Hello people,

I have a problem with my graphics card RADEON 9200 SE.

I have recently installed lenny so my version is 2.6.26-2-686

and the graphics is not as good as before. Namely I can not get the maximal resolution
of which my monitor is capable, and which I had under etch. This is 2048*1536@85

now the display ois only 1600*1200@85 and the gnome "preferences" menu
refuses to do better.
I have the "xserver-xorg-video-radeon"
installed and also "xserver-xorg-video-radeon-dbg"

The Xorg.0.log contains some lines like this:

(II) RADEON (0): Supported Future video modes
(II) RADEON (0): #6 hsize: 2048 vsize 1536 refresh 85 vid 23009

however it remains stil... err... Future video modes,
or better to say for me
the PAST video modes, since I had them with etch.

Is it possible to get them again with Lenny?

Thanks for the help

Stefan

What is the output of 'xrandr'?

Well the driver is definitely not reading 2048x1536 as a supported resolution, or the VirtualSize it's defaulting to is less than 2048x1536. Can you attach your /etc/X11/xorg.conf file.

Adam

I am sorry I tried and got the reply that the text is too long

i will post the first one third of it.

I understand that the xserver does not recognize the max resolution as possible, and this is exactly my problem...

Oh I am sorry

you wanted xorg.conf,

I thought you wanted Xlogs.

here is the xorg:

(I changed only one line in the automatically generated xorg.conf, I added
"radeon", but the result is the same...

Try this:

If that doesn't work, I would suggest trying a newer version of the driver.

Adam

Adam,

Thanks! it works like magic.

all the intermediate resolutions are also available.

What does it mean "Virtual"?
I tried already something like

DefaultDepth 24
Subsection "Display"
Depth 1
Modes "1680x1050"
EndSubSection

but it never worked.

What is the difference?


Thankd again!

Stefan

The "Virtual" keyword is used to describe a screen size (horizontal x vertical resolution) which is NOT the real resolution of the monitor.
For example, if I have a monitor that only displays 1024x768, I could specify a VIRTUAL desktop size of 1600x1200, and the desktop image would actually be 1600x1200, which is larger than that which can be displayed on the monitor, requiring scrolling up/down/left/right to access the outer edges of the image.

Sasha,

thanks for th explanation.

Does that mean that I can set ANY resolution
with this "Virtual" mode?

for example 5000*3000?

the limit resolution of my monitor as specified in the
notice is 2048*1536@85

You could set whatever virtual size you want, to a point. The maximum is not unlimited but rather, it is limited by both the X server, and your video hardware. Off the top of my head, the limit per screen *might* be somewhere around 4800-something on the horizontal, and 3800-something on the vertical.

You'd have to check your cards documentation, driver docs, and X server man pages, to find out what the limit would be for your setup. I can't accurately remember what the max is.

Sasha

Sasha, thanks

Although there is something which I do not understand here.

I thought that my monitor was not capable to display the images
which have more than 2048*1536 pixels
(of course it can, but at the cost of poorer quality,
so that a group of 4 points on the original image
will be displayed as 1 single point of the color ahich is the average
of the 4 colors in the original).

Now you say that it is capable to display the images of size
4000*3000

So will it really display 4000*3000 different points on the screen?

How can it do this?

It may well happen that I do not understand something basic here,
since all this seems quite strange to me.

I think you are "trying" to understand, but are missing my point.

The monitor will NOT show an image which is larger than it is capable of showing. That's all there is to that.

Imagine it like this:

I have a 1024x768 monitor, but I set a virtual image size of 1600x1200. The way this works, is the same way as if I had a 1600x1200 monitor, except that it has a "frame" or "window" in front of it that is 1024x768. So the "window" is smaller than the monitor showing the image. I must move the window around in front of the monitor, in order to actually see the edges of the image on the monitor.

Understand?

Are you using the vesa driver instead of the radeon or the fglrx one?
Vesa's abilities are very very limited, eg no xv, no 3d, only 4:3 resolutions etc...

Sasha:

yes I think I understand, thanks for the explanation.

The point is that the monitor is capable of 2048*1536@85
- real resolution, not virtual.

I would like to obtain this, the reason is that it gives better quality of images.
I had this resolution before, and it is strange to me that I can not
obtain it now with lenny, which seems to be better version of debian than etch.

jim_p: i am using the radeon driver, not the vesa, neither fglrx

many thanks for your help!
