  • I'm getting some real nastiness here. The following happens when fglrxinfo, glxgears, glxinfo finish:

    Code:

      glxgears

      32286 frames in 5.0 seconds = 6457.051 FPS

      31869 frames in 5.0 seconds = 6373.660 FPS

      So far Compiz 0.10.3 runs well and fast enough for me. I have not noticed any slow scrolling or display issues with Firefox.

      /var/log/Xorg.0.log has no errors but does have excessive AIGLX warnings for example:
      (WW) AIGLX: 3D driver claims to not support visual 0x23

      These warnings are consecutive from 0x23 through 0x72

      • I'm successfully using the new ATI 8.42 driver on 7.10 ubuntu (x86 build because linksys is too lazy to provide a 64 bit driver for the wusb54gsc) and it works with a bit of jimmying.

        I'm on an x800 XT PE and I get 7000fps in glxgears which is more than I get in the open source ati driver (~5000) but I'm having the same simple 2d-choppy issues that others are having. Interestingly compiz does not freeze anymore when I set the refresh rate for v-sync, so the 3d effects look great and tear free (and quite fluid) but the 2d stuff is SO CHOPPY.

        None the less I would have random lockups before (all USB devices would lose power, screen would lock, system would not respond on SSH/to ping/etc) so I'm going to see if this helps.

        • Blank 3D windows with my X1950 PRO AGP

          I've installed 8.42.3 both on Ubuntu Feisty and PCLinuxOS with same results:

          whenever I execute 'glxgears', 'fgl_glxgears', running 3d game or screensaver I get a blank window or a black display.

          'cat /var/log/Xorg.0.log | grep "EE"' gives me this error:

          (EE) fglrx(0): Failed to enable interrupts.

          'fglrxinfo' is ok:

          OpenGL renderer string: Radeon X1950 Series
          OpenGL version string: 2.0.6958 Release

          IMO 8.42.3 suck, ATI sucked, sucks and will continue to suck. that will gonna be my last ATI video card ever, my next one will be Nvidia. ATI still does'nt pay attention to older than HD series products. they promised 8.42 will solve older AGP cards problems which it didn't as I anticipated.

          -Waiting whole 3 months was a huge waste of time for me, I've done being ATI's sucker anymore.

          • Resume & 8.42 problem

            Have a FireGL v5200. Did the Chipid option/driver hack to try 8.42, and the /etc/ati/control from 8.40.4 to get rid of the logo. When I suspend, happily, it suspends now (before SLUB got in the way, running Gutsy 32-bit, btw). On resume, I always have it hang trying to chvt to the X console. I've tried various options in /etc/default/acpi-support, but the best I can do is have it resume normally if I force it to never chvt back to X. Anyone successfully get suspend/resume to work with 8.42 and an R5xx part?

            • Ok now some tests!
              It's so sad to show how our waiting hasn't been usefull to anything.
              The results are for Slackware 12.0, Radeon 9600 All in Wonder Edition:

              Driver Radeon Open Source 6.6.192

              1) Compiz + AIGLX runs better than any other solution/driver
              2) Glxgears -> about 1180 FPS
              3) Unreal Tournament 2004 3334 demo-> about 110 FPS (in a particular static situation)
              4) Xmame - Opengl with a particular rom -> always 53/53 FPS

              Driver fglrx 8.42.3

              1) Compiz + AIGLX runs worst than any other solution/driver
              2) Glxgears -> about 1580 FPS
              3) Unreal Tournament 2004 3334 demo-> about 200 FPS (in the same particular situation of open source driver)
              4) Xmame - Opengl with the same particular rom used in radeon open source driver test-> about 40/53 FPS

              notes: fgl_glxgears is about 330 FPS

                • A little more to add from previous post:

                  The Catalyst Control Center appears to work. My remaining issue is to get the component video output to work as I normally use my HDTV as my main monitor for my HTPC. Unfortunitely The Catalyst Control Center does not display any HDTV supported formats in the "Display Manager>TV(2)>Formats" page.

                  Getting my HDTV displaying under Linux is the only thing holding me back from completely dumping Microsoft Vista. Under Windows version of the ATI Catalyst Control Center getting my HDTV to display is very easy. I have tried the command line "aticonfig --add-cvmode=..." command to set the Component Video modes but all get rejected, I suspect because my HDTV does not return any EDID information.

                  From what I gather from many net searches no one else seems to know how to set up a component video enabled xorg.conf while using ATI drivers (fglrx).

                  So close but yet so far...

                      Did you try to use aticonfig from the command line?
                      Code:
                      TV Options:
                        --tvf, --tv-format-type=STRING
                              Change the TV signal format.  STRING can be one of:
                                 NTSC-M 
                                 NTSC-JPN
                                 NTSC-N
                                 PAL-B
                                 PAL-COMB-N
                                 PAL-D
                                 PAL-G
                                 PAL-H
                                 PAL-I
                                 PAL-K
                                 PAL-K1
                                 PAL-L
                                 PAL-M
                                 PAL-N
                                 PAL-SECAM-D
                                 PAL-SECAM-K
                                 PAL-SECAM-K1
                                 PAL-SECAM-L
                              Note: Not all graphics cards support every mode. Regional 
                                    settings are applicable. 
                        --tvs, --tv-standard-type=STRING
                              Change the TV standard for TV output.  STRING can be one of:
                                  VIDEO
                                  SCART
                                  YUV
                       --tv-overscan={on|off}
                             Enable or disable overscan mode for TVout
                             Note, not all tv-formats support overscan. Try to 
                             toggle overscan off before changing tv-format if 
                             and error occurs. 
                       --tv-info
                               Print out the current tv geometry, tv format, and if the
                               tv is physically connected. 
                       --tv-geometry=WIDTHxHEIGHT{+|-}X{+|-}Y
                                    =WIDTHxHEIGHT
                               Change the size and position of the TVout display. 
                               WIDTH and HEIGHT are in percentage units. Please note
                               that the valid range for WIDTH and HEIGHT depends on
                               the tv-format selected. However, as a rule of thumb  
                               WIDTH and HEIGHT are valid in the range [1,100]  
                               X and Y are pixels offsets from centre 
                               of the screen. X and Y are have variable ranges dependant 
                               on ASIC. Use tv-info to get valid X and Y ranges 
                               If tv-geometry is invoked with just width and height 
                               then X and Y are assumed to be 0
                               See example 5 below for a sample usage.
