iBook G3 desktop repeating i.e. incorrect monitor detection

Postby dasmian » Mon Jul 19, 2010 9:52 am

Hi

I installed Mint on to my iBook (12" G3) from your instructions in the early hours of today. Thanks. I don't know how i managed it, as i'm a complete novice as far as Linus is concerned and in the use of terminal, run / command lines !

Anyway, it seems to have installed fine, apart from the fact that the screen (1024x768) is only being 70% used i.e. at resolution of 800x600 - the rest is black on the right hand side and below the desktop is duplicated. Mint seems to have wrongly detected the monitor as being only 800x600.

Do you have any advice?

Help would be most appreciated.

Thanks

Damian

Ps Ummm, just found another problem but i will see if i can get the screen sorted first :-)

If you started up, you issue a CTRL-Alt-F1, you will get into a tty. Login with your username and password. Then do the following:

Code: Select all
wget http://mac.linux.be/files/xorg/ibook1.txt
sudo mv ibook1.txt /etc/X11/xorg.conf

Then you either reboot or you do CTRL-Alt-Backspace

Hi

Thanks for your help.

I followed your instructions (i hope) but on restart i got an error:

----------------------------------------------------------------------------------

Failed to start the X server (your graphical interface). It is likely that
it is not set up correctly. Would you like to view the X server output
to diagnose the problem? ...

(==) using config file:"/etc/x11/xorg.conf"
Parse error on line 23 of Section Screen in file /etc/X11/xorg.com"

(EE) Problem parsing the config file
(EE) Error parsing the config file

Fatal server error:
no screens found
----------------------------------------------------------------------------------

Any ideas?

Cheers

That gave an error as well :-(

So, i decided to have a look at the original 'ibook1.txt' file online and noticed what looked like a 'typo' on it at line 23, see:

--------------------------------------------------------------
Section "Module"
Load "bitmap"
Load "dbe"
Load "ddc"
Load "dri"
Load "glx"
EndSection

Section "Monitor"
Identifier "LCD"
HorizSync 60-60
VertRefresh 43-117
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "LCD"
Device "Video"
DefaultDepth 24
SubSection "Display
Depth 24
Modes "1024
Ã
—768"

EndSubSection
EndSection

Section "DRI"
Mode 0666
EndSection

Section "Device"
Identifier "Video"
Driver "r128"
BusID "PCI:0:16:0"
Option "PanelWidth" "1024"
Option "PanelHeight" "768"
Option "UseFBDev" "true"
Option "NoInt10" "true"
EndSection
-------------------------------------------------------------

I then downloaded it, and changed the 'typo error?' to:

Modes "1024x768"

and then uploaded it to some web space, and then followed your instructions as before, and believe it or not, it worked!
:-)

Cheers, thanks very much for your help.

Thanks for pointing that out. I will have a look at my own page, if there is a mistake. I took it from here.
It should now work. I changed it, there was indeed a typo in that file. Great.
