Hello All,
I recently upgraded Ubuntu to 9.04, had it all working ok before upgrading, now having refresh rate problems.

Have ATI Radeon HD3850 AGP card, downloaded and installed drivers from AMD, new for April, not sure what version, installed all ok etc.

I had previously edited the xorg.conf file (before upgrading) to get a higher refresh rate, ie 75hz instead of 60 and worked ok, since upgrading I havn't been able to do this as easily.

I have tried ading the horizontal sync and vert refresh 'bits' and various mode lines with @ sign and an underscore as fould in help posts elsewhere, still didn't work.

Now have blinding headache looking at screen at 60hz!

I am a noob to Ubuntu, but not beyond a bit of editing of files etc.

Here is my xorg.conf file:

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

Section "Files"
EndSection

Section "Module"
EndSection

Section "ServerFlags"
Option "Xinerama" "off"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
HorizSync 30.0 - 80.0
VertRefresh 50.0 - 120.0
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"
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
I have tried putting in the 'mode' lines under display ie: (Mode 1280x1024@75 or 1280x1024_75), this didn't work either way, I was able to get the higher refresh before upgrading and yes my monitor is capable of 75 hz, and the vert refresh and horz sync figures are right, just at a bit of a loss now.
Cannot select 75 hz in ati catalyst control ot the display option under 'system', any help much appreciated, off to find ibufren, thanks.

The modeline thing needs to go into 2 places in the xorg.

Like so:

(With your own settings of course).

Does anybody know how to fix this problem or should I be talking to ATI/AMD about this?

Have been working on this for 4 days now and getting very frustrated.

This is a simple matter of a refresh rate on a monitor!!!!!!

Does anybody know what has been changed between versions to prevent a simple line edit in xorg.conf being accepted??????

Anybody with some technical knowledge please give us a hand, not feeling very happy with Ubuntu anymore arrrrrrrrrrrgrgrgrgrggrrg

Those two kinda need to be exactly the same. The bottom one is a reference to the top one.

I think that sometimes the ati driver doesn't use the xorg.conf settings and I think this is meant to force it:
aticonfig --initial --input=/etc/X11/xorg.conf
Not too sure about this step though...so do some research first & make a backup of xorg.conf first.

The problem is in the drivers. The AGP 8350 was never officially supported by AMD/ATI as they had not intended for that GPU family to be made into AGP cards. The various manufacturers that make ATI cards were the ones that decided to make an AGP version anyway, and in doing so, it requires special "hotfix" drivers to work correctly in Windows. AMD does put out these drivers, but they are unofficial, unsupported and only available for Windows so far. :(

As far as I know, no one has written anything that gets these cards to work correctly in Linux or BSD. Sucks because my main system used to be Ubuntu until I got that card.

Yeah - I'm not surprised. They read about as far as "Linux driver" in your request and posted an automatic response. To be honest, I was surprised they even made the unofficial hotfix drivers for XP. Oh well.
