I had quite a time after upgrading to 2010.10 to get the display to show circles instead of slightly flat ovals. I have an Acer X233w monitor and the video card is reported as follows:
id:
display
description: VGA compatible controller
product: Radeon RV200 QW [Radeon 7500]
vendor: ATI Technologies Inc
physical id:
0
bus info:
pci@0000:01:00.0
version: 00
width: 32 bits
clock: 66MHz
capabilities: agp agp-2.0 pm vga_controller bus_master cap_list
configuration:
latency = 32
mingnt = 8
resources:
memory : e8000000-efffffff(prefetchable)
ioport : a800(size=256)
memory : ff8f0000-ff8fffff
memory : ff8c0000-ff8dffff(prefetchable)
I could not find or get the proper driver to work via the PClinuxOS Control Center(frankly I believe this is broken and needs work, I have other issues with it too.)
A Google search finally lead me to a page that described my problem in regard to a laptop using the same video chips. The solution was to edit the /etc/x11/xorg.conf file and replace Section "Device" with the following:(warning, save a backup of the original file first)
Section "Device"
Identifier "device1"
Driver "ati"
Option "DPMS"
Option "AccelMethod" "exa" #(can help with composite - comment out if want to use xaa)
Option "AccelDFS" "true"
Option "BusType" "AGP" #(use only if internalAGP based card)
Option "AGPMode" "4" #(can use 8 if card is capable check out result of dmesg |grep agp)
Option "EnableDepthMoves" "on"
Option "FBTexPercent" "80"
Option "BackingStore" "true"
Option "EXAOptimizeMigration" "true"
Option "MigrationHeuristic" "greedy"
Option "DRI" "on"
Option "ScalerWidth" "2048" #Remove/comment out this if screen has pink / discoloured arears)
Option "RenderAccel" "on"
Option "ColorTiling" "on"
Option "EnablePageFlip" "on"
Option "DynamicClocks" "off"
Option "ExaNoComposite" "false"
EndSection
This seems to work for me with the exception of some weird icon behavior in the system tray with programs I've placed there using the program alltray. These worked fine on my previous install of PClinuxOS2009 with KDE4 installed. If anyone has a suggestion about this please post.
Anyway, hope this of help to some.
