    I have this issue, the problem of course stems from having compiz fusion disabled on 8.5 and 8.6... currently 8.4 does not exhibit this issue.

      screensaver freeze with ati linux driver 8.6

      Hello!

      After install of the new ati linux driver 8.6 the opengl screensaver have a freeze after 10 min. I dont know how to fix that. I have tried to change the screensaver, but it does not work. Any idea? I use Ubuntu 8.04 and compiz fusion version 0.76, all packages are up to date.

      The problem with screen flickers in opengl applications is solved with the new driver 8.6, but now there is the freeze of the screensaver, wich is opengl.

      With the ati linux driver 8.5 and 8.4 the was not the problem with the freeze.

        I have tried to deactivate compiz fusion, but then there is the same problem with the freeze. I think, it is not a problem of compiz fusion, but i hope, that it is solved with driver 8.7 ...

          Thanks Bridgman, I appreciate your help. Let me know if you need me to capture any logs or anything of the sort.

            Interesting. I ran into another issue last night when I tried to launch a very simple 2D windows utility using Wine. The whole display went nuts, visual corruption everywhere, with the screen doubled horizontally (everything at half width and duplicated on the left and right sides of the screen). Totally unreadable due to the mosaic blocking everywhere.

            I used CTRL-ALT-BACKSPACE to restart X and everything was fine. Started the same wine app with no problem on the second attempt. I'm running the latest Wine from their direct repo.

            This screen corruption issue was different from the one I described earlier in the thread... that one was a momentary scramble in the screen buffer while System Monitor was drawing to the screen. This one was an ongoing scrambled output from the card that seemed more like a hardware-level issue.

            Any thoughts? Anyone else experiencing this sort of thing?


            [edit] The visual corruption I experienced looked very similar to the third image in the Cedega thrad: http://phoronix.com/forums/showthread.php?t=10940

            This is on Hardy 8.01, Catalyst 8.6, Mobility X1400, latest Wine (1.1.0 stable from WineHQ Ubuntu repo).

              Hi,

              Performance has got slower with each release glxgears was around 18000
              now down to 15000-16000. Also nexius slows down some times, I mean it's hardly cutting edge. I can play crysis fine in windows 1600x1200 with a few shadows on medium the rest high, but on linux it struggles with nexius

                i managed to fix this corruption, while still maintaining the ability to play videos using the Xvideo extension, please look at my device section to fix your own desktop...
                Code:
                Section "Device"
                	Identifier  "aticonfig-Device[0]"
                	Driver      "fglrx"
                	# enable XVideo out.
                	Option	    "VideoOverlay" "on"
                	Option	    "OpenGLOverlay" "off"
                	# Textured 2D was on.
                	# Turned off due to bugs with rendering the gnome system monitor.
                	Option	    "Textured2D" "off"
                	# Textured X renderer has default of on.
                	# Turned off due to bugs with rendering the gnome system monitor.
                	Option	    "TexturedXrender" "off"
                EndSection
                and on a quick note, on 8.6 this does not fix the issues with wine, however most everything else works fine... i tested it on a Radeon X1900GT.

                  Why would Textured2D and TexturedXRender default to "on"? The developers who participate here are pretty adamant that those features are still experimental and are disabled by default.

                  Could be an "oops" in the 8.6 release?

                    that's a good question... however as i stated before the system monitor exhibits the bugs only when one disables compiz fusion... and by setting those settings i mentioned before to off it fixes it, in my experience, while not breaking the XVideo support.

                      What card are you using?

                      TexturedVideo is necessary for Xv acceleration on the R5xx and higher.

                      It should be set by default though... I assume you're using an older chipset, due to your use of VideoOverlay? You shouldn't need to specify it in xorg.conf though, if that's the case. The driver is set up to properly use VideoOverlay or TexturedVideo as appropriate depending on the chipset.

                      I'm just trying to eliminate possible secondary variables.

                        ok... as to help reduce the secondary variables, here is the most important details...


                        Ubuntu 8.04 ( with all the latest patches )
                        FGLRX 8.6 ( currently in use, most problems fixed by the above mentioned bug, except for the issues related to Wine.)
                        FGLRX 8.5 ( not using, but was unusable for 1600x1200 resolution. )
                        FGLRX 8.4 ( end regressions here, only bugs related to dual monitors really. )
                        AMD Athlon 64X2 3800+ ( manchester core )
                        Epox EP9NAJ+ Ultra
                        1024mb Corsair valueselect memory (DDR400, PC 3200)
                        CMedia based Auzentech sound card.
                        Radeon X1900GT (R580 core )
