Description Joe Harrington 1999-11-13 01:39:48 UTC

I have a Toshiba Tecra 8000, 13" screen, with NeoMagic.  When I asked to
configure X and selected 1024x768, it was unable to find any modes at all
and the server failed to start.  I reinstalled without configuring modes
and got the 640x480 mode that the install uses.  The XF86Config file
distributed with the XFCom server worked fine under RH 5.2 at 1024x768...

I just brought over the old file and it works under 6.1.  It defines just three
modes, all of which are defined in the file I was left with after the install.
However, for some reason they work only when other modes are not also defined.
Here is the working Monitors section:

Section "Monitor"
    Identifier  "Generic Multisync"
    VendorName  "Unknown"
    ModelName   "Unknown"
    HorizSync   30-64
    VertRefresh 50-100
# 640x480 @ 60 Hz, 31.5 kHz hsync
    Modeline "640x480"     25.175 640  664  760  800
                                  480  491  493  525
# 800x600 @ 60 Hz, 37.8 kHz hsync
    Modeline "800x600"     40     800  840  968 1056
                                  600  601  605  628 +hsync +vsync
# 1024x768 @ 60 Hz, 48.4 kHz hsync
    Modeline "1024x768"    65    1024 1032 1176 1344
                                  768  771  777  806 -hsync -vsync
EndSection

I also eliminated the 1152x864 modes from the Modes lines in the Screen section,
since there aren't that many pixels on the laptop's display.  And obviously, I
changed the Monitor name to "Generic Multisync".  Those were the only changes.
Here's a diff:

Comment 2 Trond Eivind Glomsrxd 2000-07-11 17:00:30 UTC

Is this still a problem with 6.2?

Comment 3 Trond Eivind Glomsrxd 2000-07-25 17:37:12 UTC

No feedback, so I'll assume it works with 6.2 (which works fine with my own
Neomagic)

Comment 4 Joe Harrington 2000-07-25 20:08:09 UTC

Sorry not to get back.  My laptop is still in 6.1 and has to stay there until
the class I'm teaching with it is done (2 weeks and counting).  If I find the
problem again I'll reopen, otherwise no news is good news.
