graphics cards and chips

Juanito:
From the attached:
--- Code: ---(--) RADEON(0): Chipset: "ATI Radeon Mobility M7 LW (AGP)" (ChipID = 0x4c57)
(II) RADEON(0): Output LVDS using initial mode 1024x768
(II) RADEON(0): Front buffer size: 3072K
(II) RADEON(0): VRAM usage limit set to 25804K

--- End code ---
..it looks like the radeon driver is being used.

..but:
--- Code: ---(EE) AIGLX error: dlopen of /usr/local/lib/X11/modules/dri/radeon_dri.so failed (/usr/local/lib/X11/modules/dri/radeon_dri.so: cannot open shared object file: No such file or directory
(EE) AIGLX: reverting to software rendering
(II) AIGLX: Screen 0 is not DRI capable
--- End code ---
I guess this is because Xorg-7.6-3d is not loaded - what does the following give:
--- Code: ---$ ldd /usr/local/lib/X11/modules/dri/radeon_dri.so | grep found
--- End code ---

I forget the exact format required in xorg.conf to change the resolution from 1024x768 to 800x600, but you should find an example in these forums or the xorg man pages.

Juanito:
Something like this perhaps:
--- Code: ---Section "Screen"
Identifier "Screen0"
Device     "Card0"
Monitor    "LVDS"
SubSection "Display"
Depth     24
Modes     "800x600"
EndSubSection
EndSection
--- End code ---
..but googling on xorg.conf and "ATI Radeon Mobility M7 LW (AGP)" is probably better

cast-fish:
yes Juanto

thanks for your continued interest...

i will try the 3D version maybe...

i wonder why it's limiting VRAM to 25 megs when the card
has 64 megs

Also you notes of screen rez...is exactly what i already tried
but doing a text boot the way you described and pulling down
the drivers and starting the gui up means i can't find an Xorg conf
file....the one i did find in etc x11 would not let me EDIT it......permissions denied

when i dropped down back to the text prompt became a super user
and ran "Xorg -configure" it gave outputs and an error at the saying
screen amounts do not match the amount of screens available etc

this above activity generated a file calld Xorg.conf.new which again
could not be edited...

Vince.

Juanito:
you need root privileges to edit /etc/X11/xorg.conf

You can start whatever text editor you're using as root by using the running man icon, entering your text editor name and checking the "run with sudo" box.

Alternately you can use "sudo vi /etc/X11/xorg.conf" from a terminal window.
