Dear Sir or Madam: Sorry to trouble you. I have installed the redhat and suse in my desktop, but there is a display problem about my Monitor: I can only enter into the X by 640x480 with 16 depth. If I config it into 1024x768(with 16 depth) in XF86config and then type "startx", the error message appear saying that there are no mode about it. However, I can use 1024x768 with 24 depth in windows XP. Is there anyone who can tell me the reason? My video card is Intel 845 and the monitor is Dell E151FPb which is a Flat Panel monitor. The resoluation of it is in below: Horizontal scan range 30 kHz to 61 kHz (automatic) Vertical scan range 56 Hz to 76 Hz (automatic) Optimal preset resolution 1024 x 768 at 60 Hz Highest preset resolution 1024 x 768 at 75 Hz And you can also find its Specifications in http://docs.us.dell.com/docs/monitors/E151FPB/English/specs.htm My XF86config file is in below, please help me check it.
