ProLiant ML115 stuck in 640x480 Fedora 7 (64 bit)

Hi
I have FC7 x86_64 installed on my ML115. My problem is that despite using a Dell monitor (E153FPc) which is capable of 1024x768 I can only get 640x480 resolution.

This is what I get from lspci -v:

05:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G200e ServerEngines (SEP1) (rev 02) (prog-if 00 )
Subsystem: Hewlett-Packard Company Unknown device 31fa
Flags: bus master, fast devsel, latency 0, IRQ 18
Memory at fb000000 (32-bit, prefetchable)
Memory at fdefc000 (32-bit, non-prefetchable)
Memory at fd000000 (32-bit, non-prefetchable)
Expansion ROM at fdee0000
Capabilities: Power Management version 2
Capabilities: Express Legacy Endpoint IRQ 0
Capabilities: Message Signalled Interrupts: Mask- 64bit- Queue=0/0 Enable-

and my xorg,conf file looks like this:

# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "gb"
EndSection

Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1024x768"
HorizSync 31.5 - 48.5
VertRefresh 40.0 - 70.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "mga"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768"
EndSubSection
EndSection

This is a problem as at this resolution many of the buttons on GUIs are not visible making it very difficult to configure the server.

Anyone else set up Fedora on a ML115? Any suggestions gratefully received.

I believe the ML115 only has 2MB video RAM, so I don't think it can do 1024x768 at 24-bit color. Try changing the color to 16-bit depth or going to 800x600 if you need higher depth and see if that helps.

thanks for the reply. I found by chance that reducing the colour depth sorted the problem. At least I now know why this should be.

Hello
I am experiencing the same 640x480 issue when trying to install Fedora 6 on the HP DL140 G3 ...... Have you resolved your issue???

Thanks in Advance

Hi Frank

Yes I sorted this out. The problem was related to trying to use too high colour depth. Make sure you reduced your colour depth to 16, this should allow 1024 x 768 resolution.

OK Thanks
I guess I will have to install Fedora in text mode first
then change the xorg.conf
