Dear All,
I have a laptop, there're ATI Mobility Radeon X1300 display card and wide
screen with 1280x800 resolutions on it.
I'd like to use the native ati driver, Unfortunately I can't find any
available driver about this card on the internet. So that I must choose
another way to use this card.
I configured the vesa driver in /etc/X11/xorg.conf, and then start the X. I
got the following message in /var/log/Xorg.0.log:
...
(II) VESA(0): First detailed timing is preferred mode
(II) VESA(0): redX: 0.575 redY: 0.359 greenX: 0.319 greenY: 0.532

(II) VESA(0): Searching for matching VESA mode(s):
(==) VESA(0): Write-combining range (0x0,0x1000) was already clear
...
After reading the manual, I add the "ModeLine" line in the
/etc/X11/xorg.conf to use the additional video mode:
...
Section "Monitor"
Identifier "My Monitor"
HorizSync 31.5 - 64.3
VertRefresh 50-70
ModeLine "1280x800" 68.9 1280 1301 1333 1408 800 804 808 816
End Section
...
and change "Monitor" section as following:
...
Section "Screen"
Identifier "Screen 1"
Device "* Generic VESA compatible"
Monitor "My Monitor"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1280x800"
ViewPort 0 0
EndSubsection
EndSection
...
OK, restart the X.
The X was started, but the resolution is still 1024x768.
I checked /var/log/Xorg.0.log carefully, and then I found the following
message in the log file:
...
(II) VESA(0): Total Memory: 256 64KB banks (16384kB)

ranges.

(**) VESA(0): Built-in mode "1024x768"
(**) VESA(0): Built-in mode "800x600"
...
It said "1280x800" mode cound not to be found, but I have added this mode
into /etc/X11/xorg.conf. Why it can not to be detected?
If I can use the additional video mode, I can use my wide screen under
1280x800 resolution I think. Could anybody give me some hints about how to
apply the additional video mode?
Thanks.
Janvier Pang.
