ati radeon 9600 scrambled

Asked by Dave Luttinen

Newbie alert.

I gladly am dumping M$ for Linux. Linux is superbly crafted.

Computer: Fujitsu N5010 laptop, Graphics: ATI Radeon 9600. The driver installed is proprietary. (NOTE: I would prefer an open source driver if anyone has a suggestion)

This problem appeared on both my initial Ubuntu 7.10 installation and upgraded Ubuntu 8.04.

(1) When I recover from hibernation, my screen is scrambled.

(2) When I ctrl+alt+F2 out of gnome, the text is fine. When I ctrl+alt+F7 to return to gnome, the screen scrambled -- it looks like a vertical scramble because parallel lines an undefined distance apart are displaying in parallel, but it is unreadable. Then, with ctrl+alt+F2, no display at all.

(3) Cold starts display fine.

xorg.conf contains these tidbits:

Section "Device"
 Identifier "ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]"
 Driver "fglrx"
 Busid "PCI:1:0:0"
EndSection

Section "Monitor"
 Identifier "Generic Monitor"
 Option "DPMS"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Device "ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]"
 Monitor "Generic Monitor"
 Defaultdepth 24
 SubSection "Display"
  Modes "1400x1050"
 EndSubSection
EndSection

Many thanks.

your graphics card is actually supported by the open source driver (full 3d included), you can see here for more info: https://help.ubuntu.com/community/RadeonDriver - switching to the open source driver may fix things for you.

Following the instructions on the ../RadeonDriver document fixed my problems. Many thanks.
The display is faster and cleaner with the "aiglx" open source driver than it was with the "fglrx". Rendering of fonts has improved.

Hello.
I've got a similar problem except when I add the fglrx drivers to my xorg.conf, x won't start, just gets a blank screen. The previous link does the same thing to the display.
It works fine without any driver specified in the xorg.conf but I cant enable any desktop effectes due to that Direct Draw is not enabled (I think?).
Anyone experiencing the same problem as me?
