Description Laurent Bigonville 2008-01-07 13:47:44 UTC

Hi,

With googleearth I get:
do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try running with LIBGL_THROTTLE_REFRESH and LIBL_SYNC_REFRESH unset.

and it takes age to start.
After that googleearth run quite smoothly.

radeon driver version: 6.7.197
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]

Please attach (as opposed to paste) the full xorg.conf and Xorg.0.log files and the output of xrandr --verbose. Which version of Mesa are you using?

Comment 6 Michel Dänzer 2008-02-27 08:12:40 UTC

Does this also happen if another 3D application (e.g. glxgears) is running when you start Google Earth?

Comment 7 Arkadiusz Miskiewicz 2008-02-27 08:47:04 UTC

Happens for me too. 

mesa 7.0.2/xserver 1.4.0.90/ati git driver from 20080227 (post 1.6.8), kernel 2.6.24

Setting: <option name="vblank_mode" value="0" /> in drirc makes googleeart start (but machine locks up later)

Comment 8 Arkadiusz Miskiewicz 2008-02-27 08:56:43 UTC

More info, X600 mobile radeon, XAA.

Tried running googleearth while glxgears was already running - no change. Still got 
"do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try running with LIBGL_THROTTLE_REFRESH and LIBL_SYNC_REFRESH unset."

In my case this is like: googlearth &; splash shows; do_wait error is displayed on console and it looks like it never progress - splash is displayed all the time.

Comment 9 Michel Dänzer 2008-02-27 09:23:28 UTC

After getting some more information on IRC, it looks like this is a Mesa bug related to whatever extension Google Earth uses for sync-to-vblank (sync-to-vblank seems to be generally working, e.g. using the vblank_mode driconf setting). It would be interesting to know if this still happens with the mesa Git master branch.

Comment 10 Laurent Bigonville 2008-02-27 09:45:32 UTC

still happening with 7.0.3~rc2

Comment 11 Arkadiusz Miskiewicz 2008-02-28 01:31:06 UTC

applied on top of 7.0.2 fixes (or workarounds) the problem for me.

Comment 12 Michel Dänzer 2008-02-28 02:45:56 UTC

Fix backported to 7.0 branch, it'll be in the 7.0.3 release.
