Suggestions for an [Radeon] ATI graphics card as alternative to onboard HD3200


Hi all

I get lots of horizontal lines flashing across the screen (is it 'screen tearing' that i hear about) when anything other than a static display; particularly when watching videos, but also when shutting down tabs on browser! - or projectM etc.

I have not tried the proprietary driver, would rather not unless it is seriously recommended to improve matters. I have adjusted many settings using xrandr and one or two other things] but nothing has improved.

Therefore I have concluded that the on-board HD3200 is not good for 1080p at 60Hz (best the monitor does). Or is it the monitor now I have said that grrrr!! ooerr

Any way, please will any one suggest/recommend a decent - but not expensive over the top gaming stuff - card that will be able to play 1080p over hdmi without 'artifacts'? (its an old asustek M4A78 phenom II x4 board)



Given I am no expert on these linux graphics matters (or hardware), any other advice or things to try would also be welcomed.

Thank you .
Good evening.

Well, try creating the file /etc/X11/xorg.conf.d/10-radeon.conf and place the following in it:
Code:
Section "Device"
        Identifier  "Radeon"
        Driver      "radeon"
        Option      "DRI" "3"
        Option      "EXAVSync" "no"
        Option      "SwapbuffersWait" "false"
EndSection
Restart your X server and see if it helps.

You may want to drop into runlevel 3 and use "startx" for this test. There's a chance that your X server won't come at all and it is easier to ctrl-c the server and fix any changes that way.

I've got a Radeon HD 6310 on this machine (an HP-635 at the moment) and it is able to drive 1080p.

Hello Richard, thank you ever so much...that is a massive improvement. There are still the odd line as described, but not nearly as 'bad' as it was.

I did have a 20-radeon.conf from reading the bits I could find to try, but all I had was the DRI3 entry.

I will have a read of the other settings - trouble is a lot of them I do not really understand.


Thank you again. Do you think a dedicated card would improve things ? Is there anything else I could try in the radeon.conf....in the meantime I will go search the net again now I have some more clues from you.

You can try adding
Code:
Option "TearFree" "on"
in the same file to see if that helps.

Code:
man radeon
will tell you all the possible options. If you don't understand an option, you can always try it to see if it helps.

EDIT: To answer your other question, newer cards provide much better performance than older ones. I think a relatively cheap external video card could provide much better performance than the HD 3200 (which dates from 2009 or so).

Many thanks again - it is much improved....not without the odd one the two, but its so much better and its acceptable too (for me).
I will have a read of the radeon options, but i think its pretty good now.

I'll mark it as solved.
Best wishes.
