Problems with ATI Catalyst drivers

[Digitalone]

Hi everyone. I'm an Italian user who uses Kubuntu 10.04 on Toshiba L500 1v5 with ATI Radeon HD 4650 graphic card (sorry if my English is bad ).

I've installed ATI Catalyst drivers replacing open source driver because I need hardware acceleration for reproduction of HD videos with VLC 1.1.x.
Unfortunately, the reproduction isn't good with all videos that I tried. When a video is reproducing, before some parts of the image freeze and after they return normal. This often occurs...
Can someone help me?

This is my xorg.conf configuration:

  Section "ServerLayout"
    Identifier   "aticonfig Layout"
    Screen   0 "aticonfig-Screen[0]-0" 0 0
  EndSection

  Section "Module"
  EndSection

  Section "Monitor"
    Identifier  "aticonfig-Monitor[0]-0"
    Option    "VendorName" "ATI Proprietary Driver"
    Option    "ModelName" "Generic Autodetecting Monitor"
    Option    "DPMS" "true"
  EndSection

  Section "Device"
    Identifier "aticonfig-Device[0]-0"
    Driver   "fglrx"
    Option    "OpenGLOverlay" "on"
    Option    "UseFastTLS" "1"
    BusID    "PCI:1:0:0"
  EndSection

  Section "Screen"
    Identifier "aticonfig-Screen[0]-0"
    Device   "aticonfig-Device[0]-0"
    Monitor  "aticonfig-Monitor[0]-0"
    DefaultDepth   24
    SubSection "Display"
     Viewport  0 0
     Depth   24
    EndSubSection
  EndSection

Re: Problems with ATI Catalyst drivers

have you tried to change any of the vlc settings? i've noticed it can be quite pickey when using a video backend. opengl is almost always gonna be bad w/ the ati driver if you have desktop effects turned on. i have a hd4830 and have had my share of issues w/ the proeritary driver over the past 2 years or so i have had it for.

Yes. I've tried to set other video output like X11, XV, framebuffer, etc., but nothing is changed...

I've tried to set XRender, but it seems that the graphic card doesn't support it. From bash, giving "sudo aticonfig --overlay-type=Xv" it returns:

Error: invalid string value for --ovt option. 
Please check aticonfig help info for supported overlay type.
aticonfig: parsing the command-line failed.

From Preferences->Desktop->Advanced->Composition, setting "XRender", instead of "OpenGL", effects don't run.
However, I also reproduced videos with effects turned off, but it's the same result.

i have a hd4830 and have had my share of issues w/ the proeritary driver over the past 2 years or so i have had it for.

Today ATI's released new 10.8 version. I've installed it but it's the same result again...
Here's new xorg.conf:

Section "Module"
EndSection

Section "Device"
	Identifier "aticonfig-Device[0]-0"
	Driver   "fglrx"
	BusID    "PCI:1:0:0"
EndSection

Section "Monitor"
	Identifier  "aticonfig-Monitor[0]-0"
	Option	  "VendorName" "ATI Proprietary Driver"
	Option	  "ModelName" "Generic Autodetecting Monitor"
	Option	  "DPMS" "true"
EndSection

Section "Screen"
	Identifier "aticonfig-Screen[0]-0"
	Device   "aticonfig-Device[0]-0"
	Monitor  "aticonfig-Monitor[0]-0"
	DefaultDepth   24
	SubSection "Display"
		Viewport  0 0
		Depth   24
	EndSubSection
EndSection

Section "ServerLayout"
	Identifier   "aticonfig Layout"
	Screen   0 "aticonfig-Screen[0]-0" 0 0
EndSection

Hope someone can help me...
