Subject: Getting a 800x480 screen under X
Hi all!
OK I know we've done this topic before but I can't seem to find anything that
addresses this problem ...
I'm trying to get Red Hat 6.2 working on my L100 ... I'm having one hellava time
trying to get X to recognise the 800x480 screen.
The following lines exist in my XF86Config file (with a pile of stuff in and around
them):
==============================
HorizSync 30 - 64
VertRefresh 50 - 100
...
#Modeline "800x480" 40 800 864 928 1088 480 481 484 509 +hsync
#Ya I tried the one above too with no joy
Modeline "800x480" 36 800 824 896 1024 480 491 493 525
Modeline "640x400" 25.175 640 664 760 800 400 409 411 450
Modeline "640x480" 25.175 640 664 760 800 480 491 493 525
ModeLine "800x600" 36 800 824 896 1024 600 601 603 625
Modeline "1024x768" 44.9 1024 1048 1208 1264 768 776 784 817 Interlace
...
Section "Device"
Identifier "Neomagic Corporation|NM2160 [MagicGraph 128XD]"
VendorName "Unknown"
BoardName "Unknown"
# Option "overrideValidateMode" "true"
#Somehow X resents the line above ... it sounded promising as a fix :-(
EndSection
...
Section "Screen"
Driver "svga"
# Use Device "Generic VGA" for Standard VGA 320x200x256
#Device "Generic VGA"
Device "Neomagic Corporation|NM2160 [MagicGraph 128XD]"
Monitor "My Monitor"
Subsection "Display"
Depth 16
Modes "800x480"
ViewPort 0 0
EndSubsection
EndSection
==============================
Unfortunately, I keep erroring out with a 'No valid modes found.' error. In the
traceback, I can see it say:
SVGA: NM2160: Removing mode (800x480) that won't display properly on LCD
SVGA: NM2160: Removing mode (640x480) that won't display properly on LCD
... and so on
which is a little absurd ... anyone got any ideas on how to resolve this problem? I
can get it *working* at 640x480 but for some silly reason, it decides to stretch to
fit horizontally which gives really weird pixels plus I can't scroll to see whats in
the bottom 1/3 of the desktop!
I'm not sure exactly which version of X I'm running but its whatever comes standard
with Red Hat 6.2 ...
