Acer Intel GMA 4500M poor graphic performance

Hey all

I’m running Opensuse 11.4 64bit with KDE on a Acer Aspire 5732z notebook. I have a few problems with the graphics.

Hardware: Intel GMA 4500M graphics.


  1. When I boot the Suse boot splash screen shows and then the monitor goes black. I plug in the external monitor and the notebook monitor stays black but the display is fine on the external. Then I run a script which sets the screen brightness on the notebook. Then the monitor is fine. How can I fix or automate this?

Here is the script (can’t remember where I downloaded it)


current=$(sudo setpci -s 00:02.0 F4.B)

if  "$1" == "up" ]]

if (( current < 5 ))
elif (( current > 255 ))

sudo setpci -s 00:02.0 F4.B=$(printf "%02X" $current)

  1. With the intel driver the performance was bad. When I ran glxgears I get about 20 fps. Changed to the intellegacy driver. The performance is better but still not good. Glxgears gives 35 fps. How can I improve this? Maybe the graphics card isn’t installed/configured correctly. How can I check this?

  2. While playing videos in SMplayer the frame rate isn’t constant (jitters kinda thing). Think this problem will be sorted if the graphics is sorted.

I have a usb modem. Have set up the usb_modeswitch and that works. Want to know how to set it up that if I plug in the modem the usb_modeswitch is executed. Think it should be in a udev rule or something?

Thanks for any advice. I’m still a newbie so please be gentle :).
