    I get the first OpenGL program hanging too, but for some reason my X server is not affected. It could be because something on my system is unsetting LD_LIBRARY_PATH on X startup. And I need LD_LIBRARY_PATH set so that the ati get used (due to the soname bug).

    Also - I think Textured2D has a side-effect of disabling accelerated offscreen pixmaps, which I need otherwise I get the corruption around the mouse cursor bug.

      I got this at my /var/xorg.0.log:

      [glesx] __glESXExtensionInit: No GL ES2.0 capable screen found!

      What does it mean??

      PS: I loaded module glesx at "Modules" Section with the only option that works here option "TexturedXrender" "True" cause otherwise it didn't load the glesx module.

      When I use option "Textured2D" "True", I cannot connect to X BUT xorg.0.log writes the following:

      (II) fglrx(0): GLESX enableFlags = 14
      (**) fglrx(0): Option "XaaNoOffscreenPixmaps" "True"
      (II) fglrx(0): Using XFree86 Acceleration Architecture (XAA)
      Screen to screen bit blits
      Solid filled rectangles
      Solid Horizontal and Vertical Lines
      Driver provided ScreenToScreenBitBlt replacement
      Driver provided FillSolidRects replacement
      (II) fglrx(0): GLESX is enabled
      (II) fglrx(0): X context handle = 0x1
      (II) fglrx(0): [DRI] installation complete
      (II) fglrx(0): Direct rendering enabled
      (==) fglrx(0): Silken mouse enabled
      (==) fglrx(0): Using hardware cursor

      Any Ideas??

        I didn't put glesx in the "Modules" section, it gets automatically loaded by the fglrx driver, after other fglrx extensions (ATIFGLRXDRI and FGLRXEXTENSION) have been set up.

        I wouldn't worry too much about getting these undocumented options working - we will only discover that they are undocumented for a reason.

          I have to agree with you my friend...

          Maybe the Textured2D option is working for certain radeon families...


          • #15
            How did you discover these hidden options?


            • #16
              I just ran strings on - there's a list of text items that include the documented options such as VideoOverlay, but the list also includes things which aren't valid options.

                Where is this file located?

                  alright.. I spent the last two evenings sifting through disassambler output from aticonfig, trying to figure out --pplib-cmd options. I didn't make much progress cause the stupid thing just wouldn't accept any commands, untill I came across the EnablePPLIB config option two hours ago! :P

                  setting EnablePPLIB seems to mess up the aticonfig --lsp ouput.

                  My assambler knowledge is limited so some things could be wrong and as ejs1920 said before, there maybe a reason this stuff is hidden... so don't complain if you melt your card or something..

                  num == some number

                  get version
                  get clock
                  get swcntl
                  get pstate
                  get pmapping AC
                  get pmapping DC
                  get pmapping DCLOW # DCLOW doesn't work here
                  get psbatterylevel AC|DC|DCLOW
                  get eventCount Thermal
                  get eventCount VPURecovery
                  get temperature num # doesn't work
                  get FanInfo num # if I enter a number I get zero values back
                  get FanSpeed num # doesn't work)
                  get UserState 3d|2d
                  get activity # doesn't work
                  get ODParam # doesn't work
                  get ODLevel num # probably requires number
                  get ODDefaultLevel # doesn't work
                  get fs PowerPlay
                  get fs OverDrive
                  get fs ReducedRefreshRate
                  get fs ClockGating
                  get fs ReducedColorDepth
                  get fs OverDriveTest
                  get fs PowerBudgetWaiver
                  get fs PowerExpress

                  set fs PowerPlay enabled|disabled
                  same as get fs ...

                  set pmapping AC|DC|DCLOW optimalBattery|highBattery|balanced|highPerformanc e|optimalPerformance
                  set psbatterylevel AC|DC|DCLOW num (num == some number or two. doesn't work here)

                  set FanSpeed num num # probably expects two numbers, doesn't work
                  set UserState 2d|3d num num # doesn't work
                  set ODLevel num,num,num # doesn't work

                  notify psrc dc|ac|dclow
                  notify batterylevel num
                  notify suspend
                  notify resume
                  notify restState|forcedState|exclusiveMode begin|end
                  notify DispConfigChange
                  notify screenSaver|VPURecovery|Thermal|textMode|3dhigh|3d low|inactive|InitCompleted begin|end
                  notify AppSafeTo|AppUnsafeTo AdapterSwitch|ModeSwitch
                  notify AdapterDisableSafe

                  reset fan num

                  enum thermal num

                  an example command line would be:
                  aticonfig --pplib-cmd "get version"

                  which returns:
                  PPLIB version is 1.3 and is inactive!

                  which might explain why most things don't work. my card is a radeon 9550, maybe that's another reason ..

                    I tried both the options but I don't notice any improvements while using compiz (always slow scrolling) or while using other apps.

                    (Radeon 9600)
