Laptop with dual monitor

gilan · 11-05-2006, 05:08 AM

Hi all,

I've a laptop ACER Aspire 2000 and a Fedora Core 4 running on it. Everything worked good until I decided to have a dual monitor, so I put my old CRT monitor (phillips 107S) near by my laptop and i started configuring it.
After many tries with xorg.conf, I installed ATI software from official page (i think) and I could get both monitor running. BUT, the shape of my mouse pointer changes when I move from one screen to the other, i mean, the mouse pointer in my laptop screen is the normal (arrow) but when i move to the CRT monitor, the mouse pointer shape changes to a quite big white square...

I already check xorg.conf and everything looks fine. I havent found anything similar in google, so I'm lost! I don't know where to find! Any help will be appreciated!

Thanks in advance!

Hey, this is a bit of a stab in the dark, but maybe it is something to do with hardware/software rendering of the cursor. Look for a line like this

Code:

Option "SWcursor" "true"

in your xorg.conf. If it is there then try it with the other value(true/false), and if it isn't there, try it with both values.

Good luck

I've tried both values and in different places, I mean in <<Section "ServerLayout">> and in <<Section "InputDevice">> and same results as before. I'm gonna post my xorg.conf, I hope this gives light to the problem:

Code:

Section "ServerLayout"
        Identifier     "Multihead layout"
        Screen      0  "aticonfig-Screen[0]" 0 0

I've got the exact same problem. I'm using Ubuntu 6.10, Radeon X600. Has anyone figured out how to fix this?

By adding the following SWcursor setting to the xorg.conf file, the cursor rendering problem is solved.

[HTML]
Section "Monitor"
Identifier "Generic Monitor"
HorizSync 28.0 - 50.0
VertRefresh 43.0 - 75.0
Option "DPMS"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[0]"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
Option "SWcursor" "true"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[1]"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection
[/HTML]

A new problem arises, the mouse leaves a trail of white squares when using the scroll wheel inside a "scrollable window". This effect takes place on both screens. When I move the cursor to the other screen, all the white squares are gone.

the following guide solved my problem:

I just needed to install the latest drivers...

Hello everyone,
I still have problems with fglrx drivers.
I followed step-by-step the guide suggested by Dogmatica; i did the tests the guide suggested and now I know that I didn't succeed in installing the proprietary driver.
In the log file I find:

(WW) fglrx(1): ***********************************
(WW) fglrx(1): * DRI initialization disabled! *
(WW) fglrx(1): * 2D acceleraton available (MMIO) *
(WW) fglrx(1): * no 3D acceleration available *
(WW) fglrx(1): ***********************************

and a few lines later:

(EE) AIGLX: Screen 1 is not DRI capable

I did all the troubleshooting in the guide but nothing changes.
I post also this:

glxinfo | grep vendor
Xlib: extension "XFree86-DRI" missing on display ":0.0".
server glx vendor string: SGI
client glx vendor string: ATI
OpenGL vendor string: Mesa project: www.mesa3d.org

glxinfo | grep "direct rendering"
Xlib: extension "XFree86-DRI" missing on display ":0.0".
direct rendering: No

My computer is a Asus w3450n, with a Mobility Radeon 9600 M10.
I don't know what to do now!!!

:S

heeeeeelp!!
