April 21st, 2009, 08:51 AM
hi, i use Sharp Aquos LCD TV for monitor, i use ordinary vga cabel, and have like this:

- pc turn on, motherboard manufacture pic show up fine, tv said 800x600 60Hz
- entering boot loader, still ok, tv said 720x400 70Hz
- entering ubuntu progress bar, still ok, tv said 640x480 60Hz
- then suddenly blank, first tv said 720x400 70Hz, then -- (no data), then there's note at center screen said "Not compatible with this signal"

so, why not compatible?
and how to solve it?
i assume it resolution or refresh rate problem, i wonder if there's script which i can write so ubuntu will jump to spesific resolution and refresh rate at booting so it can enter the system.

I found the problem, it work well with openSUSE 11.1, it on monitor chose, I don't know why ubuntu can't detect, my monitor detected as VESA in openSUSE.

now, how can i enter the GUI, anyone know how to change monitor from command line (I only can enter ubuntu from recovery command line)?

using xubuntu 9.04 now, and needs some tricks to make graphic works.

1. installing xubuntu on safemode
2. change xorg.conf

Section "Device"
Identifier "Configured Video Device"
Driver "intel"

Section "Monitor"
Identifier "Configured Monitor"

# 1360x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 84.72 MHz
Modeline "1360x768_60.00" 84.72 1360 1424 1568 1776 768 769 772 795 -HSync +Vsync


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

DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1360x768_60.00"


done, but it really takes whole day to configure xorg.conf

I answer my own question :cry:, well, see the good side, now i know more about xorg.conf O:)
