Acer Al1916W monitor problem


I recently installed Ubuntu 8.10 and everything is great besides one thing. I get this annoying "Input not supported" message before i log in. After i log in my screen flickers black then it goes away. From what i have read searching google i need to change my xorg.conf file to accept the 1440:900 resulation but thats were my problem is.

Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Files"
EndSection

Section "Module"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:2:0:0"
Option "UseEDIDFreqs" "FALSE"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
EndSection

Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

The xorg.conf file doesnt seem to recognize the monitor at all and doesnt list any resolutions. My video card is ATI Sapphire X1650 and i installed the drivers from ATIs website.

for grins why don't we check what the system sees when it probes your monitor ?

xresprobe fglrx

ddcprobe

get-edid

The first two tools are part of the xresprobe package, and get-edid is part of the read-edid package. You will probably have to install the packages to use the tools.

These all fail on my current system because my KVM Switch blocks the probe



Then what you might want to try is calculating a modeline for your monitor to force a specific resolution and refresh rate using the cvt command.
Code:
it-lenny:~# cvt  1440 900 refresh 70
# 1440x900 69.81 Hz (CVT) hsync: 65.62 kHz; pclk: 126.00 MHz
Modeline "1440x900_70.00"  126.00  1440 1528 1680 1920  900 903 909 940 -hsync +vsync


Code:
Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Files"
EndSection

Section "Module"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
# 1440x900 69.81 Hz (CVT) hsync: 65.62 kHz; pclk: 126.00 MHz
Modeline "1440x900_70.00"  126.00  1440 1528 1680 1920  900 903 909 940 -hsync +vsync
EndSection

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:2:0:0"
Option "UseEDIDFreqs" "FALSE"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
EndSection

Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1440x900_70.00"
EndSubSection
EndSection
then restart X to apply the settings change CTRL+ALT+BACKSPACE

(I'm assuming you are making a backup of the xorg.conf file before making changes too... just in case)

Should i continue with your instructions on changing the xorg.conf?

Ok i edited the xorg.conf like you said and the floating "Input not supported" went away but now the picture is thrown off. Like it is projecting the picture as if it was not a widescreen, there is a huge black area to the left.

Err yeah I goofed and calculated 1400x900 @ 60 instead of 1440x900 @ 70 which the query said your monitor should support..

I updated my previous post to correct my mistake so give those corrections a try.

Sorry about that.. Guess I was more interested in getting to Lunch than paying attention to what I was doing.

Sorry bout all my flipflopping around to get the changes updated.

Glad it's working for you now

and I can see that ddcprobe provided the most useful output.. I'll file that info away for next time....
