Regarding your font size: I noticed a similar issue going from PC LCD to big TV LCD. With KDE you can increase it. In KDE 4.2, open System Settings -> Appearance -> Fonts and then change Force fonts DPI: to 96 DPI. If you still need bigger try the next one (125 I think). I never figured how to do this in xfce. Maybe in one of the .hidden files.

I don't remember how this is done in kde3 but it would b similar. K(start) button - settings..etc.

Not sure about your tearing issue. My guess is you'll have better performance with the catalyst driver. I'm using an HD3200 with fglrx and even with compiz on the system works well, until I play a dvd and then have blinking problems until turn compiz off.

Radeonhd works OK for me in 2D, you may also have to use newer libdrm and mesa but I'm not sure for your hardware. I would imagine a HD3600 would be faster than a HD3200 so your system should be fast enough.

what does the following output

cat /var/log/X*log | grep EE
cat /var/log/X*log | grep WW

What do you mean by "gl output"? If that refers to the OpenGL output of mplayer etc. then this will probably not work properly. The correct output is xv.
Also does the tearing disappear if you disable the internal panel or switch to 1920x1080Scaled mode with xrandr during playback?

When I used the gl output i meant the OpenGl output. The correct output may be xv but when I used the catalyst driver I experencied tearing and flickering everytime the xv output was used (on the laptop screen and on the tv). The OpenGl output was the only one i could use without crying.
I will try to disable the panel with xrandr.

Regarding the fontsize problem forum1793 was right. Forcing the font to 96 dpi did the trick. BTW kubuntu 9.04 is shipped with KDE 4.2.

My aim is to be able to watch videos without any tearing or flickering effect on my laptop screen and on my tv (but not necessarily at the same time). I don't care if the driver i have to use lacks 3D as I don't play. From the few tests I did, the 2D acceleration of the radeonhd may be better than the fglrx one.

**OrangeOne** · 21 June 2009, 04:28 AM

Unfortunately disabling the panel (xrandr --output PANEL --off) had no effect on the tearing.

**suokko** · 21 June 2009, 08:29 AM

You should disable composite window manager and try again without it. Kwin does Xrender composite so it an be enabled without 3D support. Composite wm happens to be most like reason to tearing with randeon/radeonhd. (btw, Does radeon work instead of radeonhd?)

Also try to run

Code:

sudo dpkg-reconfigure -phigh xserver-xorg

That will clean your xorg.conf from fglrx stuff (you should back up it in case you want to install fglrx back)

If you're running fglrx then using gl output works best. If you are running radeon or radeonhd on a 6xx/7xx then Xv should work fine without tearing, and since the 3D driver is still in development you can't use GL output anyways.

**OrangeOne** · 21 June 2009, 12:11 PM

Before switching to the radeonhd driver I uninstalled the fglrx driver (using the provided uninstall script). Then I executed the command "sudo dpkg-reconfigure -phigh xserver-xorg".

As far as I know I'm not using Windows composite nor any kde effect (they are
disabled).

I haven't tried radeon instead of radeonhd as there is no use: I want hdmi output. Furthermore I only get tearing when playing a video using the hdmi output (on my tv). So far everything is perfect on my laptop screen.

**bridgman** · 21 June 2009, 12:20 PM

Just in case it helps, the difference between radeon and radeonhd w.r.t. hdmi is the ability to output audio over hdmi - both of them output video over hdmi.

I'm starting to think your tearing problem might be as simple as the tear-free code syncing video to your laptop screen's timing rather than to your external screen. I think the logic is a bit different in radeon, but all I remember for sure is agd5f specifically talking about how the multi-screen case was handled for tear-free in radeon vs not hearing a similar discussion for radeonhd. The code could be identical, I don't know, but it wouldn't hurt to see if radeon handles tearing on the second screen any better. If it does, then that's an easy clue for radeonhd...
