade from SuSE 7.3 (XFree86 4.1) to SuSE 8.0 (XFree86 4.2). To my surprise, X didn't work anymore (w/the same config file). sax2 does detect the card but doesn't start. When I try to run the server using my old config file (working fine in 4.1.0) it says (relevant section): ---------------- IBM ITUX97E Color, Single, TFT (EE) R128(0): No valid modes found (EE) Screen(s) found, but none have a usable configuration. Fatal server error: no screens found --------------- After some fussing around the web it turns out some other people were asking the same question (also on this list) but no good answer has come up. I have a Dell Latitude C800 laptop, ATI Mobility M4, 1600x1200 TFT display. I know that the HorizSync should be 31.5-90 and VertRefresh should be 60 (this is what they are set to in my XF86Config that's working). Out of sheer desperation, I changed the VertRefresh from 60 to 55-65 to see what happens. Bingo ! It works (!?!?!?!). I've attached the XF86Config-4. I assume this is because of some sort of "approximation" that takes place when the actual VertRefresh is calculated ? (59-61 doesn't work, BTW; although xvidtune says the actual frequency is 59.26). The mode is described in /var/log/XFree86.log as: (**) R128(0): Default mode "1600x1200": 160.0 MHz, 81.2 kHz, 65.0 Hz (II) R128(0): Modeline "1600x1200" 160.00 1600 1664 1688 2160 1200 1200 1203 1250 +hsync +vsync What happened between 4.1.0 and 4.2.0 to require this change (60 -> 65) ? I think this is pretty bad - I guess all TFTs have a fixed VertRefresh and they will be affected by this problem. I assume this is only happening with ATI cards ? Hope this helps, Cornel.
