ATI Redeon HD 4550 very jerky display

djmills · October 23, 2009, 9:05am

Hi I just changed my graphics card. The computer came with an nVidia GT220 which has no Linux driver.

I installed the proprietory ATI driver and get the full screen resolution - so static images look great - but anything moving (scrolling screens, movies, moving windows on the display, etc.) is very jerky. One click up on the scroll bar of a text based web page took 7 seconds to jerk its way up.

Then I tried the drivers at http://www2.ati.com/suse/11.1. The result was slightly better but only just.

The computer is a Dell Studio XPS i7 Core, with 8GB RAM running oprnSUSE 11.1.

Movies are unwatchable unless I make the window very small - less than 800x600.

If I boot Vista moving images are fast and clear.

Any help or suggestions would be appreciated.

Here’s my /etc/X11/XF86Config file:

These are the same symptoms I’m getting with 11.2 RC1 and using the default
driver. The card is ATI Radeon HD 2400. I also had the same trouble with
nVidia GeForce FX 5200 in 11.2 M8 but it’s OK in RC1.

I’m getting none of the problems in 11.1 with the default driver.

Try removing all the Options from the “Device” section in your xorg.conf file. They are not required for the fglrx driver. In fact I think the VideoOverlay option is the culprit, it should be off.

Te be sure the new settings are used, best is to remove the file amdpcsdb from /etc/ati, on the commandline enter ‘aticonfig --initial’ and restart your computer. (You need to have root permissions to remove the file and to execute the command. If hou don know how, open a terminal, enter ‘su’ and provide the root password.)

Good luck

djmills · October 24, 2009, 2:19am

Hi Admo, thanks for the advice.

I removed those Options from Device, removed the amdpcsdb file (there was also an amdpcsdb.default file which I didn’t touch) and ran aticonfig --initial. Then I rebooted.

aticonfig --initial changed the xorg.conf file but didn’t re-instate the Options in Device.

Unfortunately things haven’t improved at all. Watching a movie is still a jerky mess.

Any other ideas?

The new xorg.conf file is:

I’m happy to supply my /var/log/Xorg.0.log file if that would help (it wouldn’t let me add it to this post as it made it too long).

Thanks, David.

ATI released a new driver - ati-driver-installer-9-10-x86.x86_64.run. I uninstalled all previous versions - both Yast2 installed ones and the one from the previous ati download.

But still things are no better.

tcubed_bus · October 25, 2009, 7:17am

Hmmm, you’ve already tried some of my ATI suggestions, but here are the others:

Your xorg.conf file has a lot of extra stuff in it. In my system, I removed most of the font paths; also the modules and mode entries–no need with EDID these days. Check your /var/log/Xorg.0.log file for errors and warnings.
I assume you did not run sax2. ATI recommends aticonfig and amdcccle.
The compiz user forum has a longrunning thread regarding setting up ATI cards. Worth a look; google user djdoo.
See your /usr/share/ati/fglrx-install.log file for install info.

What does htop say when your system gets unresponsive?

djmills · October 25, 2009, 11:36am

Hi HTH, Thank you VERY VERY MUCH!

During my multiple attempts to install both the openSUSE’s versions of the ATI drivers and ATI’s themselves I never got any messages suggesting that the install hadn’t worked. Indeed I went from only having a screen resolution of 1280x1024 to the full 1920x1080.

This led me to believe that the install had worked.

But your suggestion of looking into /usr/share/ati/fglrx-install.log led me to find the culprit. It had a message that it couldn’t find /usr/src/linux/include/linux/version.h and some other stuff. So I installed kernel-source and reinstalled the ATI 9.10 driver. This time /usr/share/ati/fglrx-install.log had a lot of stuff that it didn’t before including instructions to

cd /lib/modules/fglrx
./make_install.sh

Then I rebooted and now web page scrolling is lightning fast, watching movies is clear and smooth, etc. Basically all works as expected.

So thanks to all for their help.

djmills · October 25, 2009, 12:54pm

OK, next issue. No desktop effects are working. OpenGL seems to be missing. How do I enable OpenGL with the ATI driver?

admoel · October 25, 2009, 2:57pm

Hi djmills,

Good you git things working so far. Why do you think OpenGL is the problem? OpenGL should not be the problem, because the necessary librairies are installed with the ATI-driver.

Did you enable desktop effects? If not, you first should enable it. It is not clear to me if you are using KDE or Gnome. In KDE in the menu go to ‘Personal Settings’, click Desktop, and in Desktop effects check “Enable desktop effects”. In Gnome in the menu select ‘Control Centre’, in the ‘Look and Feel’ group select Desktop Effects and enable the Desktop effects. By the way, Alt+Shift+F12 makes it possible to toggle desktop effects on and off. Maybe you can try if desktop effects is suspended by pressing this key-combination.

If desktop effects still is not working, check the /var/log/Xorg.0.log file for errors. This provides more information where the problem is. If you see errors, send the log file.

Admo

djmills · October 27, 2009, 1:34pm

Hi, I did enable Desktop effects. I’m using KDE 4.1.3.

I get the message "Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values.

Check your X configuration. You may also consider changing advanced options, especially changing the compositing type." I have tried all combinations of the possible settings and none work.

One page I found on the web on another forum suggested that OpenGL might be the culprit in this circumstance.

Or have you got any other ideas?

Thanks,

David.

tcubed_bus · October 27, 2009, 3:37pm

Hi-
Probably not the culprit, but in your xorg.conf file, you have the value of composite as “1”. Usual practice is to have this value “enable”. The man page for xorg.conf is silent as to the extension section in general, and does not mention “enable” as a boolean equivalent to “1”.

Might be worth a shot.

HTH

djmills · October 28, 2009, 3:54am

I just checked that and this time (since the successful reinstall) it was set to “on”. I changed to “enable”. I’ll reboot soon and see.

djmills · October 29, 2009, 6:15am

No - it didn’t make a difference.

It always complains that it failed to activate desktop effects.

Here’s my more recent xorg.conf (the one from the new install of ATI driver that solved the jerky screen issue).

Hi-
xorg.conf has always had a confusing and redundant data entry philosophy. Monitor, device, screen… Why do I need all that stuff? It’s one of the reasons that ATI has moved away from using xorg.conf as its persistent data store, and toward its own database. That said, I can make a few comments.

Did you run

aticonfig --initial

? When I did, I got identifiers within xorg.conf prefixed with “aticonfig-”.

You have way too much stuff in your xorg.conf file. Take out the module section. Most of the font paths are useless. And with EDID, you can remove all those mode entries.

An excerpt from my xorg.conf:

Section "Monitor"

        Identifier   "aticonfig-Monitor[0]-0"
        Option      "DPMS" "true"
EndSection

Section "Device"
        Identifier  "aticonfig-Device[0]-0"
        Driver      "fglrx"
        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

Sorry for the VERY delayed response. At the time I discovered that if I reinstall the proprietary ATI driver after every kernel update then all works well. It is a bit of a pain that you have to re-install every time. I never had to do this with all my previous computers that all had nVidia graphics cards. I’ll make sure all my future computers have nVidia cards too.

I’d put back the GT220 nVidia card that I have except that it is very noisy - the fan is very loud.

Actually, if one is using the proprietary nVidia driver, one also often has to re-install the proprietary nVidia driver after every kernel update. I have 3 PCs with different nVidia card graphics, and this is true for all 3 : GeForce FX5200, GeForce GTX260, GeForce 8400GS.
