Hello,

i have an ati 7000 card which works fine with the vesa driver. Now i want to switch to the radeon driver (which supports dri), but changing the "driver "vesa"" line in XF86config-4 to "driver "radeon"" and restarting the x-server results in an huge virtual desktop. I don't know why this happens. Can someone Help me please?

my XF86config-4 :

Section "Files"
FontPath "unix/:-1"
EndSection

Section "ServerFlags"
#DontZap # disable <Crtl><Alt><BS> (server abort)
AllowMouseOpenFail # allows the server to start up even if the mouse doesn't work
#DontZoom # disable <Crtl><Alt><KP_+>/<KP_-> (resolution switching)
EndSection

Section "Module"
Load "dbe" # Double buffer extension

SubSection "extmod"

>> restarting the x-server results in an huge virtual desktop.

What do you mean by huge? do you mean a high resolution or a low one. Do you mean things are cut off the screen?

does pressing "ctl & alt & +"or "ctl & alt & -" do anything?

Hi,

>What do you mean by huge? do you mean a high resolution or a low one. Do you mean things are cut off the >screen?
I mean that the resolution is very low and only a part of the desktop is shown on the screen (i can scroll to other parts of the desktop by moving the mouse in this direction)

>does pressing "ctl & alt & +"or "ctl & alt & -" do anything?
No, everything stays the same.

Thanks,

try and replace that with ...

Subsection "Display"
Depth 24
Modes "640x480"
#Virtual 1280 1024
ViewPort 0 0
EndSubsection

if you login succesfully try the next resolution.

I have found that at some resolutions my desktop does the same as yours.

( else try changing the colour depth to 16, you will need to also change

DefaultColorDepth 24

to
DefaultColorDepth 16


let me know what happens

edit: I think it is more likely to work at a higher resolution

@kinasz
I tried all possible resolutions at 16 and 24 bits per pixel and none except "640x480" worked.

Any other suggestions ?

Thank you,
karl

You will need to adjust the visible resolution setting in the config file.

Good Luck

Try this...

Subsection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
ViewPort 0 0
Virtual 1024 768

Hello kinasz,

>Virtual 1024 768
You're right, this has been the error.

Thank you very much for your great help.
karl

Glad you got it going
