Help: Strange X behaviour ( Video Card Clock )

Help: Strange X behaviour ( Video Card Clock )

Post by Chierico Dant » Sat, 19 Sep 1998 04:00:00

Hi everybody, I'm new to Linux, I installed RedHat 5.0, but my Video
Card ( Matrox G100 )
is not supported yet.

I'm using XFree86 in VGA mode, but when I call startx, it checks the
Video Card frequencies
and everytime they're different !!! Why?
And since they're different sometimes I can run the XFree86 only at
640x480 while
other times I can go up to 800x600.
If I manually configure the file and write the frequencies that the day
before worked perfectly,
it still doesn't work, the 800x600 mode is blank.

My machine is a Pentium II 300, and the Video Card is a Matrox G100.
I don't know what monitor I have, I can't find any brand name on it!!

Thanks in advance for the help anyone will give me :-)

1. Need Help with strange sound-card behaviour


Ensoniq sound-scape PnP, PnP bios (which is why I can get it to work),
Red Hat 4.0, 2.0.18, etc.  The sound card is working; I can cat to
/dev/audio, and I can run xplaycd and play cd's.


1) I noticed that the volume when playing a CD under Linux was much
   lower (even on max volume under xplaycd) than when playing under
   Win95 (yes ... it took the red hat disk a few days to get here,
   I had to use SOMETHING in the mean time ... it's actually pretty

2) if I cat a .au file to /dev/audio WHILE a CD is playing, suddenly
   the volume jumps up by a large amount, comparable to what Win95

3) no matter how far "down" I turn the sliders in xplaycd, the sound
   never disappears.

Any ideas?  Is this my sound config, or is this xplaycd's fault?


ps below cat /dev/sndstat
